The longer the stroke, the less load it can lift, considering the compression limit of the screw jack. It can powered by motor, belt or handwheel. Can be mounted uprightly, horizontally or invertedly for different applications with different screw end. It is stable, accurate and space saving.
Trapezoidal type screws are typically self locking. This function, however, depends on a variety of parameters, including, but not limited to screw pitch, screw jack ratio, lubrication, vibration, mounting position, etc. A brake or brake-motor may be required to guarantee holding position, please consult JACTON during the design process. A brake is recommended for all applications involving vibration.
