Beschreibung
Zusammenfassung:	A drum unloader may include a pump assembly, a motor, a plate, a piston-cylinder assembly, and a sensor. The motor drives the pump assembly. The plate is mounted to the pump assembly and includes an inlet to the pump assembly. The piston-cylinder assembly includes a housing, a piston, and a piston rod. The housing defines a bore. The piston is received within the bore and cooperates with the housing to define a first cavity and a second cavity. The piston rod is attached to and extends from the piston such that the piston rod extends through the first cavity. The piston rod is coupled to the pump assembly, the motor and the plate such that movement of the piston within the bore causes corresponding movement of the pump assembly, the motor and the plate relative to the housing. The sensor measures a pressure within the second cavity.
