Description:
Schwing Service Training Manual
All hydraulic pumps for the concrete pump, placing boom, agitator, etc
. are mounted on a distribution gearcase
. When you are driving the truck, the power of the truck engine is transmitted through the truck transmission, through a propeller shaft, through the bottom of the distribution gearcase, through another propeller shaft, and into the rear end(s) of the truck.
When you are operating the unit, the distribution gearcase interrupts the power to the rear ends, and transmits it to internal gears that turn the hydraulic pumps.
Changing between travel and pumping modes is accomplished by means of an air switch in the truck cab.
