Abstract
Aspects of the disclosure relate to counterbalance systems for catwalk systems, and related methods. A counterbalance system pulls a trough of a catwalk system while actuating the catwalk system. A catwalk system includes a chassis, a main arm pivotably coupled to the chassis, a trough pivotably coupled to the chassis and having one or more rollers, a V-door ramp pivotably coupled to the chassis, and a counterbalance system coupled to the trough at a coupling point. The counterbalance system includes a first sheave suspended from the V-door ramp, a second sheave suspended from the first sheave, and a counterbalance rope wound at least partially about the first sheave and the second sheave. A first end of the counterbalance rope is coupled to the trough at the coupling point.
