SWL-5T Worm Gear Screw Lift

5-Tonne Mechanical Linear Actuator for Precision Lifting & Positioning

The SWL-5T Worm Gear Screw Lift is a compact, heavy-duty mechanical actuator designed for controlled vertical lifting, lowering, positioning, and load holding in industrial environments. Rated for up to 1,000 kg working load, it combines a worm gearbox with a trapezoidal lead screw to deliver smooth linear motion with excellent positional stability.

Unlike hydraulic systems, the SWL-5T provides precise mechanical control without fluid power, making it ideal for applications requiring accuracy, reliability, and low maintenance.

Constructed with a cast-iron housing, copper worm wheel, and hardened steel worm shaft, this unit is engineered for long service life under continuous or intermittent duty.

It can be operated via electric motor or manual handwheel and may be used individually or synchronised in multi-jack lifting systems.

Load Capacity (SWL-5T)

• Rated working load: 500–1,000 kg

• Screw size: Tr40 × 7 mm trapezoidal thread

• Input speed: 1400 rpm

• Typical output speed: ~186 rpm

• Output torque range: 8.86–464 Nm

Designed for accurate height control and stable load retention.

Key Features

• Self-locking worm gear design
  Prevents back-driving under load, maintaining position without additional braking.

• High-strength construction
  Cast iron gearbox (HT250), copper worm wheel (94%), and C45 steel worm ensure durability.

• Selectable reduction ratios
  Available in 6:1 / 12:1 / 24:1, allowing optimisation between speed and lifting force.

• Motor or manual operation
  Compatible with 0.75–1.5 kW motors, or supplied with handwheel for manual adjustment.

• Customisable stroke length
  Standard screw length: 500 mm
  Longer strokes available on request.

• OEM configuration available
  Custom mounting styles, screw types, anti-rotation guides, motors, covers, and accessories.
