Mechanical Pit Leveler

M68R & M78R

Fast, safe install with height adjusters operated while standing on building floor-no need for installer to be under leveler and no shimming/welding needed in rear of pit
Adjusters quickly position the dock level with the building floor
Improved safety — the installer is never under the leveler
Levelers ship with four steel fork loops bolted to the deck, which improves stability when lifting from a truck. The loops help with forklift placement into a pit from inside or outside the building, and helps to minimize levelers sliding while stacked on top of each other
Cut outs identify weld points to the curb angle for faster installation
Lifter arm is mounted to the rear of the frame instead of sitting on pit floor. No need to shim or weld under the lifter arm

Durable Design and Finish

Base frame is open all the way to the rear of the pit for easy access with no cross beams or places to trap debris
C-channel beams create a strong deck structure and allows moisture to dry
Deck design eliminates the transition angle which is a frequent repair on many levelers
Deck hinge is fully supported across the entire width of the deck to enhance long term durability
Durable textured powder coat finish
Compliant with ANSI MH30.1-2022

Smooth Building-To-Truck Transition

Designed with an optimized beveled lip to reduce bumps and damage to cargo and material handling equipment
Reduces shocks and jolts to workers by creating a level pathway
Facilitates fast movement of material handling equipment and forklifts

Easy-to-Use and Ergonomic

Release chain for deck operation is user friendly and easy to pull
The hold down is easy to operate
Leveler is well-balanced for quick, easy articulation and automatically maintains positive lip contact with trailer movements
The snubber chain and maintenance brace are positioned at side edges allowing easy access to the pit for maintenance and cleaning

Overview
Documents

Installer Friendly

Safety Focus

Installers are never under the pit
Minimal bumps or gaps on deck/lip reduce trip hazards for workers
Proprietary powder coat formulation on deck and lip surfaces is textured to provide enhanced traction and non-slip protection even when wet

Durability, Low Maintenance, Low Downtime

Heavy duty multi-lug construction of the lip hinge. The design helps shed debris instead of trapping/grinding it between the lip/deck junction that can cause fatigue and maintenance issues. The lug construction also allows for easy lubrication of the hinge.
Deck hinge is fully supported across the entire width of the deck, which spreads the load across the width of the deck instead of concentrating the load on just a few hinge points
Durable textured powder coat provides an extremely durable finish, better corrosion protection and adhesion compared to wet paint
Complies with ANSI MH30.1-2022 that includes rigorous load testing requirements
Deck Thickness ¼ inch
Lip Thickness 5/8 inch 30/35K, ¾ inch 40/45K

Environmentally Friendly

Our powder coat process has fewer Volatile Organic Compounds (VOCs) and solvents compared to paint
Overspray is recycled which reduces waste disposal issues compared to a traditional paint process
The US Environmental Protection Agency (EPA) recommends powder coatings as a sustainable coating option

Installation and Serviceability

Open base frame creates generous space for service along the full length of the leveler, including the rear which is the most difficult area to reach for cleaning and a common collection point for debris
Leveler main springs are tightened/loosened with one adjustment point conveniently located on lift arm
Field serviceable with easy to reach adjuster for main spring
Serviceable lip and hinge pin can be removed without breaking welds
Maintenance brace is easy to reach under the leveler and is tethered so it never gets lost. Brace holds leveler up by the deck to allow lip maintenance
Leveler ships with four forklift lifting loops bolted to deck, allowing leveler to be lifted from the front or rear for easy transport and placement in the pit
