The leftmost is a tall extension ladder with rope-and-pulley mechanism; next is a step ladder with hinged legs and safety braces; the third is a simple straight ladder; and the rightmost is a rare conical ladder with tapered rails for stability on uneven ground. Each design reflects period-specific construction techniques and occupational needs.
