Selection and Installation
The weight, center of gravity position and rear suspension distance of the forklift counterweight are determined by the overall vehicle layout. Among them, the selection of the counterweight mass mainly considers the longitudinal stability of the forklift when it is fully loaded for stacking and fully loaded for driving. The mass of the counterweight directly affects the protection coefficient of the front and rear balance of the forklift, and is the main parameter determining the protection coefficient of the forklift. When the total mass G of the counterweight is determined, based on the assembly form of the counterweight on the frame, the accurate and clear installation dimensions of the counterweight can be determined. There are two inverted V-shaped suspension blocks on the upper outside of the forklift tail frame, and the counterweight is fixed on them with two bolts.
2. Ventilation holes
Since thermal balance is a crucial parameter for forklifts, poor heat dissipation can easily lead to excessively high water temperature in the engine, which adversely affects the overall performance of the forklift. Therefore, the position of the ventilation holes in the counterweight, the air ducts, and the air flow direction become extremely important. The higher and larger the ventilation holes are, the more conducive they are to heat dissipation; the use of rounded corners between the ventilation holes and the radiator helps with air flow direction and improves the heat dissipation performance.
3. Departure Angle
The departure angle at the lower end of the counterweight is also very important. This angle is mainly designed to balance the friction between the lower end of the counterweight and the ground when going up or down slopes. Theoretically, the departure angle should be equal to the specific vehicle's large climbing angle. The position of the cutting point of the lower end of the counterweight needs to be determined based on the large climbing slope of the specific vehicle and the rear suspension length of the counterweight.
