Inverted Translating screw jack lifting system of high efficiency
Product Overviews
1. Screw Jack System Picture & Instruction :
Screw jacks lifting system structures include miter gearboxes, screw jacks, electric motor or gear reducer, hand wheel, pillow block bearings, jaw couplings and line shaftings.
Compared to fast speed hydraulic lifting system and pneumatic lifting system, screw jacks lifting system is not only for the simple load-supporting from several kilograms to heavy duty several hundreds tons, but also have many advantages such as self-locking without brake or locking mechanism, precisely positioning, full synchronization, manual operated or electric motor driven, quiet environment, easy installation and operation, maintenance free.
2. Screw jack system application
- Large satellite dish antenna movement (x, y, z axis)
- Workplace table adjustments
- Drive wheel adjustment to change conveyor flow stops
- Conveyor lifts, diverters
- Knife blade filter drum skimmer
- Furnace combustion gun adjustment
- Mechanical clutch linkage
- Vacuum furnace lid lifters
- Roll lifts
- Mandrel pushers sluice gates
- Low temperature valve operators
- Unwind stands
- Calender stacks
- High voltage switch gear die set tables
3. How to Choose a Screw Jack? Some questions you need answer pls.
Q1: The capacity is to load ? KG (it means how many Kg or Tons the screw jack need to lift or drop?)
The stroke is ? mm (it means the screw shaft length, such as 500mm)
The lifting speed is ? mm/second (it means how much time you want to use to finish the stroke? Such as I want to use 20 seconds to finish the 500mm stroke then can come out the speed is 25mm/s )

Q2: Which the screw top you need? Answer: I need (A B C D E F).
Q3: Manual type (Hand wheel driven) or electric motor driven type? Answer: I need type.
Q4: Screw movement (screw travelling up and down when working) or Nut movement (the nut travelling up and down when working)? Upright or Inverted? Answer: I need (A B E F)
Q5: Screw jacks linkage
Do you need two or above two sets screw jacks to linkage, if yes pls see the below screw jacks linkage scheme, if no pls ignore this.
Answer: 1. No need 2. Need, sets (2 /3 /4 /8 or other sets) screw jacks to linkage, ( I /T / L / H / U) )type ( Or you can mark it out on the below screw jacks linkage scheme picture).
For example, a 4-sets linkage H type ( without screw in this picture) as followIing:
