Motorized worm gear screw jack (translating ball screw)
2 - 30 ton | ComDRIVES® JOYCE

Joyce Ball Screw ComDRIVEs combine a ball screw jack, motor and gear reducer into a single compact unit. ComDRIVEs are available in 2-ton through 30-ton capacities. Available in Translating, KFTN, and double clevis designs, they provide travel speeds up to 55.5 inches per minute. Ball screw ComDRIVES require up to two-thirds less input torque to move the load than a similarly sized machine screw jack ComDrive. They require a brake motor or external locking device to hold position.
