basic safety rules, found in Section 1, Introduction
of this manual, before performing any operation or
maintenance procedures.
For additional engine maintenance guidelines, see
the engine manual furnished with this crane.
Inspections
Inspect the Anti-Double Blocking System
Test the anti-double block system daily before beginning
operation to make sure it is functioning properly.
Raise the drop block until it touches the anti-double blocking
bracket under the boom head. An alarm should sound and
the raising of the hoist block should stop.
Lower the hoist block and the alarm should stop.
If there is a malfunction in the system, DO NOT operate the
crane. Have the malfunction corrected.
Inspect the Wire Rope
Each day before beginning operation, visually inspect the
wire rope for damage. See the 50 Hour Scheduled
Maintenance in Wire Rope and Sheave Inspection, for
examples of damage that can be visually inspected for. If any
damage is found, do not operate the crane. The wire rope
must be changed out for a new rope before operation can
resume.
Inspect Reeving, Clamps and Connections
Each day before beginning operation, inspect for correct
reeving of the boom and drop block.
Inspect the terminal ends of the wire rope for damaged parts,
loose clamps or wrong installation.
Do not operate the crane if any of the above is found. Only
after correcting the problem should the crane be put back in
service.
Inspect the Lifting Hook
Daily before beginning operation, inspect the lifting hook for
damage; cracks, deformation, loose retaining hardware, etc.
If any damage is found, DO NOT operate the crane until the
damage is repaired.
Inspect All Safety Devices
DAILY BEFORE BEGINNING OPERATION, CHECK ALL
SAFETY devices for proper operation. Examples of safety
devices include, backup alarm, horn, and beacon light.
If any are found to be malfunctioning, correct the problem
before placing the crane in service.
Check Controls Operation
Each control should be checked for proper operation after
the above inspections have been completed. Do not place
the crane in service if any control is not functioning properly.
Component/System Checks
Check Fuel Level
Check the fuel supply daily before operation. Turn the
ignition key to the ON position and view the fuel gauge on the
instrument panel. If necessary, fill the tank with
recommended fuel.
Engine fuel is flammable and can cause a fire and/or
explosion. Avoid personal injury or death by keeping sparks,
open flames, and smoking materials away from the crane
and fuel during refueling or fuel system servicing. Know the
location of the fire extinguishers on the job site and how to
use them.
