Abstract: A robotic mount is disclosed that attaches onto any appropriate stand, framework, or other support structure. The mount can manipulate the position and orientation of affixed devices upon remote command received from any network connected device. A specific or sequence of positions/orientations can be precisely registered and promptly returned to on command.

Abstract: A hoist provides high mechanical advantage and accurate positioning, driven by hand or with a powered rotary implement such as a drill. The hoist includes flexible tension members, such as chains, cables or straps, for applying force and tension to a load. A load nut is connected to the tension members for high mechanical advantage from rotational drive input to a load screw threadedly connected to the load nut. Alongside the tension members are guides forming channel-like spaces within which the flexible tension members travel. The guides, or portions of the guides, pass through the load nut in most forms of the invention.

Abstract: A safety system for overhead hoisting cranes is provided which incorporates a overload release coupling in the high speed drive shaft between the prime mover and the gear reducers driving one or more hoist drums with a dual reeving and a safety brake acting on the high speed drive shaft at the gear reducers and controlled by an overrunning clutch and a control means.
