Mass Production of FKQM45 Scaling Machine Launched

As a special trackless working equipment independently developed for underground mining scenarios, the FKQM45 underground scaling machine is mainly used to clean loose and dangerous rocks on the roof and side walls of excavation roadways and stoping faces. It completely replaces the traditional manual scaling mode, fundamentally eliminating major safety hazards such as falling rock injuries and collapse burying for workers operating at height underground. Meanwhile, it greatly improves the overall construction efficiency of roadway surrounding rock cleaning and cuts long-term labor costs for mines. Conventional simple scaling equipment available on the market generally has many drawbacks: oversized bodies that cannot enter narrow roadways of small and medium-sized mines, limited movement angles of mechanical arms, unstable hydraulic system pressure with insufficient impact force, and low overall protection levels. These defects make them difficult to adapt to complex and harsh underground conditions including high humidity, heavy dust, scattered gravel and inclined roads. During the early research and development phase, the FKQM45 team fully investigated the pain points of mine users in various regions around the world, carried out targeted structural optimization and hydraulic system upgrades aiming at all kinds of equipment defects, and redesigned four core modules: overall vehicle layout, walking transmission mechanism, crushing arm assembly and power heat dissipation unit, comprehensively improving the equipment’s adaptability, durability and operation safety. The whole machine adopts an integrated welded low and narrow body design. The overall contour dimensions have passed multiple rounds of simulation verification, allowing smooth passage through narrow underground roadways within three meters. No pre-widening of roadways is required before operation, which greatly reduces capital investment for roadway transformation in mines. The body plates are made of thickened special wear-resistant steel with full welding reinforcement at joints. All exposed pipelines of the whole machine are uniformly equipped with anti-collision wear-resistant protective sleeves. Reinforced dust and splash baffles are installed in key areas of the body, together with complete explosion-proof warning signs, fully complying with safety specifications for underground mine operations. The walking system adopts a four-wheel independent hydraulic drive structure matched with heavy-duty solid wear-resistant tires with deepened patterns. The tire ground gripping performance has passed thousands of underground road simulation tests. It can maintain stable driving on various complex road surfaces such as muddy water accumulation, gravel accumulation, longitudinal inclination and transverse slope, without wheel slipping, body skidding or tire burying failures. The drive hydraulic motor is precisely matched with variable hydraulic pumps, with adjustable walking speeds at multiple gears. The low-speed mode is suitable for precise scaling operations, while the high-speed mode supports rapid equipment transfer, balancing operation accuracy and transit efficiency. The core working unit of the equipment is a multi-section telescopic composite crushing mechanical arm, integrating multiple degrees of freedom including multi-stage expansion, horizontal rotation and vertical pitching. There are almost no dead zones in the operation coverage, enabling easy access to high-risk areas hard to reach by workers, such as roadway roof corners, deep parts of roadway sides and support gaps. The quick-change interface at the front end of the mechanical arm allows fast disassembly and assembly of crushing picks of different specifications. Relying on large-flow high-pressure plunger hydraulic pumps to continuously output stable impact kinetic energy, each impact is uniform and lasting, which can break loose surrounding rock layer by layer and avoid sudden underground safety accidents caused by instant falling of large dangerous rocks, effectively reducing the daily safety management pressure of mines. The whole machine is equipped with a complete independent hydraulic power assembly, including full sets of hydraulic components such as variable plunger pumps, large-flow multi-way directional valves, high-pressure accumulators, silent oil cylinders and wear-resistant sealing kits. The entire hydraulic system has passed tens of thousands of high and low pressure cycle durability bench tests. Under long-term continuous operation, the volumetric internal leakage is controlled at an extremely low standard, without common failures such as power attenuation, reduced impact force and sharp oil temperature rise. A matched independent large-capacity heat dissipation device ensures sufficient circulating cooling efficiency of hydraulic oil. Even in underground environments with poor ventilation and high ambient temperature, it can maintain constant temperature and stable operation of the hydraulic system, extend the service life of all core hydraulic accessories, and reduce mine production losses caused by frequent equipment maintenance and shutdown. The cab adopts a closed explosion-proof protective structure, equipped with shock-absorbing seats, anti-slip operation pedals and multi-angle adjustable control handles. The operation view is wide and unobstructed, and operators are completely separated from the crushing impact area, lowering safety risks through operation layout design. A high-definition explosion-proof monitoring display can be optionally installed in the cab to synchronously display the front-end operation picture of the mechanical arm in real time, enabling precise remote control of crushing points without close observation of the working face, further avoiding the risk of injury from falling rocks. To meet differentiated usage demands of mine customers all over the world, the FKQM45 supports all-round optional customized transformation services. The overall vehicle width and maximum extension stroke of the mechanical arm can be adjusted according to the actual width of roadways; a wet spray dust removal device can be installed to suppress dust diffusion synchronously during crushing operations, optimize underground air quality and reduce the probability of pneumoconiosis among operators; an intelligent electronic control module can be upgraded with functions such as operation duration statistics, automatic pressure early warning and fault code self-inspection; the chassis protective steel plates and tire sidewalls can be thickened to adapt to high-intensity mining scenarios with abundant gravel and frequent collisions in mines. All hydraulic accessories, sealing parts and transmission components of the equipment adopt general standardized specifications, which can be conveniently purchased and replaced at mine maintenance outlets around the world without special customized parts, greatly shortening the later operation and maintenance procurement cycle and comprehensive maintenance costs. With the continuous tightening of mine safety production control standards in countries worldwide, the manual scaling operation mode with workers entering high-risk areas is gradually eliminated, and the market demand for automatic professional scaling equipment keeps rising steadily. With four core competitive advantages including compact passage size, powerful and stable crushing impact performance, long-lasting durable hydraulic system and full-dimensional safety protection system, the FKQM45 has received a large number of purchasing intentions from mining enterprises at home and abroad. After being launched into the market, the equipment has obtained positive feedback from numerous frontline operators and mine operation and maintenance managers. The actual underground operation efficiency is several times higher than traditional manual scaling, and the equipment failure rate is far lower than similar general crushing equipment. The R&D team continues to iterate and optimize the overall performance of the FKQM45 aiming at extreme mine working conditions in different regions of the world. In the follow-up phase, the intelligent auxiliary control system will be further upgraded with functions of automatic obstacle avoidance, cloud storage of operation data and remote fault diagnosis to realize full-process digital management of scaling operations. Meanwhile, the matching logic of the hydraulic system will be continuously optimized to reduce the overall fuel consumption of the equipment, cut energy expenditure for mine mining, and help all kinds of mining enterprises realize green, safe, efficient and low-cost underground surrounding rock cleaning operations.
