lokomotywa akumulatorowa

Application and environmental conditions:

The electric fire-proof locomotive type ELA-44 / * is designed for the transport of materials, machinery and equipment as well as for the transport of people in underground mining plants in workings classified as “a”, “b” or “c” methane explosion hazard and class “A” or “B” of the coal dust explosion hazard.
The locomotive type ELA-44 / * can operate in the ambient temperature not exceeding +40 o C and relative humidity up to 100%.

The electric battery locomotive type ELA-44/1 or 2 or 3 can be operated in the following environmental conditions:


Ambient air temperature:0oC to +40oC
Relative humidity in temp. 40oC:up to 95 %
Height above sea level:-1200÷1000 m npm
Transport and storage:temp. -25oC to +55oC in a short time, not exceeding 24 hours, to 40oC
The air surrounding the locomotive:Free from water and chemically active gases
Environment:Moderately aggressive chemically at best
Installing:The locomotive should be installed in rooms in accordance with the certificate (I M2)
  • the main body of the locomotive,
  • two service cabins with buffers,
  • two wheelsets with gear and engine,
  • flameproof intrinsically safe desk box OISP – built in each cabin,
  • flameproof box of SFIS inverters and controllers,
  • explosion-proof, reinforced construction battery, type SBS-4W or SBS-4WŻ.
  • the ELA-44 / * battery-powered electric locomotive consists of three parts joined together by bolts,
  • these are the main body and two control cabins,
  • such a solution facilitates the transport of the locomotive to the underground mines,
  • booths are equipped with OISP control panels, URO-1 flameproof reflectors, flameproof horns, joysticks (IP65) and other equipment,
  • the main body consists of the chassis and drive (two wheel sets with gear and engine), hydraulic (brake) system and SFIS gearbox,
  • a rechargeable battery of the SBS-4W or SBS-4WŻ type is mounted on the main body.

The electric system of the locomotive consists of the following components:

  • flameproof intrinsically safe desk box OISP (2 pcs),
  • universal flameproof reflector type URO-1 (4 pcs),
  • universal RP-100 spotlight (2 pcs),
  • electric buzzer type KBB-052 (2 pcs),
  • flameproof box of SFIS inverters and controllers (1 pc.),
  • explosion-proof reinforced battery type SBS-4W or SBS-4WŻ (1 pc. + 1 spare),
  • three-phase electric motors of the travel drive, type dSKg 180 L4-EP-f (2 pcs),
  • hydraulic pump motor dSg 90 L4-f (1 pc.),
  • system for the operator identification and recording of the speed and working time of a locomotive.

The entire braking system of the locomotive consists of three completely independent braking systems.
These are:

  • hydraulic brake – maneuvering-emergency,
  • electric brake – electric braking by motors with energy return to the battery,
  • mechanical – parking brake.
