Why the SMART+™ HDH 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.

Heavier Cylinder, More Durability

The HDH uses a 4” diameter main lift cylinder where the HP uses a 3”. That single upgrade translates to measurably longer service life at high-cycle docks and with heavier trailer fleets.

Same Push-Button Simplicity

Same fully hydraulic operation as the HP — push-button raise, automatic lip extension, automatic return to stored — with the extra cylinder capacity that heavy-duty applications demand.

5-Year Structural and Cylinder Warranty

Full five years on structural members and cylinders. The HDH’s extended cylinder rating is backed by Pioneer’s strongest warranty tier — matched by DOORTEC’s own workmanship guarantee.

All specification data sourced from Pioneer Dock Equipment official documentation. Contact DOORTEC at (405) 720-7107 for sizing, capacity, and application guidance.

4” Main Lift Cylinder

The HDH’s defining upgrade — 4” diameter main cylinder with 2” diameter ram vs. the HP’s 3” cylinder. Measurably more durable at high-cycle, heavy-load dock applications.

Push-Button Operation

Fully hydraulic — single button press raises deck, extends lip, and descends onto truck bed. No pull chains. No manual lifting.

Automatic Lip Extension

Lip extends automatically at the top of the raise cycle, confirmed before descent.

Auto Return to Stored

Unit returns to cross-traffic stored position automatically when the truck departs.

Structural “C” Channel Deck

Structural channel support beams fully welded to full-width header plate. Molded bumpers, toe guards, and grease fittings on lip hinge all standard.

Safety Systems

In-line safety stop, below-dock safety legs, and molded bumpers — full complement of safety features standard on every HDH.
