1. Electric Trolleys: The Overhead Mobility Solution
Electric trolleys are motorized carriers that move along overhead beams (I-beam or H-beam tracks), providing horizontal transportation for suspended loads. Unlike manual pusher trolleys, electric models feature:
Drive Systems: Geared motors (0.5-5 kW) with VFD control for smooth starts/stops
Wheel Configurations: 4-wheel (standard) or 8-wheel (heavy-duty) designs
Control Options: Pendant stations, radio remotes (300m range), or automation-ready PLC interfaces
Capacity Range: 250 kg to 32 tons for single-girder systems
Critical Specs:
| Feature | Standard | Heavy-Duty |
|------------------|-------------------|-------------------|
| Travel Speed | 8-20 m/min | 5-15 m/min |
| Beam Width | 75-300 mm | 300-600 mm |
| Duty Class | CMAA Class B | CMAA Class D |
| IP Rating | IP54 | IP65 |2. Electric Hoist with Trolley: Integrated Vertical-Horizontal Movement
When paired with a trolley, electric chain hoists transform into complete overhead handling systems:
Key Integration Benefits:
Unified Controls: Single pendant operates both lift and travel functions
Optimized Footprint: Eliminates floor obstructions – ideal for narrow aisles
Precision Handling: Positioning accuracy ±1 mm with encoder feedback
Safety Synergy: Coordinated brakes prevent load swing
Top Applications:
Assembly Line Transfer: Move engines between stations (automotive)
Warehouse Order Picking: Retrieve pallets in high-bay storage
Maintenance Bays: Position heavy machinery components

Pre-matched hoist and trolley packages solve compatibility issues while offering:
Advantages Over Piecemeal Systems:
Guaranteed load capacity matching (no derating calculations)
Pre-tested control interfaces
Unified warranty coverage
30% faster installation (pre-drilled mounting points)
Industry-Leading Configurations:
| Package Type | Capacity | Travel Speed | Ideal For | Price Range |
|---|---|---|---|---|
| Compact | 250-500kg | 10 m/min | Workshops, Garages | $1,200-$2,500 |
| Industrial | 1-5 ton | 15 m/min | Factories, Warehouses | $3,800-$12,000 |
| Foundry Grade | 10-32 ton | 8 m/min | Steel Mills, Heavy Fabrication | $18,000-$55,000 |
