Portable Cantilever Hoists

Whenever you need to be able to hoist or lift a weighty object from the floor onto a higher level, having a lifting system that you can rely on is essential. Unfortunately, there are always situations where it is simply not possible to use conventional lifting gear such as jibs or fork lifts, and under these situations, when it is necessary to be able to raise a weight quickly, then a cantilever hoist is often the best choice.
These small portable cranes are ideal for lifting heavy weights up to 4,000 pounds depending on the model, and are designed to be used in circumstances when other alternatives are unavailable. The high specification of the cantilever hoists offered makes them a formidable option for any workplace, and they provide a fully reliable and useful addition to any arsenal of equipment.
The standard cantilever electric hoist is a well made and sturdy device that can be moved easily into place wherever it is required, and then can raise heavy weights effortlessly thanks to its heavy duty hand pumped hydraulic pump lifting system that can lift 2,000 pounds onto a truck in seconds.
The principal concern whenever lifting heavy objects on an uneven surface is to ensure stability. The basic design premise of a cantilever hoist is to include a heavy counter weight that opposes the load and ensures longitudinal stability in use. This use of a counterweight is backed up by a relatively wide chassis on fully lockable 8 inches by 2 inches phenolic casters.

In order to offer additional support under circumstances where it is required, the cantilever hoist also offers a set of easy to set out riggers that ensure lateral stability under almost any conditions. Optionally, a ballast can be added for counterbalance, for added stability for heavy duty tasks.
The boom on the hoist is hard wearing and designed to last. It sits on a 360 degree rotating joint to allow for a weight to be hoisted off the ground and then swung effortlessly into the back of a truck or onto a raised working surface.
The key to efficient and safe handling of any heavy weight is control, and the cantilever hoists offered by easy rack are designed with this in mind from the outset. Aside from the sealed hydraulic system that has been created to ensure maximum lift and smooth action, the release of the system is also restricted so that it does not just drop the object into place.
Smooth lowering of the load means that it can be placed accurately and gently in order to protect both it and the surface onto which it is being lowered.
The main use for this lifting tool is undoubtedly in hoisting weights onto the back of a truck, but thanks to the ease with which it can be deployed almost anywhere in a matter of minutes, it is a useful back up for many situations, and can even be utilized for hoisting an engine block from a vehicle if necessary, as well as any other heavy lifting job that you need a tool you can rely on for.

Facts and History of Electrical and Electronic

The first significant application of controlled electricity in Cleveland was telegraphy, which made its appearance in the city in 1847 on the premises of the Lake Erie Telegraph Co. Fire-alarm boxes were the second useful manifestation of the “new” power in the city, and by 1865 there were 24 of them. The telephone came in 1877. Besides these communications uses, the other main areas of electric hoist industrial progress in the latter part of the 19th century were lighting, traction, and industrial motors, and in these areas as well, Cleveland’s technical-entrepreneurial talent was quick to perceive opportunities and act on them.

In the lighting field, CHARLES F. BRUSH was the most prominent innovator and entrepreneur of the period. His major contribution was the practical development and commercial exploitation of the arc light. Although the latter was invented in England in 1808, Brush devised its practical application by developing an improved dynamo to provide a steady current, and by making design changes in the arc fixture itself that improved the quality of the light and extended the working life of the carbon electrodes. He also redesigned the lamp’s circuit to make arc lighting possible from central stations. Hoisting equipment Brush began to sell small arc lighting systems in the late 1870s for use in stores, factories, and hotels. However, the potential of this equipment was first realized with Brush’s demonstration of its street-lighting possibilities on 29 Apr. 1879, in Cleveland’s PUBLIC SQUARE. The brilliance of the light produced by his 12 lamps caused a sensation and foretold the decline of the gas-lighting era. As a result, Brush sold central power stations to San Francisco, New York, Baltimore, Boston, and Philadelphia. In 1880 Brush bought the Cleveland Telegraph Supply Co., where he had done the developmental work, and renamed it the Brush Electric chain hoist. The battle between electric and gas lighting lasted some 30 years, and although advances were made in gas-lighting technology, electricity won out. During that time, CLEVELAND CITY COUNCIL, viewing comparative costs, voted to go back to gas light in 1883 but reversed itself 17 days later. About the time that Brush was developing his arc light, Thomas Edison designed a practical incandescent lamp which later had great significance for Cleveland, because the companies that formed the National Electric Lamp Assn. in 1906 centered much of their light-bulb production in this area. When NELA became the National Quality Lamp Division of GENERAL ELECTRIC CO., it established NELA PARK in the SUBURBS. The division took the leading role in GE’s incandescent lighting development program from 1915 until 1935, when fluorescent lighting research became prominent.

