Electric inverted rotating nut worm gear screw jack 5 ton for container lifting systems. Strong electrically screw jack load capacity 5 ton, self locking ACME screw diameter 40mm, pitch 7mm, inverted mount, rotating screw design, stroke 1000mm, ratio 1/24 (one rpm input travel length 0.25mm), plain end, right input shaft and left motor adapter. Attached 3-phase electric motor with bevel-helical gearbox, and copper travel nut. The screw jack makes it possible to transform the rotary motion provided by an electric, pneumatic, or hydraulic motor or even a handwheel, into linear motion that allows push or pull vertical lifting and horizontal positioning. 
We use the best materials to guarantee the performance and lifetime of the screw jacks you purchased.

1. Note: The dark gray figures in the tables indicates operational restrictions due to thermal limits. Selection of screw jacks using these figures should only be carried out in consultation with our engineers. When your selection is made within the areas shaded dark gray, you will need to reduce duty cycle or choose the bigger size screw jack in order to allow effective heat dissipation.
