SERMAC SIRIO 5RZ46 SUPERLIGHT TRUCK MOUNTED CONCRETE PUMP

The 5RZ46 Superlight has been specifically designed to meet market demands for maximum versatility. The multi-fold ‘RZ’ boom design combines both roll-fold and z-fold opening for extreme manoeuvrability and allows the boom to open into its full reach of 45.1m at the exceptionally low height of 9.10m. The short wheelbase of 4.8m also makes it remarkably agile to drive considering the size of the boom. This makes it the ideal pump for placing concrete in the most awkward and confined spaces. The sophisticated lightweight structure of the 5RZ46 has been achieved through the use of S900 special steel, which allows the 46m reach, 5 section multi-fold boom to be mounted onto an 8x4 cab chassis and still weigh under 32 tons, keeping it within the UK weight limit.

The 5RZ46 Superlight has a maximum output of 150 cubic metres per hour and can discharge concrete at a horizontal reach of 41.1m and a downward reach of –33.1m. The hydraulic stabiliser legs have also been designed so that the pump can set up in minimal ground space (rear 8.0m, front 8.3m). This, combined with the flexibility of the boom, means that the pump is able to work on a wide variety of projects from tunnelling and small DIY building jobs right up to concrete placement at 14 storeys high. 

This pump is available in three different levels of concrete outputs from 130m3/h to 185m3/h at pressures of up to 76 bar.

FAQs

Q. WHAT BOOM SIZES ARE AVAILABLE?

Concrete Pumps are available with boom lengths ranging from 20 metres to 65 metres. This wide range allows customers to select the most suitable machine for their project requirements, whether they need a more compact pump for sites with tighter access or a larger boom for high-reach and long-distance placing applications. Having multiple boom sizes makes these pumps suitable for everything from general construction work to larger, more demanding concrete-placing projects.

Q. WHAT ARE THE TRUCK OPTIONS?

These pumps can be fitted to any UK or European truck chassis, giving customers a high level of flexibility when specifying their machine. This means the pump can be matched to preferred truck manufacturers, site requirements, and operator preferences.

Q. DO THEY HAVE A STABILITY SYSTEM?

Yes, every pump is fitted with a stability system as standard, using Sermac’s SCS control system, which is designed to help ensure safe, stable operation during pumping. Stability is a key consideration for truck-mounted concrete pumps, particularly with larger booms, and the inclusion of Sermac’s control system helps support safety and performance.

Q. WHAT IS THE LEAD-TIME?

The typical lead time is 12 to 16 weeks from receipt of chassis. This gives time for the pump to be fitted, prepared, and completed to the required specification.

Q. ARE THEY FITTED WITH TWIN WALL PIPES?

Yes, twin-wall pipes are fitted as standard. This provides increased durability and wear resistance, which is especially important when components are exposed to constant abrasion from concrete flow. Having twin-wall pipes as standard helps improve service life, reduce wear-related downtime, and support reliable long-term performance on site.
