What must operators test when lifting near-capacity loads?

When lifting near-capacity loads, operators must test the brakes because the brakes are critical for ensuring that the lift can be controlled safely. When handling heavy or near-capacity weights, the pressure on the lifting mechanism and its associated systems increases significantly. Properly functioning brakes are essential to control the descent of the load and prevent accidents that could result from a sudden drop or loss of control.

Having strong and reliable brakes contributes directly to the safety of the operation, making it possible for operators to manage the load effectively, especially if they need to stop or adjust the lift position while in transit. This focus on brake integrity helps minimize risks associated with lifting heavy loads. Other choices, while important in their respective contexts, do not directly address the immediate safety concerns associated with lifting heavy loads. For instance, testing soil conditions is vital for determining the stability of the surface, but it is secondary to ensuring the lifting device can perform safely under load.
