Loading And Unloading Hydraulic Rotary Grab Bucket

The loading and unloading hydraulic rotary grab bucket are usually used with cranes used in ports, steel mills, ships and power plants.. Including tower cranes, ship cranes, traveling cranes. It primarily serves the purpose of handling powder and fine bulk materials like chemicals, fertilizer, grain, coal, coke, iron ore, sand, particle construction materials, mashed rock, and so on.

The grab buckets can be divided into various types according to various standards. Additionally, the following are the general classifications of crane grab buckets.

Crane grab buckets can be divided into clamshell type, orange peel type, and cactus grab type categories based on their shapes. For silty, clayey, and sandy materials, the most common grab bucket is the clamshell. When removing large, irregular pieces of rock and other irregular materials, the orange peel grab bucket is frequently used. The orange peel grab usually doesn’t close very well because it has eight jaws. The cactus grab bucket can simultaneously handle both coarse and fine materials. With three or four jaws that work well when closed to form a proper bucket.

Crane grab buckets can be categorized as light type, medium type, heavy type, or extra heavy type depending on the bulk density of the materials. Materials with a bulk density of less than 1.2 t / m3 can be handled with a light crane grab bucket, such as dry grain, little bricks, lime, fly ash, aluminum oxide, sodium carbonate, dry slag, and so on. The medium crane grab bucket is used to handle things like gypsum, gravel, pebbles, cement, large blocks, and other materials with bulk densities between 1.2 -2.0 t/m³. The heavy crane grab bucket is used to move things like hard rock, small and medium-sized ore, scrap steel, and other materials with a bulk density of 2.0t – 2.6 t / m³. The extra heavy crane grab bucket is used to move things like heavy ore and scrap steel that have a bulk density of more than 2.6 t / m3.
