Versatility and manoeuvrability are said to be key features of Wirtgen’s new SP 33 concrete slipformer. This machine is available in both Offset and Crosspave versions, allowing it to be configured for a wide range of slipforming duties.
The machine is built on a modular design, boosting its versatility as users can set it up to handle a wide array of different slipforming applications. The machine can be used for paving monolithic concrete profiles such as kerbs and berms, rectangular profiles, concrete safety barriers up to a height of 1.3m, and drainage and gutter profiles.
When set up in the offset paving configuration, it can be used to pave concrete slabs with a pave width of up to 2.2m. But when operated in combination with a trimmer, it can even pave slabs up to 2.4m wide. The crosspave version meanwhile can pave slabs up to a width of 3m transversely in the direction of travel of the machine.
Both variants are controlled by the firm’s innovative operating system. The machine also features an ECO mode that monitors working load and parameters. This ensures automatic, load-optimised regulation of engine output for optimum efficiency and fuel economy, as well as minimising working noise. A further benefit of the machine is that it is equipped with Wirtgen’s AutoPilot 2.0. control system, which makes operation easier.
The machine has two crawler units with parallelogram swing legs at the front as well as a laterally adjustable crawler unit at the rear. According to Wirtgen, this allows zero-clearance installation and also ensures versatility. The crawler design is said to make the SP 33 highly suitable for use on construction sites that require a high degree of manoeuvrability as well as the ability to pave tight radii, as can be required in kerbing applications.
