Product Description

Hand wheels are available for Linear Power Jack so that it can be easily used for manual operation. Hand wheels are used for self-lock equipped Linear Power Jacks (Machine Screw Type) only. Because Linear Power Jacks (Ball Screw Type) and Linear Power Jacks (High Lead Screw Type) are not equipped with a self-lock, the input shaft may be reversed by a load, therefore, it is dangerous to use the hand wheel. Hand wheel efficiency is determined by the required torque for a specified load and the diameter of the hand wheel. Also, vibration and shock may cause self-lock failure, in which case a brake unit is recommended. 
Hand wheels must not be mounted on the drive shaft when not operating the screw jack. Separate storage is required! Use of Screw Jacks Fitted With Emergency Stop Disc: To prevent over travel of the lead screw, a stop disc or nut can be fitted to a screw jack that is hand operated. It should not be used as a full power stop.





All JACTON screw jacks with handwheels are ideal solutions for applications where electricity or power generators is inconvenient or dangerous, light weight, low duty cycle, low target cost and short travel length. Available in load capacity 1/4 ton, 1/2 ton, 1 ton, 2 ton, 2.5 ton, 3 ton, 5 ton, 10 ton, 15 ton and 20 ton, heavy load larger than 20 ton capacity, handwheel manual operation is not recommended. There are two types hand wheels, one is cast iron handwheels, another aluminum handwheels. The cast iron handwheels sizes 100mm, 125mm, 160mm, 200mm, 250mm, 300mm, 400mm and 500mm. The aluminum handwheels sizes 100mm, 125mm, 160mm, 200mm.
Screw jack housings can either be a foot-mounted cast, most common in the US, or the housings can be cubic-machined on all six sides-offering more flexibility in mounting. Screw jacks can be used individually, manually operated, or motorized, or in systems up to eight screw jacks or more, all driven in unison by a common motor or gearmotor. Each screw jack is available with a number of variations, including travel distance, ratio, I/O shaft configuration, motor flange option, end of screw options (Top Plate, Threaded, Plain, Forked, Clevis), protective tube and protective bellows.
