Safety central for lifts

Western Specialty Equipment has launched Nussbaum Lifts of Germany which includes the release of a smaller (48,000-pound/22,000-kg set of 4) version of their regular 66,000-pound capacity (set of 4) mobile columns. At the heart of these hydraulic columns is the Nussbaum “Safety Star Technology” cylinder (SST for short). A locking nut around the pistons seats onto the top of the cylinder any time the lift stops creating a positive lock in any position. In addition to the locking system, the safety nut also doubles as an encoder measuring the stroke of the cylinder. Every rotation or partial rotation equates to cylinder stroke and with the SST system the stroke can be measured to 0.1 mm.
