21 -SERIES Anti-Backlash for Screw Jacks The Anti-Backlash feature provides a reliable method to regulate the axial backlash in a screw jack for applications where there is a reversal of loading from tension to compression. The amount of backlash between the screw and worm gear nut can be adjusted (adjust shell cap) to a desired amount or a practical minimum. To avoid binding and excessive wear do not adjust backlash to less than 0.025mm. Removable cap to check wear by eye & gauge Adjustable Shell ap The Anti-Backlash feature also acts as a safety device, providing dual nut load carrying unit, when the worm gear becomes worn. A visual wear indicator is included as standard on all models and a feeler gauge can be used to measure the wear. This can be upgraded to use a sensor on request (consult Power Jacks).

23 -SERIES with Safety Nut Power Jacks metric machine screw jacks can be fitted with a safety nut, which provides 2 safety roles: 1. In the event of excessive wear on the nut thread the load will be transferred from the standard nut to the safety nut. This will also provide visual wear indication as the gap between the safety nut decreases to zero as the standard lifting nut wears. kn T kn T kn 2. In the unlikely event of catastrophic nut thread failure the safety nut will sustain the load. The safety of industrial and human cargo is therefore improved. There are several configurations for each safety nut device as they only work in one load direction. or this reason when ordering please supply a sketch of your application showing load directions. = oad direction - ompression T = oad direction - Tension Translating Screw Jack with Safety Nut The dimensions for these screw jacks are the same as the standard units except those detailed below. oad Direction - ompression () Model MT010- MT025- MT050- MT100- A B ØD ØE D E B DETAI A Dimension, G, ØH not applicable A Detail A = As per table Detail B = Same as standard MT screw jack oad Direction - Tension (T) Model MT010-T MT025-T MT050-T MT100-T Stroke + 5 Stroke + 10 Stroke + 15 Stroke + 20 G ØH H G DETAI B Dimension A, B,, ØD, ØE not applicable Detail A = Same as standard MT screw jack Detail B = As per table Model MT010 MT025 MT050 MT100 Wieght (kg) Rotating Screw Jack with Saftey Nut kn The dimensions for these screw jacks are the same as the standard units except those detailed below.

43 S-SERIES Anti-Backlash for Screw Jacks The Anti-Backlash feature provides a reliable method to regulate the axial backlash in a screw jack for applications where there is a reversal of loading from tension to compression. The amount of backlash between the screw and worm gear nut can be adjusted (adjust shell cap) to a desired amount or a practical minimum. To avoid binding and excessive wear do not adjust backlash to less than 0.025mm. Anti-Backlash Gear Adjustable Shell ap The Anti-Backlash feature also acts as a safety device, providing dual nut load carrying unit, when the worm gear becomes worn. It can also be fitted with a wear indicator for critical applications. This can be further upgraded to use a sensor for automatic detection (consult Power Jacks). The S-Series Anti-Backlash screw jacks are available with an inverted screw design for maximum design flexibility (refer to diagram on the left).

44 S-SERIES Anti-Rotation (Keyed) for Screw Jacks The Anti-Rotation feature for translating screw jacks stops the lead screw from rotating without the need for end pinning.

46 S-SERIES with Safety Nut kn Power Jacks metric machine screw jacks can be fitted with a safety nut, which provides 2 safety roles: kn kn 1. In the event of excessive wear on the nut thread the load will be transferred from the standard nut to the safety nut. This will also provide visual wear indication as the gap between the safety nut decreases to zero as the standard lifting nut wears. 2. In the unlikely event of catastrophic nut thread failure the safety nut will sustain the load. The safety of industrial and human cargo is therefore improved. There are several configurations for each safety nut device as they only work in one load direction. or this reason when ordering please supply a sketch of your application showing load directions.
