A mechanical attachment for bulk material handlers that grasps, lifts, and transports loose materials.
Technical details and manufacturing context for Bucket/Grab Mechanism
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Rated Capacity | 5–20 m³ | Material density determines actual payload |
| Closing Time | 8–15 s | Affects cycle time in continuous operation |
| Opening Time | 6–12 s | Faster opening improves discharge efficiency |
| Max Operating Temperature | 80 °C | Seals degrade above this temperature |
| Min Operating Temperature | -20 °C | Below this, steel becomes brittle |
| Ingress Protection | IP54–IP65 | Higher rating needed for dusty environmentsIEC 60529 |
| Material Grade | Q345B–Q460C | Higher grade for abrasive materialsGB/T 1591 |
| Weight | 2.5–8.0 t | Must match crane lifting capacity |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
| pressure: | Not applicable (mechanical system) |
| other spec: | Material density: Up to 3,000 kg/m³, Max particle size: 300 mm, Cycle rate: ≤15 cycles/min |

It is designed for loose or granular materials such as sand, gravel, coal, grain, and scrap metal. The actual suitability depends on the material's density, abrasiveness, and particle size, which should be matched to the mechanism's capacity and material grade.
The rated capacity is given as a range (5–20 m³) and is a reference. The actual payload depends on material density. You must calculate the expected weight per volume and ensure it does not exceed the crane's lifting capacity and the mechanism's structural limits.
The maximum operating temperature is 80°C, above which seals may degrade. The minimum is -20°C, below which steel becomes brittle. For extreme environments, consult the manufacturer for suitable materials and seals.
Ingress protection (IP54–IP65) indicates the level of sealing against dust and water. In dusty environments, a higher rating (e.g., IP65) is recommended to prevent particulate ingress that could damage hydraulic components. Verify the required rating based on your site conditions.
