Screw Jack for Monument Installation

A screw jack is a mechanical device used for lifting and positioning heavy loads, making it an essential tool for monument installation. With its unique design and capabilities, a screw jack provides precise control and stability during the lifting process.

1. What is a screw jack used for?

A screw jack is primarily used for lifting and supporting heavy structures, such as monuments, bridges, and machinery. It provides a reliable and steady lifting force, allowing for accurate positioning and alignment during installation.

2. What is the working principle of screw jack?

The working principle of a screw jack involves the conversion of rotational motion into linear motion using a screw thread. As the screw is rotated, it moves through a threaded nut, causing linear displacement and lifting or lowering of the load. This mechanical advantage enables the screw jack to lift heavy loads with relatively low input force.

3. What is the difference between a screw jack and a hydraulic jack?

Unlike hydraulic jacks that utilize fluid pressure, screw jacks rely on mechanical force to lift and hold loads. Hydraulic jacks are often used for rapid lifting and require a hydraulic power source, while screw jacks offer precise control and do not rely on external power.

4. How to choose or customize the right screw jack?

When selecting or customizing a screw jack, several parameters and practical conditions need to be considered:

  • Load capacity: Determine the maximum weight the screw jack needs to lift and ensure it is within the jack’s capacity.
  • Travel distance: Measure the required vertical travel distance and choose a screw jack with suitable stroke length.
  • Speed: Consider the desired lifting speed and select a screw jack with an appropriate gear ratio.
  • Environment: Evaluate the environmental conditions, such as temperature, humidity, and corrosive factors, to ensure the screw jack’s materials can withstand the surroundings.
  • Safety features: Look for screw jacks that have built-in safety mechanisms, such as overload protection and emergency braking systems, to ensure operator safety.
