Electric forklift structure diagram and principle

 

 

Method / step

The fork is a fork-shaped member that directly carries the cargo. It is mounted on the fork frame by hooks. The distance between the two forks can be adjusted according to the needs of the work and locked by the positioning device.

 

Electric forklift structure diagram and principle

The fork frame is a structural member welded by steel plate, and has a roller group. The inner side of the inner door frame has a groove-shaped track in the up-and-down direction, and the fork frame and the inner door frame are connected in the same manner, and can also be used only along the track of the outer door frame. Move up and down.

 

Electric forklift structure diagram and principle

The inner gantry is a frame structure in which two trough-shaped types are welded as a column and a girders. Its lower part is hinged on the drive axle (front axle) of the forklift, and the gantry can be tilted at an angle in the front-rear direction by means of the tilting hydraulic cylinder. The gantry is tilted forward for loading and unloading. The purpose of the backward tilting is to prevent the cargo on the fork from slipping when the forklift is running.

 

The lower end of the lifting hydraulic cylinder is on the outer gantry beam, and the upper end is coupled with the inner gantry beam and the sprocket. One end of the lifting chain is coupled with the lower part of the outer door frame, and the other end is connected to the fork frame by the sprocket. When the hydraulic oil is introduced into the hydraulic cylinder, the piston rod moves upward at the speed v and drives the sprocket and the inner gantry to the same. The speed v rises, and due to the principle of the moving pulley, the chain pulls the fork to lift at a speed of 2v. When the hydraulic cylinder is fully stroked, the inner mast is at the extreme position above the outer mast, and the fork is at the extreme position above the inner mast. When the oil pressure is released, the components such as the cargo or the fork are lowered by their own gravity.

Precautions

1. A driver who is trained and holds a driver's license can drive;

2. Check each control and alarm device before driving. If it is found to be damaged or defective, it should be operated after repair;

3, the handling should not exceed the specified load, the fork must be fully inserted under the goods, and the goods are evenly placed on the fork, not allowed to pick the goods with a single fork;
