摘要： A boom lock having an actuator and a hook assembly locks a boom of a work vehicle to a swing frame. The hook assembly is pivotally coupled to the swing frame and comprises two hooks and an actuator plate. The hook assembly has a locked position wherein the hooks contact a catch assembly located on the boom and an unlocked position wherein the hooks do not engage the catch assembly. The hook assembly is moved between these two positions by the actuator. The actuator is provided with a fork having an upper tine that contacts the top surface of the actuator plate and a lower tine that contacts the bottom surface of the actuator plate. The actuator is pivotally mounted to the vehicle by a bracket and is provided with a latch for latching the actuator in a first or second position.

摘要： A boom assembly is provided for a material handling machine. The boom assembly includes a boom pivotally coupled to a frame of the machine. The boom has a pair of side plates, a top plate and a bottom plate that are rigidly interconnected. The top plates have a pair of slots which extend therethrough. An arm is pivotally coupled to an end of the boom. A mounting unit extends between a center portion of the side plates. A pair of hydraulic boom cylinders are coupled between the frame and the mounting unit. A pair of spaced apart arm cylinder mounting plates are rigidly mounted to the mounting unit. Each mounting plate extends through a corresponding one of the slots. An arm cylinder is connected between the mounting plates and an arm.
摘要翻译： 提供了一种用于材料处理机器的动臂组件。 起重臂组件包括枢转地联接到机器的框架的起重臂。 动臂具有刚性互连的一对侧板，顶板和底板。 顶板具有一对延伸穿过其中的槽。 臂可枢转地联接到动臂的端部。 安装单元在侧板的中心部分之间延伸。 一对液压动臂缸连接在车架和安装单元之间。 一对间隔开的臂筒安装板刚性地安装到安装单元。 每个安装板延伸通过相应的一个槽。 臂架连接在安装板和手臂之间。
