Machines for extracting

Machines for extracting from deposit work for underground solid fuel deposits of thermoelectric power plants.
  Working part of the machine, wheel with buckets, placed on take over arm, can make a rotation movement of ± 105º from the direction of the wheel tracks and a lifting and descending movement.
  Excavated material from deposit will be deposited by conveyors from the take over arm and discharged on the stationary conveyor from the ground.
  Power is supplied through cables that are coiled up on cable drum of power and control devices in case of the translation movement.
  Combined machine with wheel take over, buckets and stacking is used for depositing material in underground store facility of thermoelectric power plant and for extracting the material from this deposit when it is needed.
  Take over and stacking arm can make a rotation movement of 110º compared with the direction of the rail tracks and a raising and descending movement. Operations of stacking and taking over can be executed in both sides of the rail track, along the store.
  Electric power supply is made with cables that are coiled up on cable drum of power and control devices in case of the translation movement
  Excavator ESRc 130 is equipment used for digging irrigation canals in medium and high hardness soils and for mining activities. It is a digging installation on caterpillar-chain, which digs only in the advance direction and with only one rotation direction for bucket rotor. It is also provided with a conveyor that receives and transports for discharge the material that is excavated.
  Irrigation canals that this equipment can dig have the following dimensions: maximum width 25m (at the level where the equipment is working), maximum depth 5m and maximum width at the base of the canal 5m.Power voltage: 380V
  Pressure on soil: 1, 10daN/cm2
  Moving speed: 6m/min
  Excavator is an equipment used for open-air excavation, especially for brown coal.
  In can be used in open-air excavation for coal, bauxite phosphate as well as for digging large canals and road beds for unblocking escarpments, to extract building materials, anywhere are needed large quantities of material to excavate and manipulate.
  It is an installation on caterpillar-chains with a rotor that carries buckets, with two conveyors belts for taking, transporting and discharging excavated material, with a coal hammer mill, with an intervention and maintenance crane.
