Description: Slack Rope Valve for separate installation.It prevents the slack rope condition caused by the lowering of the ram when the car is suspended in the safeties or resting on the buffers.

Adjustment: The Slake Rope Valve is adjusted by turning the screw KSB ‘in’ for higher pressure and out for lower pressure. With KSB turned all the way in, then 5 turns back out, the unloaded car should descent when Manual Lowering is opened. Should the car not descend, KSB must be backed off until the car just begins to descend, then backed off a further half turn to ensure that with cold oil, the car can be lowered as required.
