There are the following problems. <A> Since the conventional device is a heavy-duty type, its own weight and shape are large. Depending on the structure of the tip of the crane jib, the mounting position may deviate from the center, and the closer the position of the hanging load and the hanger is to the camera, the more it deviates from the monitor screen. <B> It takes time and effort because the oil balancer needs to be adjusted depending on the undulating speed of the jib. <C> Overall, it is expensive. Especially, the balancer has a complicated structure and requires maintenance cost. <D> In cold regions, the balancer cylinder oil may become stiff and may malfunction.

The TV camera is stored in the storage box 1 for convenience of installation and protection. The storage box 1 is a box with a bottom and a bottom made of, for example, a steel plate, and a viewing window of a lens is opened on one surface thereof. When storing the TV camera, position and fix the lens on the side of the viewing window.

For example, an arm 14 is provided so as to project in a horizontal direction on the side surface of the storage box 1 on the side of the front end lens.
The guide 15 such as a short pipe is fixed to the tip of 4 and the guide 15
Connect the suspension wire-3 through the inside. This completes the installation of the TV camera on the jib tip.

用性を有している。[Effects of the Invention] Since the invention is as described above, the following effects can be obtained. <B> The tail end side of the television camera is swingably connected to the tip of the jib, and the tip lens side is slidably connected to the suspension wire. Therefore, since the television camera swings following the suspension wire, reliable directionality can be obtained. Therefore, the state of the suspended load can always be accurately confirmed. <B> Since the conventional heavy weight and oil balancer are not required, the structure is simple. Therefore, it has a versatility that it can be manufactured at low cost and can be used in a small crane due to its light weight.
