Kleeman, from the house of Wirtgen, exhibited its new range of MC 110, 28x44 mm tracked jaw crusher. Its prime feature is its portability and ease of transportation. Fitted with tier-4 engines, it has a diesel electric drive. Kleeman also introduced its MR 130, 36x50 mm impact crusher with constant feed system. It also demonstrated its new intelligent control system ‘Ispective’ with the panel fitted on the crusher to measure its hydraulic pressure, temperature, and stockpile information.
Hamm displayed its new Hamm H7 (i) v10 roller, which according to Hamm officials, has intelligent compaction, higher stability and better traction for working at higher gradients and slopes.
Atlas Copco unveiled its new Dynapac CC 4000-6200VI asphalt rollers, which according to the company, are extremely friendly, and have unmatched ease of operation, excellent visibility and the highest quality compaction. The engines have the latest emission reduction technology and their performance is enhanced by vibration frequency and an optional active front drum steering system with big offset that takes maneuverability to new levels.
The company also introduced its new CC 1200 VI and CC 950 tandem asphalt rollers. Targeted for small scale compaction work such as cycle paths, small roads and parking areas, the portable rollers have better visibility, ease of transportation, and enhanced performance led by mechanical adjustable offset functions. By adjusting the rear frame to the left by long holes, the operator can get an offset to the front drum. Offsetting the front drum, officials explain, makes it easier to compact close to walls and curbs without the risk of damage to the machine.
Other new products from the house of Atlas Copco were the MB 1650 hydraulic rock breakers with dust-proof and blank firing protection systems. The breakers can be mounted on 19 to 32-ton excavator platforms.
Gomaco displayed its new Commander-3 series of concrete pavers that have a self diagnostic system and hydraulically extendable tracks. Gomaco officials said that the paver has the ability to deliver the exact levels of vibration for the right paving quality and as per the specifications of the contractor.
French road construction equipment manufacturer Fayat disseminated information about its new Asphalt Manager Vibration System for its tandem roller. Based on the new vibration systems, vibration in the roller is bi-directional. With Asphalt Manager, the roller can adjust its settings as per the density of the asphalt and its temperature. Asphalt Manager prevents over compaction of the surface as this can result in defect and fracture of aggregates.
Company officials shared information on their new paver technology Cederapids, which facilitates extension of the hydraulic screed. Recent improvements on pavers include better heating of base plate for better transfer of heat and at faster levels by at least 50%, and a heavier screed for uniform laying of asphalt.
