A utility model consisting of a plurality of ladder parts made of titanium or a titanium alloy, in which the ladder part and another adjacent ladder part slide against each other in the longitudinal direction. In a telescopically connected ladder for high-altitude work, a protective layer is provided on the facing surface of the ladder portion and the adjacent other ladder portion that come into contact with each other when the ladder portion slides, and this protective layer is made of titanium. Or a ladder for working at heights, characterized in that it is made of a solid material that has high lubricity with respect to titanium alloy. 2. A ladder for working at heights according to claim 1, wherein the protective layer is made of a copper alloy. 3. A ladder for working at heights according to claim 1, wherein the protective layer is made of synthetic resin. 4. A ladder for working at heights as set forth in claim 1, 2, or 3 of the utility model registration claim, wherein the protective layer is formed by winding a band-shaped member. 5. A ladder for working at heights as set forth in claim 1, 2, or 3 of the utility model registration, characterized in that the protective layer is formed by adhesive.
