Abstract
A battery operated concrete saw system (10) includes an electric saw (12) and a battery pack cart (14) as well as an electrical cord (62) for facilitating cutting in small places with a battery pack cart at a remote location.
Claims12
A battery power concrete saw system comprising:
- a saw including a frame having a pair of rear wheels and at least one front wheel for facilitating movement of the saw to different locations for use and for movement during use performing a cutting operation;
- an electric motor mounted by the frame;
- a pair of saw arbors respectively mounted on the frame for rotation on opposite lateral sides of the frame forward of the pair of rear wheels, and the saw arbors having a rotational connection to the electric motor to provide rotational driving thereof;
- an actuator for moving the front wheel upwardly and downwardly with respect to the frame to pivot the frame about the rear wheels between an upper idle position and a lower use position that permits cutting of concrete or the like with a saw blade mounted on one of the arbors;
- a cart for supporting a battery pack and including wheels and a handle for moving the battery pack to adjacent a location at which a cutting operation is to be performed;
- and
- an electrical cord for connecting the battery pack and the electric motor to power the saw for use which is facilitated in small spaces by the remote location of the battery pack from the saw.
