Tipper Trucks

Tipper trucks manufacturers continue with their heightened preparedness to introduce newer, cost efficient products on the backdrop of demand becoming firmer. P.P. Basistha reports.

The Indian rigid dump trucks market continues to attain higher traction as demand for hauling granular sub base materials continues to remain buoyant from growing road construction sector. Development of newer coal mines and expansion of the existing ones are also contributing to the rising demand. Manufacturers are actively looking to tap the off take through placement of more advanced equipments which, in particular, minimize operating costs and deliver faster uptime. The business strategy for meeting demand through delivering products with longer, cost effective lifecycle is being done by launching entry level products. The new products come at a premium and deliver higher productivity. According to industry estimates, spurt in demand for the newer tipper trucks units is projected to take the market volumes close to 45,000 units in 2016 up from 35,000 units in 2015.

Mahindra Trucks & Buses Limited (MTBL) has launched its new 'Blazo' range of rigid dump trucks. The new range comprises of tippers, haulage and tractor trailers. Sharing details, Mr. Nalin Mehta, Managing Director and CEO, Mahindra Truck and Bus Division, Mahindra Trucks & Buses Ltd. says, "The new tippers will be delivering higher levels of fuel efficiency with higher capability to perform in combined mode applications. This is as per the present requirements of the Indian quarry owners."

He explains, "The 'Blazo' series is equipped with the 'Fuel' smart technology. CRDe engine is behind this technology. The attribute of the engine is the multimode drive feature, usually seen in passenger cars. The modes are turbo, heavy and light. The modes can be switched by the driver as per the load and road conditions. The uniqueness about this product is ability to change power at switch of button. Based on this, the series offers 274 HP power when pulling power is required especially for quarry operations. The same vehicle can deliver 220 HP for aggregate transportation. This will enable delivering higher fuel efficiency, optimally enabling the truck for usage in combined mode applications, resulting in maximum utilization."

He elaborates, "Our current range of engines mPower were conceptualized with varied applications in mind. We offer 7.2 L engine which has been optimized for all platforms ranging from haulage to tipper. In order to make it suitable for varied applications, we have different power bands starting from 170 HP & going upto 274 HP. For quarry operations, which require high torque at low rpm, our engine would be highly suitable offering the most optimum combination of fuel efficiency & power efficiency. Generally, one requirement is sacrificed at the altar to meet another requirement. In mPower we have taken care to ensure that in quarry operations, both parameters are effortlessly operating at optimum levels."

MTBL's existing Torro and the new Blazo range of tipper trucks can efficiently tip the load without compromising the stability of the vehicle while it is working in undulated conditions, informs Mr. Mehta. "Quarry conditions are highly uncertain and would vary largely from site to site. We have carried out extensive trials to arrive at an ideal combination of wheel base, tipping body locations etc. This is to ensure that stability isn't comprised in an operating condition. Our testing and design offers us the confidence to offer higher cubic capacity bodies which increase the productivity of vehicle contributing to large savings."

Claiming further that the tippers can deliver required tractive effort while working in quarry sites he adds, "Tractive effort is a combination of several aspects which would include engine power, gear ratio & rear axle ratio apart from tyre types. We offer different kinds of combinations depending upon the application. mPower engine offers torque upto 960Nm, which is best in class. This has been suitably coupled with bigger gear box which would ensure adequate pulling power at wheels for smooth movement of loads even in quarry condition, featuring muddy sloppy and rough terrain conditions".

Taking cognizance of the growing demand from the granular sub base haulage from the road construction sector, Volvo trucks will be looking to expand its footprint in the segment. "We are closely monitoring the develo- pments in the aggregates haulage sector. Based on the rising demand, we will be exploring the possibilities of entering into this segment," says Mr. G.V. Rao, Director, Product, Brand & Marketing, Volvo Trucks.

However, the company's focus will be to expand and retain its presence in the mining sector, where it claims to maintain a sizeable presence. It will look to strengthen its presence through offering newer solutions in the sector. "We have maintained between 60-65 percent business share in the coal overburden haulage in the mining sector. This has been possible with our well packaged aftermarket service, ensuring timely parts availability, maintenance and training at the remote mining locations allowing higher uptime of our tipper trucks. Select areas of remanufacturing support have also allowed us to build up our presence."

Volvo FMX

He continues, "Dovetailed with our highly efficient product support is our highly reliable and fuel efficient solutions that has enabled us to maintain our business share. Our most vital attribute that has gone towards making our trucks highly productive and fuel efficient making them highly suitable for overburden removal is our I-Shift transmission. With the automatic intelligent gears, the drivers can focus on his core driving operation. This also contributes towards reducing fatigue making him more productive. Overall it provides the trucks with high levels of traction in the poor underfoot conditions at the mining site. Seeing the encouraging response of I-shift transmission, we will be looking to increase the penetration levels of thesolution in other segments as well, making it a standard offering in near course."

Volvo offers FMX 440 HP 8x4 tippers with 19.5 cum body, FMX 480 HP 10x4 with 24 cum body, and FMX 520 HP 10x4 with 26.1 cum body for overburden haulage. For coal haulage it offers FMX 440 HP 8x4 tippers with 33 cum body.

Mentioning about the response of FMX 520 HP 10x4 launched during previous Excon, with retractable rear wheels for better tractive effort and fuel efficiency, Mr. Rao says, "We have placed some pilot vehicles for trials at the coal mining sites in North India and the response of their performance have been encouraging. We now propose to deliver the trucks for the indexed applications."

He adds, "We have whole range of hauling solutions for the coal mining sector across the value chain. Two of our recent introductions include water sprinklers for dust suppression and fuel tankers on 8x4 platform. We will look for introduction of newer specialized solutions to provide further value to our mining customers.
