Gas springs from STABILUS have already been used in medical and rehab technology for decades. Our BLOC-O-LIFT gas springs in particular. They are used in adjustable operating tables and mobile walking aids. In these locking gas springs, a special piston valve system allows easy force-assisted adjustment and safe, variable locking. The latter can be unyielding or with a gentle bounce. The BLOC-O-LIFT OR and the BLOC-O-LIFT OBT gas springs are two interesting variants. The OR stands for the override function which will protect the application from overload in both the tension and compression directions. The OR gas spring is typically used as a movable, positionable link element in head or foot sections of massage tables and treatment chairs. The acronym OBT stands for Over Bed Table. This variant is the ideal design solution for patient nightstands. It allows variable height adjustment with rigid or elastic locking in the compression direction, and the upward movement of the table does not require actuation. The BLOC-O-LIFT column is a unique product in this gas spring series. This self-supporting gas spring for height adjustment by foot pedal is installed in physician’s chairs. The HYDRO-LIFT gas spring is a non-locking gas spring, it is often used when movable components need to be adjusted in defined positions. In addition to force assist, a piston package with a valve closing mechanism allows variable positioning over the entire adjustment range. Typical applications are the variable adjustment of foot elements in hospital beds or the flexible adjustment of monitor brackets. One special characteristic of this is that it can compensate major weight fluctuations.Fore more information ,please visiting http://www.bossgoo.com/
