Four Screw Jacks Lifting Platform Assembly Drawings And Installation Instructions In Singapore


 Singapore customers 4 screw jacks lifting table includes 4 pieces JTW-10T upright rotating screw jacks with bronze travelling nut, 1 piece JTP140 1:1 ratio right angle miter gear box 3 way, 2 pieces JTP140 1:1 ratio right angle miter gear boxes 2 way, 13 pieces FL28/38 steel jaw couplings, 4 pieces flange type road bearings, 6 pieces linking bars, 1 piece electric motor.

 Suggestions When Assembly Screw Jacks Lifting Table
1. The foundation for the screw jack should be rigid enough to maintain correct alignment with connected machinery and have sufficient strength to support the maximum load.
2. It is extremely important that the screw jack be installed so that the lifting screw is perfectly plumb and all connecting shafts are aligned with the worm shaft.
3. After precise alignment, each member must be securely bolted and if possible doweled in place. Doweling will assure exact repositioning if ever removed. It is essential that a gear unit be securely bolted down to the foundation using bolts of proper diameter to fit the mounting holes.
4. After the screw jacks, linking bars, couplings, right angle miter gear boxes and electric motor are coupled together and aligned in a system, there should be no signs of binding or misalignment.
5. The foundation of the screw jack is critical to insure alignment. Mount the jack and check that the axis of the lifting screw is parallel to the movement of the load and centered with respect to the load. Shim under the base to achieve this if needed. Both eccentric load or side load will cause premature wear and possible bending and failure of the screw jack. Once the alignment is correct hand tighten the mounting bolts.
6. The next step is to align the input shaft with the worm shaft of the screw jack. This alignment can be just as critical to proper operation. Test the alignment by rotating the shafts by hand and fully extend the lifting screws.

Anti-Backlash Screw Jacks Screw jacks are used for positioning loads in numerous applications, however when the load direction alternates between tension and compression within the operating cycle and a high position accuracy must be maintained then a specific type of screw jack is required. The Anti Backlash Machine Screw Jacks is recommended for such applications, as it is able to reduce the axial backlash between the lead screw and the trapezoidal screw thread in the gear to a practical minimum. Axial backlash exists in standard screw jacks as the "gap" or "play" between the flanks of the lead screw thread and the internal thread on the worm gear nut. This gap or play is due not only to normal manufacturing tolerances, but to the fact that there must be some clearances to prevent binding and galling when the screw jack is operating under load. In most applications either the load direction is constant so axial backlash does not occur or the position error
