Your Demolition Assistant—RSBM Double Cylinders Hydraulic Shear

The Role of Hydraulic Shears in Demolition

Hydraulic shears have become essential tools for demolition work. Mounted on excavators, these heavy-duty attachments use powerful hydraulic jaws to cut, crush, and tear apart structures. In fact, as industry experts note, shears “are one of the most powerful, versatile tools in the excavator attachment arsenal,” capable of slicing through steel beams, girders, and rebar easily. Beyond steel, shears can pulverize concrete and help separate metal from rubble, greatly speeding up demolition and recycling processes. They also eliminate the need for flame torches or jackhammers on site, which further reduces hazards. By combining crushing and cutting actions, a single shear attachment can replace multiple tools and steps, saving significant time on the job.

For example, the rotating jaws of many shears can reach into confined spaces for precise cuts, and they enable quick separation of steel rebar from concrete debris. Full 360° rotation of the shear (rotation around its vertical axis) further boosts efficiency by allowing operators to swing the tool freely without repositioning the excavator itself. In practice, this design lets contractors complete more cuts per hour with fewer machine moves, maximizing productivity on complex demolition projects.

Introducing RSBM Double-Cylinder Hydraulic Shears

RSBM’s double-cylinder demolition shears build on this legacy by offering advanced, highly customizable designs. Each RSBM model emphasizes multifunctional customization: one attachment can be fitted to perform a range of tasks on site. For example, a single RSBM shear can be configured to crush reinforced concrete, cut steel beams, or even dismantle scrapped vehicles — all without needing to swap tools. This flexibility means crews carry fewer attachments and spend less time switching equipment, which saves both labor and equipment costs in the long run. In fact, RSBM’s durable construction and wear-resistant materials translate into a lower total cost of ownership over the life of the machine.

In addition, RSBM’s double-cylinder layout (two hydraulic rams side by side) provides extra power and stability. This dual-cylinder design balances the closing force across the jaws and allows extremely high cutting pressure. As a result, the shear can bite through very thick concrete or steel much more smoothly than a single-cylinder tool. The large, heavy-duty cylinders and robust seals are built for continuous use, so RSBM shears deliver consistent performance even under the harshest conditions. Over time, these engineering choices give contractors a reliable tool that works day after day without failure.

Main Features of RSBM Hydraulic Shears

• Wear-Resistant Steel: RSBM shears use premium abrasion-resistant steel in their jaws and frame. It is specifically engineered to resist wear and abrasion (nominal hardness ~400 HBW) while remaining tough. In practice, this means RSBM shears maintain sharp cutting edges and structural integrity through heavy-duty use, greatly extending the attachment’s service life.

• High-Force Dual Hydraulic Cylinders: Each RSBM shear is powered by reinforced double cylinders that generate enormous jaw-closing force. The design ensures hydraulic pressure is applied evenly, maximizing cutting power. The cylinders and seals are over-engineered to handle high pressure and heavy loads without leaking or failing. In short, this dual-cylinder setup gives the shear outstanding bite and reliability.

• 360° Continuous Rotation: The shear’s mounting includes a full-rotation swivel, allowing its jaws to rotate endlessly around the vertical axis. This continuous 360-degree rotation gives operators complete freedom to position the shear at any angle without moving the carrier excavator. Industry tests note that a full-rotating shear delivers higher efficiency because the operator can cut continuously in all directions.

• Speed Valve for Fast Cycles: An internal speed (flow-regeneration) valve accelerates the hydraulic circuit to reduce cycle time. When activated, it redirects oil flow to speed up the jaws’ opening and closing motion. This feature dramatically shortens each cutting cycle: third-party data show that a speed valve can improve shear cycle time by up to 50% compared to a standard system. The net effect is faster cutting operations and higher throughput on site.

• Wide Jaw Opening & High-Strength Frame: RSBM shears open extremely wide for handling large debris. The jaw hinge and frame are built from high-tensile alloy steel, and gussets reinforce the structure. A wider opening allows operators to insert large pipes, beams or concrete slabs into the jaws easily. The high-strength jaw plates resist bending even under heavy load, so large workpieces can be gripped and cut in one go.

Advantages in Real-World Demolition

• Efficient Steel–Concrete Separation: RSBM shears excel at cutting mixed-material structures. An operator can clamp a reinforced concrete element and the shear will simultaneously crush the concrete and slice through embedded steel rebar. This combined action rapidly separates steel from concrete on site, simplifying debris sorting and speeding recycling. In effect, one pass of the shear replaces separate concrete-breaking and torch-cutting steps, saving significant time and labor.

• Primary and Secondary Demolition: RSBM shears handle both major tear-downs and fine-detail work. Documentation explicitly notes that these shears are “suitable for both primary and secondary demolition tasks”. In primary demolition, the shear can break down large structures (walls, columns, etc.), while in secondary demolition it can make precise cuts to remove remaining pieces or sort rubble. Using one tool for both phases gives crews maximum flexibility and reduces equipment changeovers.

• Dual-Action Blades (Crush and Cut): The jaws on RSBM shears are equipped with heavily reinforced upper and lower blades. In operation, the upper jaw’s pointed blades pulverize concrete while the sharp lower blade simultaneously cuts any steel or rebar. This dual-action design means the shear effectively acts as a crusher and cutter at the same time. As a result, one swing of the shear can both crush concrete and shear steel in a single stroke, greatly improving demolition speed.

• Convenient Large Opening: The extra-wide jaw opening means operators can grab big debris easily. Instead of needing multiple smaller bites, crews can catch entire sections—such as broad wall panels or bundled scrap—in one go. This convenient design speeds up loading material into the shear and reduces the number of cycles required per item. On the job, that translates to faster work and a smoother workflow.

• Protected Hydraulic Cylinder: RSBM shears feature a fully encased hydraulic cylinder. The heavy protective cover shields the cylinder rod from flying concrete and metal shards. This prevents dents or scratches on the piston, extending cylinder life and preventing hydraulic leaks. In practical terms, it means the shear continues to operate reliably day after day without downtime for maintenance.

• Fully Mechanized, Safer Operation: Using an RSBM shear keeps operators safely inside the cab while all cutting is done hydraulically. No manual cutting or torch work is needed. According to field reports, this mechanized approach can make demolition two to three times faster than using a breaker alone. At the same time, it greatly improves safety: there are no sparks or flying shards as with torch cutting, and minimal vibration is transmitted to the machine. The shear does the hard work while the operator stays protected, letting crews work longer with less fatigue.

• Low Noise and Vibration: RSBM hydraulic shears run much quieter and smoother than impact tools. They are specifically noted for “low noise, no vibration,” meeting strict environmental requirements for urban demolition projects. This quiet operation allows crews to work longer with less fatigue and causes less disturbance to nearby occupants. Reduced vibration also means less wear on the excavator and lower maintenance costs for equipment.
