Mining Locomotives

MMT-M-320-BDE

Modular Multi System Production Locomotive

With a total weight of 45 tonnes, this ModuTrac locomotive is designed with a central cab and is currently the heaviest twin-axle locomotive Schalke manufactures. Each wheelset is driven by a 160-kW AC electric traction motor and two state-of-the-art liquid-cooled IGBT-controlled traction converters make it possible to control each wheelset individually. The locomotive is designed with a hybrid power supply system, featuring a pantograph for overhead catenary and Powerpacks for diesel or battery operation. The Powerpacks can be quickly and smoothly replaced in as little as one hour.

This ModuTrac locomotive is equipped with several state-of-the-art traction technology systems and the locomotive features the same high quality Schalke products designed to keep operating and maintenance costs low. These include the electro-dynamic main brake, which is powered by the traction converter and strong enough to bring the entire train to a standstill if required. In cases of emergency or for prolonged parking, the locomotive is equipped with a pneumatic service brake, which includes a spring-loaded function. Moreover, a highly efficient slip-and-slide protection system is used, ensuring the optimal use of available tractive forces, depending, of course, on the wheel-rail friction coefficient. State-of-the-art AC traction technology ensures reduced maintenance costs and standstill period compared with DC systems. A train protection system for outstanding operating safety and a train automation system for driverless operation are also optionally available.

MT-M-900-EEB

Multi System Production Locomotive

This locomotive is designed with an end cab and has a total weight of 108 tonnes, distributed over four axles. Each wheelset is driven by a 225-kW AC traction motor and can be individually controlled, thanks to state-of-the-art, amongst others liquid-cooled, IGBT-controlled traction converter technology. The power can be supplied by various hybrid options, including a vertical pantograph for overhead catenary operation and also a horizontal pantograph for side catenary operation. The locomotive is additionally equipped with Battery-Powerpacks, enabling it to operate without an external power supply. This locomotive is equipped with an impressive range of the latest modular traction technology. In typical Schalke style, the engineering and the carefully selected components keep running and maintenance costs to an absolute minimum. The wear free, electro-dynamic main brake is capable of bringing the entire train to a standstill, for example 1,500 tonnes of unbraked train capacity can be brought from 25 km/h to a complete halt. The electro-dynamic traction technology enables the locomotive to halt briefly or stop and start on ascending slopes without a problem. The pneumatic service brake is equipped with a spring-loaded function and only designed for use in emergencies or for prolonged parking. Further features of this locomotive are its highly efficient slip-and-slide protection system and its state-of-the-art AC traction technology, which also ensures reduced maintenance and downtime costs. The locomotive can be divided into four separate modules to facilitate transportation and assembly underground.

A train protection system for outstanding operating safety and a train automation system for driverless operation are also optionally available.

SMT-M-100-BDE

Modular Production And Service Locomotive

Using a modular system, this small ModuTrac locomotive was developed by Schalke as a new standard vehicle and expands our line of mining vehicles to include a model featuring a comparatively low total weight. It is ideal for use as a production locomotive in smaller mines with lower capacities, but can also be practical for use in larger-scale mines – e.g. as a service vehicle.

Although its design is fundamentally simple, the technology is state of the art and the locomotive itself is extremely durable and long-lasting. This ModuTrac locomotive features highly flexible and modular design to make it suitable for as many locations and applications as possible. From the option to select various distances between axles; from gauge widths between 600 and 1,435 mm. and weights varying between 10 and 20 tonnes, the types and heights of the couplings are just as variably selectable and can be precisely ordered to suit on-site requirements. The power system of the ModuTrac is also highly variable and offers a choice of traction batteries with up to two times 1.125 Ah @ 80 V Ah capacity (2.250 Ah @ 80V total) that provide sufficient power for an entire shift, but also a diesel generator unit with up to 150 kW of power output and a pantograph for straight forward electrical operation via overhead catenary.

In addition to the typical Schalke’s standard of high quality and long-lasting mining products, a great feature of this locomotive is its ability to negotiate even the tightest of curves, even with a radius as small as 17 metres.
