Collapsible Wheel Risers

Improve Loading Dock Flexibility

Collapsible Wheel Riser will service different styles of trailers at loading docks utilizing its two-position ramps. Designed to handle standard over the road trailers and custom vehicle heights to eliminate the need for additional dedicated dock positions and static
wheel risers.

Improve Your Loading Dock Operations

The Collapsible Wheel Riser will allow you to service specialty trailers such as automotive drop decks or other low style trailers and will make the unloading of standard 48” dock you will slightly raise the floor of the trailer reducing product damage from servicing trailers below dock level, minimize the effects of “stump-out” by mechanical levelers and gain full width access to trailer bed above dock level.

The Collapsible Wheel Riser ultimately improves productivity and safety.

The Adjustable Wheel Riser is a electro-mechanical product that is hydraulically
positioned between two separate heights that are designed to match the
customers loading dock operation. The raised position will handle trailers with
lower than 48” bed heights. The collapsed position of the wheel riser is designed
to allow standard 48” floor height trailers to back in and position them optimally
2-3” above finish floor level. The structure consists of two separate ramp and
deck structures which rotate towards the dock face, while elevating the deck to
the raised position.

Standard Operation

The Adjustable Wheel Riser is positioned prior to the trailer backing into the
dock position either raised or collapsed. The trailer backs onto the platform for
loading/unloading. If raised, the riser deck will be in an elevated over-toggle
position, resting against the dock face. This triangulation between the riser deck,
dock face and approach holds the trailer securely in the raised position. Once a
trailer is in place, the hydraulic system is designed that it cannot be repositioned
due to the additional trailer weight on the decks. Prior to the next operation, if
the dock attendant needs to alter the position, a simple momentary press of the
“Raise” or “Lower” button energizes the hydraulic powerunit, and the deck will
travel to the new position.

Installation

There are two deck and ramp assemblies that ship separately along with spacer tubes that must be field welded together for structural integrity. The sub-frame is located against the building wall and centered on the tire paths for the types of trailers to be serviced.

Installation now consists of shimming under the sub-frame of the riser to allow free travel of the support legs from position to position. The sub-frame is bolted to the concrete approach using ¾ “ x 6” long concrete anchors. After mechanical installation, the hoses are installed to the lifting cylinders and routed inside the building to the hydraulic powerunit. The
powerunit is then wired to the control box along with the raised and collapsed sensors.
Multiple voltages are available to suit the application.

Warranty

One-year on all parts and labor from date of shipment. All warranties are subject
to standard limitations on liability.
