1: The selection of plate chain models produced by Runlite Machinery should comply with the design regulations, and plate chains of various specifications should be used within the limited lifting range. 022: Ensure that the chain is clean and free of impurities. At the same time, the surface of the groove wheel should be cleaned well. In particular, wear impurities should be obviously cheap during operation, such as cement ash, welding splashes, etc. 023: When installing the plate chain, the forklift is parked on a flat site, the gantry is vertical, the fork is lowered to the ground, and the lifting cylinder piston is lowered to the bottom point. The end joint of one end of the plate chain is linked with the front end fork frame, and the nut is locked, and then the chain bypasses the groove wheel, and the end joint of the other end is connected with the lifting cylinder block flange or the outer door frame beam at the rear end, and the length of the chain is adjusted through the nut. After installation, 50N force is applied to the chain at a position 1m from the ground. The horizontal movement distance of the chain is less than 20mm, and the installation is qualified. In the same way, install another chain. After the root chain is installed and adjusted, the fork rack should be lifted to check the tightness of the two chains. The length of the plate chain should be adjusted when the fork rises to the lifting height (that is, the lifting cylinder piston rises to the upper limit |). 024: The chain should ensure that it slides freely in the groove wheel, no distortion, and no jamming during the up and down operation of the chain. Collision and friction between the end face of the pin shaft and the groove wheel. 5: After the installation is completed, it should be oiled. The lubricating oil should be filled with the gap between the chain plate and the pin shaft to ensure its good lubrication. At the same time, it should be confirmed that all fasteners are fastened and the chain load is uniform
