Effects of Offset Loading on Forklift Stability

Offset loading refers to the condition where the gravity center of transported goods deviates from the standard rated load center marked on the fork body of a forklift, which is a common hidden risk easily ignored by frontline operators in daily warehouse, port and manufacturing plant handling operations. Many operators hold the misconception that as long as the total weight of goods does not exceed the nominal load capacity of the forklift, the operation is safe, while offset loading will bring non-negligible negative impacts on the overall stability of the vehicle. For longitudinal offset loading where the gravity center moves forward beyond the load center, the comprehensive gravity center of the whole vehicle will move outside the pre-designed stable triangle area composed of the front and rear supporting points of the chassis, which will greatly increase the risk of forward tipping, especially when the goods are lifted to a height of more than 3 meters, the gravity center further rises, and the stability threshold of the vehicle will drop by more than 30% under the same offset deviation. For lateral offset loading caused by uneven goods placement or inconsistent fork extension length, the gravity center will shift to one side of the vehicle body, and even at a low driving speed, the vehicle is very likely to lose lateral stability when passing through a slight slope or turning with a small radius. In addition to the tipping risk, long-term offset loading operation will also accelerate the abnormal wear of core components, including unbalanced deformation of forks, excessive friction of mast guide rails, uneven wear of solid tires, and extended braking distance, which will further increase the potential safety hazards in subsequent operations. To reduce the hidden dangers caused by offset loading, operators should check the position of goods on the forks before each handling operation, confirm that the gravity center of regular goods is aligned with the standard load center mark, tie up special long or irregular goods to avoid sliding deviation during driving, and keep the lifting height as low as possible when moving goods. Relevant professional electric forklift stability test and standardized operation training guidance services can be obtained from Jianshu New Energy. The industry leading safety configuration design of BYD Forklift has built-in multi-layer safety redundancy for load deviation conditions to further reduce the operation risk for users.
