  • Automotive Industry

    In the automotive industry, screw jack car lifts are used to lift vehicles for repairs, maintenance, and inspections. Due to their high load capacity, stability, and ease of operation, they are preferred over other types of jacks.

  • Construction Industry

    In the construction industry, screw jack car lifts are used to lift heavy materials and equipment to different heights. They are also used in scaffolding systems to provide support and stability.

  • Mining Industry

    In the mining industry, screw jack car lifts are used to lift heavy equipment and machinery to different levels. They are preferred over other types of jacks due to their safety and stability features.

  • Transportation Industry

    In the transportation industry, screw jack car lifts are used to lift and level railway tracks, bridges, and other structures. They are also used to lift and lower shipping containers.

What is the working principle of screw jack?

A screw jack car lift consists of a screw mechanism and a lifting platform. The screw mechanism includes a worm gear, a worm, and a lifting screw. When the worm gear is rotated, it turns the worm, which rotates the lifting screw. The lifting screw then moves up or down, depending on the direction of rotation, and lifts or lowers the lifting platform.

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

The main difference between a screw jack and a hydraulic jack is the way they lift heavy loads. Screw jacks use a screw mechanism to lift loads, while hydraulic jacks use hydraulic fluid to lift loads. Screw jacks are preferred for heavy loads due to their stability, safety features, and ease of use, while hydraulic jacks are preferred for lighter loads due to their speed and precision.

How to select or customize the right screw jack?

  • Load Capacity

    The load capacity of the screw jack should be selected based on the weight of the load to be lifted. It is important to factor in the weight of the lifting platform as well.

  • Lift Height

    The lift height required depends on the application. It is important to select a screw jack that can lift the load to the required height.

  • Screw Lead

    The screw lead determines the speed of the screw jack. A larger screw lead means faster lifting speed, but lower load capacity.

  • Operating Conditions

    The operating conditions, such as temperature, humidity, and corrosiveness, should be considered when selecting a screw jack. It is important to choose a screw jack that is suitable for the specific operating environment.

  • Customization

    If the standard screw jacks do not meet the requirements, customization is possible. This includes modifying the lift height, load capacity, and screw lead, among other features.
