OUTRIGGER DEVICE OF HIGH LIFT WORK DEVICE
PROBLEM TO BE SOLVED: To provide an outrigger device used with a high lift work device.SOLUTION: An outrigger device comprises an auxiliary leg attached on a support post of a high lift work device, and is rotatable between a closed leg posture (P1) that brings the auxiliary leg to a posture facing upward along the support post, and an open leg posture (P2) that brings the auxiliary leg to a downwardly inclined posture by reversing from the closed leg posture. With regard to a posture lock device (13) that locks at least the auxiliary leg in the open leg posture (P2), engaged means (11) and engaging means (12) are formed by an open leg lock tooth (17) provided on a fixing arm (15) that rotates integrally with the auxiliary leg, and an open leg lock claw (21) provided on a lock arm (19) pivotally connected swingably to the support post. A spring (22) is provided for rotating and energizing the lock arm (19) in a direction to engage the open leg lock claw (21) with the open leg lock tooth (17).SELECTED DRAWING: Figure 7
【課題】高所作業装置におけるアウトリガー装置を提供する。【解決手段】高所作業装置の支柱に付設された補助脚により構成されるアウトリガー装置であり、補助脚を支柱に沿って上向き姿勢とする閉脚姿勢(P1)と、該閉脚姿勢から反転して下向き傾斜姿勢とする開脚姿勢(P2)との間で回動自在とするように構成し、少なくとも開脚姿勢(P2)とされた補助脚をロックする姿勢ロック装置(13)に関して、補助脚と一体回動する固定アーム(15)に設けた開脚ロック歯(17)と、支柱に揺動自在に枢結したロックアーム(19)に設けた開脚ロック爪(21)により、被係止手段(11)と係止手段(12)を構成し、前記開脚ロック爪(21)を開脚ロック歯(17)に係止させる方向にロックアーム(19)を回動付勢するスプリング(22)を設けている。【選択図】図７
