Lift, lowering or throttle valve (H, S, D)

34 / 71

With a built-in lifting, lowering or throttle valve, the lifting or
lowering times as well as both times together can be extended
continuously. The adjustable minimum values reach 10 to 20
times the normal values.

Installed valves in the "Open" position result in the following
prolongation of the lifting and lowering times:
– on short lifting devices from approx. 0.4 to 1.0 seconds
– on long lifting devices from approx. 0.7 to 2.0 seconds.

The desired lifting and/or lowering time is set from the outside of
the ELHY ® thruster in an upright position.
Quick lowering circuit
By using three-phase motor capacitors or by short-circuiting the stator
winding via a contactor, the lowering times are reduced by approx. 15
%.
