JBG10 Quick Lifting Screw Jack Pictures
Bevel Gear Ball Screw Jacks use a ball screw and nut made from hardened alloy steel with hardened bearing balls carrying the load between nut and screw. The addition of a high efficiency ball screw and nut reduces the required input torque to approximately one-third the torque required for the Worm Gear Machine Screw Jack. Bevel Gear designs are available with optional accessories such as boots, top plates, and clevis mounts. Note: all bevel gear ball screw jacks are without self-locking function, required a brake motor or external locking device to hold the position.
