摘要： A locking assembly has two members which are moveable into coupling engagement with one another. The two members have lock engaging walls, and one of the members has an opening between the lock engaging walls for receiving a lock. The lock comprises a lock body and a retainer. The lock body has a channel for receiving a portion of the retainer. An end of the retainer extends underneath a retainer engaging wall, thus resisting movement of the lock out of the opening.

摘要： A tree saw includes a frame adapted to be attached to the boom of a prime mover, a tree clamping mechanism on the frame, and a carriage assembly on the frame below the clamping mechanism. The carriage assembly includes a generally plate-like chassis, a generally U-shaped bulkhead upstanding from the chassis and providing a recessed base portion and forwardly-extending arm portions, and a slide mechanism on the arm portions. A rail mechanism on the frame receives the slide mechanism for reciprocating movement of the carriage assembly. A hydraulic cylinder assembly interconnects the bulkhead and frame for reciprocating the carriage assembly. An annular rim member rotatably mounted on the chassis has a geared inner circumference and a toothed outer circumference projecting forwardly of the base portion. A motor-driven pinion mechanism on the chassis engages the rim member inner circumference to rotate the rim member.

摘要： A hydraulic snubber suitable for a skidding grapple or the like in which a twisted figure eight housing is provided to oppose free swinging in two mutually perpendicular horizontal directions, each portion of the figure eight having a cylinder housing with a rotor, each rotor having radially extending vanes. At least one vane has a flexible extension including at least two orifices equipped with a pocket for adjustably limiting the flow of hydraulic fluid to each respective side of the vane. The cylinder housing is equipped with a safety relief valve so that hydraulic fluid can bypass a vane to prevent excessive pressure buildup on one side of the vane.
摘要翻译：一种液压缓冲器，其适用于打滑抓斗等，其中设有扭曲图形八壳体以在两个相互垂直的水平方向上自由摆动，图8的每个部分具有带转子的气缸壳体，每个转子具有径向延伸叶片。至少一个叶片具有柔性延伸部，其包括至少两个配备有口袋的孔口，用于可调节地限制液压流体流向叶片的每个相应侧面。气缸壳体配有安全释放阀，使得液压流体可以绕过叶片以防止在叶片的一侧上产生过大的压力。
