Double beam bridge crane is a common industrial lifting equipment with the characteristics of sturdy structure, strong load-bearing capacity, and high lifting efficiency. The following is a detailed introduction to the structure and transmission principle of the double beam bridge crane:
structure
Main beam
Double main beam: composed of two parallel main beams, usually made of high-strength steel. There are tracks installed on the main beam for the movement of the lifting trolley.
Cross beam: Connect two main beams to increase structural stability.
End beam
Installed at both ends of the main beam to support the entire bridge structure. The end beam is equipped with driving and driven wheels for the movement of the bridge on the track.
Small frame: installed on the main beam and moves laterally along the main beam track.
Lifting mechanism: including electric motor, reducer, winch, and steel wire rope, used for lifting and lowering heavy objects.
Sling: Connected to the end of a steel wire rope, used to grab and secure heavy objects such as hooks, grab buckets, etc.
Driving system
Drive motor: Drive the bridge to move longitudinally along the track through a reducer.
Drive wheel: installed on the end beam, driving the bridge to move on the track.
Electric control system
Including control cabinets, cables, contactors, relays, frequency converters, etc., used to control the operation and operation status of cranes.
Operation room: The operator operates the crane through the control panel in the operation room.
Safety devices
Including limit switches, emergency stop buttons, collision prevention devices, overload protection devices, etc., to ensure the safe operation of the crane.
Summary
The structure of a double beam bridge crane includes the main beam, end beam, lifting trolley, driving system, electrical control system, and safety devices. By understanding its structure, better operation, maintenance, and troubleshooting can be carried out to ensure the reliability and safety of the equipment.
