How do hydraulics affect delimbing performance?

· Delimbing force

Delimbing force is determined by the cylinder piston size and the oil pressure.

Refer to the technical table for calculated forces based on cylinder dimensions and pressure

Delimbing force in kN
Stroke cylinder piston diameter
Oil pressure 40mm 50mm
170 bar 21.0 32.7
180 bar 22.2 34.7
190 bar 23.4 36.6
200 bar 24.7 38.5
210 bar 25.9 40.4

· Delimbing speed (forward stroke)

Within the specified delimbing diameter range: Higher oil flow results in faster forward stroke motion

· Delimbing speed (return stroke)

During the return stroke, oil exits the cylinder:
– Excessive back pressure slows down the movement
– A sufficiently large return hose is essential to ensure efficient cylinder emptying and fast return speed
