Doosan Portable Power and Montabert at Bauma Africa
Doosan International South Africa (PTY) Ltd will be presenting a selection of products from Doosan Portable Power (DPP) and Montabert on stand no. H5.301 at the inaugural Bauma Africa exhibition.
Doosan Portable Power are manufacturers of portable compressors and mobile lighting systems for the African market. The portable compressor range is said to be one of the most comprehensive available, with free air deliveries from 2-45m3/min (70-1,600 cfm) and operating pressures of 7-35 bar (100-500 psig). Complementing the wide selection of Tier-3 high-ambient models in the range are 14 Tier 1 or Tier 2 engine-powered models, particularly suited to compressed air applications in the African market.
Visitors will be able to see the popular 7/41 compressor, which supplies 4.0m3/min (140 cfm) of compressed air at 7 bar and is one of a number of models that can be equipped with an integral 6.5kVA generator to provide complementary electrical power for lights, tools, pumps and fusion welding.
Like all DPP compressors, the 7/41 model is ‘built to be used’ providing the highest level of durability, productivity and serviceability. Well-positioned fuel tanks featuring large size fillers limit the risk of fuel spillage. All models have, as standard, an LAT (limited ambient temperature) of 46 degrees C. For applications in hot climates, the high ambient option offers an LAT of 52 degrees C.
Security features include a lockable canopy and lockable steel instrument panel cover. In addition, a folding lift bail reduces the risk of theft by keeping the lifting eye within the compressor enclosure. There are also customer-livery and laser-etching options for the canopy that can provide a further deterrent to theft. An optional built-in storage compartment offers the space to house tools, again reducing the risk of theft and simplifying transport requirements.
New light tower for African markets
Alongside the 7/41 compressor will be the new 50Hz LSC (LightSource Compact) portable light tower, designed specifically for use in African markets. Applications include lighting on road and bridge construction sites, general construction and rental applications as well providing lighting for special events, emergency and disaster relief, oil and gas drilling and for mining and quarrying locations.
Also available as a 60Hz model, the LSC light tower has a new power train based around the Kubota D1005 water-cooled diesel engine providing 8.5kW at 1,500 rev/min (1,800 rev/min for the 60Hz version). Thanks to a high output alternator, the power rating of the LSC light tower has been increased to 6kW. The additional power allows operators to fully utilise the light tower’s four 1,000-watt metal halide floodlights at the same time as using the unit’s receptacle power function. The fuel tank capacity allows an extended runtime of 64h (55h for the 60Hz version).
Of particular interest for the rental industry, the compact frame maximizes loads for transporting on trucks; 12 fully assembled units can be accommodated on a standard 48ft flatbed trailer.
Hydraulic breakers and drifters
Key features of the display of equipment from Montabert will be the company’s range of hydraulic breakers and hydraulic drifters for drilling applications.
At Bauma Africa the focus will be on the Silver Clip range of light hydraulic breakers for carriers ranging from 700kg to 7 tonnes. Demonstrating the easy to use, high-performance and reduced maintenance design of the Silver Clip range, the SC36 hydraulic breaker is intended for use on carriers with weights from 4-10 tonnes. The SC36 breaker has a frequency of 1,550 blows/min and an oil flow of 55-100 litres/min.
Designed for trenching, concrete demolition and general excavation work, an important feature of the Silver Clip range is the cylindrical design of the breakers, which provides easy access to internal and external components, whilst preventing overheating to ensure high productivity and uptime. The breakers also incorporate a very effective soundproofing system, whereby the striking assembly is held top and bottom by suspension systems that are not in contact with the outer cylindrical housing.
In addition, Silver Clip breakers present a completely new internal design with fewer moving parts and no tie rods. As a result, the breakers can be completely disassembled in less than five minutes, without the need for special tooling, reducing maintenance costs even further. Another feature of the Silver Clip range is the patented treated steel ring system, the ‘Clip’, which retains the bushing of the tool and protects the greasing system. This ring can be easily removed with a multi-purpose tool supplied with the breaker, to release the sliding bushing and the tool instantly.
Montabert hydraulic rock drills or drifters combine a percussive system and a rotative system to drill holes into rock. The percussive system strikes the drill steel at 2,000 to 5,000 strikes/min. Simultaneously, the drifter provides a rotation from 100-400 rounds/min. With these two movements combined to provide low torque, high rev/min and high frequency, Montabert drifters are able to very efficiently drill holes into rock.
The HC 109 drifter model from Montabert will be on show. Weighing 142kg, the HC 109 drifter has an overall length of 1,095mm and is suitable for producing holes of 64-102mm diameter. The HC 109 drifter is also suitable for tunnelling and benching applications.
