The crushing and screening sector has seen a flurry of new model launches in recent months, with a series of new equipment introductions - Mike Woof writes. Crushing and screening systems play a vital role in the overall cost effectiveness of a quarrying operation. Ensuring that a quarry runs efficiently relies heavily on the appropriateness of the entire crushing and screening set-up for the material input, the output grades and the compatibility of each separate unit. Mobility has been a key issue in rece

A modern, six-lane suspension bridge is under construction across the Sea of Marmara near the western Turkish town of Izmit. Turkish crane service provider Aydin Vinc is putting a 180tonne Sennebogen 5500 crawler crane to good use on lifting and logistics tasks. When finished in 2017, the six-lane Izmit Bay Bridge, 50km east of Istanbul, will carry more than 5,000 vehicles per day.

Swiss civil engineering company Scrasa has made a successful investment in a Hitachi ZX470LCH-5 as the main production machine for its sand and gravel pit. The large Zaxis-5 excavator was delivered to Scrasa’s Satigny site on the outskirts of Geneva by the country’s Hitachi dealer, Probst Maveg. The ZX470LCH-5 is part of a fleet of machinery that includes two ZX225USLC-5s, a ZX135US-5 and a ZX85USBLC-5, but it is the only machine based at Satigny. Scrasa said the ZX470LCH-5 plays a key role in the excava

Two major developments being introduced will help optimise traffic flow on routes carrying high volumes of vehicles/day. An installation of Flexicon’s flexible conduit will help keep the traffic flowing on one of the busiest sections of the M6 motorway through Birmingham by protecting power and data cabling for overhead gantries and CCTV cameras. On behalf of Highways England, who is implementing a hard shoulder running scheme between junctions 5 and 8, contractor’s Carillion is using the 63mm diameter L

Recycling of road surfaces has resulted in restoration and full renovation of a key California route. State Highway 137 in California’s San Joaquin Valley had suffered badly from the effects of weather, traffic and general ageing and the California Department of Transportation recognised the need to improve this route. A 15km section of State Highway 137 west of Tulare, which lies about midway between Fresno and Bakersfield, in the heart of the Central Valley. The road runs through the vineyards and almo

Gülay Malkoc discusses the importance of investing in road maintenance.

Saint-Gobain PAM UK is now offering the Opt-Emax and Ult-Emax variants of its anti-skid treated GripTop range of access covers. These units have been developed to help boost safety for vulnerable road users such as motorcyclists and cyclists in particular. Conventional access covers can wear away over time and become smooth and slippery due to decades of traffic. These pose major hazards to motorcyclists and cyclists, particularly in poor weather. The GripTop range from Saint-Gobain PAM UK features D400 an

Improved pedestrian safety is being achieved in Qatar with the help of new technology. AGD Systems and Qatar-based Traffic Tech Group have joined forces to install pedestrian detection systems. Traffic Tech Group will be AGD’s exclusive global distributor for the Puffin and Toucan pedestrian crossings in the region to increase pedestrian and cyclist safety and improve traffic flows. On-street trials of AGD-enabled Puffin and Toucan schemes commenced in late 2014 at a dual pedestrian crossing on the busy A

Fast repair of Cairo’s busy urban highway has been achieved using paving equipment. And MOBA levelling technology played an important role in ensuring finish quality met requirements. Cairo is Egypt’s fast-growing capital city, with an estimated population of around 20 million living in its catchment area. The city’s fast growth rate however has placed enormous demands on its infrastructure, with transportation creaking under the strain. An increasing numbers of people use the roads in and around Cairo ev
