| Power Source | Electric Motor | Compressed Air | Manual (Hand-Powered) |
| Lifting Capacity | Up to 100 tons | Up to 100 tons | Up to 50 tons |
| Duty Cycle | Limited (requires rest) | Continuous operation | Intermittent use |
| Speed | High | Moderate | Low |
| Control | Pushbutton or remote | Pneumatic controls | Hand-operated |
| Maintenance | Moderate | Low | Low |
| Noise Level | Moderate | Low | High |
| Ideal Use | Industrial applications | Heavy-duty environments | Occasional lifting |
Types of Overhead Hoists
Overhead hoists can be categorized based on their lifting medium and power source. The following table summarizes the different types of overhead hoists and their characteristics:
| Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| Chain Hoists | Use a chain and pulley system for lifting. | Economical, portable, low maintenance | Limited lifting speed, lower capacity |
| Wire Rope Hoists | Utilize wire rope wrapped around a drum for lifting. | Higher lifting capacity, smoother operation | More expensive, requires more space |
| Electric Hoists | Powered by electric motors for efficient lifting. | High speed, easy to control | Limited duty cycle, requires electrical supply |
| Pneumatic Hoists | Operated by compressed air, ideal for continuous use. | Can run continuously, low risk of overheating | Requires air supply, less portable |
| Manual Hoists | Hand-operated hoists for occasional lifting tasks. | Simple design, no power source needed | Slower operation, requires physical effort |
