Per screw jack lift systems parts includes 4 pcs 5t travelling nut rotating screw jacks, 2 pcs 1:1 ratio spiral bevel gear boxes, 5 pcs linking bars, 11 pcs couplings, 4 pcs steel plates, 4 pcs flange type pillow block ball bearings, 1 electric motor and 2 sets forward & reversible switches and contractors.

The linking bars, worm shafts of jacks, input & output shafts of gear boxes, output shaft of motor must be are installed and aligned. So all parts center height must be same, jt25 gear boxes are 90 mm, 1.5kw motor is 90 mm, jacks are 61.5 mm matching steel plate thickness 28.5mm, equal to 90 mm. So the main three parts center height is same with 90 mm. Easy to install them inline alignment.

The screw jack lift systems position is 1227.5x1227.5mm, included all safety factors, max. loading capacity 1500kg, travel stroke up to 2068.5 mm, after calculation, lifting screw total length 2282.5 mm. Lifting speed about 415 mm/min. Because lifting screw is very long, assured the whole lift system stable for linear motions, at the top end, extra additional 4 pcs flange type pillow block ball bearings to fix the long lifting screws, and extra additional guiding supports for the lift system.
