Design Project: 1. Six screw jacks model JTW-50T-US-628-L-I

motorized screw jack hoisting sluice gates, worm gear screw jack gearboxes for raising and lowering canal gates. Small area water regulation makes a valuable contribution to the prevention of damage, whether it is caused by excess water or a lack of water. Sluice gate jacks are the ideal solution for this. They are used on streams and rivers, in sluices and power stations to regulate the water level and turbine capacity and to drain and flush reservoirs. In open water near towns, sluice gate jacks are used in emergency water extraction equipment for fire fighting. The range of systems available today is wide and varied to meet specific application requirements. Many modernization programs for the operation of canals that deliver water to the agricultural community involve the mechanization of canal gates. Sluice Gate Jacks provide a method of raising and lowering canal gates using electric motors / geared motors / worm gear reducers instead of human power starting

Steel protective pipe cover for anti-rust and anti-dust under worm gear screw jack base, when full retract stroke. 5. Bellows boots or

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 re

Pakistan 5 ton travelling nuts rotating screw type screw jacks lifting work platform for raise container 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 1227.5×1227.5mm, included all safety factors, max. loading capacity 1500kg, travel stroke up to 2068.5 mm, after calc

1 Ton Weight Water Barrier With The Pressure Is Hoisted By Double 20 Ton Worm Gear Screw Jacks 3000 MM Screw Length In Russia Customers technical details: According to the account of our engineers the weight of water barrier is to be 1 ton with the pressure. The width of our water barrier is 1500 mm, the length-3000 mm, The parameter of our motor is 7,5 kw with ,1450 rpm, and the reductor with 28 rpm, So we need a screw with a length-3000 mm and with the diameter -55-60 mm /12 pieaces. Solutions: Using 20 ton worm gear screw jack with lifting screw diameter 64mm, pitch 8mm, screw travel length 3000 mm. Following customers motor and the reductor, final output 28 rpm. 20T jack use high speed ratio with 1 mm travels per revolution of input shaft. ________________________________ Jacton Electromechanical Co.,Ltd Chang An,Dongguan,Guangdong,China Phone: 86 769 81585852 Fax: 86 769 81620195 Mobile: 86 135 32830851 Skype: jactonjack Email: sales@screw-jack.co
