Claim Text:
1. A crane assembly comprising: a wheeled dolly, a telescopic crane pivotably mounted on the wheeled dolly about a crane pivot axis, the telescopic crane having a forward end, a rearward end opposite the forward end, a telescopic boom at the forward end, and a tail section at the rearward end, the tail section having a forward end and a rearward end, and a control handle mounted on the tail section intermediate the forward and rearward ends thereof, the control handle having a normally-engaged caliper brake mechanism thereon for maintaining the control handle in a fixed position until disengaged by an operator, the control handle when disengaged being rotatable about a pivot axis parallel to the crane pivot axis, wherein the brake mechanism includes: a hand grip; a cable operated by the hand grip for releasing the brake mechanism and allowing the control handle to be rotated; a fixed rotor; a first brake pad and second brake pad spaced from the first brake pad with the rotor received therebetween, the first brake pad being axially movable relative to the rotor and the second brake pad being semi-fixed; a lever rotatable between forward and rearward positions in response to operation of the cable to move the outer brake pad relative to the rotor; a rod free-floating between the lever and the outer brake pad, the rod being actuated by rotation of the lever to move the first brake pad axially relative to the rotor; and a spring normally biased in an extended position to lock the position of the control handle and having forward and rearward ends, the forward end being rotatably attached to the lever and the rearward end being rotatably coupled to the control handle.
