Vehicular Operation
The Hydraulic Crane is capable of both on-road and limited off-road travel. The kind of
travel undertaken determines how the carrier is operated.
Before moving the crane, either around the work site or between sites, carefully consider
the terrain type, road conditions, and any hazards likely to be encountered en route. Think
the move through in advance and carry it out safely.
CARRIER BREAK-IN Refer to special break in requirements for new cranes on page 287.
PRE-MOVE CHECK LISTBefore moving the crane to and from job sites, make sure the
following safety checks have been made:
1.
Stow the boom in the boom rack.
2.
Lock the upper structure swing brake and engage the mechanical swing lock.
3. Secure hoist block to the bumper loop. If this is impractical, pull the anti-two block
system counterweight up to within approximately 1” of the load sheaves, or until block
lightly contacts boom head.
Use the anti two block override switch to temporarily bypass the two block system
disconnects. Failure to pull the hook block up to the head when traveling, or to secure it to
the bumper ring, will result in excessive swinging of the hook block and possible damage
to machine.
Continuing to pull the block up after contact has been made may result in
damage to the boom head and sheaves.
4. Verify that the hydraulic outrigger beams are fully retracted and secured with retaining
pins.
5. Check tires for proper inflation pressure.
6.
Adjust the seat and mirrors for clear vision.
7. Disengage the main hydraulic pump drive. Never travel with the main hydraulic pumps
engaged.
8. Check the counterweight and removable slabs (if so equipped) to ensure that they are
properly secured for roading and that the weight is balanced so as not to over load
axles or tires (see the maximums on page 2 of the lift capacity chart).
MOVING THE MACHINE:The general procedure for moving a machine is as follows:
1. Be seated in the driver’s seat with the seat belt fastened low and snug.
2. Thoroughly review the shift pattern of the transmission.
3. Start the engine, following the procedure in the topic “Starting the Engine.”
4. Allow air pressure buildup.
5. Make sure the boom is stowed in the boom rack.