Basic Building Construction Equipment and Machines

Building construction equipments vary from the heavy, large equipment to the mobile, lighter equipment.
Hydraulic excavators, cranes, and concrete mixers are among the basic, hardworking equipments that any building construction company cannot function with.
Hydraulic Excavators
Hydraulic Excavators (also known as diggers or earth movers) are extremely large equipments utilized for multiple operations. They are utilized in applications such as construction of large structures and roads as well as in the mining industry. As one of the first equipment to be applied for readying the construction place, excavators level the land by burrowing and cutting ground. Hydraulic excavators are very functional for certain confined work sites which are less receptive to traditional construction equipment.
The excavator is made up of four basic parts-hydraulic cylinders, arm, bucket, and boom-all involved in loading and excavating. Interestingly, their movement is similar to that of a human arm. The boom acts similar to the upper part of an arm, together with shoulder and elbow. The excavator’s arm’s movement is likened to a human arm beginning at the elbow to the wrist. And, the bucket is likened to a cupped hand.
Hydraulic excavators consists of loaders, tippers and crawlers (bulldozers). A crawler is a very robust tractor fitted with a dozer blade. Most excavators feature crawlers since they’re more functional for operations on mud-covered, rough terrains as compared to wheeled ones.

Cranes
Cranes are equipped with pulleys and levers to haul up and lower sizeable weights. Basically, a crane has a telescopic boom or steel truss that hoists its portable base. Both the levers or pulleys lift the boom, and the boom typically has a hook hanging on it. There are several kinds of cranes including loader cranes and tower cranes. Loader cranes feature hydraulic power booms attached onto trailers. Booms load up materials onto the trailer and may be collapsed after use. Certain types of loader cranes feature telescopic boom for easy operation. Tower cranes are usually the tallest of all cranes. However, they do not feature portable base and parts need to be assembled. These cranes are largely applied to build tall structures and skyscrapers. Primarily exploited for the cutting down of workload, cranes can also perform lots of jobs including moving, digging and creating.
Concrete mixers or processors
Concrete mixers or processors are powered hoisting equipment used for mixing cement, water, sand, and gravel to create concrete. A concrete mixer is made up of a rotating drum, a motor, and a trough. The elements applied to create concrete whirls around thus mixing everything consistently.
Concrete processors come in various sizes from the extremely large industrial mixing truck to the smaller, handy concrete mixer. A small concrete mixer is ample for smaller amounts of concrete, up to 2 cubic yards. It’s normally run by electricity and features a wheeled base for easier transfer. Its drum can be tilted at an angle so that concrete can be easily dispensed onto the spot that needs to be cemented. A large industrial concrete mixer truck on the other hand, is applied for mixing as well as carrying big amounts of concrete for use on a construction place. These mixers are computer encoded for constant, accurate mix.
Technology indeed creates modern construction equipment to function efficiently, dependably and quickly.

Electric Chain Hoist Selection

Electric chain hoists are a valuable piece of material handling equipment when properly applied.
Below are some steps to help lead you to the correct type of electric chain hoist.
1.Is the hoist going to be in any special environments? If it is a special environment such as an explosive environment have the class, group and division if applicable. These are electrical specifications which will require special enclosures but you may also want to consider mechanical items such as bronze wheels, stainless hook, stainless chain, etc. These are not required to meet the electrical specification but can create sparks. Also note if it is high humidity, heat, or outdoors.
2.What will the duty cycle of the hoist. How many motor starts will you be doing? Remember if it is a 2 speed hoist that you will have twice the motor starts. Also of consideration is the location of the lift. That is will you be only lifting in one area of the chain or will your lifts all be different lengths. If a lift is all in the same location premature failure of the chain can happen. If the duty cycle is too severe you may want to consider a wire rope hoist. Variable frequency control can also alleviate the situation as you do not have contactors or the number of motor starts a two speed hoist will have.
3.What type of hoist suspension do you need? If the hoist is going to be hung from a single point you can consider a top hook hoist which will work nicely with a beam clamp. It can be moved when needed. If you need travel along a monorail or across a bridge crane you will want to either consider a plain push trolley or a motorized trolley. A plain push trolley is economical and normally not a problem with loads under 2 tons but it can be harder to stop the load once you get it going and it will not brake and can drift easier than a motorized trolley. If you have a large load, are doing it many times a day or need positive braking then you will want to consider a motorized trolley.

