MOM mechanical jacks can be used for different applications, for example to lift, pull and move. In addition, when applied in series connected by shafts, couplings, and bevel gearboxes, they allow to align any traslating mass with synchronism. They are irreversible, suitable to support the apply loads without necessity used the brakes or others block systems. The standard supplies are foresee with steel or stainless steel trapezoidal screw. On request they can be supplied with ball screws. In addition to TS models (translating screw) and RS models (rotating screw) are predict the electric cylinder MET/MES to special executions.For all executions are foresee a standard and special range accessories to end of the threaded shaft, to protect the screw from debris through rigid and flexible protection and motors mount accessories. We can supply special motor mount to direct mount of hydraulic motors, pneumatic motors, brushless, dc motors and other special motors. If necessary we can realized the attack with motor mount and coupling
