4.3 

Electrical and mechanical additional equipment 

4.3.1 

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

 

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. 

4.3.2 

Brake spring – C-spring 

 

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) 

4.3.3 

Regulating spring – R-spring 

 

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
