Shur-Trak HD Motor | Donovan, Shur-Co Tarping Systems

Heavy-Duty Direct Drive Power for Roll-Off Tarp Systems

The Shur-Trak HD Motor (SKU: 20-1122442) is a premium, high-torque direct-drive motor engineered specifically for Donovan and Shur-Co automated tarping systems. Designed to handle the extreme demands of the waste management and heavy construction industries, this 12-volt DC motor provides the reliable, consistent power needed to deploy and retract heavy Mega Mesh and solid vinyl tarps over 40-yard roll-off containers and large transfer trailers. When your fleet's productivity depends on fast, reliable load securement, the Shur-Trak HD delivers the torque required to overcome wind resistance and heavy material drag.

Unlike standard duty motors that can burn out under the strain of continuous commercial use, the Shur-Trak HD features a sealed, weather-resistant housing that protects internal components from moisture, road salt, and corrosive landfill environments. Its direct-drive configuration eliminates the need for complex chain or belt reductions, reducing maintenance requirements and ensuring immediate power transfer to the roller axle. Whether you are replacing a failed motor or upgrading an existing truck tarp system, this OEM replacement guarantees perfect compatibility and restored performance.

Engineered for Donovan & Shur-Co Systems

This motor is an authentic OEM component manufactured to the exact specifications required for Shur-Co and Donovan automated systems. It is the direct replacement for the power unit used in the popular Shur-Trak II system, as well as compatible front-to-back cable systems. Using genuine replacement parts ensures that the motor's mounting flange, output shaft, and electrical connections align perfectly with your existing hardware, eliminating the need for custom fabrication or mounting modifications during installation.

For fleet managers and owner-operators, standardizing on genuine Shur-Trak HD motors means fewer electrical failures, faster deployment times, and reduced downtime. Pair this motor with a high-quality roll-off truck tarp to ensure your automated system operates at peak efficiency, keeping your drivers safe inside the cab while complying with all state and federal load securement regulations.

Installation and Maintenance

Installing the Shur-Trak HD Motor is a straightforward process for mechanics familiar with 12-volt commercial vehicle electrical systems. The motor mounts directly to the system's existing drive assembly flange. We strongly recommend inspecting your system's wiring harness, contactor, and rocker switch during installation; a failing contactor or corroded wiring can cause voltage drops that will prematurely damage a new motor. Always ensure the system is properly fused or equipped with a functional manual-reset circuit breaker to protect the motor from power surges or dead-stall conditions caused by frozen tarps.

Frequently Asked Questions

Is this motor compatible with 24-volt electrical systems?

No. The Shur-Trak HD Motor (1122442) is engineered exclusively for standard 12-volt DC commercial vehicle electrical systems. Operating this motor on a 24-volt system will cause immediate catastrophic failure and void the manufacturer warranty.

Does the motor include the mounting hardware and cover?

This listing is for the replacement motor unit only. Chrome or aluminum motor covers, mounting bolts, wiring harnesses, and electrical contactors are sold separately. You can typically reuse your existing mounting hardware and cover if they are in good condition.

How do I know if my old motor has failed or if it is an electrical issue?

Before replacing the motor, use a multimeter to verify that a full 12 volts is reaching the motor terminals when the switch is engaged. If voltage is present but the motor does not turn, or if it turns very slowly and draws excessive amperage, the motor has likely failed. If no voltage is present at the motor, check your circuit breaker, rocker switch, and contactor solenoid first.

Can this motor pull a heavy asphalt or vinyl tarp?

Yes. The Shur-Trak HD is a high-torque unit specifically designed to handle the heavy drag of solid vinyl tarps and asphalt covers, even in cold weather conditions where the fabric becomes stiff. However, always ensure your tarp is free of heavy ice or debris accumulation before operating the system to prevent dead-stalling the motor.

Expert Application Guide: Choosing the Right Motor for Your System

As an industry standard component used across thousands of commercial waste hauling and construction fleets, the Shur-Trak HD Motor is designed for demanding use cases where reliability is non-negotiable. Fleet managers and owner-operators who have tested both standard-duty and heavy-duty motors consistently report that the HD unit outperforms in three critical areas: cold-weather torque retention, resistance to moisture ingress, and long-term bearing durability under continuous daily cycling.

When evaluating a replacement motor for your application, consider the following expert criteria. First, verify your system's roller tube diameter and output shaft size — the Shur-Trak HD uses a standard shaft specification compatible with Shur-Co and Donovan roller assemblies. Second, assess your tarp weight: if you are running a heavy 18 oz. or 22 oz. vinyl tarp, the HD motor's high-torque output is the appropriate specification. Standard-duty motors are designed for lighter mesh tarps and may overheat or fail prematurely when tasked with pulling heavy solid vinyl loads. Third, inspect your vehicle's electrical system — a motor rated at 12V DC requires a healthy battery and clean ground connections. Voltage drops below 11V under load will cause sluggish operation and accelerated motor wear.
