Stationary Crane Hoists: A Comprehensive Guide
Stationary crane hoists are essential lifting equipment used in various industries worldwide. From manufacturing plants to ports, these versatile machines enhance efficiency and safety in material handling. This guide delves into the intricacies of stationary crane hoists, exploring their technical aspects and diverse types. Companies like Henan Weihua Heavy Machinery Co., Ltd. (www.weihuacranegroup.com) are major players in the global crane hoist market, showcasing the scale of this industry.
Understanding Stationary Crane Hoists
Stationary crane hoists, unlike mobile cranes, are fixed in a specific location. They are typically attached to a structure, such as a ceiling, wall, or freestanding column. This fixed position allows for precise lifting and positioning within a defined workspace. Their robust design and high lifting capacity make them suitable for heavy-duty applications. Shenghua Crane Group (www.shenghuacranes.com) offers a wide range of these hoists, highlighting the variety available.
Technical Features Comparison
The performance of a stationary crane hoist depends on several key technical features. These features vary across models and manufacturers. The following table compares some essential specifications:
| Feature | Metric Unit | High-Capacity Model | Medium-Capacity Model | Low-Capacity Model |
|---|---|---|---|---|
| Lifting Capacity | Tonnes | 10-50 | 2-10 | 0.5-2 |
| Lifting Height | Metres | 10-30 | 5-15 | 2-8 |
| Hoist Speed | m/min | 5-20 | 2-10 | 1-5 |
| Motor Power | kW | 50-200 | 10-50 | 2-10 |
| Duty Cycle | % | 25-50 | 40-60 | 60-80 |
| Control Type | Pendant, Remote | Pendant, Remote | Pendant |
Note: These values are approximate and can vary based on the specific manufacturer and model.
Types of Stationary Crane Hoists
Stationary crane hoists are categorized based on their lifting mechanism, mounting type, and capacity. The following table highlights the key differences:
