Pneumatic (Air) Chain Hoists: Ideal for Explosion-Proof Environments
A pneumatic motor drives the pneumatic (air) chain hoists to operate the lifting and lowering functions, with compressed air as the primary power source. This equipment is typically suitable for environments with high explosion-proof requirements, especially in locations where combustible gases or dust are present, such as chemical plants, oil fields, and mines.
Features of Pneumatic (Air) Chain Hoists:
- Excellent Explosion-Proof Performance: Pneumatic (air) chain hoists do not generate electric sparks, making them suitable for flammable and explosive environments.
- No Overload Risk: Due to the characteristics of the pneumatic system, when the load exceeds the rated value, the pneumatic (air) chain hoists automatically stop running instead of causing motor burnout like electric hoists.
- High-Frequency Operation Capability: Pneumatic (air) chain hoists can operate continuously in high-frequency work environments without overheating, making them especially suitable for assembly lines and continuous production processes.
- Flexible Operation: The control of pneumatic (air) chain hoists is usually simple and responsive, allowing for precise load positioning.
- Compact and Lightweight: Due to the simple structure of the pneumatic motor, pneumatic (air) chain hoists are typically lightweight, making them easy to install and move.
- Low Maintenance Costs: The simple design of pneumatic (air) chain hoists makes them easy to maintain, with fewer electrical components and lower failure rates.
- Wide Temperature Range: Pneumatic (air) chain hoists can operate across a broad temperature range, maintaining stable performance even in extreme conditions.
