The traveling mechanism of overhead hoist for moving goods adopts 8 sets of independently hydraulically driven and suspended modular wheel sets. Each set is mainly composed of slewing drive, cantilever, cantilever hydraulic cylinder, connecting arm, axle, tires, and hydraulic components. The maximum static load is 35 t, which can achieve ± 135° slewing, vertical direction ± 250 mm buffer, axle ± 6 left and right ° Yaw and other functions.
The hoisting mechanism of overhead hoist for moving goods is a typical wire rope hoisting mechanism, which is mainly composed of a motor, a coupling, a double drum and a double brake, etc., and is suitable for the combination of lifting weight and speed under various working conditions. The optimized pulley compensation design controls the height difference of the cargo horizontal track within the luffing range to 630 mm.
In order to obtain fast and stable speed and reduce the weight of overhead hoist for moving goods, the luffing mechanism adopts the technical scheme of hydraulic cylinder luffing. The maximum bearing capacity of the hydraulic cylinder reaches 130 t, and the power of the luffing mechanism is provided by the hydraulic pump station set on the turntable.
The rotation adopts double planetary reducer and internal gear transmission. The overhead hoist for moving goods needs to jack up the whole machine during normal operation, and the outriggers adopt a typical lateral telescopic H-shaped arrangement, which is mainly composed of telescopic beams, jacking hydraulic cylinders, and supporting pads.
