Overhead cranes sometimes also called bridge cranes and eot crane, which are cranes with a hoist or winch traveling along the bridge beween parallel runways. They are designed to meet the medium to heavy industrial lifting requirements, covering all parts of the manufacturing process.
Types:
overhead cranes consist of a wide range of cranes including:
• Overhead crane for laddle lifting capacity up to 600t;
• Overhead crane for steel factory capacity up to 600t;
• Overhead crane with grab lifting capacity up to 50t;
• Overhead crane with hoist lifting capacity up to 80t;
• Overhead crane with magenet lifting capacity up to 50t;
• Overhead crane with winch lifting capacity up to 300tons;
• Overhead crane with chain hoist lifting capacity up to 30t;

Safety Measures |
Foundation |
1. |
Loss of phase /voltageprotection |
1. When the voltage/phase is too low, the electricity will disconnect |
2. |
Over Voltage, over current protection |
1. When the voltage/phase is too big, the electricity will disconnect |
3. |
Overload Limit Switch |
1. When the lift capacity is more than the max rated lift capacity, the electricity will disconnect, crane will stop work |
4. |
Weight limit |
1. Supervise the decrease of hook. There is a limit height. The hook cannot fall any more if reach this limit |
5. |
Fire limit |
1. Supervise the up and down limit position of Hook. Avoid the over increase and over decrease |
6. |
Crane Travel Limit Switch |
1. Supervise the travel of crane, and stop crane travel more than rated travel distance. |
