A winch capable of externally connecting motor is to selectively assemble and increase an externally connected motor (a third motor) on a winch driven by a set of motors so that a driving device disposed inside a driving device box of the winch is driven by dynamic power supplied from three motor at the same time to provide greater pulling force and faster pulling rate for a rope wheel of the winch, thereby providing wider scope of application. Moreover, the externally connected motor (the third motor) can be disassembled when there is no need such that dynamic power is provided by two motors so as to save power and energy resource.

A pipe replacement system and cable guide frame are shown. Configurations are shown that include plurality of guide pulleys attached to the cable guide frame to define a curved path between a pipe to be replaced and a cable pulling system. Configurations are shown where a pipe breaking tool is pulled over the plurality of guide pulleys for ease of removal after a replacement operation. Configurations are also shown that include a stationary splitter adjacent to the cable pulling system to prevent jamming of the cable pulling system.

An automatically opening and closing inflatable holiday ornament includes a box that has a base, a plurality of side panels hingedly connected to the base, and a top portion connected to each of the plurality of side panels. The ornament further includes a motor, a plurality of pull cables, such that each of the plurality of pull cables has a first end operatively connected to the motor and a second end connected to one of the plurality of side panels. The ornament also includes a first blower, an inflatable disposed in the box and surrounding the first blower such that operation of the first blower blows air into the inflatable to inflate the inflatable, and a controller operatively connected to the motor and to the first blower such that the controller controls operation of the motor and the blower.

A method and a circuit for controlling electric power delivered to an electric motor are disclosed. A forward control signal is transmitted when a forward command is received while a forward latch is not set. The forward latch is set and the forward control signal is stopped when a power level of the motor exceeds a threshold while the forward command is received. The forward latch is reset and a reverse control signal is transmitted when a reverse command is received. The reverse and forward control signals are not transmitted when no command is received. A reverse latch is optionally set when the power level exceeds the threshold while the reverse command is received. A winch connected to the motor has a cable wound thereon in a forward direction of the motor and unwound therefrom in a reverse direction of the motor, as controlled by the circuit.

The present disclosure discloses a vehicle, a winch for the vehicle, and a warning control device for the winch of the vehicle. The warning control device includes: a warning component; and a warning control board, including: a load detector, connected to the motor through a current sensor, and configured to detect load condition of the motor by collecting measured working current of the motor; a processor, connected to the load detector and the warning controller respectively, and configured to output a warning control signal to the warning controller according to the load condition of the motor; and a warning controller, connected to the warning component and the processor respectively, and configured to receive the warning control signal and to control the warning component to produce a warning based on the warning control signal.

Methods, apparatus, and systems are provided for rigging interfaces couple to winch cable terminals that protect outer surfaces of fairleads and rigging devices as connections between objects. In one example, a rigging interface may include curved surfaces adapted to nest against a fairlead. In another example, a rigging device may have one or more removable elements allowing for coupling of the device to other objects.

A winch hook comprises a hook portion and a loop receiving portion adapted for receiving a loop of a winch line. At least one three-dimensional feature of the winch hook is adapted to engage at least one three-dimensional feature of a fairlead so that the hook engages the fairlead while the hook is in at least four different orientations relative to the fairlead.
