The accessories for gantry and bridge cranes refer to parts and attachments used for these types of cranes. These accessories could be for maintenance purposes, repairs, or for enhancing the functionality of the crane. There are many different kinds of accessories, and here are some common ones along with their functions:

Wire Rope – Used for lifting or lowering the load, a critical component connecting the hook and the crane structure.

Hook – Used to attach the load to be lifted, the part that directly interacts with the cargo.

Motor – Acts as the power source for the crane, mainly used to drive lifting, trolley movement, and bridge travel.

Gearbox (Reducer) – Reduces the output speed of the motor to increase torque, meeting the operational speed requirements of the crane.

Brakes – Ensure that the crane can stop safely during parking or in an emergency situation, maintaining the stability of the load.

Pulley Block – Changes the direction of the wire rope and can increase lifting power.

Controller – An electrical component used to control the actions of the crane, such as lifting, driving, and trolley operation.

Limit Switch – Ensures the operation of the crane within safe boundaries, including height limiter, travel limiter, etc.

Electrical System – Includes cables, conductor bars, contactors, circuit breakers, frequency inverters, etc., providing necessary power and control for the crane.

Running Gear – Includes wheel assemblies, bearings, etc., used for supporting the movement and positioning of the crane structure.

Safety Equipment – Such as load limiters, emergency stop switches, overload protectors, etc., ensuring the safety of lifting operations.

Remote Control – Allows for remote operation of the crane, improving the convenience and safety of operations.
