Chainlift was designed for lifting short travel, table type lifts.
The basic principle is identical - the chain is stored horizontally and forms a rigid pushing bar as it is driven through the drive housing, thus applying thrust under a platform.
The drive is generated by the rotation of pinions on rollers, forcing the links to lock and move through the housing.

Our vertical range comprises 5 products:
LinkLift 50 - LinkLift 50 R - LinkLift 80 - LinkLift 100 - LinkLift 100 R
LinkLift 50R * and LinkLift 100R * are renforced versions of the LinkLift. In these cases the chain is equipped with 2 additional rollers per link, whilst the drive housing has 2 additional pinions allowing the dynamic capacity to double.

The Duff-Norton line of screwjacks (mechanical actuators) includes mechanical actuators (machine screw and ball screw) ranging in size from 1/4 ton to 350 tons, stainless steel machine screw actuators, micro-miniature actuators, high duty cycle actuators, motorized machine screw and ball screw actuators, electric cylinders and motor control systems. Accessories include miter gear boxes, c-face motor adapters, limit switches, transducers, visual and digital position indicators, couplings, ball screws and ball screw systems, and locking rings. Mechanical actuators are also used for raising and lowering maintenance platforms, opening and closing air dampers, oven doors and sluice gates, and adjusting tooling machine beds, cable tension and workplace tables. In addition to the broad range of applications and industries for mechanical actuators, they are also used as alternatives to hydraulic and pneumatic systems.
