PROBLEM TO BE SOLVED: To provide a small, lightweight drum roller easily mountable by one person to carry out delivery work. SOLUTION: The function of a roller part of a conventional drum roller is united with a structure mountable to a conventional stepladder on the market. Since the stepladder serves as a frame part of the conventional drum roller, only the roller part is required to attain miniaturization and weight reduction. As to the stepladder serving as the frame, since a construction contractor always has it available, it does not become special expenses. The drum roller is mounted to the conventional stepladder on the market, and when lifting a drum, the principle of a lever is applicable. The drum can thereby be easily mounted by one person.
