Analysis of the lifting capacity and rotation radius of a pneumatic hoist during operation

1、 Lifting capacity range: covering light to heavy work requirements

The lifting capacity design of pneumatic hoists is flexible, and suitable models can be selected according to different scene requirements:

Lightweight applications

The minimum lifting capacity can reach 250 kilograms, suitable for light load scenarios such as precision instrument assembly and laboratory material handling.

Case: Korean KHC brand KA1S-025 pneumatic hoist, with a rated load of 250 kilograms and a lifting speed of 17 meters per minute, suitable for electronic manufacturing workshops.

Medium sized universal

The mainstream models have a lifting capacity of 2 tons to 10 tons, covering the conventional lifting needs in fields such as automobile manufacturing, logistics and warehousing, and ship repair.

Case: HQ2-6 pneumatic hoist, rated lifting capacity of 2 tons, lifting height of 3-16 meters, chain size of 8 × 24mm, weight of only 34 kilograms, easy to move and operate.

Heavy industry

The maximum lifting capacity can reach 30 tons, suitable for heavy-duty scenarios such as mining equipment hoisting and steel plant raw material handling.

Case: KA3M-3000 pneumatic hoist, rated load of 30 tons, lifting height of 36 meters, air consumption of 11.2 cubic meters per minute, meets the lifting needs of large workpieces.

Technical support:

The pneumatic hoist achieves low-speed high torque output through the combination of planetary reducer and pneumatic motor. For example, a 10 ton pneumatic hoist (such as HQ10-3) can stably lift heavy objects at a pressure of 0.6 MPa, and the gas cut-off protection device ensures that the heavy objects will not fall when the gas source is interrupted.

2、 Rotation radius: compatible with cantilever crane and guide rail moving system

The rotation radius of the pneumatic hoist depends on its installation method (cantilever crane or guide rail), which directly affects the scope and flexibility of the operation:

Cantilever crane configuration

Rotation radius range: usually 2 meters to 7.5 meters, depending on the model.

The cantilever length of a 2-ton pneumatic hoist (such as HQ2-6) can be customized to fit a rotation radius of 2-3 meters.

The cantilever length of a 10 ton pneumatic hoist (such as QH10) can reach 7.5 meters, which is suitable for cross regional operations in large workshops.

Advantages: The cantilever structure allows for 360 ° rotation, covering a large working area without the need to move the hoist body, improving efficiency.

Guide rail mobility configuration

Concept of rotation radius: Under the guide rail system, the pneumatic hoist moves along a linear guide rail, and the rotation radius can be regarded as "infinitely long" (limited only by the length of the guide rail).

Application scenario: In logistics and warehousing, the guide rail pneumatic hoist can move along the shelf track to achieve precise storage and retrieval of goods. The requirement for rotation radius is weakened, and more attention is paid to the accuracy of linear movement.

Compared to electric hoists:

The rotation radius of electric hoists is usually 1.5 to 7.5 meters (such as 2.5-5 meters for 5-ton electric hoists), but pneumatic hoists are smaller in size and lighter in weight (only 1/3 to 1/8 of electric hoists) under the same lifting capacity, so the cantilever configuration is more flexible and can adapt to more compact working spaces.

3、 Core advantage: synergistic effect of lifting capacity and rotation radius

Adaptability to explosion-proof environment

Pneumatic hoists have no electrical components, completely eliminating the risk of sparks, and can be safely used in flammable and explosive places such as petrochemicals and coal mines. For example, the use of pneumatic hoists in Shanxi Coking Coal Dongqu Mine has increased the efficiency of equipment replacement by 40% without any safety accidents.

Efficient homework ability

Lifting speed: The lifting speed of pneumatic hoists is three times that of electric hoists (such as HQ10-3 type lifting speed of 1 meter/minute, while electric hoists usually have a lifting speed of 0.3 meters/minute).

Positioning accuracy: Through air pressure stepless speed regulation, centimeter level precise positioning is achieved to meet the requirements of precision assembly.

Tolerance to harsh working conditions

Pneumatic hoists can operate stably in high temperature, humidity, and high dust environments above 60 ℃. For example, the shipbuilding industry uses pneumatic hoists to lift ship sections and adapt to high-altitude and narrow space operations.

Economic advantage

Maintenance cost: Pneumatic hoists have a simple structure and low component wear rate, saving about 15000 yuan in annual maintenance cost compared to electric hoists (taking medium-sized equipment as an example).

Energy consumption: Powered by compressed air, the energy cost is reduced by 20% -30% compared to electric hoists.
