Mechanized scaling replaces manual high-risk work. Smart control. Compact design. Built for mines that prioritize safety and efficiency.

Scaling is one of the most dangerous jobs in underground mining. Removing loose rock from tunnel walls and roofs after blasting puts workers directly under unstable ground. Falls of ground remain a leading cause of fatalities in mining.

The industry is moving away from manual scaling. Mechanized equipment is taking over. Beijun Group offers a range of scaling jumbos designed to replace dangerous manual work with machine power and precision.

Scaling – A Critical Step in Mine Safety

After blasting, tunnel walls and roofs have loose rock. That rock must be removed before workers can enter. The process is called scaling.

Manual scaling uses metal bars. Workers stand under the face they are clearing. Loose rock can fall at any moment. The work is slow, physically demanding, and dangerous.

Purpose-built scaling jumbos solve these problems. Operators work from a protected cab or remotely. The machine does the heavy work. Workers stay out of the danger zone.

Industry reports confirm the trend. A 2025 report notes that "scaling machines replacing manual scaling, carrier-mounted charging replacing manual carrying, and hydraulic drills replacing manual drilling" have contributed to massive productivity gains.

Real-World Applications – Intelligent Scaling in Action

In June 2026, China Huaye Mining held a technology showcase at its Xulou project in Anhui Province. The event highlighted two key innovations: a vehicle collision avoidance system and an intelligent scaling jumbo.

The intelligent scaling jumbo integrates hydraulic power, smart controls, and vision modeling algorithms. It replaces manual high-risk scaling with mechanized, intelligent operation. The machine significantly improves scaling efficiency and reduces safety risks.

The technology is already in full operation at the Xulou project, providing solid technical support for safe and efficient mine production.

Another example: in early 2026, a mine in China invested 1.6 million yuan in a hydraulic drilling jumbo and planned to add a scaling jumbo to its fleet. The mine organized specialized training for workers to operate the new equipment.

Beijun Scaling Jumbo – Built for Real Mines

Beijun Group manufactures scaling jumbos as part of its full underground equipment lineup[citation:1]. The machines are designed for the specific conditions of underground mining.

Remote operation. Operators control the scaling jumbo from a safe distance. This is the biggest safety improvement. Workers are no longer standing under unstable rock.

Purpose-built design. Beijun scaling jumbos are designed specifically for scaling work. Unlike repurposed excavators or drill rigs, dedicated scalers deliver faster cycle times and better results.

Compact dimensions. Underground tunnels are tight. Beijun scaling jumbos are designed to navigate narrow drifts and tight corners. The machines fit where larger equipment cannot go.

Strong hydraulic system. The scaling arm delivers the force needed to break loose rock efficiently. The system is designed for continuous operation in harsh underground conditions.

Durable construction. Beijun uses high-strength steel and rigorous welding standards. The machines hold up to the constant shock and vibration of underground work.

Compliance and certification. Beijun scaling equipment carries ISO9001, EU CE, and KA mine safety certifications. The equipment meets international standards for underground mining.

Beijun – A Full-Line Underground Equipment Manufacturer

Beijun Group is a high-tech enterprise integrating R&D, manufacturing, sales, and service. The company is based in Jining, Shandong Province, with over 500 employees including 50+ engineers.

The company's product range includes underground dump trucks (3.5 to 45 tons), underground utility vehicles, wet shotcrete machines, rock drilling jumbos, scaling jumbos, anchor bolters, and aerial work platforms.

The company's manufacturing facilities include automated welding lines, robotic welding, laser cutters, CNC milling machines, and coordinate measuring machines. Beijun is equipped for full-process quality control.

Beijun's equipment is exported to more than 20 countries with overseas branches in Chile, Peru, Kazakhstan, and other locations.

What This Means for Buyers

If you are considering a scaling jumbo for your mine, here is what matters.

Look for remote operation. Safety is the primary reason for mechanized scaling. Remote control removes the operator from the danger zone. This is the most important feature.

Check compact design. Underground mines have tight spaces. Scaling jumbos need to fit through narrow drifts. Beijun machines are designed for these conditions.

Consider build quality. Scaling is hard on equipment. High-strength steel and robust hydraulics matter. Beijun uses proven components and construction methods.

Think about service support. Parts availability and technical support are critical. Beijun has a global service network and regional parts warehouses.

Look at the full lineup. Mines benefit from standardized equipment. Beijun offers a full range of underground machines. That means common parts and maintenance procedures.
