PROBLEM TO BE SOLVED: To provide a conveying truck having a structure in which the shock on a fixed caster or the like is less influential when a base plate or the like is dropped when derricking and turning the base plate with a small occupied space.SOLUTION: A fixed caster 27 link-connected from a rotary spindle 31 of a base plate is lifted upwardly by turning and derricking the base plate 30 with a base plate supporting shaft 31 fitted to a rear end of a base plate frame 10 as a supporting point. A ground contact surface of the fixed caster 27 is moved from the lower side to the upper side of the ground contact surface of a four-wheel universal caster 26. Nesting can be executed by the operation of the four-wheel universal caster 26. In addition, brake working unit is mounted on a fixed caster base 14 with respect to the vertically movable fixed caster. A brake operation unit is mounted on a fixed caster horizontal frame 13 to achieve a brake mechanism in which the working unit and the operation unit are non-connected to each other. |
