28T 15CBM Hydraulic Grab Bucket is a clamshell grab bucket with a maximum lifting capacity of 28 tons under the crane hook, a maximum grab volume of 15 cubic meters based on a material specific gravity of 0.8-2.6t/ m3, a maximum grab weight of 18 tons, and a grab dead weight of about 9.5 tons. The Electro Hydraulic Clamshell Grab Bucket has an electro-hydraulic drive to grab powdery or granular bulk materials, and its structure is made of high-strength wear-resistant materials.
How to pick the right electro hydraulic grab bucket?
1. Electro hydraulic grabs are mainly used for grabbing bulk goods, such as coal, ore, yellow sand, etc.;
2. High requirements on the strength of the grab;
3. The lifting capacity and other parameters of the electro hydraulic grab bucket should be matched with the crane;
4. The grab's hydraulic system pressure should be matched with the use of the scene or crane, to avoid the pressure being too high or too low;
5. According to the material to be grabbed, choose the suitable capacity of the grab to avoid low efficiency or overloading;
6. According to different material requirements to choose an Electro Hydraulic Clamshell Grab bucket or an Electro Hydraulic Orange Peel Grab bucket, such ore, steel chips, and other large hard materials need to be Electro-hydraulic Orange Peel Grab buckets, sand, grain, coal, and other powdery or granular materials need to be Electro-hydraulic Clamshell Grab buckets;
7. According to the ultra-high temperature, ultra-low temperature operating environment choose high temperature resistant, low-temperature resistant materials made of non-standard electro-hydraulic grabs.
