A BOOM UPLOCK DEVICE FOR A LOADER
Abstract The invention relates to a boom uplock device for a loader where and where the boom of the loader is pivotally fastened to the front body, and the said boom uplock device comprises at least one elongated, cylindrical locking pin and a support for supporting the locking pin. The support is fastened to the front body, and the support has an essentially horizontal through going aperture, in which aperture the locking pin is movably fitted. There is formed a helical guiding groove into the surface of the locking pin, which helical guiding groove is in touch with a steering piece to control the movement of the locking pin, so that when the locking pin is rotating around its longitudinal axis the locking pin at the same time moves in its horizontal direction to enable contact between the locking pin and the underside of the boom to prevent the downward movement of the boom and keeping the boom in an elevated position, or to disable contact between the locking pin and the boom to allow the downward movement of the boom. The invention also relates to a loader. (Figure 2) 1 >1 Olt-I 1 I) ~joorr N Lfl r1 r1
