Until recently tipper trucks were identified as equipments with restricted role to offer dumping solutions. However, passing through enormous innovative technological modifications, tipper trucks are also now offering both cost effective dumping and haulage solutions to the construction and mining industry, reports Partha Pratim Basistha.
Competitive construction solutions are synonymous with advanced equipment features. The solution can become further competitive if inherent features are synthesized with technological advancements. This is what the present generation of tipper trucks is made from.
Bygone is the era of nascent mechanization when role of tipper trucks were grossly restricted to offer dumping solutions. Even then the role of the trucks was modest in construction and mining sector, as their performance were limited to rudimentary features. The new version of tipper trucks have been reengineered completely to its core. They come with better ground clearance, making them to operate well on uneven work sites. The trucks have newer tyre variants with better frictional properties, thus allowing them to be optimally mobile on rough, slush and slippery terrain surface.
Applications DefinedHaving incorporated all technological modifications, tipper trucks are now vehicles that can find its application in diverse construction jobs involving roads projects, power plants, dams, ports tunnels in a big way and industrial development projects.
In road construction projects, there is a requirement of removal of earth all along the earmarked site till the requisite depth followed by laying of multiple layers of materials such as ‘good earth’, Granular sub base, Macadam layers and bitumen mixes. Tippers are used for the transport of all these materials in road construction (road-site to dump and burrow or plant to road-site). In dams, hydropower projects and canal work, nature of work involved is essentially removal and relocation of earth on the sites to obtain the desired profile. This earth movement is done again largely by tippers. In mining projects, tippers are again used to transport the ‘over burden’ material as well as the underlying mined ore from the blast site till the conveyor/dump yard. Tippers are also used in the road transportation of material such as coal once it is mined from the mines in cases where the lead distance to the end site is too long for conveyors and/or rail transport is not an option.
As per a senior spokesman from Tata Motors, “All jobs can be done by the tippers with ease given their advanced features.” He added “With job sizes becoming larger and compressed work schedules, the market for tippers in India is gradually shifting towards vehicles with larger body sizes and more horsepower. There has already been a considerable shift from two axle tippers to multi axle tippers. In a number of applications such as coal, it is predominantly multi-axle vehicles that are used today. In this sense, in future, the percentage of multi axle vehicles is set to rise sharply.”
Further he said, “Tata Motors Limited has products straddled across the entire range of tippers in terms of capacity – ICV tippers, 16 tonnes and 25 tonnes, body options – box and scoop versions, cabin options – semi-forward and full-forward, power – 130 to 230 Hp, suspension – normal and heavy duty as well as special trucks such as tip-trailers. In the 16 tonne range, there are tippers with 160 and 180 horsepower engines with semi-forward and full-forward cabin options to cater to diverse applications and customer preferences. In the multi-axle range, there are tippers from 160 to 230 Hp again with body and suspension options which include the LPK 2518, LPK 2518HD and the LPK 2523. Moreover, we have an exciting new range of powerful and larger multi-axle tippers coming up as part of our Prima range.” The tipper trucks are manufactured at Tata Motors plant at Jamshedpur and Pune.
On sales and customer support, scenario the spokesman informed, that “Tata Motors has an extensive network across the country with around 600 workshops and over 7700 retailers. Spares and Maintenance support are provided to the customer through a number of channels. The extensive network of service centres, dealerships and retailers is the first line of support offered to the customer. Apart from this, there is an AMC facility which the customers can avail of to ensure year round maintenance and service of our tippers. Yet another option is an on-site service package where maintenance personnel and spares are maintained at the customer’s site to ensure timely support for the customer.
As for equipment selection, our sale team studies the nature of the application extensively and consult the customer to ensure best equipment - given the nature and size of the application - is chosen.”
Wide range of tipper trucks are also claimed to be offered from Asia Motor Works Limited (AMW). A relatively new entrant into the tipper market, Gujarat based AMW has wide range of tippers for diverse construction and mining applications.
AMW tipper trucks are available in the 25 to 49 tonne segment. The engine horse power of the tippers is of 180 or 230 HP range.
He says, “AMW mining tippers are ideal for hauling ore, coal, overburden and other geological materials. They are designed to operate on the toughest road conditions encountered in many mines in the country. Most mining sites in the country do not have adequate road facilities and here is where AMW tippers score over competitors. From difficult conditions encountered in open pit mining to transportation from pithead to loading, our tippers are superior in performance, durability and reliability.
Air-conditioned cabin is a standard feature on all AMW vehicles. As per the company, the cabin design provides ample room space and better visibility.
According to Mr. Ramsubramanian, “Our dealer and service network is available 24X7 and at most of the major sites, we have service engineers and stock essential parts to make sure the contractors have minimum downtime we have over 51 dealers across the country. Since service is a key differentiator in this segment, we have mobile service vans, which are a phone call away. These vans are located at every 200 kms or simply 4 hours away for most locations in the country.” AMW tippers are manufactured at its plant in Bhuj, Gujarat.
Powerful variants of tipper trucks are stated to be manufactured by Force Motors Limited, India. Force Motors has entered into a 50:50 joint venture collaboration with Man Nutzfahrzeuge AG of Germany. The new joint venture entity is Man Force Trucks Private Limited.
