Haul Trucks
Medha focuses exclusively on zero-emission vehicles in the mining sector. We perform the powertrain and battery sizing design analysis to meet operational needs, as well as design, manufacture and collaborate and build systems to integrate the zero emission kits in to OEM vehicle body.
Haul trucks that operate in a surface mine to carry ore, coal, overburden can be broadly classified as per below from a Battery Electric perspective.
(i) 90 t to approx. 136 t having Diesel mechanical propulsion
(ii) 136 t to 275 t having Diesel electric propulsion, and
(iii) Ultra haul trucks: 275 t and above having Diesel electric propulsion
Medha’s electric powertrain and energy storage system kit caters to the full spectrum of sizes, variance and capacity of the above mining vehicles.
Medha undertakes Battery Electric conversions of existing mining vehicles as well. We customize the zero-emission conversion to bespoke needs of the customer. Customers can be rest assured of the success and satisfaction of the conversion as we are both the manufacturer of the electric powertrain and the integrator as well.
