2 02 Power Jacks More than just a screw jack

3 Power Jacks are a manufacturer focused on providing customers with the best engineered solution for precision linear actuation, power transmission and mechanical jacking. Our expertise has been built on a history of engineering craftsmanship and design dating back to The facility in Scotland is the UK s largest screw jack manufacturing facility, that uses the latest engineering technologies to deliver quality products (S N ISO 9001:2008) that offer reliability, performance and economy. Power Jacks is synonymous with screw jack technology and its development. We have been involved with Screw Jacks since the product was invented in the late 1930's and this gives us unparalleled experience in the design and manufacture of both standard and special designs. omplimenting the screw jacks the Power Jacks portfolio also includes the design and manufacture of spiral bevel gearboxes, electric linear actuators and planetary roller screws. This enables us to offer our customers a complete linear motion and power transmission system and solution. We know our customers demand our engineering expertise to help find a solution for their applications. We take pride in designing and delivering the best solution. This is what defines the Power Jacks range. 03

6 Introducing the new -Series Screw Jack range from Power Jacks, delivering new levels of versatility and quality. reated by a team of experienced design engineers, the focus was to provide our customers with a new compact cubic Screw Jack, which offers versatility in mounting methods. In addition to this, we wanted to design a jack that had the perfect combination of excellent performance, a long lasting service life, durability, flexibility and an extensive accessory list. Perfect for industrial applications operating individually or as a multi unit jacking system. ompact Durable Versatile Dynamic Over 140 Million Standard onfigurations. 4 Standard Screw Jack Designs Standard Anti-acklash* Anti-Rotation* Safety Nut Anti-Rotation can be combined with standard, anti-backlash and safety nut designs. * Translating screw configurations. Gearbox Housing Is one of the most functional features of the -Series screw jack. Using a rugged cast housing made of either a highly durable SG Iron or Aluminium. This provides a strong housing that firmly and accurately holds the gear set in a reservoir of chosen lubricant suited to the most industrial demands. Reliable Worm Gear set Proven design used in millions of screw jacks. orced Grease ubrication Of lead screw. Radial lubrication holes on the worm gear allow the worm shaft to force grease through directly onto the lead screw threads.this lowers friction and operating temperature while increasing life. orrosion Protection To suit all economic needs.

22 -SRIS Anti-acklash for Screw Jacks The Anti-acklash 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-acklash 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). Dimensions for Anti-acklash Anti-acklash Gear The dimensions for these screw jacks are the same as the standard units except those detailed below.

24 -SRIS 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 MT0010 MT0025 MT0050 MT0100 A ØD Ø D DTAI A Dimension, G, ØH not applicable A Detail A = As per table Detail = Same as standard MT screw jack oad Direction - Tension (T) Model MT0010 MT0025 MT0050 MT0100 Stroke + 5 Stroke + 10 Stroke + 15 Stroke + 20 G ØH H G DTAI Dimension A,,, ØD, Ø not applicable Detail A = Same as standard MT screw jack Detail = As per table Model MT0010 MT0025 MT0050 MT0100 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.

30 Introducing the high performance S-Series screw jack range from Power Jacks. To meet the increasing industrial demands on machine screw jacks our team of experienced design engineers set out to provide our customers with a new high performance cubic machine screw jack. It has typically 50% higher duty cycle capabilities than standard machine screw jacks, thus reducing the need for ball screw jacks or larger de-rated machine screw jacks in high duty applications. In addition the range is engineered to have a long lasting service life, high durability, large selection of configurations, versatile mounting and an extensive accessory list. Ideal for applications that demand more from a machine screw jack, but do not warrant a ball screw jack. Installed singularly or as part of multi-unit jacking systems. Over 350 Million Standard onfigurations per Model Type. 4 Standard Screw Jack Designs Standard Anti-acklash* Anti-Rotation* Safety Nut Anti-Rotation can be combined with standard, anti-backlash and safety nut designs. * Translating screw configurations. Gearbox Housing Design optimised for high thermal efficiency. Recognisable by the exterior fins, which increase surface area. The housing is cast using a highly durable SG Iron. This provides a strong housing that firmly and accurately holds the gear set in a reservoir of chosen lubricant suited to most industrial demands. Reliable Worm Gear Set Proven gear geometry used in millions of screw jacks. Oil illed Gearbox or optimum lubrication and cooling of the worm gear set at up to 3000 rpm input. ead Screw Grease Rated for extreme pressure to ensure correct lubrication at all rated loads. orrosion Protection To suit all economic needs.

46 S-SRIS Anti-acklash for Screw Jacks The Anti-acklash 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-acklash Gear Adjustable Shell ap The Anti-acklash 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-acklash screw jacks are available with an inverted screw design for maximum design flexibility (refer to diagram on the left).

49 S-SRIS 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.
