What should I pay attention to when using the mobile boarding bridge?

Release time:11-29Views:438

The mobile boarding bridge shall comply with the standards of the machinery industry. Lifting channels are generally divided into fixed lifting channels, mobile lifting channels, self-propelled lifting channels and forklifts. The working environment temperature is -15-40°C. Generally, the work table should be raised at a speed of 6-9 m/min, and the lowering speed should not exceed 6 m/min. Different types of mobile boarding bridges are slightly different. Calculation of elevator speed: elevator speed is equal to elevator height/(cylinder volume/pump station displacement). Other equipment of the mobile boarding bridge, such as brightness level switch, forced deceleration switch series, safety gear, guide rail, guide shoe, etc., may be changed due to speed. Of course, this must be related to the rating method of a particular elevator company.

The chain of the mobile boarding bridge should be filled with lubricant in time. Lubricating oil must enter the gap between the roller and the inner sleeve to improve working conditions and reduce wear. The tightness of the mobile boarding bridge chain should be appropriate, too tight to increase power consumption, the bearing is simply worn, and the loose chain simply jumps and loosens. After the sprocket of the mobile boarding bridge is severely worn, the new sprocket and the new chain should be replaced at the same time to ensure good meshing. You cannot replace a new chain or a new sprocket alone. Otherwise, it may cause the joint to deteriorate, and then accelerate the wear of the new sprocket or new sprocket. When the surface of the sprocket teeth is worn to a certain degree, it should be turned over in time (please see the sprocket for adjusting the appearance). Extend the use time. The old mobile boarding bridge chain cannot be mixed with some new chains, otherwise it will simply cause transmission shock and chain breakage.


The tightness of the chain is: lifted or pressed from the middle of the chain, the center distance between the two sprockets is about 2%-3%. After use, the mobile boarding bridge chain is too long or too long. It is difficult to adjust. The chains can be removed properly, but they must be uniform. The connecting rod should pass through the back of the chain, make sure that the piece is inserted into the outside, and make sure that the opening of the piece should face the opposite direction of rotation. The solenoid valve of the hydraulic pump station system of the mobile boarding bridge can adjust the speed appropriately. If it is adjusted to a larger scale, try to check whether the hydraulic oil of the mobile docking bridge is enough, whether the cylinder is leaking, etc. If there is no problem, the speed is still very slow. It is advisable to replace a larger pumping station system.
