Abstract
A vibratory tamper comprises a roller assembly, a chassis, a frame, and a vibrator. The roller assembly includes a roller drum having a roller surface. The chassis is supported on the roller assembly. The chassis includes a body and a grip. The frame is engaged by the grip of the chassis. The frame includes a handle positioned to be used by an operator to support at least a portion of the frame during operation of the vibratory tamper. The vibrator is supported on the chassis and operable to transfer vibration through the chassis to the roller assembly.

A vibratory tamper comprising
- a roller assembly including a roller drum having a roller surface,
- a chassis supported on the roller assembly, the chassis including a body and a grip,
- a frame engaged by the grip of the chassis, the frame including a handle positioned to be used by an operator to support at least a portion of the frame during operation of the vibratory tamper, and
- a vibrator supported on the chassis and operable to transfer vibration through the chassis to the roller assembly.
A vibratory tamper comprising
- a roller assembly including at least one roller drum having a roller surface,
- a chassis supported on the roller assembly,
- a frame supported by the chassis, the frame including a handle positioned to be used by an operator to support at least a portion of the frame during operation of the vibratory tamper, and
- a vibrator supported on the chassis and operable to transfer vibration through the chassis to the roller assembly.
A manually manipulable vibratory tamper comprising
- a roller assembly including a roller drum having a roller surface, the roller surface configured to engage a surface to be worked by the vibratory tamper with a line of contact,
- a chassis supported on the roller assembly, the chassis including a body and a grip,
- a frame engaged by the grip of the chassis, the frame including a handle positioned to be used by an operator to support at least a portion of the frame during operation of the vibratory tamper, and
- a vibrator supported on the chassis and operable to transfer vibration through the chassis to the roller assembly to impart a working vibration to the surface to be worked through the line of contact.
