Excellent quality manual worm wheel lifter 10 ton 20in worm gear screw jacks handle for Canada customers order. Specifications: 10 tons capacity, upright translating screw configuration, gear ratios 1:8, Tr 58x12mm, stroke 500mm, top plate(flange) end fitting, two input shafts, attached handwheels 300mm(12") diameter.
The screw jack makes it possible to transform the rotary motion provided by an electric, pneumatic, or hydraulic motor or even a handwheel, into linear motion that allows push or pull vertical lifting and horizontal positioning. They can be used to lift, pull, move, or align any type of load with perfect synchronism, which is difficult to achieve with other types of actuators.They can be applied either with vertical mountings facingup or down, or with horizontal mountings.The screw jack is a device for lifting heavy loads by applying comparatively small at its handle. If the free shaft end of the motor is used as shaft for a slip-on emergency hand wheel, a device will be required that interrupts the power supply before the crank engages.Screw jacks come assembled, threaded, and ready for hookup. Connect a motor or hand-crank shaft to the screw jack shaft to lift, hold, position, and level loads.
1. Note: The dark gray figures in the tables indicates operational restrictions due to thermal limits. Selection of screw jacks using these figures should only be carried out in consultation with our engineers. When your selection is made within the areas shaded dark gray, you will need to reduce duty cycle or choose the bigger size screw jack in order to allow effective heat dissipation.
