PROBLEM TO BE SOLVED: To provide a high lift work vehicle having a working platform load detector capable of coping even with a case where a load sensor causes failure, and also inexpensive in manufacturing cost.SOLUTION: A high lift work vehicle comprises an upper support member 35 and a lower support member 39 provided between a vertical post 17 and a working platform 19 and supporting the working platform 19 to the vertical post 17, an intermediate member 31 extending to the working platform 19 side in a cantilever-supported state by joining a base end part to the vertical post 17, and working platform load detection means provided in the intermediate member 31 and detecting a load of the working platform 19 by detecting pressing force of acting from the upper support member 35 in response to the load of the working platform 19, and the working platform load detection means comprises a first load cell 41 and a second load cell 42 vertically arranged side by side by allowing mutual load buttons 41a and 42a to abut on each other.SELECTED DRAWING: Figure 2
【課題】荷重センサが故障した場合でも対応可能であり、且つ製造コストが安価な作業台荷重検出装置を備えた高所作業車を提供する。【解決手段】垂直ポスト17および作業台19の間に設けられ、垂直ポスト17に対して作業台19を支持する上支持部材35および下支持部材39と、基端部が垂直ポスト17に結合されて片持ち支持された状態で作業台19側へ延びる中間部材31と、中間部材31に設けられ、作業台19の荷重に応じて上支持部材35から作用する押圧力を検出して作業台19の荷重を検出する作業台荷重検出手段とを備え、当該作業台荷重検出手段は、互いのロードボタン41a,42aを当接させて上下に並んで配設された第1ロードセル41および第2ロードセル42を有して構成される。【選択図】図2
