The working principle of pneumatic crane is to use compressed air as the power source, and drive the monorail crane to carry items on the suspension track through the control system. Specifically, the working principle mainly includes the following aspects:
Power source: The power of the pneumatic crane comes from compressed air, which is different from traditional electric monorail cranes or other forms of monorail cranes. Due to the use of compressed air, it does not generate exhaust emissions and is suitable for environments with poor ventilation conditions, such as mining tunnels.
Control system: Modern pneumatic cranes typically use a handle control device, which allows operators to perform forward, backward, and braking operations through these control devices. There are three control modes: pneumatic wire control, wireless remote control, and both, which can adapt to different working environments and distance requirements.
Speed adjustment: In order to meet different usage needs, the pneumatic crane will adjust the speed provided by the pneumatic motor through a deceleration device to achieve the actual required transportation speed.
Structural composition: A typical pneumatic crane may include parts such as a load-bearing trolley, driving part, connecting assembly, auxiliary braking device, pneumatic control system, and pneumatic lifting hoist. The load-bearing car is responsible for carrying weight, the driving part provides power, the connecting assembly and connecting rod are responsible for effective connection between various components, the auxiliary braking device is used to enhance safety, and the pneumatic control system is responsible for controlling various commands.
Safety features: For safety reasons, the pneumatic crane is equipped with an accident prevention braking device, usually a spring clamped braking brake, which belongs to a fail safe design, ensuring that the brake is automatically activated in the event of insufficient air pressure to prevent accidents from occurring.
In summary, pneumatic cranes have gradually become an effective tool for material transportation under specific conditions due to their unique advantages, such as environmental friendliness and suitability for special environments. With the advancement of technology, the flexibility and reliability of its control system are constantly improving, making operation easier and safer.