4.Next you need to look at the particular job you are doing. Do you need precision such as setting down a delicate part or are you just doing regular maintenance or fabrication. If you part is expensive, delicate or takes precision placement then you will want to look at variable frequency control on the hoisting motion. If you just need a little precision then consider two speed. Typically American made hoists have a 3 to 1 ratio and foreign hoists have a 5 to 1 ratio. So a domestic hoist with 15 fpm as the top speed will be 15/5 fpm. For general maintenance or fabrication a single speed works fine much of the time. The same control systems goes for the trolley. You can look at variable frequency control, two speed or single speed depending on the precision you need. A trolley brake is also an option to consider.
5.Depending on the horse power of the hoist motor a electric hoist will be offered in single or three phase power. If it is a heavier application you should use three phase power if it is available. Your miscellaneous components such as contactors and motor will run cooler and last longer. If it is a two speed unit, make sure and specify the three phase power as these hoists are not reconnectable. Specify it as 208-3-60, 230-3-60 or 460-3-60.
6.If the hoist is running on a bridge or monorail you will need to confirm the type of beam and size of the beam. You will need to know if it is a wide flange or I beam and the flange width as well as depth. Most hoist manufacturers now offer a wheel that can run on a wide flange or tapered tread of an I beam. In some cases it might even be patented track which will have a 3.33 inch or 3.25 inch lower flange and requires special wheels.
7.You will need to know how you are going to get power to the hoist. Typically it is done with a festoon system, which can be the c track type or tagline festoon. You can also use bar or a cable reel.
8.Looking at a brand that is made or widely distributed in the United States is a consideration if down time is an issue. Some of the foreign hoists do not have a wide distribution channel and thus parts are hard to find or take weeks to get. Many brands have extensive distributor networks so getting replacement parts is an overnight affair

Keep your forklift trucks in good running condition

We all know that a forklift is a truck fitted with a mechanized platform or with similar objects, which has the ability to lift, move, and deposit the materials loaded on it to a different place. Factories, landscaping outfits, electric hoist construction departments, warehouses or any other organization where the movement of materials is concerned, use these machines.

In addition to lighting, traction, and industrial applications, the electrical home-appliance field was richly represented in Cleveland by World War I. Heating-related appliances included coffee percolators, hotplates, frying pans, corn poppers, baby-bottle warmers, kitchen ranges, hair dryers, and radiant heaters. In addition, there was heavy production of vacuum cleaners, washing machines, fans, vibrators, and sewing machines.

By 1919 Cleveland led the nation in the production of electric batteries and vacuum cleaners (7 different makes of vacuum cleaners were being produced in the city in 1931). In the mid-1920s, Cleveland ranked 3rd in the production of radios, after New York and Chicago. Theodore A. Willard, whose WILLARD STORAGE BATTERY CO. was Cleveland’s largest battery producer, founded the city’s first high-powered radio station, WTAM. By 1938, the Willard Co.’s 15-acre plant, built in 1914, was turning out 15,000 batteries per day.
In the 1920s, John A. Victoreen, an inventive Cleveland radio amateur, started a radio parts business. Soon, however, his attention turned to radiation measurement, and he developed the Condenser R-Meter, an instrument for measuring accurately the intensity and total dosage of x-ray delivery, which gained international fame. Radiation measurement remained a central concern of the Victoreen Instrument Co., founded in 1928 in CLEVELAND HEIGHTS The company provided 95% of the instrumentation for the hoisting equipmet natomic bomb tests after World War II, earning itself claim to the title of “first nuclear company.”
Allen-Bradley, a Division of Rockwell Intl. in HIGHLAND HEIGHTS, is a long-established area firm producing programmable controllers and similar capital goods, incorporating electronics, for manufacturing industries. Keithley Instruments, Inc., based in SOLON, had its beginnings in a high-impedance amplifier, called the “Phantom Repeater,” invented by Joseph Keithley in 1946. This and other Keithley-developed instruments were manufactured for him by another firm for 5 years until 1951, when Keithley moved his operation to larger quarters and began manufacturing on his own. Sensitive measuring instruments remained the core of the company’s output, which came to include voltmeters, ammeters, digital multimeters, and complex testing systems incorporating both computer hardware and software. The company’s product-development path in itself traces some of the most important steps in the technological advance of electronics since the 1940s–vacuum tubes to discrete transistors to integrated circuits, and finally, to complex computer-linked systems that can handle the tasks of measurement and computation virtually simultaneously.

Hints and Tips For Making Car Lifts Safer

Because of the weight of the car and the height of car lifts, these machines can create some scary situations. Keeping safety in mind when working around these systems is a start, but good maintenance also helps. For added safety and usability, you can add additional car lift parts onto the original system.
Caring For Car Lifts
All styles of lifts need regular attention to ensure they work safely and hydraulic-style lifts are no different. First, check the fluid level in the machine and if it is low and needs it, add the oil eletctric hoist recommended by the manufacturer. You will also want to make sure the pistons and cylinders of the machine are clean and free from debris. You should lube any of the moving parts that need it according to your owner’s manual since each machine is different.
Hoses for hydraulic fluid are one of the most common breakdowns. You want to avoid having it leak while the vehicle is on the lift by check each one for leaks and damage. If a hose does start to leak while you have a vehicle on the hoist, stay back as far as you can and lower it gently. You can then fix the hose with the right car lift parts and check the entire system over before raising it back up. The controls and platform should also be tested regularly to make sure the system doesn’t malfunction while you are using it.

