DLM has been manufacturing loading dock levelers in the USA since 1961.  DLM continues to provide innovative ways to improve productivity and safety at the loading dock through their leveler's superior structural design. These dock levelers can be activated automatically or mechanically and are available as pit-style or edge-of-dock storing . Each leveler type comes in a variety of sizes and capacities to meet any loading dock requirements.

Hydraulic Dock Leveler

Hydraulic Dock Levelers

Hydraulic dock levelers are push-button activated and have the highest capacity available. They utilize fully powered raise and lip extension functions with hydraulic cylinders and individual or multi-unit hydraulic pump and motor stations.  They’re also the safest loading dock choice, as these levelers contain in-line velocity fuses to prevent free fall in a truck pull-out situation. 

Air Powered Leveler

Air-Powered Dock Levelers

Air-powered dock levelers are an economical alternative to hydraulic levelers, but are still operated with a push-button activation for ease of use.  They have a mid-range capacity with an air bag or bellows system used to raise and lower the deck. The CentraAir uses compressed air and doesn't require any electricity in the dock pit.


Mechanical Leveler

Mechanical Dock Levelers

Mechanical dock levelers are an economical solution to basic applications, while still providing strength and durability.  These levelers use a pull chain activation to raise the deck.  The operator then simply walks the deck back down to the bed of a trailer or to a stored position. DLM's mechanical levelers are equipped with a Lip Drive positive lip extension and an extended range, hold down mechanism for extreme float conditions.

EOD Levelers

Edge-of-Dock Levelers


Edge-of-dock levelers mount directly to the dock face and provide a recommended working range of +/-3" and a maximum operating range of +/-5" above or below dock. DLM's Edge-of-Dock levelers are offered with either mechanical or hydraulic operation. These edge-of-dock's offer safe and easy operation along with proven efficiency and durability.
