Grab type editing

The basic conditions for ensuring that the grab grabs the material are: There is a suitable bucket type, basic size and sufficient weight. According to the characteristics of the grabbed material, the grab is often divided into four basic types: light, medium, heavy, and extra heavy. The weight ratios of the various types of grabs to fit materials and weights to materials are shown in Table 1. The weight of the medium-sized grab is approximately equal to the weight of the material, the weight of the light weight is smaller, and the weight of the heavy weight is greater.

For various types of grapples, the corresponding parameters and structure types should be selected. Double grapple grabs are suitable for grabbing granules and powders. When grabbing material with a grain size greater than 100 mm or a solid material, rakes should be made with tape. When the unloading of the quasi-track vehicle using the grab, the grab volume is generally not more than 3m. Multi-claw (also known as lotus) grabs, the number of brooms is generally six, and the cuts in the jaws are sharp, suitable for grabbing materials that are difficult to insert into the double jaws grabs, such as large hard ore, aluminum Ingots, iron filings, scrap, etc.
