The entire rig adopts a modular design, consisting of three parts: the power vehicle, the main unit, and the crawler transporter. It features a compact structure, allowing well-to-well transfer without complex and tedious disassembly, with convenient transfer and transportation. It offers excellent adaptability for operations in complex conditions such as low-height and narrow spaces. Equipped with an innovative closed heavy-duty drive system, its rock-breaking capability covers various complex geological strata.
