Screw Jack System
Screw Jack System offers comprehensive lifting, pushing, pulling and position holding with precision for design solutions in a wide variety of industries. Highly accurate and extremely reliable machine screw and ball screw jacks are matched with an extensive range of drive, connection, motion control, safety, and protection components to provide a complete package from a single source.

Screw Jack Lift System

1.multi-jacks lift system
2.synchronous lift system
3.heavy duty,self-locking
4.precision positioning
5.customized travel length
6.electric motor driven

Two Lifting Points Systems

It is possible to link two or more screw jacks by shafts, couplings and bevel gear boxes so that the lifting and lowering operations of all the screw jacks are perfectly synchronized. Even when loads are not evenly distributed, the screw jacks will ensure a perfectly synchronized movement of the load.

Three Lifting Points Systems

A three point lift system was devised using three screw jacks, bevel gearboxes, couplings and drive shafts. The system was designed to be quick and easy to use by motorized or hand operation while being self-locking. Using metric machine screw jacks on the screw provided a mechanism that was self-locking and minimum torque input for hand operation

Four Lifting Points Systems

Four of the most popular system configurations are the H, U, T and I configured jacking systems. Note that multiple screw jacks can be linked together mechanically or electrically. The latter is useful if there is no space for linking drive shafts.

Six Lifting Points Systems

We develop a complete six lifting points systems which included miter box, shafting, couplings and shaft support bearings. The key parts to move table screw jacks simultaneously and then hold the position. Self-locking, precision positioning, full synchronization, different multiple screw jacks systems arrangements, easy installation and operation

Eight Lifting Points Systems

Complete eight points lifting systems with geared motors and couplings available. Multiple screw jacks can be combined into a lifting system. Powered by a geared motor, the jacks are connected often in an "H" configuration by couplings and bevel gears. We can supply complete lifting systems, talk to our Engineers.

Flexible Jaw Coupling

Jacton screw jacks are used alone or in multiple screw jack lift system arrangements that require flexible jaw couplings to transmit power to the input shaft. We provides flexible jaw couplings for use with screw jacks.

Overload Safety Couplings

Overload safety couplings are used to reduce electric screw jack and motorized screw lifting system damage, repairs and downtime by acting as torque limiters and overload protection. In the event of excessive torque the safety function disengages and the motor gets separated from the motorized screw jack drive system.

Connecting Shafts

Jacton connecting shafts is used to interconnect the input shafts of worm gear screw jacks that are used in a multiple screw jack lift system arrangement. The connecting shafts transfer the torque from the motor to the screw jack or from screw jack to screw jack.

Cast Iron Hand Wheel

A cast iron hand wheel is a convenient solution for manual operation screw jack or lightweight screw jack lift systems. They are mounted directly to the jack input shafts(worm). Can be adapted for use on self locking screw jacks from 250kg up to the 20 ton load capacity model.

Aluminum Handwheel

Aluminum Handwheel is a convenient solution for hand wheel manual screw jack or light load screw jack system. Aluminum Handwheel with folding handle directly coupled with screw jack worm shaft, only suitable self lock screw jack with load capacities 0.25 ton, 0.5 ton, 1 ton, 2 ton, 2.5 ton, 5 ton.

Three Phase Electric Motor

Three phase electric motor mounts allow direct coupling to the motor shaft on either the right or the left side of the screw jacks input shafts. These assemblies are available for all screw jacks sizes.

Single Phase Induction Motors

Some customers want to import our electric screw jack for personal use like small factories, or laboratory use, or university use, they have not three phase voltage there, so will required worm gear screw jacks couples with the single phase induction motors. The voltage includes 110V, 120V, 220V, 230V, 240V etc, with 50Hz, or 60Hz.

12V 24V DC Geared Motor

Some customers have not AC voltage at their working space, must need the dc electric battery as power supply, for example, solar tracking system with dc geared motor screw jacks.

Proximity Switches

Proximity switches can be called proximity limit switches, proximity sensor switches or inductive proximity stroke end switches. Proximity switches are available for worm gear screw jack with translating screw only.

Limit Switches

Every motorized worm gear screw jacks must be controlled so that power to the motor is turned off and the brake engaged before the limits of mechanical travel are reached. JACTON limit switches senses extension shaft rotation and provides switch contact closures that can be used to control motors. JACTON limit switches is electromechanical device,

Pillow Blocks

JACTON pillow blocks are important components in screw jack lift system. Pillow blocks is sometimes needed to support long connecting shafts. Pillow blocks include self-aligning replaceable bearings that are pre-lubricated. They are suitable for use under normal duty operation.
