LocoPro is making headway in green energy utilized in small mining equipment for more than 15 years. 15 years ago LocoPro used the asynchronous motors for the locomotive drive for the first time and since then LocoPro is continuously developing and improving the driving abilities of the electric driven locomotives. In the last three years we made huge engineering development in the means of utilizing customized battery solutions (Li-On and LTO technology) and independent automatic locomotive (train operation).

The TAL Locomotive (Trolley Accumulator Locomotive) is hybrid locomotive that can safely operate in rail slope up to 1:500 and can operate in conditions from -20 ºC to + 45 ºC. The TAL locomotive is a single cabin locomotive and its range can vary from 25-33 tonnes weight. The chassis is constructed for two-axle operation per locomotive.

The locomotive is driven by two independent asynchronous traction motors – one for each axle. The traction motors are mounted to the gearbox via direct drive coupling system. The wheelset is mounted in journal bearings and assembled to the locomotive chassis.

Technical description

Locomotive traction is controlled by two frequency inverters (for each traction motor), with internal independence between the axles for performance and maintenance purposes. The frequency converters take advantage of AC tractions full capabilities and ensures smooth starting and braking of the locomotive.

The secondary energy source is the customized LTO traction battery system.

The locomotive has two independent braking systems. The primary braking system is electrodynamic which either charges the batteries or dissipates heat through the rheostatic brake resistor. The second brake system is a mechanical friction brake that applies its braking force directly to the wheel tread.

The locomotive features a local Locomotive Motor Controller (LMC) so that the locomotive can be driven by a driver onboard but also integrated in fully automated systems. The TAL locomotive can be used as a single vehicle or can be connected via several sources in a master-slave configuration (one on each end of the locomotive).
