HLA - High Performance Linear Actuator

Description for HLA - High Performance Linear Actuator

Another versatile drive element is our high-performance linear actuator HLA. The HLA combines the advantages of the proven high performance worm gear screw jacks HSE and the electromechanical screw rams with tubular construction ALSR. The linear actuator is consisting of a drive mechanism with two possible transmission stages as well as a shaft and thrust tube design and can be used as an individual drive or as in multi-screw lifting systems.

The design of the shaft and thrust tube system has a corrosion protected or hard chromium-plated finish respectively, and ensures optimum guidance and mechanical protection of the screw. Innumerable motor variants can be provided by means of various motor mounting flanges and couplings. The product is completed by a wide range of accessories, such as lift limitation, various head designs and short safety nut.
