For this class of vehicles, the end dump unloads out of the rear with the box lifted high into the air. That height is exactly why arm geometry and clearance matter. A Pulltarps system has to clear a fully raised box without adding instability. Automatic systems work best for this category.
GVWR: 26,001 – 33,000+ lbs
Unload: Rear · Box Raised
Recommended System: SuperShield™ 9500E
An end dump trailer empties out of its rear by hydraulically raising the front of the box until the load slides out the back. These are the workhorse trailers of construction, demolition, agricultural, and landscaping fleets.
Class 7 Weight Limit: 26,001 – 33,000 pounds
Class 8 Weight Limit: 33,001 pounds and up

Common Uses
Three configurations rated for the length and duty cycle of an end dump. Arm geometry is spec’d to clear a fully raised box; configure for your exact length on the system page.
Automatic · Recommended
Our SuperShield comes with a heavy-duty 12-gauge steel housing, 1.3 HP electric motor, a full enclosure designed for daily-driver Class 8 dumps, and a 1-year warranty on moving parts.
Automatic
Versatile electric automatic for standard and long end dump bodies. Steel housing, sealed motor, and arms tuned to clear a raised box on uneven ground.
Automatic
The Core Automatic Tarp System is an economical, cut-to-fit electric tarping system that fits into the cab shield of most dump truck bodies. The Core System is great for applications where falling debris and loader damage is not a concern. It includes Core Diamond end plates, a 1.3 horsepower electric motor kit, and a 12V in-cab smart switch with all of the needed wires.
Final configuration depends on trailer length, tarp material (Vinyl, HD Mesh, Super HD Mesh, Asphalt Vinyl), and arm clearance for your raised-box height. Configure each system for pricing on its product page.
End dumps run both automatic and semi-automatic systems. Automatic systems are safer, since the operator never has to climb a box that’s about to lift high. Semi-automatic systems, though, are the more cost-effective call for trailers cycling fewer times per day on stable ground.
Default For End Dumps
+
The cab-switch means drivers never climb a raised box
+
~10-15 second cycle, no climbing
+
Best operator-safety + DOT compliance story
−
Higher upfront cost; requires cab wiring
Best for: Fleet trailers running 5+ cycles/day, hot-mix asphalt, regulated jurisdictions.
Budget Pick
+
Spring-assisted, no electric required
+
Lower upfront cost, simpler service
+
Still ground operated, without the need to climb the box
−
Manual pull — slower cycle, more operator effort
Best for: 1-3 cycles/day, owner-operators, stable-ground sites.

Questions buyers ask about tarping Class 7 – 8 end dump trailers. Real queries from the field.
It shouldn’t if it’s spec’d right. An end dump already sits high and narrow when the box is fully raised, so a poorly mounted tarp can shift weight at the worst moment. Pulltarps arms are engineered to clear a raised box and stow without adding load up high. The bigger stability factor is always the ground: raise on a firm, level surface, never on a slope or soft fill.
Yes, federal regulation 49 CFR § 393.100 requires secured cargo on commercial vehicles, and every U.S. state adds dump-specific rules. Hauling aggregate, asphalt, dirt, or demolition debris means you tarp it. Requirements vary state-to-state — see our state-by-state guide.
Measure your trailer length and box width, then add 12 – 18 inches in each direction for rolling and side coverage. Most end dumps run 24′ – 36′ lengths at 88″ – 90″ width. The configurator will spec the exact size once you enter your dimensions.
A trained installer typically completes an automatic end dump system in 4 – 6 hours including arm clearance setup and cab wiring. Semi-automatic installs run 2 – 3 hours. Use the installer locator to find a shop near you.
Automatic is the safer pick because the operator never climbs a box that lifts high to unload — everything happens from the cab switch. Semi-auto is a sound budget choice for trailers cycling only a few times a day on stable ground. The comparison above breaks down the trade-offs.
Pulltarps automatic systems carry a 5-year limited warranty on the housing and motor and a 1-year warranty on the tarp. Asphalt Vinyl lasts longer in hot-mix work; HD Mesh and Super HD Mesh hold up better in demolition and aggregate. Read the full warranty terms.
