A power tool stand comprises a base; a projecting frame connected to the base; and a power tool carriage moveably mounted on the projecting frame. The power tool carriage comprises a first interface arranged to electrically connect with a removeable power tool and a second interface in electrical connection with the first interface and arranged to electrically connect with a removeable battery.

A lift device includes an implement including an implement frame including a base portion and an upright portion extending upward from the base portion, a tool interface configured to be coupled to a tool, and an arm coupled to the base portion of the implement frame and the tool interface and configured to reposition the tool relative to the implement frame. The lift device further includes a chassis, a tractive element coupled to the chassis, a drive motor coupled to the chassis and configured to drive the tractive element to propel the lift device, an end effector interface configured to removably couple to the upright portion of the implement frame, and a lift assembly coupled to the chassis and the end effector interface and configured to raise the implement and the end effector interface.
