Rotating Screw Mechanical Jacks: Precision and Power in Lifting
The rotating screw mechanical jacks (HR Series) represent a premier solution for linear motion in industrial environments. In this configuration, the rotary motion provided by the gearbox is converted into linear movement by the nut, ensuring maximum stability and pinpoint accuracy when positioning heavy loads.
Technical Specifications and Performance
Our range of mechanical screw jacks is engineered to cover a vast array of applications, featuring high-profile technical data:
-
Available Sizes: 6 distinct sizes for optimal dimensioning.
-
Maximum Force: From 5 kN up to 200 kN, ideal for heavy-duty lifting.
-
Reduction Ratios: Available in 1:4, 1:10, 1:16, and 1:30 configurations.
-
Trapezoidal Screws: Dimensions ranging from 18 x 4 to 70 x 10.
-
VRS Ball Screws: For high-efficiency applications, from 16 x 5 to 63 x 10.
Construction and Operation (HR Series)
The rotating screw jack system is based on an integrated worm gear and helical wheel unit, paired with either a trapezoidal threaded stem or a ball screw.
-
Lubrication: Grease-lubricated system for reduced maintenance and long component life.
-
Intermittent Duty: Designed for standard duty cycles, ensuring consistent reliability.
-
VRS Version: The availability of ball screws allows for higher speeds and lower friction compared to traditional trapezoidal screws.
Motorization and Control Options
To adapt to any electrical grid and automation requirement, our mechanical jacks support various AC motorizations:
-
Three-phase and Single-phase: Standard industrial or domestic power supply (230V/400V).
-
Brake Motors: Equipped with electromagnetic brakes for millimetric stopping precision.
-
Special Configurations: Single-phase versions with electronic capacitors, ideal for high starting torques.
Why choose the brake motor version? In rotating screw mechanical jacks, the parking brake is essential for ensuring repeatability of the stopping position during ON/OFF operation. Furthermore, it is indispensable for holding the load in position in reversible configurations (especially with ball screws), preventing accidental drifts.
