Snubber operation (5) Snubber (11) Passage |
When boom cylinders (1) or stick cylinders (8) move close to the end of the extension stroke, passage (11) is restricted by snubber (5). The movement of the piston rod slows down before the piston rod stops.

Snubber operation (retracting rod) (5) Snubber (12) Passage |
When stick cylinders (8) move close to the end of the retraction stroke, passage (12) is restricted by snubber (9). The movement of the piston rod slows down before the piston rod stops. The shock load is absorbed when the piston is slowed down.
