The steel jack is standard equipment for tool and machinery shops, contractors, shipyards, agriculture and workshops:
our steel jack with fixed lifting claw can be delivered with different types of hand crank for lifting the jack shaft along the rack. It offers a very long service life due to its high quality spur pinion, precise worked crank gear as well as additional worked pawl. |
|
| Rack & pinion jacks load 1,5 t to 10 t (fig.) withself-locking security crank, keeps the charge in every required position - for pulling or pushings. Special versions on request: - different length of rack - different lift - drive shaft to connect several jacks - with internal professional brake and removable crank |
|
Rack & pinion jacks load 0,5 t and 1 t, with self-locking worm pinion for lifting, for lowering, adjusting and fixing of mechanical components, devices, machines, etc.. 0,5 t version also available in stainless steel
robust version with milled rack and hardened driving parts, for in- and outdoor applications
Special versions against additional charge:
- an other lift or length
- an other crank version
- an other fixing possibility
- an other surface treatment

| Power Jacks have been manufacturing rail jacks for over 70 years at their Fraserburgh site for track lifting, surfacing, lining and many other lifting procedures. The range comprises of mechanical, hydraulic and air powered units. The lifting capacity of the range starts at 7.5 Ton and goes up to 200 Tons. Models are manufactured in a variety of materials including aluminium for easy handling. |
|
| Roller screw jack provide higher performance compared to ball screw jacks. Ideally suited to applications where a high dynamic load, high accuracy, high speed and a long life are required. |

Joyce/Dayton - Established 1873
Joyce Bevel Gear screw jacks offer higher efficiency and greater speed than other mechanical screw jacks. At the same time, Bevel Gear S Series jacks still provide the benefit of a self-locking screw-no special brake is required to prevent the jack from lowering under load. Spiral bevel pinions increase strength for higher capacities.
Bevel Gear screw jacks also act as a miter gear box, making them an ideal choice for many multi-jack systems. As many as three output shafts may be specified for mounting motors, limit switches suppliers, readout devices and other accessories.
Bevel Gear screw jacks are also available complete with reducer or direct drive in a ready-to-run package.
Joyce bevel gear jacks come in translating screw (shown) and rotating screw (keyed for traveling nut) designs. Jacks are available with one of four standard screw ends or special ends to meet your requirements.

Joyce/Dayton - Established 1873
Joyce/Dayton Stainless Steel Machine Screw jacks are specifically designed for positioning or lifting applications in corrosive or other potentially contaminated environments. All exposed surfaces and components feature 316 or 17-4 stainless steel construction and bronze bushings. Nitrile rubber professional seals protect all internal mechanisms.
Unlike other stainless steel screw jacks, Joyce/Dayton SWJ series provide full lifting capacity. In most cases, these jacks can be easily retrofitted into applications where non-stainless steel screw jacks have already been installed.
Joyce/Dayton offers Stainless Steel Screw Jack models in capacities from 2 to 25 tons. Stainless Steel Screw Jacks come in translating screw, rotating screw (keyed for traveling nut) and keyed (shown).
Stainless steel screw jacks are available with one of four standard screw ends or special ends to meet your requirements. For increased travel speed, specify DSWJ double lead series.

Joyce/Dayton - Established 1873
Joyce Ball screw jacks feature a ball nut with integral ball bearings that recirculate along the surface of the manufacturer of ball screw. The significantly reduced friction between the ball nut and screw results in greater efficiency, with up to 2/3 less input torque required to move the load than a similarly rated machine screw jack.
Compared to Machine Screw jacks, Joyce Ball Screw Jacks
- Require less motor horsepower
- Allow higher travel speed
- Provide an extended duty cycle
Joyce Ball Screw Jacks are available in translating screw or rotating screw (keyed for traveling nut) designs. Translating screws are available with threaded, load pad, clevis or plain ends. Options include limit switches manufacturers, professional encoders, geared potentiometers, direct drive and reducer mounts, and protective professional boots. Joyce Ball Screw Jacks are ideal for single or multiple jack systems.
Unlike Machine Screw Jacks, Ball Screw Jacks are not self-locking. Because they will lower under load, a braking motor or other external braking mechanism is required.
