Fixed or rotational drum cutters? Epiroc drum cutters can do bothPublished 29/6, 2020 at 16:55
‘Pro bracket’ is a high quality, rigid manifold for transverse drum cutters, delivering consistent output quality and efficiency with increased investment protection being the key features of the new product.
Epiroc’s drum cutters have endless 360o hydraulic rotation, enabling optimal positioning and the precise handling of the drum cutter. The new Pro bracket fixed manifold significantly improves the protection of the hoses when working in confined areas and where there is limited visibility, without compromising the exemplary quality and performance. While the tried and tested hydraulic rotation unit continues to prove popular with its precision and flexibility, the Pro bracket primarily offers additional protection of the customers' investment in the machine for particular applications.
Optimised hose guidance is achieved as the hydraulic hoses run directly along the excavator arm and are fed out to the back in the centre of the extension arm for protection. This means that they are subjected to significantly less mechanical strain, do not cross each other and are better protected during work with minimal visibility of the cutting heads (e.g. during channel construction, close to walls, in tunnels or in water). A robust design in the form of a closed box prevents any demolished material from falling onto the engine cover from above.
The rigid bracket, with its range of usage options, is particularly flexible, being suitable for even the most challenging applications and can also offer a number of useful options. Epiroc offers the Pro bracket with an optional water spraying system to meet the ever increasing requirements for dust suppression during demolition work, tunnel and channel construction. The installation of an optional additional valve enables the overflow oil line and return to be combined so that the drum cutter can be connected to the breaker circuit of the excavator with just two hoses. The option is available to choose either a rotating or static support bracket depending on customer requirements.
