Harrington Hoists (harringtonhoists.com) also offers related equipment.
Types and Technical Features of Running Beam Hoists
Running beam hoists, also known as beam trolleys, move along the lower flange of I-beams or H-beams. They are essential for material handling in various settings, from factories and warehouses to construction sites and mining operations. The choice between electric and manual operation depends on power availability and load requirements. Electric models offer ease of operation and higher efficiency for heavier loads, while manual models are suitable for situations lacking electrical power.
The following table compares the technical features of different running beam hoist types:
| Feature | Electric Chain Hoist Trolley | Manual Geared Trolley | Manual Plain Trolley |
|---|---|---|---|
| Power Source | Electric | Manual | Manual |
| Operation | Motorized | Geared | Plain |
| Speed | Variable, typically higher | Moderate | Low |
| Capacity | Varies (0.5t-20t+) | Varies (0.5t-5t) | Varies (0.5t-5t) |
| Maintenance | Moderate | Low | Very low |
| Cost | Higher | Moderate | Lower |
| Application | Heavy-duty lifting | Moderate-duty lifting | Light-duty lifting |
| Suitable for | Factories, warehouses | Workshops, construction | Limited power areas |
Differences in Types of Running Beam Hoists
Several types of running beam hoists are designed to optimize performance for specific applications. These differences are primarily in their design and mounting, influencing headroom requirements and load capacity.
This table compares the different types of running beam hoists:
| Type | Description | Advantages | Disadvantages |
|---|---|---|---|
| Standard Electric Overhead Crane | Runs on top of the I-beam or H-beam. | Simple design, widely available, easy maintenance. | Requires sufficient headroom. |
| Low Headroom Overhead Crane | Designed to minimize the vertical space needed, the hoist trolley runs below the main girder. | Maximizes headroom, ideal for low-ceiling environments. | More complex design, potentially higher cost. |
| Underslung Overhead Crane | The crane structure is mounted below the I-beam or H-beam. | Ideal for facilities without load-bearing columns but with load-bearing roofs, maximizes usable space. | Limited load capacity compared to other types, specific structural requirements. |
| FEM/DIN Standard Overhead Crane | Conforms to European standards, often featuring a compact three-in-one reducer for space efficiency and quiet operation. | Compact design, precise positioning, stepless speed regulation, low maintenance. | Higher initial cost. |
| Offset Trolley Overhead Crane | Trolley is offset from the center of the beam, allowing for increased lifting height in low headroom situations. | Maximizes lifting height in low-ceiling spaces. | More complex design, potential for increased sway. |
| Manual Overhead Crane | Operates without electricity, using manual power for movement. | Suitable for areas without electrical power, low maintenance. | Slower operation, limited capacity, physically demanding. |
Conclusion
Selecting the appropriate running beam hoist depends on several factors, including load capacity, headroom, power availability, and budget. By carefully considering these factors and comparing the various types and features available from manufacturers like Allman Lift, Hilifting, Wuyi Lifting, DG Crane, and Harrington Hoists, you can make an informed decision to optimize your material handling processes.
FAQs
1. What is the difference between top running and under running cranes?
Top running cranes travel on top of the I-beam, requiring more headroom. Under running cranes travel beneath the I-beam, maximizing headroom. The choice depends on available space and building structure.
2. What factors should I consider when choosing a running beam hoist supplier?
Consider the supplier’s experience, product range (including customization options), references, manufacturing facilities, after-sales support, and pricing. A reputable supplier ensures product quality and reliable service.
3. What are the safety considerations when using running beam hoists?
Regular inspections, proper training for operators, adherence to load limits, and the use of safety devices (e.g., overload protection) are crucial for safe operation.
4. How do I calculate the required capacity for a running beam hoist?
The capacity needs to exceed the weight of the heaviest load to be lifted, with a safety factor considered. Consult load charts and engineering specifications to ensure proper selection.
5. What is the typical lifespan of a running beam hoist?
Lifespan varies depending on usage, maintenance, and environmental conditions. Proper maintenance can significantly extend the operational life, potentially for many years.
