Each terminal in the control cabinet is arranged at the front to facilitate maintenance. The cranes are respectively equipped with power circuit, a control circuit, and an auxiliary circuit.The trolley’s power supply is mounted on the conductive side. Power supply for trolley: Single pole type trolley wire is used for power supply, and the travel distance is about (the actual working condition of the owner) m, and the power status indicator needs to be installed.Six electrical parts requirements of the semi gantry crane: The crane also has safety protection devices such as overload protection and limit of various institutions. The crane power supply adopts AC 380V 50Hz, the cart uses the safe trolley wire to supply power the electric hoist uses the cable to supply power. The gear shafts are mounted on machined beams. The speed reducer adopts a closed speed reducer. Track models use the Chinese industry standard YB/T5055. The top of the crane uses double-rimmed wheels and the bottom uses rimless wheels the buffer uses rubber buffers. The wheel material uses cast steel wheels according to ZG340-640. The whole machine has 4 wheels, 2 wheels on each side, and 1/2 drive.
The crane trolley traveling mechanism consists of the active wheelset, passive wheelset, and cross beam. The components can be relatively independent in structure and easy to maintain and adjust. Lifting mechanism of the semi hoist machine using the electric hoist as the operating lifting crane, mainly consists of cone rotor motor, reducer, reel device, coupling, guide rope, hook device, electric trolley, drive device and electric appliance and other components.
The force is concise and clear, and the appearance is elegant. The legs are welded in the form of a box structure.One end of the main beam and the cross-section rectangular cross-section leg and the lower cross-member are bolted, and the other end and the upper cross-member are also bolted to facilitate disassembly.The main beam is in the form of single main beam structure, and an electric hoist is hung under the I-beam of the main beam.The steel structures are mainly composed of main girders, outriggers, lower beams, upper beams, and ladders.Planning Tests for Paints and Clear Films (GB9286).
