BOOM LIFT TRANSPORT
The boom lift trailer includes a single axle, two-inch
ball hitch, hydraulic surge brakes, mechanical
parking brake, breakaway safety cable, safety
chains, brake lights and side marker lights. Proper
boom transport requires the proper attachment and
inspection of these components before towing. Refer
to Figure 3-9.

Figure 3-9. Trailer Hitching
Use the following procedure to hitch and tow the
boom lift.
Back the tow vehicle to the trailer. Verify that the
ball and hitch are aligned and that the trailer
hitch has proper clearance above the ball. Use
the tongue jack as needed.
CAUTION
Obtain, read and obey all recommendations set
forth by the tow vehicle manufacturer before
attempting to transport equipment. Verify that
equipment weight does not exceed the vehicle’s
towing capacity. Exceeding the tow vehicle’s
rated capacity may result in damage to tow
vehicle or boom lift.
Fasten the breakaway safety cable to the tow
vehicle.
Lift release lever and lower the hitch onto the
ball using the tongue jack. Push down the
release lever to secure the ball.
Use the tongue jack to verify secure coupling. If
using the jack will raise the bumper of the tow
vehicle 2-3 inches, the ball hitch coupling is
secure.
Release the trailer parking brake.
On the tongue jack, pull the pivot locking pin and
swivel jack 90 degrees to the travel position.
Reengage pivot locking pin.
Attach the safety chains to the tow vehicle.
Verify that the chains cross under the trailer
tongue. If necessary, cross the chains first over
then under the tow bar to prevent dragging.
CAUTION
Failure to attach safety chains properly before
towing will allow trailer tongue to drop in case of
ball hitch failure, resulting in damage to trailer
and equipment.
Connect the trailer lights to the tow vehicle
power plug.
Verify that the breakaway safety cable has
adequate slack to prevent the brakes from
dragging.
Verify the following before towing the lift. Make
adjustments as necessary.
The trailer jack and outriggers are in their travel
positions.
Boom travel latches are engaged, securing the
booms in their fully stowed positions.
All on-board equipment is secured.
The key switch is in the OFF position. Remove
the key.
The parking brake is disengaged.
The trailer tires are adequately and evenly
inflated.
Periodically check the wheel nut torque according to
manufacturer’s recommendations. Frequent torque
checks are required when a wheel is recently
installed.
Prior to towing, while the trailer wheels are elevated
for boom lift operation, inspect for loose wheels and
for wheel lug wear. If a loose wheel mounting is
suspected, remove and inspect wheel lugs for
damage. DO NOT tow a boom lift with worn or
damaged wheel components.
