High Lift Screw Jack

Long - stroke Design: It has an extremely long screw rod, which can achieve a much larger lifting stroke than ordinary screw jacks, meeting the demand for lifting heavy objects in high - space environments. For example, in tall building construction, it is used for the high - altitude transportation of building materials, or in the installation of large - scale mechanical equipment, it is used for the vertical height adjustment of the equipment.

High - strength Screw Rod Material: The screw rod is made of special high - strength alloy steel. It can not only withstand huge axial pressure but also has excellent fatigue resistance, ensuring that it will not deform or break during frequent high - lift operations, and guaranteeing the long - term stable operation of the equipment.

Gradual Lifting and Lowering Control: Through the precise thread design, a smooth and precisely controllable gradual lifting and lowering action is achieved. Operators can adjust the rising or falling speed of heavy objects slowly and evenly according to actual needs, facilitating precise operation in work with high precision requirements, such as the installation and positioning of large - scale sculptures.

Stable Base Structure: It is equipped with a wide and heavy base, which increases the contact area with the support surface and effectively disperses the pressure generated by lifting heavy objects at high lift. It improves the stability of the entire jack during the working process and reduces the risk of tipping over. Even on uneven ground, it can maintain a good support state.

Self - locking and Anti - reverse Mechanism: It has a built - in reliable self - locking device. When the screw rod stops rotating after rising to the 预定 height, it can automatically lock to prevent the screw rod from reversing and the heavy object from sliding down due to the self - weight of the heavy object or external vibration. At the same time, a special anti - reverse mechanism is set up to further enhance the safety and reliability of the equipment in the bearing state.

Meet the Needs of High - altitude Operations: The long - stroke design enables it to easily cope with high - altitude operation scenarios, providing a reliable solution for lifting heavy objects in large - scale construction, bridge construction, and large - scale equipment installation, solving the height limitation problem that ordinary jacks cannot reach.

Ensure Safe and Reliable Work: High - strength screw rod materials, stable base structures, and perfect self - locking and anti - reverse mechanisms comprehensively ensure the safety during the process of lifting heavy objects at high lift. It effectively prevents safety accidents such as heavy object falling caused by equipment failures or improper operations, providing reliable safety protection for operators and the surrounding environment.

Achieve Precise Operation: The characteristics of gradual lifting and lowering control and highly visual operation enable precise control of the lifting height of heavy objects in work with extremely high requirements for height accuracy, such as the installation of precision instruments and the arrangement of artworks. It improves work quality and efficiency and reduces rework and losses caused by inaccurate positioning.

Highly Visual Operation: Clear scale markings are set on the screw rod or the main body of the jack. Operators can intuitively understand the current lifting height of the heavy object, which is convenient for precisely controlling the lifting height and ensuring the accuracy of work. At the same time, some models may also be equipped with a height display instrument to further improve the accuracy and readability of height display.

Reduce Labor Intensity: In the electric - drive mode, operators only need to control the buttons to complete the lifting and lowering operation of heavy objects, without the need for heavy physical labor like traditional manual jacks. It greatly reduces labor intensity, reduces manual fatigue, and also reduces the risk of operation errors caused by manual fatigue.
