Mechanical Leveler Constructor Series

The Constructor Series of the NORDOCK® Mechanical Levelers features easy release activation and is intended to be the cost effective alternative built for the toughest loading dock.

Affordable and easy-to-install

The Constructor Series is designed for the construction industry exclusively.  This series offers a high quality and easy-to-install dock leveler that is also affordable and cost effective.  In addition to capacity ratings from 25,000 – 45,000 lbs., these levelers also come with two heavy-duty dock bumpers as well as standard characteristics featuring security night locks, welded structural side guards, and ergonomic walk-down lip extension.  The pit area is easy to clean because of the open-frame design.  Finally, the exclusive “Guaranteed to Outperform” Warranty comes with these Constructor Series Levelers.

Constructed for the toughest, roughest loading dock

Advanced, superior strength is provided by this leveler’s platform structure that has continuous welds at hinge tubes and the header plate as well as a 33% dual side beam to deck weld pattern.  The frame is consguaranteedtructed of five hinge connections, at least five solid steel rear supports, and a full width rear hinge rod.  The lip and deck plates as well as the beam sections and lugs are built of at least 50,000 – 55,000 PSI yield material.


Activated by easy release

The operator releases the holdown at the back of the platform until the deck is elevated and stopped.  He then walks the platform down until the standard 16” lip extends onto the truck bed and connects 12” below and above floor level.  While the truck is loaded, the deck floats up and down.Download PDF
