Shaanxi Xianfeng Rock Drilling Machinery Co., Ltd.has successfully repaired a Montabert HC109 hydraulic rock drill for a domestic mining client, enabling this critical tunnel excavation equipment to resume operation within a tight timeframe.

HC109 is the main equipment for underground tunnel excavation and ore drilling operations, and requires comprehensive maintenance, including component replacement and hydraulic system calibration. Pioneer's technical team used precision tools and factory compatible components to solve the wear problem of core components such as gears and seals, ensuring that the rock drill meets Montabert's performance standards.

Shutdown is costly for mining operations, "said a representative of Pioneer." We focus on fast and reliable repairs to minimize the impact on our customers

The repaired rock drill has been put into use in underground tunnel engineering and can maintain the iconic 3750 impact frequency and 13 kW impact power of HC109- which is crucial for drilling 45-76 mm holes in hard rock. Pioneer Company focuses on the maintenance of Montabell tunneling machines and has a good track record of providing support to mining and tunnel engineering customers across China.
