WheelDozers are powerful machines used primarily for ground movements operations and cargo hauling operations. The machine consists of a tractor, a chassis that supports on the ground that can be a system of wheels or a system of chains or truck and a trailing blade. Within the product catalog of the LSyM group you will find both types of dozers.

Although the most common task is to push large quantities of materials to a heap, excavators are also used to perform floor cleaning and tearing, excavation, refilling and road construction.

Wheeldozers are more appropriate than caterpillars for jobs with greater distances, faster and on dry and hard terrain. It reaches higher speed than caterpillars and behaves badly on muddy, rocky terrain.

The wheels of this machine are not directional, the rotation of the machine is carried out by means of the frame jog, by means of two hydraulic cylinders (while one cylinder lengthens the other shortens)

Why use the Wheeldozer Simulator of LSyM?

The use of the simulator developed by the LSyM group provides the operator with the optimal training to perform tasks such as:

  • Cleaning and sorting of terrain.
  • Push of loose materials.
  • Leveling of terrain.
  • Excavations in a straight line.
  • Formation of piles or heaps.
  • Realization of earthworks.

In addition you will get the necessary skills to avoid or know how to act in situations of risk such as:

  • Hitting, trapping, bumping and collision with or against vehicles.
  • Entrapment of persons in an articulation.
  • Collisions with objects.
  • Fires.
  • Thermal and / or electrical contacts.
  • Rollovers.

Instructional design

One of the highlights of our wheeldozer simulator is the complete instructional design that it possesses, the student thanks to him will overcome exercises until completing the optimal training to operate with this type of machines.

The user of our simulator can perform, among others, the following exercises:

  • Test questions.
  • Basic Driving.
  • Driving on ramps.
  • Circuits with obstacles.
  • Parking.
  • Material push.
  • Reduce stacked material.
  • Basic cutting operations.
  • Material push on ascending / descending slopes.
  • Groove grading.
  • Trench filling.

Reports at the instructor's console

  • Starting and ending time of the session.
  • Date.
  • Time length of session.
  • Finished exercises.
  • Control handling log.
  • Velocity log.
  • Collision log.
  • Dangerous maneuvers log.
