Why the M Series

Three reasons facilities managers
specify this Pioneer product

DOORTEC installs the complete Pioneer dock equipment lineup throughout Oklahoma City, Tulsa, and the OKC metro.

Structural “C” Channel — Not Sheet Metal

Every M Series structural member is solid steel “C” channel — not formed sheet metal shapes. Each beam fully welded to a full-width header plate. It’s a construction difference that shows up in service life.

Hydra-Lip Automatic Extension

The lip slows on descent to allow safe walk-down onto the truck bed — then extends automatically. No manual lip placement. Consistent, repeatable, every cycle.

No Moving Parts in the Spring System

Direct extension spring design eliminates the rollers, cams, and lanyards that are the common failure points on competitive mechanical levelers. Fewer parts means fewer service calls.

Structural “C” Channel Construction

Solid steel “C” channel — no formed sheet metal shapes. Each beam fully welded to a full-width header plate at the front of the leveler.

Hydra-Lip Automatic Lip Extension

Lip slows on descent, allowing walk-down onto truck bed. Extends automatically — no manual operation required. Positive lip extension every cycle.

Direct Extension Spring — No Moving Parts

No rollers, cams, or lanyards in the spring system. Simple, precise adjustment via an adjustment nut at the front of the leveler — safe, easy access.

Pull-Chain Activation

Pull-chain conveniently located for easy deck and lip activation. Spring-assisted operation — single-person raise.

Safety Features

Positive hold-down allows up/down float while servicing truck. Lip keepers serve as night locks and cross-traffic support. Maintenance struts standard. Automatic below-dock safety legs.

Side-to-Side Compensation

Deck tilts maximum 4” side-to-side to compensate for unlevel trucks — reducing strain on dock door seals and leveler frame.
