What makes the Magnum tarp system, an Extreme Duty tarp system?

  • The 3/4″ solid steel elbow withstands more abuse and shock loads while offering greater container adjustability than the competition.
  • The low-profile pivot assembly maintains the arms and pivot below the container floor, unlike the ‘tombstone’ style tarping systems.
  • All pivot points feature self-lubricating bushings, eliminating the need for bi-weekly applications of grit-attracting grease.
  • The upper arms are equipped with deflectors to prevent damage from compactors, bowed containers, and operator errors.
  • Matched displacement lifting cylinders keep the arms aligned without the need for problematic valves that degrade and require replacement.

Upper Arms with Deflectors and 3/4” Solid Steel Elbows

  • More durable, absorbing more abuse and offering greater adjustability compared to competitors.
  • Capable of easily covering containers of 20, 30, 40, and up to 24′ 50-yard sizes, with the roller sitting on the container’s rear.
  • Upper arms remain operational even if bent or damaged, unlike telescoping arm systems.
  • Arm deflectors strengthen the arms, enabling them to deflect off compactor hinges, bowed containers, and driver errors.

Pivot Assembly with Matched Displacement Cylinders

  • The lower arm and main pivot assembly are completely below the container floor, contrasting with “tombstone” style tarpers.
  • Matched displacement lifting cylinders eliminate the need for problematic valves to synchronize the arms.
  • The enclosed pivot assembly enhances cylinder longevity by protecting it.
  • Free from exposed gears, preventing jamming or debris accumulation.

The Total Tarping Package

  • Provides total load containment for 20 to 24′ 50 yard containers.
  • The tarp roller and/or stabilizer bar are designed to sit on the container’s rear, not extending beyond it.
  • A stronger design efficiently distributes tarping loads.
  • Offers a significantly lower cost of ownership compared to imported, tombstone-style tarp systems.
