Four Screw Jacks Systems Arrangement

Four Screw Jacks Systems Arrangement, also named A four point lift system that was devised using four screw jacks, bevel gearboxes, couplings and drive shafts. Complete Screw Jack System and lifting platfrom can be built in many formats, such as vertical lifting, pull or push, or horizontal positioning. There are no "standard" travel lengths and all screw jack systems are built to specification. In applications in which either multiple machine screw jacks or ball screw jacks are configured in a lifting system, a single motor could drive all screwjacks, further improving energy efficiency. Whether you need to adjust the height of a conveyor system or position a piece of equipment, we offer a range of screw jacks to suit your need. Can customize jacking systems to your specifications.

Worm gear screw jack systems are perfect for lifting, lowering, and push or pull movements. The most popular system configurations are the "H",  "U",  "T",  "TT",  "HI" and  "UI" configured 4-jack systems. Note that multiple screw jacks can be linked together mechanically or electrically. Where there are multiple jacks forming part of a complete system, calculate the total input power for the system, including losses in couplings and gear boxes, using the following efficiency: 4-jacks system 85%, bevel gearboxes efficiency 94%. If motorized screw jack system, the bevel-helical gear motors efficiency 90%-95%, but RV worm gear motors efficiency 40%-50%.
