Rack-N-Pinion Trailer Arm Tarping System

The Rack-N-Pinion Trailer Arm Tarping System from Pioneer uses proven rack and pinion technology to deliver smooth, controlled, and synchronized tarp movement. Designed for reliability and precision, this system provides consistent performance when covering and uncovering roll-off containers.

How the Rack-N-Pinion Trailer Arm System Works

This trailer arm tarping system uses a hydraulic cylinder to move a rack gear forward and backward. That rack gear engages a pinion gear mounted at the base of the pivot arms.

This design creates a mechanical advantage that allows for:

• Controlled speed during tarp deployment
• Precise synchronization of both trailer arms
• Smooth, repeatable operation with minimal wear

The result is a tarping system that performs consistently, even in demanding application. 

Designed for Roll-Off Trailer Applications

The Rack-N-Pinion Trailer Arm system is engineered specifically for:

• Application: Cable hoist roll-off trailers
• Container Size: Up to 32-foot containers
• Standard Tarp: Heavy-duty mesh tarp

This system is deal for operators who need dependable tarp coverage with long-term durability.
