* JTS-Series Bevel Gear Jacks, also called Bevel Gear Screw Jacks, which includes Bevel

Gear Machine Screw Jacks and Bevel Gear Ball Screw Jacks. Available in 2.5-ton to 50-ton

static capacities, offer higher efficiency and greater speed than other worm gear mechanical

screw jacks. As an added benefit, JTS-Series Bevel Gear Jacks also act as bevel miter

boxes, making them an ideal choice for multiple units bevel gear screw jacks lifting systems.

As many as three output shafts may be specified for mounting motors, limit switches and

other accessories. JTS-Series Bevel Gear Jacks with single lead screws provide the benefits

of a self-locking screw, and bevel gear jacks with double lead screws offer even greater

travel speed.

* JTS-Series Bevel Gear Jacks major configuration devides the jacks into bevel gear jacks

translating designs, bevel gear jacks rotating designs, bevel gear jacks keyed anti-rotation

design. Upright and inverted type beve gear jacks are available. Standard lifting bevel gear

jacks screw end types such as top flange (top plate), clevis end (male clevis), threaded end

and plain end, also can custom to make kinds of lifting bevel gear jacks screw ends.

* JTS-Series Bevel Gear Jacks transmission ratios 1:1 and 1:2 (2.5-ton to 20-ton), 1:1.5,

1:2.5 (25-ton to 50-ton). Linear speeds up to 12mm per tun of input shafts. Can be driven by
