<p>The equipment (1) has a ladder structure forming two columns (2, 3) including two storing spaces. Lower spaces (4, 5) and higher spaces (6, 7) are provided in the storage spaces to receive loads and to move the loads vertically inside the columns. A vertical displacement mechanism i.e. tilting system (8), of the loads utilizes potential energy of a full load (9) during its descent with the higher spaces towards the lower spaces for mounting an empty load (10). Ends (11, 12) of the tilting system include reserve units (13, 14).</p> |
