Shifting preferences for tippers and dump trucks

In the mining tippers segment, mostly applied to remove overburden and extracting ores and materials in stone quarries and iron ore and coal mines, demand has shifted from the 4脳2 configuration to the 6脳4 category and, in some cases, to 8脳4 configurations, says Rajesh Kaul, Vice-President and Product Line Head 鈥� MHCV, Tata Motors. 鈥淔or surface movement applications, the shift is to 8脳4, 8脳2, 10脳2 and tip trailers (up to 55 tonne GCW). Customers engaged in construction and surface transport are looking at higher capacity tippers.鈥�

Recently, Tata Motors launched all new high-performance, fuel-efficient 6脳4 tippers with Prima and Signa cabins for surface movement. 

Nowadays, buyers prefer mining tippers with 30-40 tonne payload capacity and dump trucks of 50 tonne, 60 tonne and 100 tonne capacity, says Ravindran.

鈥淲e select dump trucks on the basis of the quantum of material to be handled per month and the total material to be handled during the contract/project period,鈥� says Suman Nair, Vice-President - Plant & Equipments, BGR Mining & Infra. That said, Nair points out that 鈥減rivate players engaged in subcontracts find it more cost-efficient to use 50-tonne dump trucks. Mining majors such as Coal India can use 100-tonne plus trucks.鈥�

Large-scale operations warrant high-capacity dumpers. 鈥淎t Reliance Sasan Coal Mines, India鈥檚 largest pit coal mine, we need 240-tonne dumpers to meet our annual target,鈥� says Sanjay Kumar, General Manager, HEMM, Reliance Sasan Coal Mines. 鈥淭here is a limit to how many dumpers you can operate in a mine without causing congestion and compromising safety. For the sake of safe mine operations, we opt for high-capacity machines.鈥�

鈥淏ased on the type of material to be handled, we check that the gross weight of the dump truck falls within the permissible capacity,鈥� adds Nair. 鈥淚n choosing a bucket for the excavator, we prefer that five to six passes of the bucket should fill the dump truck. For loose material like coal, gravel, etc, we prefer box-type body tippers. For other materials like moderately blasted materials, semi-blasted rock, boulders, etc, we prefer a scoop-type body.鈥�

鈥淚n tippers, we look for the highest possible mileage. Every other feature is secondary,鈥� says Kumar.
