Electric Locomotive For Underground Applications - Poland

Ld-31 EM electric locomotive for underground applications is

designed for transport in underground areas of “a” degree of

methane explosion hazard.

The locomotive has a compact monolith construction, with the

operator's cabin situated in the middle part of the machine.

The locomotive cabin has been designed according to the

ergonomic requirements concerning the operator's work-place.

The locomotive is powered by a modern brushless motor with

permanent magnets, which significantly improves the

performance of motor engines, including increased pulling

power.

Speed adjustment and change of direction is achieved

by an electronic inverter.

Each motor set is powered

independently, which enables an operation of the locomotive

even in the case, when one of the motor fails.

Ld-31 EM locomotive has an electric proportional main brake

and a spring-operated emergency and parking brake.

The

locomotive is equipped with a system to check the operator's

efficiency - the so-called dead-man's handle.

An operational

condition of the locomotive is monitored.

When the system

detects some abnormalities, a locomotive is stopped

automatically and the cause of this abnormality is signaled

on the operator's control panel.

Main circuits are powered by 250V DC voltage from traction

network, whereas control circuits, lighting, and diagnosis

are powered by 12V DC voltage from traction or battery.

In

addition to the local control station, there is possibility

of remote radio steering used within the loading or tipping

station.

Technical data

ADVANTAGES

- compact modular construction facilitating transportation

and operational activities in underground workings

- double drive system equipped with brushless motors with

permanent magnets, enabling to reach a high efficiency

- state-of-the-art control system taking into consideration

ergonomic requirements for the operator's work-place

- a possibility of working together with standard transport

units
