Linear actuator DJ805 with a self-locking is very useful. Linear actuator is a general auxiliary motor device, which is used widely in multiple fields. Linear actuators are power-driven devices that convert the rotation movement to repetitive linear movement. They could ;be used as an actuatingequipment to achieve long-distant control, concentrating control, or automatic control.

To halt the raising of linear actuators at any height and keep it this way, you need a linear actuator with self-locking function. Linear actuator DJ805G can bear up to a load of 12,000N (2697lbs), with distances cover up to 1000mm (39 inches). Our technical engineers would add a self-lock system on the inside of linear actuators, through torsion spring screw which relies on the friction produced by the spring and the contact face of the screw to keep the screw itself moving vertically. This tiny and easily-installed structure is placed on the front part of the linear actuators. https://www.hbactuator.com/posit...ing-linear-actuator.html
