The HY-50H drilling rig produced by Guangzhou Huanyu Drilling Machinery Co., Ltd. is upgraded on the basis of the 50 series of drilling rigs, which solves the operation mode of traditional small hydraulic drilling rigs that have short drill rods and need to repeatedly lift and drill down during drilling. This model has a new crawler chassis, which reduces the user’s transition burden and improves work efficiency. The drill pipe core drill is placed on the chassis, and the engine can be transitioned. At the same time, the machine transfer function is added. Under the manufacturing of our factory, the length of the drill rod is 3 meters and the height of the drill tower is 4.5 meters. The operation process is simplified. The rod change does not require the removal of the bull head gyrator, which increases the drilling speed.
