SG screw jacks

SG screw jacks (screw jacks) are mechanical devices used for linear movement of various elements, as pressing, lifting or lowering devices. Often used in smoke exhaust systems as regulators of various types of dampers. The use of jacks in systems for raising and lowering stages and/or moving entire rows of seats in theaters is very popular. The compact and simple construction allows the use of jacks in the most difficult conditions, e.g. in solar systems for precise "tracking" of the sun for the best use of its energy. The synchronization of the work of the lifts allows for lifting and lowering larger elements (boilers, vats, railway cars, etc.).
