Worm gear screw jacks not only can be used by single unit, but also can be used by multiple units. Multiple screw jacks can make up to a screw jack system together with spiral bevel gearbox,connecting shafts, couplings and motor etc. A screw jack can includes two screw jacks,three screw jacks,four screw jacks,six screw jacks and even more screw jacks.
Screw Jack Systems offer comprehensive lifting and positioning design solutions for a wide variety of industries. Our years of application experience assures that all elements of the design process are considered.
When the load is very big, the motor power will be also very large for single screw jacks and the safety factor is low and a guide rail is needed. The performance and components of the screw lift are very unfavorable. So more people tend to choose four linkages or six linkages, which perfectly solves the problem of too long span. At the same time, multiple linkages are relatively stable and have a high safety factor.
Now let's see a video about a 4-set screw jack system.
