EQUIPMENT FAMILIARIZATION
All members of the crew should become familiar with the
location and operation of controls, the correct operating
procedure, the maximum lifting capacities, and the safety
precautions applicable to the unit before operating. This
crane is a complex piece of equipment and can be
overloaded in many ways. Carefully follow the operating
procedures outlined below and in the instructional pages of
the load rating chart at the operator’s station.
Equipment Checks
Perform the following checks prior to placing the unit in
operation:
• Inspect for any unusual conditions such as pools of
hydraulic fluid or lubricating oil under the chassis, any
outrigger which may have crept down or up and any
signs of damage or improper maintenance.
• Check that the tires are inflated to the proper pressure.
• Check the level of the hydraulic reservoir.
• Check the operation of the “stop” and horn circuits.
• Check for missing and loose bolts, pins, and ring
retainers.
• Check for damaged structural members and welds.
• Check all rope guides and cable keepers.
• Check all sheaves for free turning.
• Check the loadline cable for kinks, broken strands or
other damage in accordance with instructions in the
Lubrication and Maintenance Sections.
• Check to see that the hydraulic hoses and fittings are in
good condition and show no signs of leaking. The hoses
should be free from cuts and abrasions and there should
be no evidence of binding. Any damage or leakage
should be repaired immediately.
• Check HCA, anti-two-block system and jib load limiting
device for proper operation.
NOTE: Consult truck manufacturer’s manual for vehicle
checks.
Pre-Operation Inspection and Calibration
Verification
1. Check the electrical wiring connecting the various parts
of the system for physical damage.
2. Check the anti-two-block switches and weights for free
movement.
DANGER
The following tests shall be performed with care to
prevent damage to the machine or injury to personnel.
Proper functioning of the system requires successful
completion of these tests before operating the machine..
