Boomer 281/282 Boring Rig
The full hydraulic excavation drilling rig is mainly used for tunnel excavation and underground drilling and blasting construction projects. This series of drilling rigs adopts rubber tire travel mode and diesel engine as the power system of the whole vehicle. According to different construction conditions, different types of drilling arms, propelling arms and different lengths of rock drilling rods are selected for the heading drilling vehicle. At present, the most widely used full hydraulic excavation drilling rigs in the domestic and foreign markets are the Boomer series drilling rigs produced by Atlas Copco.
