The necessary components in the lifting mechanism of underhung bridge crane include the following parts:
Wire rope or chain: used to connect lifting objects to the crane and assume the role of lifting and suspending the lifting objects; chains are generally used for heavier lifting objects, while wire ropes are suitable for larger tonnages.
Drum: The drum device on sevencrane underhung bridge crane realizes the lifting movement of lifting objects by winding and unwinding wire ropes or chains.

Lifting mechanism: including lifting motor, reducer, brake and other components. The lifting motor provides power for the lifting process, the reducer is used to reduce the transmission, and the brake is used to control the stopping and holding of the lifting object.
Lifting hook: used for hanging lifting objects, usually made of steel material, with sufficient load-bearing capacity and safety.
Transmission system: including transmission gears, chains and other components, which transmit power to the lifting mechanism through the transmission device to achieve lifting movements.
Suspension devices: Suspension devices include hooks, lifting clamps, etc., which are used to firmly fix the lifting objects on the lifting mechanism to ensure safety during the lifting process.
The structural characteristics of industrial underhung bridge crane mainly include the following aspects:
Bridge: The bridge of the hook bridge crane consists of two supports and a main beam spanning above them. The main beam is equipped with an electric trolley for lateral movement and transportation of goods. The bridge can move, lift, rotate, etc. during operation.
Lifting mechanism: The lifting mechanism of underhung cranes is mainly composed of hooks, ropes and transmission mechanisms. It can move up and down along the main beam to achieve vertical lifting and horizontal movement of goods.
Control system: The control system of underhung cranes includes electrical control boxes, operating consoles, remote controls, etc. Through the control system, the operator can precisely control the various movements of the crane.
Compared with other types of cranes, heavy duty underhung bridge crane have the following advantages and characteristics:
Large span: Underhung cranes have strong spanning capabilities and are suitable for situations where large-span operations are required.

Wide range of operations: Underhung cranes can move vertically and horizontally to meet a variety of operating needs.
High flexibility: Because the lifting mechanism can move up and down on the main beam, underhung cranes have high flexibility and can adapt to a variety of operating requirements.
In general, heavy duty underhung bridge crane are powerful and flexible lifting equipment that are widely used in hoisting, moving or loading and unloading operations of general cargo, large mechanical equipment and other objects.
