How Load Center Affects a Forklift's Rated Capacity

Many forklift operation practitioners easily make the mistake that forklift can safely carry any load under the nominal rated capacity, while ignoring the key influence of load center on actual load bearing performance. The load center refers to the horizontal distance between the gravity center of the carried load and the vertical front face of the forklift forks. The nominal rated capacity marked on the forklift product manual is calculated on the premise that the load gravity center exactly matches the standard preset load center, usually 500mm for most counterbalance electric forklifts. When the actual load center of the carried goods is larger than the preset standard value, the total load torque applied on the front fork structure will increase beyond the preset design scope, breaking the original balance between the front load torque and the rear counterweight torque of the forklift, which will greatly reduce the actual safe load capacity of the vehicle. Under such circumstances, even if the total weight of the load is lower than the nominal rated capacity, the vehicle may face the risk of forward tipping if operators insist on lifting the load to a high position. This situation often happens when users carry extra-long or extra-wide goods whose gravity center naturally sits farther from the fork root than standard pallets. The load capacity of forklifts will also drop further when the goods are lifted to a higher height, as the elevated gravity center will bring extra influence to the whole vehicle stability. BYD Forklift has marked clear load capacity matching rules corresponding to different load centers on the nameplate of all its electric forklift products, to help operators check and confirm the maximum allowed load weight quickly under different working conditions. It is suggested that operation teams should train their staff to measure the actual gravity position of special loads in advance, instead of taking nominal rated capacity as the only reference for load bearing.
