This utility model discloses an auxiliary electrical interlock for a handcart, including an operating panel disposed at one end of a grounding operating rod. The end of the grounding operating rod has a connection hole for connecting to an operating handle. The operating panel moves relative to the grounding operating rod within a set range, forming a locked or unlocked position to block or open the connection hole. A micro switch for a propulsion mechanism is disposed on one side of the operating panel. In the locked and unlocked positions of the operating panel, the micro switch for the propulsion mechanism is triggered to open and disconnected to close, respectively. This utility model uses an operating panel, operating rod, and micro switch for the propulsion mechanism to form an interlocking structure. The locking and unlocking actions of the operating panel and operating rod in relation to the manual operation of the operating handle are linked to the micro switch for the propulsion mechanism, ensuring that the electric propulsion mechanism cannot operate when the operating handle is not removed or the manual operation state of the operating rod is open, thus ensuring the electrical safety requirements are met.

In some implementations, a system (10) for agitating and excavating material is described. The 5 system may include a compressor unit (56) for supplying a flow of oil-free compressed air by an oil-free compressor; a controller (46) to control the compressor unit; a power supply (38) for powering the controller and the compressor; a hand operated air lance (68) having: a fluid inlet (121) for receiving the compressed air; and an air jet (13) for directing the compressed air into a stream for agitating material. In addition, the power supply, compressor unit and 0 controller may be housed in a stand-alone unit (101) that is manoeuvrable by hand and fluidly coupled to the hand operated lances.

A method of hands free auto-filling of one or more water reservoirs of a liquid dispensing apparatus in which one or more conditions of the liquid dispensing apparatus indicative of the position of one or more float valves operably associated with the one or more water reservoirs of the liquid dispensing apparatus is sensed to determine if the one or more water reservoirs have been filled. A water dispensing assembly preferably includes a liquid manifold, a cold water reservoir, a dispensing nozzle, a pump head, an outlet port supplying water to a hot water reservoir and / or a venting assembly including a vent port and a float valve. Movement of the float valve from a position where the vent port is open to a position where the vent port is closed varies at least one condition of a liquid dispenser during filling of the one or more reservoirs enabling hands free auto-filling.
