2. Description of the Related Art Large blocks of concrete, asphalt, rocks, etc., which are conventionally generated at construction sites and road construction sites, are very difficult to handle and dispose of due to their shapes and weights. They were abandoned and caused public pollution, which was a major social problem. For this reason, a device for crushing such coarse lumps such as concrete, asphalt, and rocks has been used in a small number of factories.

[0003]

However, such a conventional apparatus used for crushing work is an installation type which cannot be moved because it is installed in a predetermined factory, and is very large.
