In daily material handling operations, the electric forklift counterweight system is a core component to maintain load stability and prevent tip-over incidents. Proper counterweight calculation supports operational safety, reduces equipment wear, and smooths on-site workflow, with all processes following general industrial safety guidelines for reliable performance.
The core of counterweight calculation relies on the classic lever balance principle, with the forklift’s front axle as the fixed fulcrum. On one side, combined torque comes from the rated load, front mast assembly weight, and forward-shifting center of gravity when the mast lifts. On the other side, stabilizing torque comes from the rear chassis weight and installed counterweight. For static calculation, operators collect core parameters: rated load capacity, standard load center distance, horizontal distance from counterweight position to front axle, and unloaded chassis weight distribution. The basic calculation balances torque on both sides, with a reserved stability margin adjusted for site conditions like ground evenness and slight slopes.
Static results require minor adjustment for dynamic working conditions, as forklifts accelerate, decelerate, turn, and lift masts during operation, generating inertial force changing real-time torque distribution. Correction coefficients are applied based on average travel speed, maximum lifting height, and maximum path slope. Initial results are verified through standard stability tests covering no-load travel, rated load lifting at set heights, and regulated-speed turning, to check tilt risks while ensuring total vehicle weight does not exceed axle and tire load ratings.
