3-40 ZCC1100H Crawler Crane
3.9 Crane operation with a load
Before beginning any work, the crane operator must be convinced that the crane is in safe
operating condition. All safety devices, such as load moment limiter, hoist limiter switches, and
brakes, etc., are in good working order.
a) The load moment limiter must be set according to the current crane configuration.
b) The lifting height of crane as given in the load capacity charts must be adhered to. The
load given in the load capacity charts must not be exceeded during operation.
c) The crane operator must know the weight and dimensions of the load before operating the
crane.
d) Lifting device, slings and fixed pulley block must be set in accordance with specified safe
operation requirements.
e) Make sure that the total weights of lifting device, wire rope and the actually lifted load won
’t
exceed the rated lifting capacity, referring to table 3-7.
Table 3-7 Calculation of lifting capacity
Items Weight (lb / t)
Rated lifting capacity 66150 / 30
Weight of load hook 2205 / 1
Weight of wire rope 22 / 0.1
Weight of actually lifted load 63724 / 28.9
3.9.1 Counterweight
Extend the crawler carrier fully, then we can get that the weight of the rear counterweight is
61740 lb (28 t) and that of central counterweight is 22050lb (10 t).
DANGER
If the counterweight is not installed properly according to the lifting capacity chart, there
is a danger of the crane toppling over.
For reference only.
Operators manual should be consulted and adhered to.
