A hand-held tamper that reduces or eliminates the strain and fatigue that results when workers use conventional rigid concrete tampers. The ergonomic concrete hand-held tamper embodied in the present invention absorbs tremors produced during the striking impact of tamping to be absorbed by spring action within the handle, preventing the tremors from inflicting blunt force transmission to the worker. The hand-held tamper housing a spring assembly that operatively associates with the tamper base so that both move between an unloaded condition to a loaded condition against the pliable concrete worksurface, whereby the spring assembly absorbs the compressive force associated with the tampering process

A concrete float, float assembly, float adapter and interface, and float vibration apparatus and methods are described. A concrete float has improved surfaces, and structures for controlling flow of wet concrete. An interface such as may be included in a quick attach/release configuration may be integrated on a float, and/or may be added onto a float for quick attach/release of a pivot assembly. Adapters may ease attachment or release of an assembly, and may be an interengaging element, such as a sliding dovetail as an interengaging element, or an adapter may be used to place an assembly in tension to secure the assembly. A vibration assembly may be included and configured to have a low center of mass, can have a user display, an accelerometer, and/or other components. A pivot assembly may be included for easier use by an operator, and may include a user display, quick release mechanisms.

A remote controlled vibration imparting device for a concrete finishing tool includes a case that attaches to a float using standard bolt layouts. A motor housing is suspended in and attached to the case, and the motor housing partly surrounds a vibrator with a support, a rotor with a shaft and weighted body, a bi-directional motor, and a coupler between the shaft and the motor. Also in the case are a variable speed controller and a remote switch, both of which are electrically connected to the motor and a battery located on or in the case. The case further includes a removable lid that attaches to a concrete finishing tool.

A tamp having replaceable tamp plates which, when operatively coupled to a tamp handle, can rotate relative to the tamp handle, or a longitudinal axis of the tamp handle, when in use to better allow a tamp plate surface to conform to the material being tamped, while allowing the handle to be more easily maintained in an orientation desired by the user and while reducing or absorbing shock. The tamp may also include dead blow material such as steel shot or the like to improve the inertia, efficiency and impact of the tamp as it is being utilized, while reducing recoil effects.
