Pit Style Mechanical Dock Leveler

When size does matter, choose Poweramp’s® HM Series heavy-duty mechanical loading dock leveler.

The Poweramp HM Series is a manually operated leveler. The dock attendant simply pulls the release chain at the rear of the platform. A Cam Control Counter Balance Assembly then raises the leveler and a fully yieldable hinged lip is automatically extended at the top of the upward travel.
The attendant walks the platform down onto the trailer bed. If the trailer bed is below dock level the attendant activates a second pull chain at the front of the platform during the walk down. Operating range is 12” above and 12” below dock level. The platform is designed to compensate for canted truck beds up to 4” and remain flush with the dock floor. An automatic release feature protects the device under extreme float conditions common when “air-ride” suspension trailers are serviced.

The HM Series is designed for heavy-duty applications and has a maximum Comparative Industry Rating (CIR) of 50,000 lbs. All Poweramp Levelers are built with a durable four-sided box construction. The use of structural steel C channels or I beams create substantially more deck support than other levelers.


Dual pivoting cross traffic legs for multi position safety in the event of early departure.
Working range toe guards close off sides in the service range position.
Built in lockout/tagout maintenance inspection strut and lip support.
Lip keepers for cross traffic support and automatic night lock security against theft.


For a safer loading dock, all Poweramp levelers can be equipped with a light communication system and vehicle restraints, which help prevent unexpected trailer departure from the loading dock. A Bar-Lift Safety Barrier is also available to prevent forklift trucks from driving over the dock edge.
