Komatsu Excavators PC170LC-10
PC170LC-10 Hydraulic Excavator
The PC170LC-10 Hydraulic Excavator is a highly versatile machine for all types of jobs which require a smaller machine with big power. Six working modes including a new attachment/economy mode allow the operator to tailor his machine's performance to the type of challenge he's facing. A new larger cab and heated, higher capacity operator's seat makes the operator more comfortable and productive. A standard rear camera linked to the 7" color monitor panel allows the operator to see what is behind his revolving frame. Using the standard pattern change control valve, the operator can operate his joysticks in the operating pattern he is most comfortable with. Two counterweight options are available to match customer needs. The light option is for easier transportability on a tag trailer, while the heavier option is for greater stability when the machine is equipped with items such as a bucket/coupler/thumb combination.
