Lift Master ​Trapezoidal Thread Type

Lift Master
  • ​Cantilever electric lifter using Trapezoidal Screw
  • ・Self-locking
    Trapezoidal Screw are mathematically self-locking and can be expected to hold loads.
    The motor needs a brake mechanism because vibrations and shocks can cause the self-locking mechanism to become ineffective.
    Our standard products use brake motors.
  • Economical
    It is more economical than Ball screw type. Taking advantage of the sliding contact Trapezoidal Screw, it is suitable for low speed, low frequency applications.
