Engineering gantry crane can be divided into mechanical parts, electrical control system. Mechanical parts include metal frame, crane steel body, trolley mechanism, hoisting mechanism, etc., the electrical control system includes the control box, load meter, etc., as follows:
Crane traveling mechanism include wheelsets, frames, rail guides, lubrication systems, motors, reducers, brakes and more.
Trolley mechanism include the wheel set, frame, anti-skid device, lubrication systems, motors, reducers, brakes, etc.
Hoisting mechanism includes hook, wire rope, reel, pulley block, brake, reducer, motor.
Electrical system includes control box, load tester, wind speed tester, opening meter, lighting system, lubrication control system, etc.
Metal structure part includes the bridge, legs, beams and so on. Common two metal structure of Engineering gantry crane is truss beams, box beams, metal structures need to bear the beam weight, lifting cargo weight, wind load and other forces, so the stiffness and stability of the metal structure must meet the requirements.
