[Prior art and problems to be solved by the invention]
A conventional crawler crane has a driver's cab, a hoisting device, a boom hoisting device, a swiveling device, etc. mounted on the upper part of a crawler type traveling device, and their power is supplied from a hydraulic pump driven by a diesel engine to each work device. It is transmitted to the hydraulic motor.
[0003]
Such a crawler crane can perform various operations by changing various attachments. For example, when crane work is performed by a crawler crane, when lifting or hanging a load with a hook, or when tower work is performed as a tower crane, or when excavation buckets are attached to perform ground excavation work, etc. Various operations are performed.
[0004]
When performing various crane operations using such a crawler crane, the operation levers of conventional cranes are floor lever type, and the operation levers are arranged in front of the driver's seat. For this reason, in tower work, the operator leans against the driver's seat and looks up, so that the operation lever is distant. In ground excavation work, the operator gets out to see the front of the machine, so that the operation lever is too close.
[0005]
Therefore, there is known a console box in which an operation lever is arranged in place of the floor lever method and arranged on the side of the driver's seat. The console box will be described with reference to FIG. In FIG. 6A, reference numeral 1 denotes a console box such as a crawler crane. The console box 1 is installed on the side of the driver's seat 2 and, as shown in FIG. Three operation levers 3, 3, and 3 used for, for example, raising and lowering the boom, the first winch, and the second winch are arranged on the front stage of the upper surface (right side in the figure), In the middle stage, for example, one operating lever 4 for the third winch is arranged, and in the rear stage, for example, two operating levers 5 and 5 for traveling are arranged.
[0006]
Thus, the driver 6 selects and operates a required operation lever from among the operation levers 3, 3, 3, 4, 5, and 5 according to the type of work. At that time, since the console box 1 is installed on the side of the driver's seat 2, the driver 6 changes the arm angle to change the front operation levers 3, 3, 3, the middle operation lever 4, and the rear step. The operation levers 5, 5 can be freely selected and operated, and the operability of the operation levers 3, 3, 3, 4, 5, 5 is improved as compared with the floor lever system.
[0007]
However, the operation levers 3, 3, 3, 4, 5, and 5 are located at different positions from the driver 6, and the driver 6 changes the arm angle to change the operation levers 3, 3, 3, 4, 5, and 5 respectively. , 5 can be freely operated, but all the operating levers 3, 3, 3, 4, 5, 5 are in an optimal operating position for the driver 6 such that the arm has an angle suitable for the operation. There are some control levers that are difficult to operate.
[0008]
Further, the knobs 3a, 3a, 3a, 4a, 5a and 5a of the operation levers 3, 3, 3, 4, 5 and 5 have substantially the same shape. In some cases, the driver may look away from the front to look at the hand to check the operation lever, which is extremely dangerous for work.
[0009]
Therefore, in the console box of construction machinery, there is a technical problem to be solved in order to improve the operability of the operation lever and to prevent erroneous operation and improve safety. It aims at solving.
[0010]
