摘要： The present disclosure provides a backhoe boom lock for engaging a hook member of a boom in a transport position. The boom lock includes a pair of side members disposed parallel to one another along a substantially horizontal axis, each side member having a first end and a second end. A transverse member is coupled between the first end of the pair of side members, the transverse member is configured to engage the hook member in the transport position. The boom lock further includes a pivot point defined near the second end of the pair of side members, the pair of side members being pivotally coupled with respect to the pivot point such that the boom lock pivots about the pivot point. A flange is disposed between the second ends of the pair of side members and is further disposed outwardly from the pivot point at an angle with respect to the horizontal axis. The boom lock also includes a counterweight body integrally coupled to the second ends of the pair of side members.

摘要： A backhoe boom lock for locking the boom to the swing frame during transporting and craning operations. The boom is provided with two upwardly open hooks that project on either side of the swing frame when the boom is retracted into its craning or transport positions. Two bell cranks are located on each side of the swing frame and are provided with transverse catches for engaging the upwardly open hooks. The bell cranks are biased downwardly by springs. A linkage for lifting the bell cranks against the biasing force of the springs extends from the bell cranks into the interior of the operator's cab. The linkage is provided with a control lever, located inside the operator's cab for lifting the bell cranks. After the boom has been retracted into its transport or craning position, the control lever is released and the bell cranks rotated by the biasing springs so that the catches engage the upwardly open hooks on the boom.

摘要： A tractor-loader-backhoe is disclosed wherein the loader mechanism is mounted on the frame of the prime mover by a tapered pivot pin having a fastener extending entirely through the axis of the pivot pin to effect a clamping load operable to seat the tapered pivoted in the conical hub affixed to the frame of the prime mover to assure a firm fastening of the loader mechanism on the prime mover. The backhoe mechanism is provided with a transport lock remotely accuatable from the operator's cab mounted on the prime mover and incorporating a locking pin having a concentric spring mounted thereon to urge the pin out of engagement with the frame whenever the transport lock is disengaged to permit operation of the backhoe mechanism. The boom and dipper members of the backhoe mechanism are constructed from a pair of opposing C-shaped channels having inwardly directed legs centrally located within the boom and dipper members. The opposingly facing channel members form a longitudinally extending seam to facilitate welding of the two channel members constructing the boom and dipper members.

摘要： A backhoe loader has a rearward backhole mechanism having a swing frame pivotally connected to a tractor main frame on a pair of vertical pivots. A backhoe boom is swingable on a transverse pivot carried by the swing frame by actuation of a hydraulic cylinder, and the booom being swingable between rearward operating positions and a generally upright transport position. The boom is lockable in its transport position by a mechanism that includes a T-shaped latch member that is swingably mounted on the swing frame on a horizontal pivot, the swinging movement being controlled by a control lever and cable system actuable from the vehicle operator station. The lock includes a pair of upwardly open hook-type lock elements on the boom that respectively receive lock pins formed by the cross portion of the T-shaped latch member, and the hook elements having inclined ramps at their forward ends that engage the latch member pins as the boom swings rearwardly into its transport position to shift the latch member upwardly until the pins clear the ramps and drop downwardly into the sockets of the hook-type elements. An adjustable stop is provided on the swing frame for engaging the boom and limiting the rearward movement of the boom past the upright transport position.

摘要： A releasable boom lock located between a swing tower that pivotally supports a boom consists of a latch pivoted on the swing tower and a pin located on the boom. The pin and latch are designed to automatically interlock the boom and swing tower when the boom is moved to a transport position and are separable from each other by manipulation of a tool fluid ram pivotally supported on the boom. The tool fluid ram has an extension held in a fixed position so that operation of the fluid ram, which causes it to pivot on the boom, will move the extension into engagement with the pivotable latch and release the boom from the swing tower. The extension can be released to be pivotable on the ram to allow operation of the ram without releasing the latch.
摘要翻译： 位于枢转地支撑起重臂的摆动塔之间的可释放的吊杆锁由枢转在摆动塔架上的闩锁和位于吊杆上的销钉组成。 销和闩被设计成当悬臂移动到运输位置时自动地联动起重臂和摆动塔，并且通过操纵枢转地支撑在起重臂上的工具液压缸来彼此分离。 工具流体冲头具有保持在固定位置的延伸部，使得使其在悬臂上枢转的流体冲头的操作将使该延伸部移动到与可枢转的闩锁的接合中，并将悬臂从摆动塔上释放。 扩展件可以被释放以在冲头上枢转，以允许冲头的操作而不释放闩锁。

摘要： Locking apparatus encloses and frees an end portion of a shaft for rotation at a first position of the apparatus relative to the shaft. The locking apparatus further encloses, engages, and prevents rotation of the shaft end portion at a second position of the apparatus relative to the shaft. Respective ends of the apparatus are oriented toward the shaft at the first and second positions. The first position of the locking apparatus permits rotation of the shaft and the second position prevents shaft rotation and related movement of associated implements.
