How the Rotar RDP Series Delivers Peak Crushing Power On-Site
Power means nothing without reliability in demolition tasks. Every second on site, every movement of the attachment, and every tonne of concrete broken adds up to one question: how much power can it really deliver?
The Rotar RDP Series Demolition Pulveriser answers that question with proven performance and precision. Engineered for heavy-duty work, each model in the RDP line is built to maximise crushing power not just in theory, but in real-world demolition conditions. From reinforced concrete slabs to heavily armoured structures, the RDP delivers high-output performance with control, efficiency, and durability that operators can rely on.
RDP Rotar: Engineered for Heavy-Duty Work
Crushing power starts with intelligent engineering. The RDP Series combines high-grade materials, precision machining, and advanced hydraulics to convert every bit of input energy into breaking force at the jaws.
Replaceable Casting Teeth: The RDP’s cast teeth bite deep into concrete, breaking it faster and cleaner. When worn, they can be easily replaced on site, keeping the pulveriser operating at full strength without extended downtime.
Wear-Resistant Materials: Every contact surface is built for endurance. Heavy-duty wear plating protects critical zones from abrasion and fatigue, extending the lifespan of the attachment even in high-stress conditions.
High-Torque Upper Head & Slewing Ring: The RDP’s robust upper head and large-diameter slewing ring deliver smooth, stable rotation with high torque output. That means faster positioning and consistent control during every crushing cycle.
Integrated Speed Valve: The RDP’s hydraulics feature an automatic speed valve that intelligently switches between modes: rapid closing for cycle efficiency, and full power mode for maximum crushing force when the jaws meet resistance. It’s a built-in performance optimiser that balances speed with strength.
Together, these features make the RDP Series a true workhorse. It is powerful enough to handle primary demolition, precise enough for controlled breaking, and tough enough to keep working through the most demanding environments.
What Crushing Power Means On-Site
Crushing power is more than a spec sheet number. On the job, it determines how efficiently a pulveriser converts hydraulic energy into real work: the energy that fractures concrete, shears rebar, and clears debris.
For operators, crushing power translates directly into productivity and control:
Fewer passes to achieve full breakage
Cleaner material separation, ideal for recycling or secondary processing
Shorter cycle times to complete jobs faster
Better fuel efficiency through optimised hydraulic flow
This is where the RDP Series stands out. The combination of hydraulic precision and structural strength ensures every motion counts, reducing wasted effort and extending machine life.
How to Interpret Crushing Power When Choosing a Pulveriser
Selecting a pulveriser isn’t just about headline numbers. The true measure of performance comes from how effectively the attachment applies force where it matters: at the jaws, under real load.
When comparing attachments, look for:
Cycle Speed Under Load: How quickly the jaws open and close when actually crushing
Consistency of Force: Whether the tool maintains power through the entire stroke
Durability of Components: How long teeth, jaw plates, and hydraulic systems last before performance drops
The RDP Series scores high across all three. Its power-to-weight ratio and smart hydraulic system ensure reliable performance from the first crush to the final clean-up, making it a trusted choice for demolition contractors who value both muscle and finesse.
How the RDP Stacks Up
Compared to standard demolition pulverisers, the Rotar RDP Series offers a distinct edge:
Higher crushing force per kilogram, maximising the efficiency of your excavator
Faster cycle times, thanks to the integrated speed valve
Lower maintenance costs, through replaceable wear components and long-life materials
Proven reliability, in both primary and secondary demolition applications
The RDP’s precision-engineered build ensures it performs consistently across jobs of all scales, from high-rise concrete demolition to recycling operations and industrial dismantling.
