The present invention relates to a check device for a crane cab, and more particularly, to improve the work efficiency by allowing the operator to more easily inspect the crane cab and to clean the window, and to prevent safety from falling accidents in advance. It relates to a check device of the crane cab for securing.

In general, crane is a transportation equipment installed in most heavy industry factories such as steel mills and shipyards, and is used to transport heavy goods more efficiently. Remote control using a remote control, or as shown in Figure 1, the driver rides in the cab 1 attached to the lower side of the crane to operate the overhead crane (A).

Crane in the present invention is a known overhead crane (Gantry crane), gantry crane (Gantry crane), bridge crane (Reclaimer), Collector, Unloader, and so on.

In addition, in most factories, a large amount of dust is generated in the atmosphere due to external conditions such as working environment and temperature change. At this time, dust (dust, foreign matter) generated on the surface of the window of the crane (A) cab 1 Since it is difficult to secure the driver's field of view, it is difficult to smoothly and quickly transfer the heavy goods, and in particular, since the heavy materials cannot be unloaded at the correct position, the work efficiency is lowered.

Therefore, in the related art, in order to solve the above problems, a separate wiper is installed on the front window of the cab 1 to remove dust on the surface of the window.

However, the wiper as described above is able to remove the dust on the outside of the window within the operating range, which is to remove the dust on the edge of the windshield outside the operating range of the wiper and the side window without the wiper installed. There is no limit.

In addition, as shown in Figure 2 sitting on the stairs (2) connected between the crane (A) and the cab 1, the operator removes dust on the front and side windows of the cab 1, Since one hand must hold the railing of the stairs, and the other hand must hold the window cleaning tool and remove the dust on the surface of the window. Severe physical strain on the site will have to be the disadvantage.

Furthermore, since the conventional cab 1 does not have a working space (check table) for maintenance and inspection at all, a separate aerial work device (service car) is used for maintenance and inspection of the cab 1. After raising the worker to the position of the cab (1) by using the operator has to proceed with the maintenance and inspection work of the cab (1), as well as the need for a separate aerial work device as well as the need for work The disadvantage is that the rental cost of the device is wasted.

In particular, considering that the cab 1 is installed at a height of approximately 14 to 40 m from the ground, the worker's psychological anxiety (acrophobia, dizziness) for inspection work has been aggravated. Safety accidents that inadvertently fall down have become frequent.

In addition, for the inspection work of the cab (1) must use the aerial work device that is moved from the ground, which will cause a safety accident due to the collision with the equipment, so the maintenance and inspection work after stopping the equipment in operation As a result of this, there is a serious problem that causes economic loss as well as a decrease in production efficiency due to the shutdown of the equipment.

Therefore, the present invention has been made to solve the conventional problems as described above, the present invention forms an inspection device protruding forward from the bottom of the crane cab to the operator to climb the inspection device to clean and check the window of the crane cab It is to provide a check device of the crane cab to increase the work efficiency.
