Mechanical Screw Jack Double Lift SURYA

A Screw Jack Double Lift is a mechanical device designed to lift, position, or support heavy loads using the principle of a screw thread. Unlike a single lift screw jack, the double lift model incorporates two lifting screws arranged in a telescopic or compound configuration. This design provides a greater lifting height without increasing the overall length of the screw, making it highly efficient where space constraints exist.

The double lift screw jack typically consists of:

• Base frame or housing – provides stability and supports the screw mechanism.

• Two screw shafts – one outer screw and one inner screw, moving telescopically to achieve extended lift.

• Worm gear or bevel gear drive – converts rotational input into linear motion.

• Load-bearing nut or saddle – supports the load during lifting.

Key Features:

• Compact design with high lifting range.

• Self-locking capability in most designs, ensuring safety without external braking.

• Can be operated manually (using a handle) or mechanically (with motor or gearbox).

• Suitable for applications requiring precise lifting and positioning of heavy machinery, platforms, or structures.

Applications:

• Industrial machinery lifting

• Maintenance and repair work

• Stage/platform elevation

• Construction equipment

• Material handling systems
