Lowest profile arms in the industry

  • Arms below and in front of the majority of all containers and compactors eliminating the 2 out of 3 things that damage a tarp system.
  • Lightest weight, fully adjustable, fully hydraulic tarp system with an installed weight of 850 pounds. Get back the weight capacity you lost with the latest round of emissions controls by switching to a Diablo
  • Our patented elbow upper arms enable the operator to place the roller on the rear of the container (10 to 40 cubic yard containers for lengths from 16’ to 22’) or on the rails of the hoist. This minimizes arm damage, maximizes your tarp life while preventing debris from blowing out the container.
