BOOM RESTS
Before the mounting of a crane is complete, a boom rest
must be installed. A rest must be supplied for transport to
reduce vibratory stress on the crane and truck and protect
rotation system from transient damage.
Below are shown configurations to meet application of the
user. All of these configurations are available at your
National Crane distributor.
The loadline shall be hooked to some point on the bed, truck
frame, etc. to secure the hook weight during transport. Install
tie down point low enough to allow room for anti-two-block
weight. Do not shorten chain.
The boom rest should be positioned to support the 1st
section boom. Be careful to avoid contacting the boom at or
near the end where the retract cables are located. Contact
with these cables will result in costly repairs.
The boom rest saddle provided is designed to support the
1st section boom. It will be necessary to modify the saddle to
make it narrower and reposition the support cushions under
the boom side plates if the boom is extended to reach the
boom rest.
