    • A boom stop having a elongated tubular body portion is mounted on the rod end of one of the hydraulic lift cylinders of a skid steer loader. When the boom of the skid steer loader is lifted, the boom stop is carried outwardly with the rod end of the cylinder, the opposite end of the boom stop dropping into a plane adjacent the rod end of the cylinder when the hydraulic cylinder is almost fully extended. Thus the boom stop is interposed between the outer end of the cylinder body and the rod end of the cylinder to retain such lift cylinder in an extended position under loading conditions. A projection provided at a lower end of the boom stop carries a toggle mechanism mounted on a pivotal connection, the mechanism including a ramp like projection which rotates downwardly when the cylinder is extended further outwardly to disengage the stop from the cylinder body, the ramp engaging both the cylinder body and the body portion of the stop to slide the body portion of the stop onto the cylinder body when the cylinder is pulled back to a fully retracted position.
    • 具有细长管状体部分的臂架安装在滑移装载机的一个液压提升缸的杆端上。 当滑动转向装载机的悬臂抬起时,悬臂停止件随着气缸的杆端向外运动,当液压缸几乎完全时,悬臂止动器的相对端部落在与缸体的杆端相邻的平面中 延长 因此,悬臂止动件被插入在缸体的外端和缸体的杆端之间,以在加载条件下将该提升缸保持在延伸位置。 设置在悬臂止动件下端的突起承载安装在枢转连接件上的肘节机构,该机构包括斜面状突出部,当气缸进一步向外延伸以使止动件与气缸体脱离时,斜面接合 当气缸被拉回到完全缩回位置时,止动件的缸体和主体部分都将止动件的主体部分滑动到缸体上。
