Battery Powered Hand-Operated Troweling Machine
A battery-powered troweling machine is driven by an electric motor powered by a pair of twenty-four volt batteries coupled in series to drive a planetary gearbox to rotate a trowel blade assembly engageable with the surface of the poured concrete. The controls are carried by a detachable handle that is connectable with a receiver box that traps the handle between interior and exterior stops and uses over center clamps to maintain the handle in proper position within the receiver box. The controls at the rearward distal end of the handle can be used to vary the speed of rotation of the troweling assembly, to adjust the pitch of the individual trowel blades through an actuator and linkage assembly, to initiate actuation of the electric motor and to provide an emergency stop for the operation of the troweling machine.
