The lift system lift system includes a motor and a gearbox. The brakes are housed in the gearbox. The cable winch is mounted on two base bearings. The output of the gearbox is transmitted to the two bearings via a shaft. The column and guide rail 1 column consists of 4 sections of steel. The lower part of the column is installed on the ground at the bottom of the pit, and the upper part is installed with a beam and a top plate. The lifting rail is installed in the middle of the two columns. The control panel and the transfer table are mounted on the lifting platform. 2 The top structure is mounted on the upper end of the column and consists of welded steel. The cable pulley is fixed here. The top guide wheel and maintenance platform are installed here. 3 The straightness of the lifting rail of the cargo platform is not more than ±2mm. The parallelism of the two rails after assembly is not more than ±2mm, and the deviation of the verticality of the lifting rail from the ground is not more than ±3mm.4 There is a steel structure rain in the upper part of the column. The shed and the upper part of the 5 column are equipped with a pulley bracket device to facilitate lifting equipment during maintenance or repair.
Lifting cargo platform 1 The lifting cargo platform consists of a platform frame and a welded structural frame. Both the cable pulley and the gripping device are fixed here. The guide wheels provide guidance for vertical movement. The roller table is mounted in the cargo bed. The cargo platform has pedestrian walkways and handrails. 2 The cargo bed is installed between the two columns and is driven by a lifting mechanism such as a wire rope to move up and down along the column guide rails. 3 grasping device: the grasping device is a safety device installed at the left and right ends of the platform. When the descent speed is too fast, it starts the roller that grips the guide rail, thereby stopping the platform movement. The gripping device has a synchronizing device, and when triggered, both sides act simultaneously. The gripping device is connected to the speed controller. 4 speed controller: consists of a restricted disc, a pendulum lock wheel and a cam spring with a V-shaped groove for the control cable. When the trigger speed is reached, the high rotational speed causes the catch and the lock wheel to bite, restricting the disc and the control cable from locking, and finally stopping the wheel. The roller table 1 roller table is mounted on the loading platform of the hoist, and the pedestrian pedal made of the patterned steel plate is placed between the rollers of the roller table. The roller table roll is made of cold-rolled seamless steel pipe, and the ends of the roller are bearings, which are driven by a motor and a chain. The support guide groove of the roller table is provided with access guides at both ends. A baffle is provided at both ends of the table. 2 Roller drive: The roller drive consists of a gear motor, a brake, and a double sprocket on the motor shaft. The double sprocket drives the direct power roller through the chain. The other rollers are thus driven directly by the wheels. 3 motor brake: The motor brake is a spring disc brake. Release the brake coil in the coil 匣. The working clearance is controlled by a hex bolt and the brake can be released by the brake contact screw. The 4-roller table is mounted on the lift truck.
