MPPK RIPPER-LOADER
A bucket-type ripper-loader is a version of the Type MPP Ripper and is developed based on the common power and travelling module. This machine enables to raise labour efficiency 3.0 to 3.5-fold, eliminate manual loading of the rock and ripping of the bed. It is noteworthy that the machine is small in size, rather manoeuvrable, easy in operation and reliable in servicing. Due to the specially-designed collapsable boom applied, the digging area may be extended and bucket filling increased. The machine may be also used for carrying out another operations. Slinging elements are provided in the machine to lift and transfer separate loads and to perform rigging operations.
