Automatic and permanent nut lubrication system to guarantee efficient lubrication during lifting and descent.
Main nut made of bronze (no plastic) with high resistance to wear, for greater safety.
Steel high resistance rolled screws, to provide long life.
Tubular structure made of 5 robot welded sections, nothing sturdier in the world.
The carriage driven by 10 low friction slides on the post external part assure equilibrated and steady lifting also in case of asymmetric loading and prevent transmission of flexion to the spindles and the nuts, granting long life.
Specially manufactured motors fitted with overheating protection switch.
Automatic arm locking during lifting and automatic unlocking when the arm reaches the floor – self-locking conical design.
