Not your run-of-the-mill machines

Bell Equipment South Africa introduced the Bomag range of cold milling machines to its customers at a two-day presentation and demonstration at Bell’s Jet Park facility in Gauteng. Plant Equipment & Hire was on site to see the new machines in action.
German company Bopparder Maschinenbau-Gesellschaft mbH, better known as Bomag, manufactures soil, asphalt and refuse compaction equipment, as well as stabilisers and recyclers. After its acquisition by French company Fayat Group in 2005, Bomag added asphalt pavers and cold planers to its product range.
Bell Equipment is the official southern Africa distributor for the Bomag range of road construction and compaction equipment. At a recent two-day presentation and demonstration at Bell’s Jet Park facility in Gauteng, the company introduced the newest cold milling machines in the Bomag range to customers. Bomag has made advances with its cold milling equipment by establishing new technical standards in the areas of milling technology and maintenance, and Bell Equipment believes that the range can bring real benefits to the southern Africa market.

The managing director of Bell Equipment South Africa, Menzi Dumisa, welcomed those in attendance, before handing over to product marketing manager – Bomag, Johan Hanekom, to introduce the new machines. According to Hanekom, Bomag’s range of cold milling machines are the most powerful machines in their class, enabling torque to be transferred efficiently to the milling drum through variable milling and travel speeds.
The Bomag cold milling range comprises seven machines, the five largest of which will be offered by Bell, representing the machine sizes most prevalent in the southern African region. These range from the compact BM1000/35 with a working width of 1 000mm, up to the powerful BM2200/60 with a working width of 2 200mm. The cold planers feature above average working depths of up to 330mm in one cut, with perfect, clean edges.

The planers are equipped with a long, powerful conveyor belt that is height adjustable and can be pivoted left and right by 45 degrees to provide high flexibility in combination with the truck. The conveyor belt is hydraulically folding for easy transportation, while inner and outer conveyor belts can be quickly disassembled to make maintenance easier. Compact design, coupled with manoeuvrability, makes these Bomag machines an ideal choice for the removal of road and floor pavements under confined conditions, and they are equally capable on arterial roads.
Bomag’s planers also boast features such as external cooling and filtration of the gear oil, while the use of high quality materials maximises the life of the machines and the components. Extended crawler tracks improve traction and stability, in combination with low wear, and the machines have a transport speed of 7.5km/h to reduce unproductive time.
The BM1000/35 features six-cylinder MTU Series 1000 inline engines that deliver 260kW, and is capable of milling up to 3 000m2 per day. The 1 000mm width makes the machine particularly suitable for milling secondary roads, as well as for use in the inner city and at crossings. The maximum milling depth of 330mm and the lateral arrangement of the milling roller allow milling right up to the curb or walls. For this purpose, the rear right-hand track drive can be fully automatically swivelled to a position in front of the milling drum.

Ease of maintenance
Longevity and low maintenance are two key Bomag design principles that are geared towards reducing service costs and non-productive time. This has been achieved through highly visible markings on service points and by ensuring that all components for servicing are well positioned and freely accessible. This applies to tanks, service points in the engine compartment, and work on the milling drum.
“The Bomag design engineers have thought of everything,” says Hanekom. “Tanks for water, diesel, and oil are not welded to the frame, to reduce mechanical loads and make them easier to replace. The power belt cover is divided into two parts so that it can be serviced by one person, the engine oil level is quick to check, the air filter is quick to change, and the water system is easy to access. Clearly arranged components also make the planers quick to service and there are large stowage compartments for tool boxes close to service areas.”
All Bomag milling machines come equipped with the BMS 15 exchangeable tool holder system, which has a very slim design. This gives less resistance in the ground, which translates to less wear and also lower fuel consumption. “However, one of the major advantages of the Bomag machines is the speed and ease with which tool holders on the milling drum can be changed compared to competitor machines. The Bomag drums are also interchangeable with other similar OEM products,” he adds.

Effective noise insulation helps to eliminate operator fatigue. The BM1000/35 boasts a fully enclosed and noise-insulated engine compartment, where the operator sits protected against dust, noise, and vibration. The swivel seat can be slewed 45 degrees to provide excellent visibility of the site, cutting edge, and haulage vehicle. A clearly designed control panel supports the driver with automatic functions and operating aids, while the controls have been clearly arranged for easy operation.
An operator is able to change between three application-specific settings — Eco/Torque, Universal, and Speed — for the milling speed, by using a single three-stage switch on the front panel. Set for the required milling depth, the milling drum always works in the optimum torque range and travel speed is automatically maximised to deliver the best surface quality, fastest possible work rate, reduced consumption, and minimised wear.
“Since launching globally in 2013, Bomag has over 100 cold milling units working worldwide, and the introduction by Bell is in direct response to our customer needs. We are excited by the opportunity to broaden our road construction product offering and thereby strengthen our commitment to our customers to improve their operational and maintenance costs in a highly competitive market,” says Hanekom.
