MAST SAFETY RESTRAINT MECHANISM
Described herein is a safety restraint mechanism for a mast assembly. The safety restraint mechanism comprises a tension line attached to a lever and a winch mechanism such that operation of the winch mechanism translates a carriage assembly along the mast. A cam brake including an engagement profile at a first end thereon is pivotally attached to the lever at a second end. The cam brake is also pivotally attached to the carriage assembly such that the engagement profile pivots into a brake position or a free lift position relative to a tension force acting on the lever. The lever is pivotally attached to the second end and includes a kickstand. The engagement profile having a protruded portion to abut the tubes in a brake position and a relief portion to space the cam brake from the tubes in a free lift position.
