Product Tags

Nickel ore grabs are only suitable for picking up bulk materials. During the grabbing process of nickel ore, the nickel ore will be severely squeezed and the nickel ore will stick to the bucket and the grab will open. At that time, a large part of the material will stick to the bucket body. After the unloading is started, the grab must be closed before returning to grab the goods. The bottom plate of the new Nickel grab clamshell body is designed in a straight line and the interior of the bucket body does not have any ribs. In this way, when the grab grabs the nickel ore, the material will not be squeezed and the grabbed nickel ore will be loose, so the nickel ore will be completely unloaded when the grab is opened to discharge the material, and the grab will not need to be closed after discharge. Can continue to grab. In this way, the material will not fall down, hurt or fall to the ground or the sea during the entire crawling process, which will greatly reduce the pollution and loss.
