Heavy-duty truck lifts are core equipment in repair shops, but improper operation can lead to serious accidents. Here are three frequently overlooked yet potentially fatal mistakes:
Overloading Operation
Many operators think "going slightly over the limit occasionally won't hurt," but the rated load capacity of a heavy-duty truck lift is strictly calculated. Overloading can not only cause hydraulic system failure but may also lead to equipment tipping due to center-of-gravity shifts. In one documented case, a slightly overloaded truck caused the lift to overturn during operation due to rearward weight displacement, injuring nearby workers.
Working Without Locking Mechanisms Engaged
After raising the vehicle to the desired height, operators must ensure mechanical locking devices are fully secured. Some skip this step to save time, relying solely on hydraulic pressure to maintain height. If the hydraulics fail, tons of truck weight can free-fall catastrophically. One repair shop narrowly avoided casualties when an improperly locked lift dropped a truck, crushing its chassis.
Neglecting Daily Inspections
Seemingly minor issues like leaking hydraulic hoses can suddenly rupture. Always inspect hose connections before each use and replace hydraulic fluid regularly (recommended every 500 hours or 6 months).
