Consider all application constraints then choose a product that looks suitable for the intended application. View our compare the range if you need help choosing which Screw Jack best meets your requirements then, calculate the power and torque requirements. This is a 5 step process:

• Screw jack Input Speed
• Operating Input Power (kW),P
• Operating Input torque
• Screw jack start-up torque
• Mechanical Power and torque check

'H' and 'U' configured jacking systems are typical and include screw jacks, bevel gearboxes, motor, reduction gearboxes, drive shafts, couplings and plummer blocks. Screw jack arrangements or configurations can be built in many formats with the use of bevel gearboxes which allow the direction of drive rotation to be selected on assembly. The gearboxes come in 2,3 and 4 way drive types. See Neeter Drive Bevel Gearboxes for more details.

See FAQs for configuration examples.

1. Modifications to the standard screw jacks
This would include non-standard painting or plating of the housing, 2 or 3 start threaded lifting screws, stainless steel lifting screws or worm shafts, increased closed heights, extended worm shafts, opposite threading of lifting screws, etc.

2. Additions to the standard screw jacks
Items such as wear indicators, safety nuts, rotation monitoring kits, special lifting screw end fittings, encoder adapter flanges, etc.

3. Completely special screw jacks
Where a modification of our existing range is not practical we have the facilities to design and manufacture screw jacks tailored specifically to your requirements.
