Features

• Tradition and Innovation

  The new compact mini-excavator is the product of the competence and the technology that KOMATSU has been acquiring for over the past eighty years. The project has been developed with a constant attention to the needs of customers from all over the world; the result is a user-friendly machine, which offers top class performance.
  
  

• Performance

  The new short tail PC50MR-2 supplies optimal power and digging speed in confined spaces: yards, road works, demolition works, sewers, wherever traditional machines cannot work. Sturdiness and excellent stability ensure safety and confidence in any condition.
  
  

• Komatsu CLSS

  The CLSS (Closed Load Sensing System) hydraulic circuit guarantees power, speed and perfect control to all movements, including the combined ones. The main feature of this system is the connection between the variable displacement pump and the closed-centre circuit with load sensing, which allows operators to perform all movements with maximum efficiency, regardless of the load or the rpm. These characteristics are highlighted by the hydraulic servo-controls, which are by far the easiest to use and require minimum efforts to perform extremely precise manoeuvres.
  
  

• Comfort

  Despite its compact size, the PC50MR-2 offers a comfort which has no equals: spacious cab, PPC proportional servo-controls for all movements, sliding door, gas spring assisted front window, storage drawer, hook, cup holder, courtesy lamp and, upon request, radio and air conditioning.
  
  

• Versatility

  Many available configurations allow the operator to choose the right machine for the specific job: short or long arm, cab or canopy, rubber or steel shoes, extra counterweight. Moreover, the 1 / 2 way auxiliary hydraulic circuit consents to use multiple working tools, like the hammer, the clamshell bucket, the auger, etc.
  
  

• Maintenance

  All periodic inspection points are easily accessible through the bonnets. The fuel and the hydraulic oil tanks are located under the side bonnet, in a safe and easy to reach position. In addition, extra-ordinary maintenance can be performed by simply tilting the cab upwards: under the floor, the operator can find all major hydraulic components, like the main valve or the swing motor.
  
  

• ORFS hydraulic face seal connectors and DT electric connectors improve the reliability of the machine and make repairs easier and faster. Special technical solutions have allowed to extend up to 500 hours the intervals for most ordinary maintenance operations, such as pin greasing or engine oil replacement. Also, to avoid possible leakage, all tanks are equipped with a draining hose: this confirms once again the attention KOMATSU pays to the environment.
