How to choose the right grab
- Clarify your purpose：
Before delving into the options, please clarify your specific requirements.Ask yourself：
- What materials do you want to deal with?(Logs, scrap metal, stone, etc.)
- What tasks will the grab perform?(Loading, sorting, dismantling, etc.)
- What type of device will it be connected to?(Gantry crane, overhead crane)
- What is the specific gravity of the material you grab?The number of cubes of the grab?
What is the tonnage of your crane equipped with a grab?
According to the characteristics of the material being grabbed, the grab is usually divided into four basic types: light, medium, heavy and super heavy.
| The type of material to grab | Grab material | Capacity weight(t/m³) |
| Light | Coke, slag, grains, potatoes, medium-quality anthracite lime, cement, soil, gravel, clay, broken bricks, etc. | 0.5~1.2 |
| Medium | Peat, large pieces of anthracite coal, compacted coal, clay, limestone, gravel, salt, gravel, bricks, bauxite, flakes of iron oxide, cement, sand and bricks in water, etc. | 1.2~2.0 |
| Heavy | Limestone, heavy clay, small and medium-sized ores, hard rock, rod-shaped iron oxide, iron ore, lead concentrate powder, etc. | 2.0~2.6 |
| Overweight | Large ores, large manganese ore, sedimentary agglomerated lead ore powder, etc. | 2.6~3.3 |
- Accessory compatibility: Ensure that the grab is compatible with existing equipment.
- Budget considerations: The price range of the grab is different.Balance your budget based on the function and durability of the grab.
- Comments and suggestions: Research online, read user reviews, and seek suggestions from industry peers.
- Go to the crane manufacturer for on-site inspection and testing before purchasing: test the grab under real conditions as much as possible.Evaluate its performance, ease of use, and overall functionality.
