Abstract
A multiple-rope or multiple-cable pulling device is provided for positioning a load. The device can include an electronic controller that interprets a user's input from an interface such as a trigger or a joystick, and activates electronically controlled motors that drive one or more rope pulling mechanisms, such as winches. When the winches pull in or pay out cable in accordance with the controller's demand, the load is moved along the desired trajectory as specified by the user through the device interface.
