1. Lifting heavy loads: Screw jacks are commonly used in industrial settings to lift heavy loads, such as machinery or equipment.
2. Positioning and leveling: Screw jacks provide precise control for positioning and leveling applications, ensuring accuracy and stability.
3. Mechanical adjustments: Screw jacks are used for making mechanical adjustments in various systems, such as adjusting the height of workbenches or conveyor systems.
4. Load-bearing support: Screw jacks can be used as load-bearing support in structures, providing stability and safety.
5. Maintenance and repair: Screw jacks are essential tools for maintenance and repair tasks, allowing workers to safely access and work on elevated areas or equipment.

What is the working principle of screw jack?

screw jack

The working principle of a screw jack is based on the mechanical advantage achieved by converting rotary motion into linear motion. It consists of a central screw shaft and a nut that moves along the shaft when rotated. As the nut moves, it raises or lowers the load attached to it. The thread pitch of the screw determines the distance traveled by the load for each revolution of the screw. This mechanism allows for precise and controlled lifting or lowering of heavy loads.

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

The main difference between a screw jack and a hydraulic jack lies in the method used to generate the lifting force. While a screw jack relies on mechanical force and rotational motion, a hydraulic jack utilizes fluid pressure to generate the lifting force. Hydraulic jacks are generally more powerful and capable of lifting heavier loads, while screw jacks provide better precision and control.

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:

1. Load capacity: Determine the maximum weight the screw jack needs to lift and select a suitable load capacity accordingly.
2. Travel distance: Calculate the required travel distance for the application and choose a screw jack with a corresponding stroke length.
3. Speed and efficiency: Consider the desired lifting speed and efficiency requirements to select the appropriate gear ratio or motor speed.
4. Environmental factors: Take into account the operating environment, including temperature, humidity, and exposure to corrosive substances, to choose a screw jack with appropriate protective measures.
5. Mounting and integration: Evaluate the available space and mounting options to ensure compatibility and ease of installation.
