
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.

Built-in valves in "open position" result in an extension of the
lifting and lowering times for short lift thrusters of approx. 0.4 to
1.0 seconds and for long lift thrusters of approx. 0.7 to 2.0
seconds.

The desired lifting/lowering time is set from the outside of the
thruster in an upright position.

Built-in C-spring to generate the braking force.

The specified braking force of the C-spring is generated at 0 ...
Maximum of the nominal lift reached (⇒ Technical data chapter)

Damping of the load changes when the brake is applied

The regulating spring is only effective in conjunction with a brake
spring

The installation dimension (A) of the thruster does not change

When determining the operating point of the brake, the spring
characteristic curve must be taken into account

Main application: EdEx regulating brake
