<p>The present invention relates to a mobile rack which can store multiple books in a narrow indoor space. More specifically, the mobile rack is light-weighted to reduce the load applied on the floor of a building by the weight of mobile rack and increase the maximum load capacity of the building. Accordingly, more mobile racks can be installed in the same space. A chain is installed on a rail to prevent the mobile rack from slipping by the weight of the stored books when the mobile rack is moved, and to facilitate moving.</p> |
