PROBLEM TO BE SOLVED: To provide a self-travel type carrier device with a lift function which is capable of reducing the number of components and attaining reduction in weight, can prevent the cost of manufacture from being increased and improves a vibration-proof function.SOLUTION: The self-travel type carrier device includes: a first link L1 of which the upper end is connected to a driven trolley 3 so as to be oscillated around a first shaft J1 and the lower end is connected to a lift frame 4 so as to be oscillated around a second shaft J2; and a second link L2 of which the upper end is connected to a driving trolley 2 so as to be oscillated around a third shaft J3 and the lower end is connected so as to be oscillated around a fourth shaft J4 positioned at a midpoint between the first shaft J1 and the second shaft J2 of the first link L1. The first shaft J1 and the third shaft J3 are positioned substantially within the same horizontal plane, and the second shaft J2 and the third shaft J3 are positioned substantially within the same vertical plane. When the lift frame 4 is lifted by a hoist 5, the driven trolley 3 is moved along a rail R so as to be separate from the driving trolley 2 or close to the driving trolley 2.
【課題】部品点数削減及び軽量化が図れ、製造コストの増大を抑制できる、揺れ防止機能が高い昇降機能付き自走式搬送装置を提供する。【解決手段】従動トロリ3に対して第1軸J1まわりに揺動可能に上端部が連結され、昇降フレーム4に対して第2軸J2まわりに揺動可能に下端部が連結された第1リンクL1と、駆動トロリ2に対して第3軸J3まわりに揺動可能に上端部が連結され、第1リンクL1の第1軸J1及び第2軸J2間の中点に位置する第4軸J4まわりに揺動可能に下端部が連結された第2リンクL2とを備え、第1軸J1及び第3軸J3が略同一水平面内に位置するとともに、第2軸J2及び第3軸J3が略同一鉛直面内に位置する。巻上装置5により昇降フレーム4を昇降させると、従動トロリ3が駆動トロリ2から離反又は駆動トロリ2に接近するようにレールRに沿って移動する。【選択図】図3
