Trolley Type Air Hoist

The trolley type air hoist is a lifting device powered by compressed air, with the core feature of mobility. It integrates a traveling trolley and can move laterally along preset paths such as I-beam tracks or cantilever crane tracks, while maintaining independent lifting and lowering functions. This traveling mode is achieved through a pneumatic control system. The operator can control the hoist's lifting and lowering actions as well as the trolley's running direction and speed by adjusting the air source input and output through buttons on the handle or pneumatic control valves, which drive the pneumatic motor and gearbox. The main advantage of the traveling pneumatic hoist lies in its combination of explosion-proof characteristics and mobility, making it suitable for scenarios where heavy objects need to be frequently moved, and there is a risk of flammable and explosive substances, such as in the chemical, petroleum, and shipbuilding industries. Besides the running type pneumatic hoists, we also have other air hoist types for sale.

Specifications

Advantages

Its core benefits include high-speed operation, precise control, safety and reliability, strong environmental adaptability, and easy maintenance, etc. The details below are for your reference: 

1. High-speed efficiency and precise control: The running speed of the running-type pneumatic hoist can reach three times that of an electric hoist and supports stepless speed regulation, allowing for flexible adjustment of the running speed. At the same time, its positioning accuracy can reach the centimeter level, avoiding the problem of inaccurate positioning of ordinary lifting equipment, and it is particularly suitable for scenarios requiring precise operation.

2. Safety and reliability with overload protection: Using compressed air as the power source, it fundamentally eliminates the risks of electrical fires and electric sparks, making it suitable for flammable and explosive environments. The equipment is equipped with overload protection and air cut-off protection functions. When the load exceeds the limit, it automatically stops working, and when the air supply is cut off, it can reliably brake to prevent the accidental drop of heavy objects.

3. Environmental adaptability and explosion-proof performance: It does not require electrical power and can operate stably in harsh conditions such as high humidity, high dust, high temperature, or corrosive environments. Its explosion-proof feature makes it widely used in industries with high safety requirements, such as chemical, shipbuilding, and mining.

4. Simple maintenance and structural advantages: The structure is compact, with a low component wear rate, and the maintenance process is simple and quick, reducing the cost of later maintenance. Some models use lightweight materials (such as aluminum alloy shells), further enhancing the convenience of handling.

What Is It Used For?

The specific application details of trolley type air hoists are as follows: 

1. Explosion-proof and safe operation: Due to the use of compressed air drive, it does not produce sparks or electric arcs, making it particularly suitable for flammable and explosive environments such as oil, chemical, coal mine, textile, and spray painting, effectively reducing the risk of fire and explosion.

2. High-efficiency lifting and handling: In industries such as automotive manufacturing, mechanical processing, and warehousing logistics, it can quickly lift large components or goods, ensuring smooth and precise lifting and improving production efficiency.

3. Adaptability to harsh environments: It can operate stably in high-temperature, high-dust, humid, or highly corrosive places such as mines, docks, steel mills, without the need for electrical power, avoiding equipment damage or safety accidents.

4. Flexible movement and positioning: By combining with cantilever cranes, tracks, or hand carts driven by pneumatic motors, it can achieve horizontal movement and precise positioning of workpieces. Suitable for temporary operations on production lines or complex space operations.

Trolley Type Air Hoist vs. Fixed Type Air Hoist: What Is the Difference? 

The fixed and running pneumatic hoists have differences in their operation methods, structural configurations, and application scenarios. Please keep reading to know more.

1. Operation Method

Fixed type pneumatic hoists are typically fixed in a specific position through hooks or similar means, capable only of vertical lifting and lowering of heavy objects without horizontal movement. Their structure is relatively simple, usually equipped with two button handles, and they are suitable for lifting tasks where the working position is fixed.

2. Structural Configuration

Running pneumatic hoists are equipped with pneumatic trolleys or running devices, which can be installed on I-beam tracks or cantilever crane tracks, allowing for horizontal movement left and right while maintaining vertical lifting capabilities. This design makes their operation more flexible, and they are typically equipped with four-button handles to control lifting and movement actions.

3. Application Scenarios

In terms of application scenarios, fixed pneumatic hoists are suitable for situations where the lifting point is fixed and frequent movement is not required, such as fixed-point assembly or fixed work station operations; while running pneumatic hoists are more suitable for scenarios where heavy objects need to be moved over a large range, such as material handling on production lines or flexible hoisting in warehouses.

In conclusion, if you only need vertical lifting without horizontal movement and the working position is fixed, and you are looking for a low-cost and highly stable solution, we recommend using a fixed pneumatic hoist. However, if you need to cover multiple workstations or perform long-distance material handling, we recommend using a running pneumatic hoist.
