Montabert hydraulic rock drills or drifters combine a percussive system and a rotative system to drill holes into rock

A number of exciting products from Doosan Portable Power (DPP) and Montabert will be on show at this month’s Bauma Africa show in South Africa, including portable compressors, new light towers, and hydraulic breakers and drifters.

DPP has one of the most comprehensive range of portable compressors in the industry, with free air deliveries from 2 to 45 m³/min (70 to 1600 cfm) and operating pressures from 7 to 35 bar (100 to 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 (and Middle East) markets.

On show will be DPP’s popular 7/41 compressor, which supplies 4.0 m3/min (140 cfm) of compressed air at 7 bar and is one of a number of models that can be equipped with an integral 6.5 kVA 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. Security features include a lockable canopy and lockable steel instrument panel cover.

The Silver Clip range from Montabert

Montabert will be focusing on its Silver Clip range of light hydraulic breakers for carriers ranging from 700 kg to 7 tonne. Its SC36 hydraulic breaker on the stand is intended for use on carriers with weights from 4 to 10 tonne.  The SC36 breaker has a frequency of 1550 blows/min and an oil flow of 55 to 100 l/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, while 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 novel 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 is very 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 2000 to 5000 strikes per minute. Simultaneously, the drifter provides a rotation from 100 to 400 rounds per minute.  With these two movements combined to provide low torque, high RPM and high frequency, Montabert drifters are able to very efficiently drill holes into rock.

DPP will also show the new 50 Hz LSC (LightSource Compact) portable light tower, designed specifically for use in African markets.  Applications include lighting on road and bridge construction sites, all 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.
