FRONT FRAME
Set the reach and connect the front support (1) to the front
beam (2) with two 3/4" dia. locking pins (3) onto the ‘U’ shaped
Top Ledger of the front support, through aligned holes* on the
frame and beam. Be sure to lock the pins with the hair pins (4)
provided. When attaching the front support (1) ensure you do
not exceed the maximum extension of the front beam (2)
based on your load weight calculations.
*Note: The front support (1) has three holes in total,
always face the side with two holes toward the front of

configuration being used. The top is used when
the beam configuration is for inclined position
and the bottom used for the
horizontal position.

support and align the holes and connect using a 3/4” locking
pin (3) and secure with the hair pin (4).

plates under the two vertical extensions (10) of the
inclined front support, to unload the wheels.
