Single Beam Electric Chain Hoist Lifting Hoist For Bridge Crane
The single - beam electric chain hoist is a crucial lifting device specifically designed for use with bridge cranes. It combines the advantages of compact structure, high efficiency, and reliable operation, making it an indispensable component in various industrial settings where heavy - duty lifting and material handling are required.
- Product Introduction
Configuration Options
| Installation Type | Trolley-mounted electric chain hoist for a single beam or monorail |
| Rated Capacity | Selected according to the load, duty class and lifting conditions |
| Lifting Height | Standard or customized chain length |
| Lifting Speed | Single-speed, dual-speed or project-specific control |
| Trolley Drive | Manual push, geared travel or motor-driven trolley |
| Power Supply | Voltage, frequency and phase configured for the destination market |
| Control Method | Pendant station, wireless remote or integrated crane control |
The hoist and trolley should be selected together with the supporting beam. Capacity alone is not sufficient: beam flange width, wheel profile, headroom, travel distance and operating frequency must also be checked before production.
Main Assembly
| Component | Function | Selection Point |
|---|---|---|
| Hoisting motor | Provides power for raising and lowering | Capacity, speed, duty and power supply |
| Gear transmission | Transfers motor torque to the chain wheel | Reduction ratio and service classification |
| Load chain | Carries the hook assembly and suspended load | Chain size, chain falls and required lift |
| Bottom hook | Connects the load through approved rigging | Hook opening, latch and swivel arrangement |
| Travel trolley | Moves the hoist along the supporting beam | Beam flange, wheel spacing and travel speed |
| Chain container | Collects the unloaded section of lifting chain | Chain length and available installation space |
Single-Beam Matching Data
Correct trolley matching keeps the wheels seated properly on the beam flange and helps prevent excessive flange contact, unstable travel or uneven wheel loading. The following dimensions should be reviewed before the hoist is released for production.
| Beam Profile | I-beam, monorail or project-specific runway section |
| Flange Width | Minimum and maximum width along the complete travel path |
| Flange Thickness | Required for wheel position and trolley adjustment |
| Runway Shape | Straight beam or curved monorail section |
| Available Headroom | Vertical distance between the beam and required hook position |
| Travel Distance | Used to plan power supply and control arrangements |
Safety and Control Options
| Available Feature | Purpose |
|---|---|
| Upper and lower limit control | Restricts hook travel at the preset lifting boundaries |
| Overload limiting device | Helps prevent lifting above the configured operating limit |
| Motor brake | Controls and holds the lifting movement when power is removed |
| Emergency-stop control | Allows the operator to stop powered motion when necessary |
| Phase protection | Protects suitable three-phase systems from incorrect phase conditions |
| Wireless control | Provides an alternative operating position where approved |
The final safety arrangement depends on the hoist model, local requirements and the customer's control system. Required devices and control functions should be listed in the inquiry rather than assumed to be included as standard.
Suitable Working Areas
- Assembly and maintenance stations in manufacturing plants
- Warehouse loading and internal material transfer
- Single-girder crane and fixed monorail systems
- Machine installation and component positioning
- Workshops with restricted floor space
- Production lines requiring repeated point-to-point lifting
Inspection Before Delivery
| Configuration Check | Capacity, lifting height, speed, voltage and trolley range |
| Appearance Inspection | Housing, chain, hook, latch, cables and surface finish |
| Operating Check | Lifting, lowering, braking and trolley movement |
| Control Check | Pendant functions, travel direction and installed protective devices |
| Documentation | Configured data, inspection records and manuals according to the order |
Information Required for Quotation
- Maximum load and required lifting height
- Single-speed or dual-speed lifting requirement
- Manual, geared or electric trolley
- Beam profile, flange width and flange thickness
- Power supply and control voltage
- Travel distance and working frequency
- Indoor, outdoor, humid or corrosive environment
- Required protective devices and inspection documents
The supporting beam and crane structure must be verified separately for the imposed wheel loads and operating forces. Installation, commissioning and maintenance should be performed by qualified lifting-equipment personnel.
Compare this configuration with a beam-trolley electric chain hoist, low-headroom chain hoist or an electric chain hoist with overload limiter.
Send the load, lifting height, beam dimensions and power-supply details for model selection and quotation.
