The lifting system consists of internal and external door frame, cargo fork frame, retaining shelf, lifting 

cylinder, inclined cylinder, lifting chain and so on. It is the holding mechanism of forklift truck for loading 

and unloading operations. Forklifts are standard with a three-stage wide view frame. 

8.1 Internal and external door frames 

The three-level wide view frame is composed of an outer frame that cannot be lifted and lowered and 

two inner and middle frames that can be telescoped up and down. The lower part of the outer door frame 

relates to the drive axle, and the weight is mainly supported on the axle housing. The middle and outer 

inclined cylinder support of the outer door frame relates to the piston rod of the inclined cylinder, and the 

door frame can be tilted forward and backward by operating the multi-way valve. The inner and middle 

frame is a welded piece, which bears longitudinal and transverse loads through rollers and side rollers, 

and makes the frame move smoothly. 

8.2 goods fork 

Fork frame is equipped with rollers and adjustable gap side rollers, so that the fork frame along the inner 

edge of the channel steel smooth up and down movement, fork frame each side of the roller has three 

groups, fork mountain to the maximum height, above a pair of rollers will extend out of the inner door 

frame edge. Fork by hook hanging on the fork frame, and lock pin locked in the fork frame beam groove, 

fork spacing available manual adjustment, fork and fork frame using international standards (ISO) in 

order to universal and interchangeable. 

8.3 Adjustment method of chain tightness 

- Drive the forklift to a flat surface and lower the fork to the ground. 

- Position with hinge bolts on one side of slide frame. 

- After adjusting the length of chain section of hinge bolt on one side of lifting cylinder, tighten the nut on 

one side of lifting cylinder. 

- At 1 meter above the ground, push the chain with your finger (about 5 kg force) so that the chain can 

move 20 mm.

 

9 Electrical System 

The electrical system mainly includes battery, traction motor, pump motor, traction motor controller and 

pump motor controller, handle joystick, multi-way valve block controller, display instrument, combined 

control switch, instrument and lighting device, etc. 

9.1 the display 

The display has six built-in red liquid crystal displays, which provide the operator with some easy 

information about the operation of the vehicle's mechanism. Parameter adjustment key (left turn) 2. 

Speed mode switch key/Parameter Adjustment key (upturn) 3. Parameter adjustment key (right turn) 

4. Parameter Adjustment button (Scroll down) 5. Parameter Adjustment button (Confirm) 6.7. Parking
