Variable Positioning, Rigid or Elastic Locking Gas Springs

Flaps and lids can be very heavy and hard to operate by hand. Chairs and desks must be adapted to the body height of the individual user to take ergonomic aspects into consideration. In these cases, locking gas springs from Stabilus will provide optimum weight equalization and user-friendly motion sequences during opening, closing, and positioning. Our products in the BLOC-O-LIFT line of locking gas springs are also available with variable locking, either rigid or elastic in the direction of tension or compression, depending on the desired setup.

Function of BLOC-O-LIFT Locking Gas Springs

A special piston / valve system, which separates the two pressure chambers in the spring, allows effortless variable locking. If the valve tappet is released from the outside and the exchange between the pressure chambers is interrupted, the gas spring will lock and hold even heavy loads reliably in the desired position. With the valve open, the linear spring characteristic curve of the BLOC-O-LIFT locking gas springs will provide an even increase in force over the entire range of motion.
