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, allowing it to safely stop at any position while maintaining stable load-bearing capacity. However, its efficiency is relatively low, resulting in slower lifting speeds.
Application: Suitable for operations 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: Utilizing Pascal's principle, power is transmitted via hydraulic oil. The core advantages include immense lifting capacity, effortless operation, and smooth, stable lifting. It must be used in a vertical orientation, and for long-term support, it should be paired with a safety bracket.
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 universal hydraulic type focuses on achieving high tonnage capacity and broad applicability.
