MB Crusher has launched the fourth series of its BF120.4 with increased production capacity. The bucket has an operating weight of 4.8 tonnes and can equip diggers with operating weights starting from 30 tonnes. The simplified BF120.4 S4 has a maximum production of 53m 3 per hour, with a load capacity of 1.3m 3 , and has a new centralised lubrication system and lower maintenance costs. New adjustment options have also been introduced, increasing the range of sizes available (from 15mm to 145mm). The bucket has been strengthened where needed, resulting in greater durability and shock-resistance and thus a longer service life. The structural layout has also been upgraded, allowing for faster speeds when handling crushing operations. EvoQuip has launched a new addition to its impact crushing range: the versatile, fuel-efficient Cobra 230 impact crusher, suitable for construction and demolition, asphalt recycling, quarrying, and contract crushing. According to Matt Dickson, EvoQuip product line director, the quick set-up times, simple intuitive operation, and ease of transport make this machine an ideal solution for all applications. The user-friendly hydraulic assist, which comes standard, allows the operator to adjust crusher settings easily without tools. Powered by a fuel-efficient, high-performing direct-drive system, the Cobra 230’s compact footprint makes it ideal for working in urban areas. Ground- level access to the engine, hydraulics, service, and refuelling points, along with hinged radiator pack and hinged diesel tank, ensure easy maintenance. The fourth series of MB Crusher’s BF120.4 offers increased production capacity. Dynapac 10-ton CA255 soil drum roller applications and harsh conditions, compacting most soil types and all base and reinforcement course types. The CA255 is ideally suited for road building, layer works compaction at airfields, ports and harbours, and industrial project sites. The soil compactor features a 50mm drum frame, is drum driven and has a heavy- duty rear axle with failsafe brakes. The hydraulic system The Dynapac CA255 soil drum roller (SDR) is a low- maintenance, fuel-efficient machine that delivers reliable, high-quality compaction to South Africa’s 10-ton market segment. The CA255’s large fuel tank, powerful fuel- efficient water-cooled power unit, and front and rear working lights ensure reliable non-stop operation for long hours in tough Dynapac’s heavy-duty CA255 drum vibratory roller delivers superior compaction performance in stringent environments. 38 _ QUARRY SA | SEPTEMBER 2017 includes a closed-loop hydraulic circuit, and a lowest-in-class hydraulic tank volume further optimises the machine’s efficiency. At 30.9kg/cm, the Dynapac CA255 boasts one of the highest static linear loads in the industry, and offers two different amplitudes: 1.7mm for thicker layers and 0.8mm for thinner layers. The electronically operated vibration reduces resonating frequency, and efficient shock absorbers keep vibrations on the operator’s platform to a minimum. The gas strut-mounted FRP hood can be easily opened and lowered to give complete access to the engine, hydraulics, and service points.
