ことを目的とする。As shown in FIG. 7, when the crane driver's seat 4 is viewed from the lower side to perform the position adjustment, hoisting, and hoisting operation of the hanger, the driver 3 places his upper body forward. He bends down to monitor the lower part through the lower visual window 6c, and this cramped posture is frequently repeated during driving, which easily causes fatigue and distracts attention. On the other hand, with crawler cranes, truck cranes, wheel cranes, etc., when operating the tilting jib from the operator's cab installed on the vehicle body to lift and lower the load from the ground to a high place, the driver controls while looking diagonally upward from the window You have to operate the board and still have the same problem. The present invention solves the above-mentioned conventional problems and enables a driver to operate a crane in a comfortable posture, thereby reducing fatigue and improving safety. The purpose is to provide.

正面の視野を妨げなくし得る。In the crane operation assisting apparatus of the present invention, the reflecting mirror widely captures the visual field to be viewed from the driver's cab downward or diagonally upward with a slightly larger mirror, and the center of the visual field is reflected and projected to the center of the visual mirror. A visual mirror is installed on the front of the driver's seat with an average sitting height or slightly lower height so that the tilt angle can be adjusted by means of a motor or the like around the horizontal axis.
The driver can manually make a remote adjustment with a push button or the like on the control panel to move the visual field in the front-rear direction to the position of the eyes of the driver so that the driver can see the visual field. With respect to the horizontal field of view, the driver can easily view the left and right fields of view on the viewing mirror by slightly moving the head to the left and right. If a little visual training is reduced, the driver can perform frontal visual driving in a comfortable posture for driving in a direction that is difficult for visual driving such as downward or diagonally upward. By making the mirror surface of the visual mirror parallel to the line-of-sight direction, the front view can be prevented.

とができる。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A crane driving assist system according to the present invention will now be described with reference to the drawings. FIG. 3 is a view showing a first embodiment of the present invention. 10 is an average viewpoint height 11 of a driver sitting in a driver's seat 4. At a slightly lower position, a visual mirror provided on the front side of the driver's cab, on the window frame portion, etc., by a horizontal shaft 12 so as to be able to adjust the tilt angle, and 13 sufficiently covers the visual field 14 below the lower window 6c of the driver's cab 1. Using a slightly larger mirror,
It is a reflection mirror fixedly attached to the support part 15 in the upper part of the driver's cab so that a is reflected and projected onto the center of the visual mirror 10. As shown in FIGS. 4 and 5, the visual mirror 10 operably supports a horizontal shaft 12 integrally attached to a rear portion of the mirror with a bracket 16 to a support bracket 17 fixed to a front window frame through a bearing, and one of the support brackets is supported. A motor 18 provided on the motor 17 is provided so as to adjust the tilt in the forward and reverse directions.
Reference numeral 8 enables the driver 3 to adjust the mirror angle by driving the driver 3 on the driver's seat 4 with a push button or the like on the control panel 5. Driver 3
Sit in the driver's seat 4 and look straight ahead in a comfortable posture.
The visual field 14 in the lower direction is viewed on the 0 plane, and the visual operation is performed. By adjusting the tilt of the mirror 10 with a push button or the like at the front, the front and rear parts of the visual field 14 are clearly viewed at the center of the mirror 10, and the hanging tool is used. Operation control such as position adjustment, gripping of a load, hoisting, hoisting, and landing is performed by operating the control panel 5 at hand. Therefore, the conventional cramped work of bending or raising the body for downward visual observation is eliminated, and fatigue can be reduced.

る。Next, FIG. 6 is a view showing a second embodiment of the present invention, showing a case where the operation assisting device for a crane of the present invention is applied to a driver's cab 1 provided on a vehicle body of a crawler crane or the like. The driver's cab 1 is tilted upward so that the front side window can be seen obliquely upward, the reflection mirror 23 is provided obliquely upward in the lower part of the operator's cab for the obliquely upward visual field 24, and the visual observation mirror 20 changes the visual field of the reflective mirror 23. Install it at the bottom so as not to interfere,
The driver 3 sitting in the driver's seat 4 looks at the visual mirror 20 from the viewpoint 11 in a downward direction that is easy for the driver. The structure, mounting method, and relative relationship of the visual mirror 20 and the reflecting mirror 23 themselves may be the same as those in the first embodiment, and in a natural comfortable posture in a sitting position without having to look up at the obliquely upper visual field 24, the diagonally lower front It is possible to monitor and perform visual operation on the visual mirror 20 and obtain the same effect as that of the first embodiment.
