Rack 'n Pinion Strong Arm System
Pioneer's RP4500SAR is an enhanced Rack & Pinion system designed for hooklift and rolloff trucks on which space is limited behind the cab. Starting with the strengthened base arm, through the Rack 'n Pinion Pivot. And on to the reinforced "C" Channel, the RP4500SAR delivers better leverage, greater control, and a longer life span. Includes telescoping lower arms, a fixed gantry w/ Rollmaster roller assembly, 3/16" A5 steel strong arms, external cylinders, and a reinforced black mesh tarp. See below for other tarp options.
The Rollmaster RP4500SAR roller assembly features Pioneer's Rack 'n' Pinion Strong Arm technology for greater control of your system's side arm movement. The rack gear's forward and backward movement is controlled by a hydraulic cylinder which works in conjunction with the pinion gear located at the base of the pivot arms. This fully hydraulic system is known for reliability and low maintenance. The technology allows for speed control and precision synchronization of the pivot arms as you raise and lower the cover to your container.
Rollmaster with Fixed Gantry
The RP4500SAR model comes with the Rollmaster roller assembly, fixed legs, roll rest for limited space behind the cab, our standard tarp and patented telescoping Low-Arms with nitrided (case hardened) external cylinders. This model is for use with 22' to 24' hooklift trucks, cable hoist trucks, trailers transporting containers of various heights and trucks where space behind the cab is limited.
Beyond the Strong Arm technology, Pioneer's RP4500SAR Rollmaster system uses a unique spring-loaded roller assembly, creating a smooth rolling action with your fabric tarp. This roller assembly is so versatile, it can be mounted to the pivot arms on models with both adjustable gantries and stationary roll rests.
