A hook assembly can include a bumper assembly and a hook attached to the bumper. The bumper assembly includes a top plate, a bottom plate, and a bumper extending between and connecting the top plate and the bottom plate. A lighting element can be disposed on the top plate, the bottom plate, and the bumper to provide a visual indicator for the bumper assembly. The lighting element can be an electroluminescent device, and can be disposed on an exterior surface of the bumper assembly or in a recess extending into the bumper assembly. A power source and other electrical components can be stored in a compartment in the top plate.

A helicopter-hoist system is described. The system may include: hoist equipment, illumination systems, range-measuring equipment, camera(s), communication systems, display devices, processing/control systems including image-processing systems, and power-management systems. The system may also include a smart-hook for measuring a load on the hook. Based on the measured load on the cable, the lighting may be illuminated in different manners. In another aspect, the system may communicate with display devices, which render images of a mission to helicopter crew members or other observers. Measured parameters appurtenant to the missionsuch as the weight of the load, height of the smart-hook above a surface, altitude of the aircraft, distance between the aircraft and end of the hook, location of the hook in three-dimensional space, forces on the hook and cable, and other mission-critical informationmay be overlaid, or rendered proximate to the real images to provide crew members with a full understanding of a mission.

A hoist system includes a load attaching member a single conductor connecting the load attaching member to a hoist for raising and lowering the load attaching member and single conductor. A sensor is operatively connected to the load attaching member to sense a monitored parameter of the load attaching member. The sensor is electrically connected to a receiving module of the hoist for single wired-transmission along the single conductor from the sensor to the receiving module.

A lifting hook bias angle monitoring apparatus, a vertical hoisting monitoring apparatus, and a mobile crane. One method is that a lifting hook assembly serially connects connecting plates (b3) provided with hinge connection shafts (b2, b4) at two ends to a movable pulley component (b1) which bears a pulling force and a lifting hook component (b7) which bears a pulling force, and is also provided with a biaxial inclinometer (b9) on a platform surface (b8) of the connecting plates (b3) which is perpendicular to a lifting force line of action of the lifting pulley component, so as to detect a real-time lifting hook bias angle, and accordingly be developed into a mobile crane having a vertical hoisting monitoring function.
