Buying Guide: Key Purchase Considerations
When selecting an electric tarp system for a dump trailer, consider these factors to ensure optimal performance and value:
- Trailer size and capacity: Match the system’s capacity to your dump body length (up to 28–40 feet in these options) and whether a 24-foot or 28-foot trailer is common in your operation.
- Gear ratio and torque: Higher gear ratios (e.g., 90:1) generally deliver more pulling power for larger tarps and heavier loads, but may require more motor current. Balance torque with electrical capacity and wiring length.
- Shaft diameter and mounting: Verify shaft size (often 3/4″ x 4″ or 0.75″ x 3″) and the hole positions to align with your roller axles and mounting pattern (5-bolt patterns are common).
- Material and build: Aluminum arms reduce weight and corrosion; steel components can add strength but heavier and potentially prone to rust without proper coating.
- Weatherproofing: Look for sealed motor housings and chrome-plated or corrosion-resistant finishes to withstand moisture, dirt, and salt.
- Tarp compatibility: Some packages include the tarp; others require separate purchase. Check tarp material and size to ensure full coverage of your load.
- Wiring and installation: Ensure the kit includes wiring harnesses, battery cables, and a rotary switch for easy control. Longer runs may require heavier-gauge cable to preserve performance.
- Warranty and service: A multi-year warranty and readily available replacement parts can reduce downtime in busy fleets.
- Maintenance: Stainless and aluminum components tend to require less maintenance; plan for periodic inspection of shafts, gears, and electrical connections.
