FAQs

Q1. What is a screw jack and how does it work?

A screw jack is a mechanical actuator that converts rotary input (from a motor or hand wheel) into precise linear motion via a worm gear and lead screw mechanism, used for lifting, lowering, or precisely positioning heavy loads.

Q2. What load capacities does GPRO's screw jack range cover?

GPRO manufactures screw jacks across a range of load capacities for industrial positioning and lifting applications — share your required lifting load and stroke length for a matched specification.

Q3. Can multiple screw jacks be synchronized for even platform lifting?

Yes, screw jacks are commonly used in multi-jack systems connected via a common drive shaft (or synchronized electronically) to lift large platforms, molds, or structures evenly across multiple points.

Q4. What's the difference between a translating and non-translating screw jack?

A translating screw jack has a rising/lowering screw shaft that moves through the housing, while a non-translating (rotating screw) jack keeps the screw stationary in length and moves a traveling nut instead — GPRO can advise which suits your mounting arrangement.

Q5. What is the typical lifting speed and efficiency of a mechanical screw jack?

Lifting speed depends on the screw lead and input RPM, while efficiency is generally lower than ball-screw designs due to sliding thread contact — GPRO can provide exact figures for your selected model and ratio.

Q6. Does GPRO offer custom stroke lengths and mounting options for screw jacks?

Yes, GPRO custom-engineers screw jacks with specific travel length, mounting base, and input configuration (motor, hand wheel, or shaft-driven) to match your equipment design.
