Scraper floor motor
125 cm3, drives the scraper floor. Only in QUANTUM 4700 P / S
2073
2-stage motor for scraper floor
Drives the scraper floor. The 2-stage motor contains 2 rotor sets with a displacement of 80 or 95 cm3/rev. = stage 1 and 160 or 195 cm3/rev. = stage 2. 4700S: 80 / 160 cm35800S, 6800S, 5700S: 95 / 195 cm3 Flow rate to rotor set stage 1 (low displacement) generates a high speed but low torque. Flow rate to rotor set stage 2 (large displacement) generates a low speed but a high torque = Start of the unload process.

Hydraulic cylinder for tailgate
Opens and closes the tailgate. As pressure builds up in the rod space, the tailgate is closed.As pressure builds up in the piston space, the tailgate is opened.
3031
Hydraulic cylinder for pick-up
Lifts and lowers the pick-up. As pressure increases in the piston space, the pick-up is lifted.
3042
Hydraulic cylinder for cutting floor
Opens and closes the cutting floor. As pressure builds up in the rod space, the cutting floor is closed.
3084
Hydraulic cylinder for locking the steering axle
Locks the steering axle if pressure builds up in the piston space.
3191
Hydraulic cylinder for hydraulic high-lift drawbar
Lifts and lowers the hydraulic high-lift drawbar. As pressure builds up in the rod space, the hydraulic high-lift drawbar is lifted.
3192
Hydraulic cylinder for proportioning roller ON / OFF
Switches the proportioning roller OFF as pressure builds up in the piston space.
3193
Hydraulic cylinder for pick-up clutch
Switches the pick-up clutch OFF as pressure builds up in the piston space.
