1. Characteristic of XYC-200A tricycle-mounted drilling rig XYC-200A tricycle drilling rigs is multi-function hydraulic vehicle-mounted rotary drilling machine . The tricycle is Tricar 7YP-1475D1. The drilling rig, engine, BW-160 pump and hydraulic drill tower are all installed on the tricycle, so it us easy for transportation. XYC-200A drilling rigs with BW160 pump which has high pressure and high flux, to ensure the drilling depth and hole diameter. The tricycle drilling rig is equipped with shift unit,so the drilling rig can move back and forth The highest speed can reach 1045r/min with 5 gears, which improves the drilling efficiency The rig is Adopted 53x59 drilling rod, which has high rigidity and strong delivery torque Equipped with national patent technology---taper clutch, made the machine easy to operate and free of maintenance. Use large module planetary gear and add supporting frame, highly increased hoisting and braking ability of the winch. Vertical spindle are fixed by four groups of bearings to ensure that the rotary machine is rigid enough for gravel layer and other complex geological conditions.
