ALL TRUCK PRODUCTS 600W/50:1 Tarp Motor
Best for moderate-size dump bodies and rapid deployment, this motor uses a 0.75″ x 3″ output shaft with two drilled holes to fit common tarp rollers. It’s designed as a universal replacement for several major brands and fits dump bodies up to 28 feet. The 50:1 gear ratio balances speed and torque for steady tarp operation. Ideal for fleets seeking a cost-effective, widely compatible option. A potential limitation is that it may require matching hardware to your specific roller system.
ALL TRUCK PRODUCTS 1200W/90:1 Tarp Motor
Best for larger dump bodies, this motor delivers 1200 watts with a 90:1 gear ratio and a 12 V DC system. It provides a strong torque suitable for longer or heavier tarps and has a 5-bolt mounting pattern for flexible installation on 3- or 4-bolt setups. It’s a strong premium option for fleets prioritizing high power and reliability, though it may require more robust mounting hardware on smaller trailers.
Solarhome 90:1 12V 0.8HP Dump Truck Roll Tarp Motor
Best for quick payloads on mid-size jobs, this motor uses a 90:1 gear ratio with a chrome cover and a universal 3/4″ shaft. It supports universal mounting with multiple bolt patterns. This option suits operators needing a balance of torque and mounting flexibility in varied weather, though it may be less powerful than higher-wattery models for very long tarps or heavy loads.
Dump Truck Roll Tarp Motor with Chrome Cover, 12V 2.0 HP
Best for heavy-duty, tall, or longer tarps, this 12V, 2.0 horsepower motor features a 90:1 gear ratio with a sealed, anodized die-cast aluminum body for durability. It includes a chrome cover and universal shaft fit. Choose this if you regularly haul larger loads or operate in tough environments. A limitation is that higher power often requires a robust mounting system and adequate electrical supply.
Buyers Products 5541095 600W Tarp Gear Motor
Best for long-term durability in harsh environments, this 12V motor uses a bronze gear for extended life and features a weatherproof chrome cover. It’s designed for consistent torque and speed to ensure fast, reliable tarp deployment and retraction. It’s a solid pick for fleets needing durable performance in wet, muddy, or challenging conditions. A potential drawback is that bronze gears may have different wear characteristics compared to newer metal alloys in some contexts.
Buying Guide
What mounting pattern does your tarp system require?
- Check for bolt patterns: 3-bolt, 4-bolt, or 5-bolt mounting options are common. Choose a motor with a matching pattern or compatible adapters.
- Confirm shaft size: Most tarp rollers use 3/4″ or similar shafts; ensure the motor’s output shaft matches your roller’s bore.
What torque and gear ratio do you need?
- Higher gear ratios (e.g., 90:1) increase torque, helpful for longer tarps and heavier loads but may reduce speed.
- Lower ratios (e.g., 50:1) offer faster retraction but less force. Match to your tarp length and typical load.
What environment will it operate in?
- Look for weatherproof housings and corrosion-resistant materials for trucks exposed to rain, mud, and road salt.
- Consider sealed designs and chrome covers for added protection against debris.
Voltage and power considerations
- Most dump tarp motors run on 12V DC systems. Confirm your vehicle’s electrical capacity to handle the load without frequent battery drain.
- Power (watts) relates to torque and speed; higher wattage generally means stronger performance but greater electrical demand.
Installation and maintenance
- Choose motors with universal mounting or broad compatibility if you plan to replace existing units.
- Inspect the drive system for heat dissipation; aluminum or die-cast housings can help reduce heat buildup during operation.
FAQ
- Q: What is the best tarp motor for a 28-foot dump trailer? A: A motor with a 50:1 or 60:1 gear ratio and universal mounting is typically suitable for up to about 28 feet; refer to the product’s mounting pattern and torque specs.
- Q: Do all tarp motors require a chrome cover? A: Chrome covers are common for protection, but not always mandatory. They help resist corrosion and debris in harsh environments.
- Q: Can I mix different brands of tarp motors on the same trailer? A: It is possible but not ideal. Uniform mounting, electrical compatibility, and synchronized operation are easier with a single-brand setup.
- Q: How do I know if a motor is powerful enough for my tarp length? A: Longer tarps require higher torque. Check the gear ratio and wattage; higher torque generally indicates better performance with longer loads.
- Q: Are bronze gears more durable than steel in tarp motors? A: Bronze gears provide good durability and wear resistance for continuous operation; the choice depends on design and maintenance preferences.
