<p>The telescopic platform has a number of sections fitting with clearance one below the other. The separate sections rest on the floor solely by means of flat supporting surfaces; and can be slid with the aid of one or more lifting trucks, which shift them once raised. Each section can comprise two or more columns with a seat between them, each column having horizontal side portions under which the lifting truck forks engage. These portions can be at heights increasing from the lowest to the highest section, so as to fit alongside each other.</p> |
