PURPOSE:To reduce the number of bending-down motion times and to increase the efficiency of the work, by a method wherein a pulley is located between a fulcrum and a shoulder band, and a load at a fulcrum is divided into a shoulder and a handle. CONSTITUTION:A band 10 is set on a left shoulder, a band 11 is run around under the right armpit and is engaged with a hook 14, a band is mounted, a handle 1 is swirled by a left hand to regulate the length of a rope to hold it, and a part B is grasped by a right hand. An article, fully loaded in a placing part C, is lifted up by means of the handle 1, and a load on the handle 1 is reduced to a value 1/5 of a load on a fulcram A. In order to change the ratio of a load on the hand and the shoulder, the terminal of a rope 2 is untied, and is engaged with a small ring 6 instead of a small ring 5. This enables a ratio of a load on the hand to that on the should to be freely changed, and enables a work to be carried out in a comfortable attitude through regulation of the length of the rope. |
