Forklift truck hoisting system maintenance and repair

Forklift truck hoisting system is a device for loading and unloading work directly forklift truck, cargo unloading, stacking and ultimately by its completion, so it is the most important part of the forklift truck. Often need to strengthen the conservation and use, in order to maintain a good technical condition of it.

Disassembly and assembly and adjustment

The inner, outer door frame. battery forklift trucks‍ truck hoisting system between each main component, have relative motion. Wherein the inner and the outer door frame composed of a kinematic pair, fork frame and inner frame composed of a kinematic pair. In order to improve the motion accuracy of kinematic pair, the decrease of the friction between the moving member, reducing vibration and noise, improve the lateral stability of vehicle unloading goods fork, both inside and outside the door frames and forks on both side roller adjusting shim. Through the shim adjustment, so that a gap between the cargo fork frame side roller and an inner door frame, door frame gaps between the roller and the inner and outer door frame, if the relative motion freely, the gap value is not greater than 1mm. When the gap between the roller or coincidence type gantry clearance exceeds the specified by the design, roller to be adjusted or replaced, to ensure that the clearance of rolling or sliding, reduce the impact sound, to prevent the goods from sliding out of the goods fork. The door frame section flange size (thickness) reduced by more than LMM or the whole door frame combined lateral dimensions (width direction of the vehicle) is greater than a specified size more than 2.5mm, the emergence of the door frame deformation and warpage, are required to replace the door frame, in order to ensure the safe use.

The guide pulley and the lifting chain. Chain assembly, two chain tensioning force should be equal, load as evenly as possible, not to have the distortion phenomenon, the two sprocket after installation, flexible rotation. The pairing of the two forks, fork length should be approximately equal thickness. Two fork vertical section and horizontal section angle should be consistent. Two fork mounted on a fork, a plane on which should be kept in the same plane. The adjustment of the maximum length of heavy chain should be in the fork to the maximum lift height (i.e., lifting oil cylinder piston rises to an upper limit) when, after the adjustment of the hoisting chain should not be too tight, usually at the height of LM, with 5ON force on the chain, the deflection of 2Omm maximum as qualified. Each maintenance, dealing with inner and outer door frame channel steel and the chain sprocket grease, to ensure good lubrication, reducing friction of kinematic pair. In the wide field of vision in the hoisting system, the two lift cylinder (cylinder) stroke should be equal, the oil inlet pipe of each should be smooth. Two cylinder plunger rod end should also contact with the inner door frame, a sprocket support.

Fork. As the installation size hook and a fork between the standardization, linked to various attachments are the same and fork. So the plate fork frame can be conveniently replaced attachments. In order to make the fork or attachments from the fork frame is on or off, when the fork is provided with a file Shelves, can use the middle lower plate gap disassembly fork. In order to make the fork or attachments on the positioning frame and fork fork to adjust the spacing, can use a plurality of positioning upper plate symmetrical hole and a positioning groove, the positioning pin positioning by fork upper with spring. When the fork is hinged type, fork frame made of a sliding rod type, in the fork is arranged in the frame around the two round shaft, one on each circular sleeve fork, fork can slide on a round shaft, to adjust distance between the two forks, assembly and disassembly fork, need to be circular shaft next, fork is used card pin on the circular shaft.

Fork. The installation should pay attention to the selection of Lpg Gas Forklift Truck‍. The pairing of the two forks, fork length should be approximately equal thickness. The angle between the two fork vertical section and horizontal section should also be consistent, fork mounted on a fork, two forks on the plane should be kept in the same plane, should not be high and low dislocation phenomenon.‍
