Features

The operators under the mine have been asking to reduce the machine’s weight. This series is to meet for their needs. This type is 5kg lighter than the same style. With foreign new type engineering plastic parts instead of the aluminum parts on the unstressed parts(water jacket,valve block and manipulate handle),the work strength, toughness and wear resistance greatly enhanced, and weight is greatly reduced.
