Vibratory Drum Assembly
(1) Eccentric weight. (2) Eccentric weight. (3) Drive Shaft. (4) Vibratory motor. (5) Coupling shaft. (6) Vibratory Support.
Vibratory action for the machine occurs at the drum assembly.
Drive shaft (3) is connected to the vibratory motor (4).
Eccentric weights (1) and (2) are connected by the coupling
shaft (5).
The vibratory motor will cause the drive shaft (3), eccentric
weight (2), coupling shaft (5), and eccentric weight (1) to rotate
when the operator has moved the vibratory system to the ON
position. The rotation of the eccentric weights creates the
desired vibratory action of the drum assembly.
