[Prior art]

 2. Description of the Related Art Conventionally, unloading and carrying of heavy goods is carried out by unloading and carrying machines such as forklifts, wreckers and cranes, which are suitable for the size and weight of the objects to be handled. These machines cannot move in a narrow space and require a large work space. When it is unavoidable to unload and transport cargo in a narrow work space, for example, the cargo is once carried out to a wider place by another means such as human power, or the unloading and transporting machine works by handling the cargo that is an obstacle in the foreground. The work is carried out in an environment where people can do it, and devises ideas for each place.

Further, at a stone wall construction site, a tombstone installation site, etc., the step-up and stacking work of stone materials is a very heavy labor, but if physical strength is required, it can be done manually, so mechanization is delayed, and thus it is avoided to young workers. Due to the aging of workers, it is difficult to work. For this reason, there has been a long-felt need for a simple unloading and conveying machine that can be easily turned around in a narrow space. Therefore, the present inventor has previously proposed a dolly crane (Japanese Patent Application No. 4-60250). However, the dolly can be hung by the crane, but the luggage cannot be lifted from below. However, it took some time to hang it, and some items could not be handled depending on the luggage.
