3-50 ZCC1100H Crawler Crane
When the boom is less than 275
’6”(84 m), the centre of load hook must/should be aligned
with the centres of slewing table and boom frame.
q) If a deviation of load hook is detected, measure the crane inclination via a inclinometer on
the edge of slewing ring, and make sure the inclination is not more than 1% (±0.57°).
r) Inspection before slewing operation of the load:
Check the inclination of the ground in the slewing radius, and the checking method is the
same with what is described above.
3.9.2.4 Notes for crane operation
a) Estimate the weight and dimensions of load to be lifted in advance.
b) Use load lifting devices (wire rope or chain) correctly. Make the vertical line of the hook
pass through the center-of -gravity of the load.
c) If any part of the crawler crane or load handling devices come in contact with the
high-voltage power line, or emergent situation occurs, the operator should stop the vehicle
at once.
d) The load capacities as given in the load lifting capacity tables must be adhered to. The
loads given in the load lifting capacity tables must not be exceeded. Driving (or slewing)
too fast with a load, or setting up and loading on an uneven surface, and swinging of
suspended load should be avoided.
e) Diagonal pulling (slewing or travelling) of the load to be lifted which is still in contact with
the ground is prohibited.
f) It should be avoided that the load or auxiliary lifting device collides with structural members
of the crawler crane.
g) If the crane gets caught in a thunderstorm during operation, the following measures should
be taken at once:
–
Stop work on the crane immediately.
–
Always set down the load and boom frame on the ground.
–
Apply brake or lock winch and slewing gear.
–
Switch off the crane engine and cut off the power of load moment limiter and limit
switch
–
Ask all crane workers to leave away.
h) If the crane is struck by thunderbolt, the following checks should be performed:
–
Check whether there are burnt or damaged components
–
Check the performance of the electrical parts and load moment limiter
–
Check the associated components for functional work.
i) If earthquake occurs when the crane is operated, the following measures should be taken
immediately:
–
Stop work on the crane immediately
–
Always set down the load and boom frame on the ground.
For reference only.
Operators manual should be consulted and adhered to.
