1.1
Installing the Hitch Mounted Base
Position the hitch mounted crane base on firm ground such that the crane is
level. An uneven base may cause the boom to rotate in the direction the mast
is leaning.
Attach the hitch mounted crane base only to a 2 inch x 2 inch Class III or
better receiver hitch. The receiver hitch must be properly installed by a
qualified service technician.
Use the equipment in a clear location that is away from oncoming traffic or
other hazards.
Do not use the hitch mount crane base with lightweight or otherwise unstable
vehicles that may move during operation.
1.1.1
STUDY PARTS DRAWINGS to understand how the hitch mounted base is
assembled. See page 8.
1.1.2
LOCATE THE EQUIPMENT in an area clear of traffic and obstacles that
could interfere with operation. Set the vehicle’s parking brake.
1.1.3
ASSEMBLE THE BASE for the crane to be located directly behind the
vehicle. See Figure 1. Skip to section 1.1.4 if you want the crane positioned
to the left or right of the vehicle.
a
INSERT THE BASE PIPE assembly into the receiver hitch. Secure in place
with the provided 5/8” hitch pin.
b
REMOVE THE CLEVIS PINS to spread the support legs. Reinstall the
clevis pins to secure this position.
c
REMOVE THE CLEVIS PINS to extend the support legs. There are various
support leg height positions to accommodate different truck sizes and uneven
ground. Reinstall the clevis pins to secure the support legs at the desired
height. Make sure the base is level. The support legs should be able to
extend if necessary during operation.
Important!
• Inspect the hitch mounted base
during assembly. This will give
you a record of the condition of
the base with which to compare
future inspections.
• Save all packaging that the base
was shipped in, to re-use if you
need to repackage the base.
• Contact the factory immediately
if any parts are missing or dam-
aged.
