Screw Jack Miter Gear Boxes

Joyce miter gear boxes are specifically engineered for use with Joyce jacks and actuators in multiple jacking systems. Miter gear boxes used in such systems effectively raise unevenly distributed loads. When driven shaft turns per inch of travel are the same, total synchronization is assured because all models have a uniform lifting speed. Arrows in assembly drawings below indicate shaft rotation.

All standard Joyce miter gear boxes are 1:1 ratio, other ratios are available in the RC series units. Four-shaft units are also available in the RC-18 through RC-204 and the MK series.
