Trapezoid screw has a self-lock function it can hold upload without braking device when screw stops traveling.
2. General ball screw features: High efficiency, High speed, Lifetime longer but no self-lock function
Q2: The total capacity is to load dynamic KG ( KG static)
(it means how many Kg or Tons the screw jack needs to lift or drop?)
The stroke is _ mm (it means a removable distance of lead screw, 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 )
How often do you use the screw jack? How much time per time? .
Screw jack SWL2.5-120 performance parameters table as the below:
Q3: Which screw top you need? Answer: I need (Ⅰ/Ⅱ/Ⅲ/Ⅳ/Customized).
Q4: Manual type (Handwheel driven) or electric motor driven type or both driven type?
Answer: I need type. If electric motor driven type, your local Voltage and hertz?
Q5: Screw movement (screw traveling up and down when working) or Nut movement?
(the nut traveling up and down when working) Upright or Inverted?
Answer: I need （1-A,1-B,2-A,2-B）
Q6: Screw jacks linkage
Do you need two or above two sets to screw jacks to the linkage,
if yes pls see the below screw jacks linkage scheme if no pls ignore this?
Answer: 1. No need 2. Need, sets (2 /4 /6/8 or other sets) screw jacks to the linkage,
( I /T / H / U) )type ( Or you can mark it out on the below screw jacks linkage scheme picture).
3. What's the central distance between the two jacks? .
