Operator Safety and Comfort:
The demonstrations focussed on three pieces of equipment – the Conjet hydrodemolition robots Jetframe 101 Nalta and Robot 327 and the Calder MulitJet which provided the high pressure water. Both hydrodem machines are a huge step forward in safety through semi-automation – keeping the operator in control, but at a distance from the area of operation. Whilst these machines offer major increases in production rates, talk on the day was predominantly about the advances in operator safety and comfort.
Nalta – the world’s smallest hydrodem robot. The Nalta is a frame-mounted, concrete cutting head. Set against the workpiece, the head traverses the face to be cut, and indexes to the next cutting position automatically allowing sizable areas to be worked on between positioning activities.
The Nalta is mounted on a frame constructed of standard scaffolding tubes and can be used in areas which are confined or awkward to access.
High Pressure Water:
Providing the high pressure water was this mobile jetting unit featuring the ever-reliable Hammelmann pump and the latest in ultra-low emissions, Tier 4, engine technology. Part of the MultiJet range of onshore and offshore jetting units, this machine benefits from over 30 years’ of design and development.
During the current major roadworks on the M5 Oldbury Viaduct you will see numerous Calder-built jetting units being used by various operators for bridge joint preparation.
Service and Spares:
Full after-sales support is provided from Worcester, UK. A team of technicians can help through ad hoc maintenance visits, service contracts, emergency call-out, and telephone support.
