Screw jack options
Travelling screw is where the acme thread moves linearly through the worm wheel in the casing
Travelling nut is where the acme thread is fixed to the worm wheel, and an external bronze nut travels up and down the thread
Motors - ac, dc and servo motors can be supplied directly connected by flange to the screw jack.
Protective tubes are often used with travelling screw models to protect the non-working side.
Safety nuts can be specified for travelling nut models to prevent catastrophic failures.
Stroke limit switches prevent over-stroking
Wear monitors and many other options are detailed in the catalogue.
On request we can configure customised multi-jack lifting systems. These typically include a brake motor, spacer couplings and right angle gearboxes.
