| Chain hoist main parameters | ||
| Parameter Category | Specific Parameter Item | Description |
| Lifting capacity | Rated lifting capacity | 500 kg, 1 ton, 2 tons, 3 tons, 5 tons, 10 tons, etc. |
| Working class | Typically M3 or M4 (according to FEM/ISO standards) | |
| Lifting mechanism | Lifting height (H) | Standard: 3m, 6m, 9m, 12m; higher sizes (e.g., 18m, 24m) are available upon request. |
| Lifting speed (Vh) | Single speed: 4, 5, 8, 10 m/min, etc. | |
| Dual speed: Normal/micro speed (e.g., 8/2 m/min or 4/1 m/min) | ||
| Lifting chain | Type: Alloy steel high-strength lifting chain (e.g., G80 grade) | |
| Number of chains: 1 chain (small tonnage), 2 chains, 4 chains (large tonnage) | ||
| Lubrication: Galvanized or blackened, some with a lubricating oil layer | ||
| Motor and power supply | Motor type | Three-phase asynchronous motor, single-phase capacitor motor (small tonnage) |
| Rated voltage/frequency | Three-phase: 380V / 50Hz (industrial standard) | |
| Single-phase: 220V / 50Hz (household or light industrial) | ||
| Other voltages available upon request: 440V, 660V, 60Hz, etc. | ||
| Motor protection | Overload protector (integrated into the motor) | |
| Control system | Operating mode | Low-voltage handle control (24V/42V safety voltage, with emergency stop button) |
| Remote control (wireless/wired) | ||
| Operator cab (for large tonnage or specific working conditions) | ||
| Safety devices | Limit devices | Upper limit: Mechanical/electronic dual limit, automatic power cut-off |
| Lower limit: Electronic limit (optional) | ||
| Overload protection | Mechanical friction clutch to prevent overload damage | |
| Phase protection | Prevents motor reverse rotation due to incorrect power phase sequence or power failure (three-phase motor type) | |
| Brake system | Electro-disc brake or conical rotor brake, automatic braking upon power failure | |
| trolley parameters | ||
| Operation mode | Drive Type | Manual trolley: Manually pulled by a chain or directly pushed. |
| Electric trolley: Driven by an independent motor, operated by a handle or remote control. | ||
| Electric trolley drive | Operating Speed (Vt) | Speed: 10 m/min, 20 m/min, 30 m/min, etc. (single or dual speed) |
| Motor Power | 0.2 kW - 0.75 kW (depending on hoist tonnage and speed) | |
| Track adaptation | I-Beam Type | Compatible with standard I-beams such as I16, I20, I22, I25, I28, I32, and I36, depending on hoist tonnage and span. |
| Clearly specified dimensions are required, and the trolley rollers are usually adjustable to accommodate track width tolerances. | ||
| Minimum Turning Radius | For curved or circular tracks, the minimum allowable radius of curvature for the trolley must be specifically specified. | |
| Structure | Connection Method | Suspended type: Hoist suspended below the trolley (most common). |
| Low headroom type: Integrated design of the trolley and hoist, reducing lifting height loss. | ||
