The PMK-M has been designed for general underground use. It has a larger, more powerful engine. Flatter than the PMK-T, the truck has a height of 2.40 m. However, due to its 2.3-m width, they are able to transport the same volume as the comparable PMKT series. The cavity possesses a special tailgate avoiding that material gets lost at up-hill rides. Equipped with high quality Posi-Stop brakes the machines can be switched safely at down-hill rides even in fully loaded condition. Additionally the PMKM possesses a retarder providing wear-free brake application at down-hill rides.
