Donovan® Brand HAMMER™ II Tarping Systems


With the Hammer™ II, you get one-size-fits-all styling for dump bodies up to 23 feet. Strong 1 1/2-inch diameter round “easy-off” pivot arms and flat coil torsion springs provide smooth, powerful operation. The GL model has a ground-level manual crank while the standard Hammer™ is powered by the Durabuilt™ 12V direct-drive motor with rotary switch. Optional upgrades include 40-amp Durabuilt™ rocker switch kit with solenoid, wind deflectors, pivot arm rests and spring trap and tarp trap hold-downs.


When pricing your Hammer™ system, you will need to order your choice of tarp and add that to the price. Choose from heavy-duty mesh, multicolored PVC mesh, 18-oz. vinyl or asphalt lumite. Asphalt lumite is water resistant and not PVC coated, so it’s able to handle much higher heat levels than vinyl. In addition to lumite, other asphalt-friendly selections are also available, including RFL, urethane-coated airbag, 22-oz. vinyl and doloprene. More tarp options can be selected, such as non-standard colors, side flaps, reinforced pockets or hems, webbing, boxed corners, stenciling, grommets and D-rings. Approximate shipping weight: 220 lbs.
