摘要： A pair of safety stop blocks are welded to opposite sides of the fly section of a construction crane boom. The stop blocks have slide passages to receive the branches of a boom extension or load cable which is looped around an arcuate saddle near the base of the fly section. A pair of stop buttons are swaged to the extension cable branches between the saddle and the two stop blocks and are normally spaced somewhat from the stop blocks to allow the cable to seek an equal loading position around the saddle. The stop blocks carry cable retainer elements near the tops of the slide passages to prevent the escape of the cable therefrom. Should the extension cable fail in any region thereof under load, at least one swaged stop button will be engaged by a stop block of the boom fly section to positively arrest its retractive movement before any damage can occur.

摘要： To resist side deflection and buckling of the top and side plates in larger size multi-section telescopic crane booms, top plate lateral supports for the movable boom sections in the fully extended and fully retracted critical zones are provided to supplement the action of bottom lateral wear pads. The top plate lateral supports include adjustable spring bars on the sides and forward ends of the boom sections and coacting cam pads on the top plates of the boom sections at their forward ends and in the socketing zones when the boom sections are fully extended.

摘要： The pivot shaft for the boom of a large mobile construction crane is located near the upper side of the boom base section and its opposite ends are journaled in heavy bearings mounted on vertical side supports rising from a boom turntable. To lock the boom to the boom pivot shaft for unison rotation in the pivot shaft bearings, a single locking pin is received through registering openings in the pivot shaft and a surrounding hub or pillow block fixed to the boom structure within the confines of an internal box support. A screw-threaded extension on the locking pin engages a nut on the exterior of the boom base section, the nut being floatingly constrained by fixed guide tracks which prevent nut rotation with the threaded locking pin while allowing limited lateral and angular adjustment of the locking pin. A cross axis tethered removable retainer pin carried by the nut prevents backing out of the locking pin from its locking position and can only be inserted in the nut when the locking pin is fully in the locking position. The threaded locking pin overcomes a problem of inaccessibility of the interior end of the locking pin within the internal box support.
摘要翻译： 大型移动式起重机的起重臂的枢轴位于起重臂基部的上侧附近，并且其相对的端部安装在从悬臂转台上升起的垂直侧支架上的重型轴承中。 为了将悬臂锁定到悬臂枢轴以便在枢轴轴承中一致地旋转，单个锁定销通过枢转轴中的对齐开口接收，并且在内部框的范围内固定到悬臂结构的周围的毂或枕块 支持。 锁定销上的螺纹延伸部与动臂基部的外部的螺母相接合，螺母被固定的导轨悬挂地限制，该导轨防止螺母与螺纹锁定销一起旋转，同时允许锁定销的有限侧向和角度调节 。 由螺母承载的十字轴连接的可拆卸固定销防止锁定销从其锁定位置退出，并且当锁定销完全处于锁定位置时，只能插入螺母中。 螺纹锁定销克服了内部盒支架内的锁定销的内端不可接近的问题。
