Gantry Crane

FHMG400/75-33A4 gantry crane is a big sized product specially designed for outdoor lifting and moving large transformers. The main structure of the product adopts box frame construction, double-girder and single trolley with the M.H. rated lifting capacity of 400t, A.H. rated lifting capacity of 75t and span of 33m.

The gantry crane mainly comprised main girder, supporting leg, lower beam, grade one connection beam, grade two connection beam, travelling bogie, trolley, platform railing and electrical control system. The main steel structure, like main girder, supporting leg and lower beam, is connected by flange, which will quicken and facilitate equipment assembly and adapt to long and short distance transportation.

Lifting Mechanism

Trolley Mechanism
Diagram 1-1 Trolley Mechanism Layout Diagram
Lifting mechanism is consisted of motor, gearbox, brake, coupling and drum. Motor and gearbox adopt world famous band product. Coupling is the new model elastic coupling of plum blossom with excellent buffing and vibration absorption and long-term service life. Brake is the new model electric-hydraulic pusher brake with reliable performance and low trouble rate. Lifting mechanism adopts wire rope drum construction and lifting motor adopts variable-frequency motor which is managed by variable-frequency and speed regulation control system. Lifting mechanism is equipped with reliable brake system and dead space limit device wherein electric brake comes first and mechanical second. The layout of trolley mechanism is presented in the following diagram1-1.
