摘要： A skid-steer loader implement or bucket having a hydraulically actuated grapple component. The skid steer loader includes a hydraulic cushioning mechanism at one or both ends of the hydraulic cylinder such that the grapple component does not come to a hard stop when it impacts against the implement bucket. The cushioning mechanism comprises a fluid restriction that diminishes return fluid flow as piston nears the end of its stroke thereby slowing the movement. The skid-steer also includes a cylinder guard secured to the end of the actuation rod of the hydraulic cylinder to protect the actuation rod from damage. A widened pivot shaft is provided at the pivot structure between the grapple component and bucket implement for filling the gap therebetween and acting as a barrier to objects that would otherwise be forced therethrough.

摘要： A skid-steer loader implement having a hydraulically actuated grapple component that includes an implement having first and second spaced apart pivot support structures and a hydraulically actuated grapple component pivotally secured to the second pivot support structure. A hydraulically actuated cylinder has one end of the cylinder pivotally secured to the first pivot support structure of the implement and is provided with a moveable piston integrally coupled to an output actuation rod that is pivotally secured at an end remote from the piston to the grapple component. The hydraulically actuated cylinder has supply/return ports adjacent the ends of the cylinder adapted to be alternately coupled to a high pressure hydraulic fluid supply or low pressure hydraulic fluid return. The hydraulically actuated cylinder has valve structure to hydraulically cushion movement of the piston and associated actuation rod as the piston moves past a supply/return port prior to being physically stopped at the ends of the cylinder. The actuation rod is provided with a protective shield to protect the actuation rod surface from hostile environmental intrusions by objects in the vicinity of the actuation rod during actuation. The grapple component includes a pivot shaft portion that is at least as wide or wider than a grapple tooth end of the grapple component. The second pivot support structure is comprised of a pair of bearing support elements spaced apart such that a grapple pivot shaft portion cooperates therewith to create a physical barrier to any material thing that may be gripped between the grapple component and implement.
摘要翻译：一种具有液压致动的抓斗部件的滑移装载器工具，其包括具有第一和第二间隔开的枢转支撑结构的工具和枢转地固定到第二枢转支撑结构的液压致动的抓斗部件。液压致动圆柱体具有圆柱体的一端可枢转地固定到工具的第一枢转支撑结构，并且设置有可移动的活塞，整体地联接到输出致动杆，该输出致动杆在远离活塞的端部枢转地固定到抓斗部件。液压致动缸具有邻近气缸端部的供应/返回端口，其适于交替地联接到高压液压流体供应或低压液压回流。液压致动缸具有阀结构，以在活塞在气缸的端部物理停止之前活塞移动通过供给/返回端口液压地缓冲活塞和相关联的致动杆的运动。致动杆设置有保护罩，以在致动期间保护致动杆表面免受恶劣环境侵入物体在致动杆附近的物体。抓钩部件包括至少与抓钩部件的抓钩齿端一样宽或宽的枢轴部分。第二枢转支撑结构包括一对间隔开的轴承支撑元件，使得抓斗枢转轴部分与其配合，以产生可抓握在抓斗部件和工具之间的任何物料的物理屏障。
