Abstract
The wheel chock handling unit includes a base, an articulated cantilever arm assembly, a main spring assembly and a force-compensation mechanism. The arm assembly has a first end pivotally mounted to the base for angular displacement of the arm assembly in a substantially vertical plane between a storage position and an extended position. It also has a second end receiving a wheel chock. The main spring assembly extends between the arm assembly and the base. The force-compensation mechanism includes a lever pivotally mounted to the base for angular displacement in a plane that is substantially parallel to that of the arm assembly.
