Ski simulator PROLESKI PRO1 PRO 2 PRO3 PRO3V PRO3D  has a sloping surface on which multi-layered belt with special coating is moving. Movement of the belt is directed upwards the sloping surface in the opposite direction to skiers and/or snowboarders. The instructor with the help of the remote control sets and changes speed of moving belt from calm to extreme slope (maximum speed of movement of the belt is 25 km/h, electronically limited).

For safety the simulator provides smooth start-up and smooth stopping of the belt that prevents skiers from falling and possible injuries. Moreover, throughout all length of the side-fencing along the central plank laser sensors are installed that are connected to the device of emergency stop of the belt.

With the help of the sensors any of the skiers can stop the simulator easily if necessary. Emergency stop of the belt is also provided with the help of infrared sensor, a ray of which is located in the upper part of the simulator and directed across movement of the belt. On the top floor on the entire width of the fence of the simulator there are protective mats which also prevent a skier from the blow in case of falling.

In order the upper working layer of the belt be sliding, it should be moistened with water. Moistening is made on command of the instructor with remote control by using the device of carpet wetting. Moreover, the upper working layer is periodically moistened with a special solution which increases sliding and reduces water consumption.
