Product Description

2.5 Ton Hand Operated Screw Jack Lift for industrial vintage cast iron crank dining crank table base. Hand wheel screw jack with 2.5 ton capacity, upright installation, translating screw configuration, gear ratios 1/6 (one rpm input travel length 2 mm), 30mm diameter ACME screw and 12mm(2P) screw leads(pitch) as standard, stroke 300mm(12"), top plate(flange) end fittings, two input shafts, attached hand wheel 200mm(8") or 300mm(12") diameter, couplings and drive shafts.

 

A manual screw jack is consist of a hand wheel and a complete worm gear screw jack. All screw jacks can be moved manually via a handwheel. To do this, one input shaft shall be available on the screw jack for the connection of the handwheel. The screw jack makes it possible to transform the rotary motion provided by a handwheel, into linear motion that allows push or pull vertical lifting and horizontal positioning. They can be used to lift, pull, move, or align any type of load with perfect synchronism, which is difficult to achieve with other types of actuators.They can be applied either with vertical mountings facingup or down, or with horizontal mountings.
Manual screw jacks are available in load capacity 0.25 ton, 0.5 ton, 1 ton, 2 ton, 2.5 ton, 3 ton, 5 ton, 10 ton, 15 ton and 20 ton, heavy load larger than 20 ton capacity, manual operated screw jack is not recommended. They are ideal solutions for applications where electricity or power generators is inconvenient or dangerous, or in case of power failure, light weight, low duty cycle, low speed, low target cost, short stroke, and intermittent positioning applications. If must be not backdriving, a self locking machine screw jack with handwheel is the best choice. If high speed ball screw jack with handwheel, locking mechanisms need to be considered. If a brake motor is used, the brake shall be un-clamped firstly, so to allow for movement.

Cast Iron Hand wheel Diameter 125mm, 160mm, 200mm, 250mm, 300mm and 400mm, larger diameter handwheel is available, please consult JACTON Industry. The recommended screw jack with 0.25 ton, 0.5 ton, 1 ton, 2 ton, 2.5 ton, 5 ton, 10 ton, 15 ton, 20 ton capacities are available in matching cast iron handwheel for hand-operation application.

Aluminum Hand wheel with Folding Handle Diameter 125mm, 160mm and 200mm. The recommend screw jack 0.25 ton, 0.5 ton, 1 ton, 2 ton, 2.5 ton, 5 ton capacities are available in matching aluminum handwheel for hand-operation application.

In order to precise position display of the travel length, the worm shaft adds a digital position indicator which measures the rotation and display a corresponding position in a counter window. There are three sizes position indicators: 04 series position indicator 4 numbers with 14mm hollow shaft, 09 series position indicator 5 numbers with 20mm hollow shaft, 10 series position indicator 5 numbers with 25mm or 30mm hollow shaft. Note: inapplicable motorized screw jacks.
