motorized worm screw jack lift device non-hydraulic heights adjustment for wind turbine tower raising systems

Motorized screw jack can also be called Electric screw jack, which includes a worm gear screw jack and an electric motor. The Motorized Jacks have higher efficiency than manual screw jack. There are two types worm gear screw jack for motorized screw jacks, they are self-locking machine screw jack or high precision ball screw jack. The motor can be a high-precision servomotor, stepping motor, geared motor, worm gear reducer, bevel helical gearmotor, worm helical gearmotor, three-phase motor, or single phase motor, and 12v, 24v, 48v Brush or Brushless DC motors and DC gear motors, etc. Note: If it is a electric ball screw jack, a brake motor or an external locking device is required to maintain the position. Electric screw jacks offer the most economic solutions for a wide range of industrial applications and the load capacity up to 100-ton as standard.
