Pneumatic jack is a lifting device powered by compressed gas, widely used in mobile lifting scenarios such as automobile maintenance and heavy vehicle inspection.
It achieves smooth lifting through airbag or hydraulic cylinder structure, and has the characteristics of small size, light weight, and easy operation.
Working principle and structure
Pneumatic jacks are usually driven by compressed air, and their core structure includes airbag components or pneumatic hydraulic systems.
For example, the airbag design uses multiple layers of rubber airbags to inflate and lift under a pressure of 5-8kg, while the pneumatic hydraulic type combines gas power and liquid pressurization technology to achieve lifting through hydraulic cylinders.
Two models are equipped with a three-point support system, which can adapt to uneven ground.
Main Features
Efficient and safe: The lifting process is fast (such as a sedan lifting for about 3 seconds), the soft contact surface avoids damaging the vehicle chassis, and there is no risk of hydraulic oil leakage.
Strong adaptability: It can operate in low temperatures (as low as -40 ℃) or complex terrains such as sand and snow, and some models support tilt angle adjustment.
Durable and low maintenance: The pure pneumatic structure reduces seal wear, resulting in lower long-term usage costs.
