Joyce worm gear machine screw jacks lift and precisely position loads (250 pounds to 250 tons). Upright or inverted jacks operate at full capacity in tension or compression. WJ and RWJ, single lead jacks are self-locking. DWJ and DRWJ, double lead jacks offer increased travel speed and require a brake or external locking device to hold position.

Joyce BG150S and BG150D bevel gear jacks with a 7.5-ton static capacity, offer higher efficiency and greater speed than other mechanical screw jacks. As an added benefit, these mechanical actuators also act as miter boxes, making them an ideal choice for multi-jack systems. As many as three output shafts may be specified for mounting motors, limit switches, readout devices and other accessories. BG150 jacks with single lead screws (S series) provide the benefits of a self-locking screw, and bevel gear jacks with double lead screws (D series) offer even greater travel speed.

Joyce 100 kN metric screw jacks are specifically designed for applications that must be fully metric. Upright or inverted these jacks operate at full capacity in tension or compression and are available in Translating, Keyed for non-rotation, and KFTN designs.

Joyce 2-ton stainless steel worm gear machine screw jacks lift loads up to 2 tons. These mechanical jacks are specifically designed for applications that are located in wet, corrosive and harsh environments. Upright or inverted, these jacks operate at full capacity in tension or compression and are available in Translating, Keyed for non-rotation and KFTN designs.

These Joyce electric cylinders lift and position up to 2.5 tons, achieve travel speeds up to 291 inches per minute, and raise loads up to 44 inches. They are well suited for industrial environments where protection of the lifting screw mechanism is critical and low maintenance is desired. Requiring only electric power, Joyce electric cylinders may also be used in place of hydraulic cylinders, eliminating the cost and potential for leaks associated with hydraulic systems.
