Product Description

[Application scope and technical characteristics]
ZDY3500L(Q) is an integrated crawler mounted drill rig with high rotation torque and drill capacity. Multi degree of freedom mechanism is designed to achieve wide range of drill inclination/azimuth angle adjustment. The machine is capable to drill multi-layer holes and large angle holes. It can not only be used to drill in seam borehole along the roadway, but also suitable to drill boreholes across the belt conveyor (without remove the conveyor). Thanks for the advanced design concept and stable hydraulic system, ZDY3500L(Q) rig has an outstanding performance drilling gas drainage boreholes, water detection/drainage boreholes, pressure released boreholes and floor/roof large angle boreholes in roadways/tunnels.
