It is possible to link two or more screw jacks by shafts, couplings and bevel gear boxes so that the lifting and lowering operations of all the screw jacks are perfectly synchronized. Even when loads are not evenly distributed, the screw jacks will ensure a perfectly synchronized movement of the load.

Two Jacks - Translating Screw Jack System includes double translating screw jacks, couplings, drive shafts, or miter gearbox, and motor (electrical drive) or handwheel (manual operation). Its efficiency 95%.

Two Jacks - Rotating Screw Jack System includes 2units rotating screw jacks, couplings, drive shafts, or miter gearbox, and motor (electrical drive) or handwheel (manual operation). Its efficiency 95%.

A three point lift system was devised using three screw jacks, bevel gearboxes, couplings and drive shafts. The system was designed to be quick and easy to use by motorized or hand operation while being self-locking. Using metric machine screw jacks on the screw provided a mechanism that was self-locking and minimum torque input for hand operation

Three Jacks - Translating Screw Jack System includes 3 units translating screw jacks, couplings, drive shafts, or miter gearbox, and motor (electrical drive) or handwheel (manual operation). Its efficiency 95%.

Three Jacks - Rotating Screw Jack System includes 3 units rotating screw jacks, couplings, drive shafts, or miter gearbox, and motor (electrical drive) or handwheel (manual operation). Its efficiency 95%.

Four of the most popular system configurations are the H, U, T and I configured jacking systems. Note that multiple screw jacks can be linked together mechanically or electrically. The latter is useful if there is no space for linking drive shafts.

Four Jacks - Translating Screw Jack System includes 4 units translating screw jacks, couplings, drive shafts, miter gearboxes, and motor (electrical driven) or handwheel (manual operation). Its efficiency 95%.

Four Jacks - Rotating Screw Jack System includes 4 units rotating screw jacks, couplings, drive shafts, miter gearboxes, and motor (electrical driven) or handwheel (manual operation). Its efficiency 95%.

We develop a complete six lifting points systems which included miter box, shafting, couplings and shaft support bearings. The key parts to move table screw jacks simultaneously and then hold the position. Self-locking, precision positioning, full synchronization, different multiple screw jacks systems arrangements, easy installation and operation

Complete eight points lifting systems with geared motors and couplings available. Multiple screw jacks can be combined into a lifting system. Powered by a geared motor, the jacks are connected often in an "H" configuration by couplings and bevel gears. We can supply complete lifting systems, talk to our Engineers.
