The 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.
