Working diagram
C = Radius / dumping radius
J = Height of boom head sheave
centre above ground level
K = Length of clamshell
(according to manufacturer‘s
specification)
Digging diagram
C = Radius / dumping radius
D = Max. digging radius = approx.
C + 1/3 to 1/2 J
E = Digging depth = approx.
40 - 50% of C
J = Height to centre rope pulley
boom head
Max. capacities in metric tonnes do not exceed 66.7% of tipping load.
Capacities in duty cycle operation are for reference only and are not programmed in the LMI system.

Max. capacities in metric tonnes do not exceed 75% of tipping load.
Capacities in duty cycle operation are for reference only and are not programmed in the LMI system.
The size of the bucket has to be determined according to local conditions.
