9 Lift Capacity Calculation of the Excavator
9.1 Brief introduction and choosing the lift working condition:
Notice!
– Brief introduction: knowing from the calculation, the excavator force bearing
badly when it's under the digging condition, so this calculation will not calculate
the lift load determined by the assembly intensity of the working device, swing
platform and the bracket.
– Choosing the working condition:
– In this calculation, the lift point is at the bucket pivot mounting pin on the arm,
the maximum lift weight not including the bucket weight.
o
Under the still load tipping limit condition, the rated lift load is 75% of the
maximum load;
o
Under the hydraulic limit condition, the rated lift load is 87% of the maximum
load;
–
Lift scope figure of excavator is shown as the following Figure1:

Notice!
As well as the lifting conditions,the length of the arm also affects the permitted lifting
capacities and the stability of the machine. Compare the dimensions of the machine
arm with the ditails given in the lifting capacity tables, in order to use the correct
lifting capacity table for your machine.
