Brokk introduces a new powerful machine!

Brokk, the world´s leading manufacturer of remote-controlled demolition robots, introduces the new Brokk 500 which features 40% more demolition power, the Brokk SmartPowerTM electrical system, a more powerful breaker, extended reach and industry-leading serviceability. And it adds a portion of good looks to the worksite as well.

Stronger – 40% more breaking power
The new Brokk 500 adds 40% more breaking power than its predecessor. The machine delivers 1,500 joules punch with each blow of the 700 kg heavy Atlas Copco SB702 hydraulic breaker. On top of that it adds further length to Brokk’s signature three-part arm system, now reaching 7,4 meters vertically and 7,0 meters horizontally, making it ideal for work where the extra reach is of importance. Still the Brokk 500 retains most of the compact proportions of its predecessor, the Brokk 400. With its 5,200 kg it is only marginally heavier and the width of the machine is the same. And it is “backwards compatible”, so all the tools and attachments used for the Brokk 400 can also be used on the new Brokk 500.

Smarter – Brokk SmartPowerTM
The Brokk 500 comes with Brokk’s new intelligent electrical system – Brokk SmartPowerTM. This new smart electrical system is a key part in creating the performance improvement of the machine. It maximizes the power output of the machine at any given time, based on both environmental and operating factors. The Brokk SmartPowerTM system is uniquely designed for the extremely tough operating environment of a demolition robot. Its components are either designed by or modified by Brokk to withstand the demolition forces over time. In addition it helps the operator to get the machine started on poor power supply, while at the same time it protects the Brokk machine from any harmful faulty power.

Tougher – Industry-leading serviceability
The Brokk 500 incorporates the industry-leading reliability and serviceability that Brokk has become known for over the years. New on this machine is that operators now can complete all daily and weekly maintenance without even having to lift the covers of the machine. And replacing any damaged hydraulic hoses is now simpler than ever.

The Brokk 500 will be available from May, 2017 – for more information visit www.brokk.com

Oslo’s Tåsen Tunnel achieves RWS-rated fireproofing with PassiveTec®

PassiveTec®’s innovative tunnel fire protection technology has been selected and installed for the renovation of Oslo’s Tåsen Tunnel.

To achieve a required 120 minutes fire protection (based on the RWS time/temperature curve), PassiveTec® fireboards have been applied as wall cladding in the tunnel.

PassiveTec® XT intumescent sealant was used for the expansion/construction joints, together with Fischer FNA II A4 anchors and tunnel coating from Kapyfract AG.

PassiveTec® Tunnel Liner fireboards are made from fibre reinforced magnesium and other refractory products. As well as outstanding fire protection performance, these specialist boards are free of hazardous substances, offer excellent stability and durability under humid, wet or freezing conditions and are easy and quick to assemble.

To further increase the speed of installation on the Tåsen Tunnel project, made-to-measure panels were cut to size and coated off site. The 24mm PassiveTec® Tunnel Liner used in Tåsen Tunnel is also the thinnest and lightest globally RWS-rated board.

Atle Killerud, Technical Manager at specialist fire protection contractor Firesafe, said: “When PassiveTec boards were submitted and tested for use in both tunnel lanes they were found to match – and in most cases exceed – the specification requirements. “The boards are currently being installed the project completion on both lanes expected during the early part of 2017. The project was handled in a professional and efficient manner, with materials being delivered on time.”

Delivered by main contractor Peab Norway for Statens Vegvesen, the 250 million NOK Tåsen Tunnel project is part of a comprehensive national tunnel upgrading  programme which will see more than 200 tunnels across Norway being upgraded by 2019. The upgrading works includes fire protection, new emergency exits and replacement of signalling and service equipment.

PassiveTec® director Simon MacDonald said: “We are naturally delighted that PassiveTec® TunnelLiner was selected for this important city-centre infrastructure project.

“This contract again demonstrates that with its ability to achieve superior fire and insulation protection in harsh environments, PassiveTec® TunnelLiner continues to set new standards for fire protection in tunnels.”

Full marks for Bergmann mining dumper 5025 … The sturdy mining dumpers 5025 from Bergmann known for their excellent manoeuvrability and power are a welcome sight on the tunnelling sites of Cannstatt and Feuerbach in Stuttgart. These compact two-axle machines with a payload of 25 t astonish even the most experienced machinery managers. Thanks to their low fuel consumption of only 14 litres per hour and a trough capacity of 15 m³, the heavy-duty dumpers compare favourably with machines from other manufacturers. Their most outstanding feature is the swivelling seat that offers excellent safety and optimised sight of the working area.

When the dumper is not loaded, the driver has a clear view of the travel path through the empty trough and can thus reverse the vehicle at a speed of more than 30 km/h, leaving other vehicles that need to turn to drive back well behind. Apart from the very short working cycles, it is the improved safety of the machine that has won over machinery managers when they decided on the equipment to be used in their tunnelling project … for more information, visit www.bergmann-dumper.de
