Overview notes: The motors listed here feature universal mounting options, corrosion-resistant housings, and sealed worm gears designed for outdoor, weather-prone jobs. If you operate dumps with lengths from 28 to 40 feet, gear ratios from 50:1 to 90:1 provide different balance between speed and torque. The following sections detail five representative models, with specifications drawn from their listed features to help you compare suitability for your fleet.
ALL TRUCK PRODUCTS 600W/50:1 Dump Truck Motor
The 600W/50:1 model is designed for universal fit with dump bodies up to 28 feet and works with most electric tarp systems. It features a 0.75-inch output shaft with holes drilled at 1 inch and 2 inches to align with common tarp roller axles, enabling flexible mounting options. The chrome cover adds a durable, corrosion-resistant exterior, while the 50:1 gear ratio provides a reliable balance of torque and speed for standard loads. This unit replaces multiple brands, including Roll Rite and US Tarp, making it a versatile choice for mixed fleets.
Key considerations:
- Mounting compatibility across common 3- to 5-bolt patterns.
- Moderate torque suitable for typical dump loads and weather conditions.
- Chromed housing for outdoor durability and easier maintenance.
ALL TRUCK PRODUCTS 1200W/90:1 Dump Truck Motor
This high-torque option uses a 90:1 gear ratio and 1200 watts of power, delivering strong performance for larger dump bodies up to 40 feet. It supports a universal 3/4″ x 4″ shaft with two mounting holes, and a 5-bolt mounting pattern for compatibility with many existing tarp systems. Rated for 12 VDC operation, it offers 2 horsepower and a sealing design to resist the elements. It’s described as one of the strongest tarp motors on the market, with a reversible gear motor for added versatility.
Key considerations:
- Higher torque suitable for longer dumps and heavier loads.
- Reversing motor capability can aid in rapid setup and retrieval.
- Consider electrical capacity (12 VDC, 40 A) when retrofitting older trucks.
Solarhome 60:1 Dump Truck Roll Tarp Motor
Solarhome’s 60:1 gear motor provides a balanced option for mid-length dumps, featuring a chrome cover and mounting hardware. It is designed to fit universal mounting patterns, with a 3/4″ shaft that aligns with standard canopies. The 600-watt rating ensures reasonable performance for typical weather and load conditions, while the chrome housing provides a durable, weather-resistant exterior. This motor is suitable for fleets seeking straightforward installation and reliable, steady operation across common dump sizes.
Key considerations:
- Solid mid-range gear ratio for everyday tasks.
- Universal mounting supports quick swaps across dump bodies.
- Chrome cover helps resist corrosion in outdoor environments.
FHRHRY 600W 60:1 Dump Truck Tarp Motor
The 600W, 60:1 model emphasizes rugged durability with a chrome housing and 3/4- inch shaft. It supports dump bodies up to 28 feet and uses a 60:1 gear ratio for strong torque at moderate speeds. The motor is designed to withstand harsh operating conditions, including rain and off-road terrain, with sealed components to minimize damage from dust and debris. This makes it a reliable option for fleets that require consistent performance in challenging environments without frequent maintenance.
Key considerations:
- Durability features for rugged operational settings.
- Compatibility with multiple mounting patterns and shaft configurations.
- Adequate torque to handle common tarp deployments on mid-sized dumps.
Carolina Tarps Tarp Motor 1.5HP 50:1
This 1.5HP motor delivers strong performance with a 50:1 gear ratio, making it a robust choice for heavier tarp deployments on longer dump bodies (up to 28 feet). It uses a 3/4″ output shaft and a 5-bolt mounting pattern to fit most electric tarp systems. With a 44 NM operating torque and reversible action, this unit supports quick cover and uncover operations while maintaining reliable control under load. Its universal fit is designed to streamline upgrades across mixed fleets.
Key considerations:
- Higher horsepower option within the 50:1 family for heavier loads.
- Reversible action enables fast tarp operation in either direction.
- 5-bolt mounting pattern improves compatibility with a broad range of tarp systems.
Buying Guide: Key Purchase Considerations
When selecting a tarp motor for a dump truck, consider the following perspectives to ensure you choose the right fit for your operation:
- Truck length and tarp system compatibility: Match gear ratio and shaft size to your dump body length and existing roller patterns. Longer dumps often benefit from higher gear reductions (60:1 to 90:1) for torque, while shorter setups can favor 50:1 for quicker cover times.
- Power and electrical requirements: Motors range from 600W to 1500W and operate on 12V DC. Verify your vehicle’s electrical capacity and wiring harness compatibility to avoid voltage drop or overheating during long shifts.
- Mounting pattern versatility: Look for a universal fit with multiple bolt patterns (3-, 4-, or 5-bolt) and a standard shaft size (commonly 3/4″ or 0.75″). This reduces the need for custom adapters and simplifies replacements.
- Durability and weather resistance: Outdoor use demands corrosion-resistant housings, sealed worm gears, and rugged bearings. Chrome or painted housings help resist rust and wear from road salt, moisture, and debris.
- Maintenance and warranty: A 3-year warranty, as seen with several of these models, provides assurance against manufacturing defects. Consider ease of service and parts availability in your region.
- Weight and mounting space: Ensure the motor’s dimensions fit within the available space on your dump body and do not obstruct other components or hinge operations.
- Reversibility and control: Reversible gear motors enable easier tarping in tight spots and facilitate quicker return to driving position after unloading.
- Noise and smoothness: Premium gear machines with sealed gears and precise machining offer quieter operation and longer life under frequent cycling.
Bottom-line guidance: If you operate mid- to large-sized dump beds (28–40 feet) and require strong torque with universal mounting, the 60:1 and 90:1 options from trusted brands provide the best balance of power, durability, and compatibility. For fleets prioritizing rapid cover time on shorter dumps, a 50:1 motor with solid mounting flexibility remains a reliable choice. Always verify shaft size, bolt pattern, and electrical compatibility before purchase to ensure a smooth upgrade or replacement.
