Abstract
The method is for testing load equipment. A trolley is provided that has a housing with an upwardly sloping front segment and an upwardly sloping rear segment. Upwardly directed weights are stacked side-by-side on the front and rear segments so that the weights lean towards each other. The trolley is stopped by engaging the brake support against the ground so that the front segment is substantially parallel to the ground. Weights are added or removed from the trolley by downwardly inserting or upwardly pulling, respectively, the weights without removing any of the wheels. The trolley is connected to lifting equipment. The lifting equipment lifts the trolley from the ground.
