Product Description
Product Introduction
A jack is a lightweight and compact lifting device used to raise heavy objects. Utilizing mechanical transmission or hydraulic principles, it provides essential lifting power for scenarios such as vehicle maintenance and equipment installation. The main product categories include:
1. Screw Jack
Features: Lifting achieved through the helical transmission mechanism of a screw and nut. Its core advantage lies in its strong self-locking capability, enabling safe and stable positioning at any height with robust load-bearing performance. However, the system suffers from lower efficiency and slower lifting speed.
Application: Suitable for tasks requiring prolonged support, such as construction projects and equipment positioning/installation.
2. Horizontal Jack
Features: Specifically designed for automotive maintenance, the tray can be placed horizontally, allowing easy access under the vehicle. Utilizing hydraulic principles, it offers a long stroke and a wide support range, making operation effortless.
Application: Almost standard equipment in automotive repair shops, used for lifting vehicle chassis.
3. Hydraulic Jack
Features: Utilizes Pascal's principle to transmit power via hydraulic oil. Its core advantages include immense lifting capacity, effortless operation, and smooth lifting motion. It must be used vertically, and long-term support requires the use of safety brackets for added stability.
Applications: Wide-ranging, from passenger car and heavy-duty truck maintenance to lifting industrial heavy equipment.
Summary of the core differences:
Spiral type: Mechanically self-locking, suitable for long-term support.
Horizontal vs. Hydraulic: Both belong to hydraulic transmission systems, but the horizontal type is specifically optimized for low-profile spaces such as under vehicle chassis, while the general-purpose hydraulic type focuses on achieving high tonnage capacity and versatility.
