PROBLEM TO BE SOLVED: To provide a power spreader mounting travel carriage which mounts a backpack type power spreader attachably/detachably, can spread a chemical, and improves travel stability, workability and capacity of spreading.SOLUTION: A power spreader mounting travel carriage includes: an undercarriage frame self-standing on fron/rear wheels and travelling an operation handle arranged in a rear side of the undercarriage frame and a mounting part mounting attachably/detachably a backpack type power spreader arranged in an approximately center of the undercarriage frame. The power spreader mounting travel carriage can spread a chemical in a chemical tank of the backpack type power spreader with the backpack type power spreader mounted on the mounting part. The chemical tank of the backpack type power spreader is an approximately rectangular parallelepiped. When the backpack type power spreader is mounted, the longest side of the rectangular parallelepiped forming the chemical tank is parallel to a travel direction of the carriage. The chemical tank is arranged within the undercarriage frame when viewed from an upper side.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】背負式動力散布機を着脱可能に搭載して薬剤を散布することができる動力散布機搭載走行台車において、走行安定性や散布の作業性及び能力を向上させる。【解決手段】前後輪で自立して走行する車台枠と、前記車台枠の後方に設けた操作ハンドルと、前記車台枠の略中央に設けた背負式動力散布機を着脱可能に搭載するための搭載部とを備え、前記搭載部に前記背負式動力散布機を搭載した状態で前記背負式動力散布機の薬剤タンクの薬剤を散布することができる動力散布機搭載走行台車であって、前記背負式動力散布機の薬剤タンクが略直方体であり、前記背負式動力散布機の搭載時に、前記薬剤タンクを形成する直方体の最も長い辺が前記走行台車の進行方向と平行であり、かつ前記薬剤タンクが上方から見て前記車台枠内に収まっていることを特徴とする。【選択図】図1
