Travel Precautions
NOTE: The following paragraphs list several important
travel precautions which must be taken into
consideration when traveling with the crane in the
trailing boom configuration.
• Use of the trailing boom feature may require reducing
travel speeds. Adjust travel speed to suit driving
conditions (i.e. traffic, highway, weather).
• The crane boom and trailer combination requires a wide
turning radius. When turning during driving, allow extra
space on both the left and right sides of the carrier.
• The superstructure will rotate and stick out past the side
of the carrier that is opposite the direction the carrier is
being steered/turned when traveling.
• Reduce travel speed to avoid undesired weight transfer
between the carrier and the boom trailer at abrupt crests
and undulating terrain.
Returning to Normal Crane Operation
1. Position the crane and trailing boom carrier on a firm
level surface with the boom carrier directly behind the
crane.
2. Block the wheels and apply the parking brakes.
3. Turn the lift cylinder float valves clockwise to the
normally closed position.
4. Pull out the knobs on the swing brakes to set for normal
brake operation and padlock.
5. Turn air locking pin valve knob to the RETRACT
position. Visually check locking pins to ensure they are
disengaged.
6. Raise the boom from the trailing boom carrier.
7. Disconnect all air and electrical lines from the rear of the
crane.
Parking the Trailing Boom Carrier

carrier.
1. Apply the emergency/parking brake in the carrier cab.
Refer to Trailing Boom Trailer Emergency Brake Control
