DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator machine. More specifically, the present invention relates to a lifting and lowering machine capable of directly carrying a load to a transporting place at a high place.

[0002]

2. Description of the Related Art Conventionally, when carrying a load to a transfer place on a high place or on a floor, the load carried to the transfer site is mounted on a hoist, a transfer band or a slide ladder so that the loading platform is slidable up and down. Generally, a method is used in which the cargo is lifted to a position close to a transfer site by a lifting machine or the like to reach the load, and then transported by hand to the transfer location from there.

[0003]

However, in the prior art described above, although it is possible to make the cargo reach a position close to the transfer location, the movement of the load from the arrival position to the loading location is high. In a place where the condition of the scaffold is unstable, it has to be transported by hand, which makes the work difficult, and has a problem that the work is dangerous.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and it is an object of the present invention to be able to easily move an installation place and to be close to a transfer place. It is an object of the present invention to provide an elevating and lowering machine capable of further transporting a package that has reached a position in a horizontal direction and directly transporting it to a loading place.

[0005]

Means for Solving the Problems The present inventor has conducted various studies on the lifting and lowering machine of the present invention in order to achieve the above-mentioned object. As a result, a substantially square cylindrical frame was formed in multiple stages. The upper end of the main arm, which is inserted and slid up and down sequentially to be able to adjust the expansion and contraction, and the rear end of the horizontal arm, which is formed by projecting a substantially rectangular cylindrical frame in the horizontal direction, are supported by the support shaft. The arm portion is configured by pivotally supporting the arm portion so as to be freely rotatable in the vertical direction, and the carrier suspension is attached to the rail portion and the horizontal rail portion which are continuously attached along the center line on the back surface of these arm portions. It can be configured to be capable of ascending and descending, and to be able to vertically move and carry the luggage by suspending the luggage carrier on the luggage suspension and operating as a series of operations from ascending movement to horizontal movement and from horizontal movement to descending movement. The present invention has been made based on this finding.
