[Application scope and technical characteristics]
ZDY3500LP 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, ZDY3500LP 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.
[Techinical features]
1. Borehole can be drilled by ZDY3500LP without pulling down the belt.
2. Drill height adjustment, range from 1.45m~2.55m; Drill Inclination angle adjustment, range from-90°~+90°; Good manual, all hydraulic control, operating the valve's hand shank.
3. Easy to turn the direction of the rotary unit.
4. Load-sensitive control system to reduce energy consumption and achieve lower cost.
5. High quality hydraulic components(Rexroth and Sauer) maintain system reliability.
6. Stable hydraulic system is achieved by the application of cartridge valves.
7. Feed stroke can be customized, range from 1.25m-1.8m.
8. Drill rods can be deployed both form the back of rotary unit and in front of the rotary unit.