Safety Precautions During Use
Incorrectly loading the lift is a common and possibly deadly mistake. Most often, the machine has an uneven weight, or a load that is too heavy or too big. Center the vehicle on the platform and make sure you are aware of the size and weight rating for your particular hoist. The power should be off and the hoist locked after the vehicle is high enough to work with. Just be sure not to raise it past the recommended point. Don’t forget to put the emergency brake on in the vehicle as well.
Knowing the location of the controls and the proper way to use them is important in case you need to use them during an emergency. As you use the lift, whether it is to lower or raise the vehicle, keep an eye on the pressure gauges and movement of the electric chain hoist. If you happen to notice anything out of the ordinary, such as high or low fluid pressure or uneven movement, check the entire system over and repair it before you use it.
Car Lift Parts For Safety And Usability
Some models of car lifts aren’t the safest models available, but this doesn’t mean you can’t change that. For instance, one popular model is single post auto lifts. You can purchase a bolt on safety leg that has multi-positional locks. This makes the hoists safer to use and easier to work with.
Safety rules need to be practiced whenever you are near car lifts because one mistake can be deadly. You can also lower the risk of having an accident by caring and cleaning the machine regularly. Lastly, you can add on additional car lift parts to make sure your machine is as safe as possible. You will find these safety tips not only make your automotive lifts safer, but easier to use.

DIY Electric Vehicle Guide

If you are an electric car enthusiast, you will appreciate the benefits of owning an electric vehicle (EV). Anyone who has driven an EV for the first time will notice the smoothness and the power behind the acceleration. Unfortunately, a new electric chain hoist car on the market is still quite expensive and many people would not be able to justify the investment. The next option to having an electric vehicle is to convert your existing gasoline powered car to run purely on electricity. How do we retrofit a conventional automobile to EV? You start by getting a copy of Do It Yourself (DIY) electric vehicle guide.

Electric chain hoist, Electric hoist, Hoisting equipment, Bridge Crane, Chain Block, Lever Block, Electric Chain Hoist Manufacturer.

The concept behind an electric car conversion is to remove the internal combustion engine and replace it with an electric motor. Before you hoist up the engine, you have to disconnect all its associated components such as exhaust pipe, fuel lines, radiator, fuel pump etc. The electric motor is connected directly to the existing transmission unit. Your homemade electric car will then be fitted with 10 to 15 units of deep cycle batteries to power the motor.
If you are converting a car to EV for the first time, you will need the electric hoist vehicle conversion guide to show you the step by step procedure. Most guides will also come with a standard electric car plan. You may have to modify the design plan to suit your donor car model.
If you do not feel like doing all the hard work, you can outsource the conversion process to a professional automobile workshop. This is a better idea especially if you are not well versed with hand tools. By doing this, you will incur some additional cost but it will be money well spent.

Their line of tools is economically priced to give you power for your dollars. From their cordless drills to their largest floor model hoisting equipment, Chicago Electric power tools give you value for your dollar. They offer many tools you desire at bargain basement prices.
Chicago Electric power tools offer a wide range of equipment including corded and cordless equipment. They even have a few items for your workshop. Their band saw is popular with airplane kit builders. The offerings from Chicago Electric power tools include both corded and cordless drills, saws of all types, sanders and grinders. They offer both outdoor yard tools and household power tools. They even offer electric winches of various capabilities and an electric hoist. The variety that Chicago Electric power tools offer extends to some automotive related tools as well. A few bench based tools are offered also, like a compound miter saw.
Bands saws are used to cut thinner material into odd shapes with less wastage from the width of the blade. The thin flexible blade allows material to be cut with a radius curve smaller than you can get from a circular saw. With a band saw, you rotate the material as you cut it to achieve the curve you desire. It is possible to make a tool called a jig that will help you to achieve a very smooth curve reducing the amount of sanding needed to finish the piece.

Electric chain hoist, Electric hoist, Hoisting equipment, Bridge Crane, Chain Block, Lever Block, Electric Chain Hoist Manufacturer.

The band on the band saw being thin and flexible has a tendency to break while you are cutting material. When this happens, shut the machine off and replace the blade. Usually the blade will break at the point it was welded together and will not shatter into pieces. When you purchase replacement blades, spend the money necessary to get the best you can find. The welds will be stronger and the blade will last you much longer than cheaper blades will. Be careful when pushing material into the blade. Do not wear any gloves or loose fitting long sleeves when operating a band saw. The blade has a tendency to catch such items and draw the flesh under it into the blade cutting quickly and deeply. Whenever operating any equipment that electric chain hoist chicago power tools offers, wear protective eyewear to protect your eyes from flying materials.
