Screw Jacks

INKOMA-GROUP precision screw jacks are high quality engineered products for precise lifting, lowering and pivoting of loads, and are, under normal operating conditions, maintenance free. Designed for use in a wide range of Industrial machinery and with a load capability from 2.5kN to 2000kN, the screw jacks can be supplied as single components or part of a complete lifting system, with bevel gearboxes, cardan shafts and motors. Many specials are available to suit even the most arduous applications and harshest environments, with 2D and 3D CAD drawings available to download via our website.

Cubic Screw Jacks

The INKOMA Cubic Screw Jacks are available in 3 different models with selection based on performance and application requirements. Further details can be found on each of the ranges below and for further technical information or assistance please do not hesitate to contact us.

HSG Screw Jacks

INKOMA screw jack housings have a cubic form and are machined on all faces. The use of high quality grey cast iron or aluminium in the production of the housings guarantees a long life and high operating margin. Motor and screw jack assemblies may be mounted in any attitude. Compressive, tensile and offset loadings can be tolerated even under extreme operating conditions. The worm gear is manufactured from quality alloy steel and is ground and ion-nitrided. 2 gear ratios are available and these are matched to the spindle pitch.

DSH Screw Jack

The INKOMA DSH screw jacks have no internal gear system. Instead a special torque motor is used to directly drive the ball screw spindle resulting in smooth backlash free rotation. IN the DSH system there are virtually no mechanical losses. Specially selected bearings ensure the spindle can withstand both tensile and compressive loads. The compact drive unit has a rigid construction and is suitable for high dynamic applications, Seven cycles per second and lifting speeds of 32m/min are achievable. Repeatable positioning accuracy is also very high. The DSH-units can be synchronised when working together in a system, allowing the screw jacks to be positioned at different levels within the application. The DSH system has high energy efficiency. During operation the torque motor  is used to control the speed and hold position of the ball screw spindle. An integrated brake is also available for increased safety.
