Abstract: A compactor includes a plate, a vibration mechanism configured to impart a vibrating motion on the plate, and a housing configured to support control electronics therein and defining a battery receptacle upon which a battery pack is connectable. The control electronics are configured to selectively activate the vibration mechanism using electrical current from the battery pack. A frame extends between the plate and the housing, and a vibration isolator is disposed between the housing and the frame and configured to vibrationally isolate the housing from the frame.

Abstract: A handle for a construction tool includes a lower handle portion configured to be coupled to the construction tool, an upper handle portion coupled to the lower handle portion, a handlebar coupled to the upper handle portion and configured to be grasped by a user during operation of the construction tool, and a vibration isolating joint positioned between the handlebar and the upper handle portion. The vibration isolating joint isolates the handlebar from vibration transmitted to the upper handle portion from the construction tool. The vibration isolating joint provides a first degree of freedom to the handlebar relative to the upper handle portion and a different, second degree of freedom to the handlebar relative to the upper handle portion.
