compactlockable

The standard-type BLOC-O-LIFT is an elastic-locking gas spring that’s perfect for easy, comfortable adjusting of furniture and panels. It also enables safe positioning of these applications anywhere in range. It’s right at home in the backrest adjustment mechanism of swivel chairs, where a subtle rebound of the spring is highly sought after in support of ergonomics. Locking in any position is made possible by a special piston valve system that separates the two pressure chambers in the spring such that gas cannot travel from one chamber to the other. When the valve is open, the BLOC-O-LIFT provides force assistance, supporting user-friendly component travel based on predefined damping characteristics. When the valve is closed, the gas spring locks gently in the desired position with a slight rebound. The standard BLOC-O-LIFT is charged with gas and is installed with the piston rod oriented downward. elastic locking in any position; optimal counterbalancing during lifting, lowering, opening, and closing comfortable cushioning and damping upon impact or at the peak of pulse-type loads flat spring characteristic curve (i.e., low increase in force even with strong forces or long strokes) compact design, minimal space requirement simple installation thanks to an assortment of end fittings
