Kirovets К-744RROM NEW!

New generation model of Kirovets industrial machinery. Power 300 hp. Operating weight 14.9 - 19.0 tons. Four-wheel drive, articulated frame. With hydraulic tow hitch.

Industrial tractor K-744RPROM is a new generation of Kirovets industrial machinery. In this model of Kirovets four key consumer properties were significantly strengthened: 

  • comfort
  • passing ability
  • pull rod
  • efficiency

Significant changes have been made in relation to operator comfort and safety:

  • Visibility of the road and working equipment from the driver seat has been improved.
  • air conditioner and heater in the base model improves the working conditions of the driver.
  • springs significantly reduce vibratory loads.
  • use of the brake chambers with pressure accumulators increases the reliability of the brake system in Case-heater for cold weather operation.
Highest passing ability and pull rod are based on a set of best design solutions:

• Articulated frame,

• four-wheel drive,

• Large equal wheels,

• locking differential,

• powerful turbodiesel

• tractor transmission,

• additional ballasting option,

• set of doubling of wheels

• and low pressure tires.

The improved traction properties and comfort for the operator increased the productivity of the tractor. The use of axial piston pump in the tractor hydraulics, which is in contrast to the gear pump is automatically activated only on demand of the system, allows the tractor to save power and reduce fuel consumption.

The main purpose of Kirovets K-744RPROM industrial tractor and its competitive advantage is the transportation of cargoes in the off-road and in mixed driving conditions: spring thaw, impassable track, frost, snow drifts, etc.

 

Options:
  • PTO
  • Set of doubling of wheels
  • Case-heater
  • Extra ballasts
