    • A luffing jib backstop assembly for limiting rotation between a luffing jib (30) and a boom (20) to which the luffing jib (30) is attached is disclosed. The assembly comprises at least one backstop pendant (40) attached at a first end (31) to the luffing jib (30) and at a second end (21) to the boom (20), the pendant (40) having a length sufficient to allow the luffing jib (30) to be extended to an angle of 180° with respect to the boom (20). The assembly further comprises a deployable member (60) which engages the backstop pendant (40) and which, upon full deployment, holds a portion of the backstop pendant (40) away from the boom (20) and luffing jib (30) such that the pendant (40) and deployable member (60) prevent the luffing jib (30) from rotating with respect to the boom (20) beyond a permissible operating angle.

    • There is provided a crane (100A, 100B, 100C, 100D, 100E) which can be safely operated in a case where a backstop (70) malfunctions. There is provided a crane (100A, 100B, 100C, 100D, 100E) including a front member (108) capable of derricking and a backstop (70) disposed on a rear surface side of the front member (108) so as to limit a standing operation of the front member (108). The crane (100A, 100B, 100C, 100D, 100E) has an angle sensor (170) that detects an angle of the front member (108), an operation detection unit (80) that detects whether or not the backstop (70) is operated, and a controller (200A, 200B, 200C, 200D, 200E) that controls a derricking operation of the front member (108) . In a case where the controller (200A, 200B, 200C, 200D, 200E) determines that the angle of the front member (108) is equal to or larger than a predetermined angle, based on a detection signal output from the angle sensor (170), and in a case where the controller (200A, 200B, 200C, 200D, 200E) determines that the backstop (70) is not operated (S3/No), based on a detection signal output from the operation detection unit (80) (S6), the controller (200A, 200B, 200C, 200D, 200E) stops the standing operation of the front member (108).

    • A compressible stop member for use on a crane (10) includes: a) a housing (52) having a first sealed end (54), a second end (56) and an internal surface (53) comprising a first cylindrical surface and a second cylindrical surface; b) a free piston (62) slidably contained within the housing (52) in a sealing engagement with the first cylindrical surface; c) a compressed gas chamber (58) in the housing (52) between the free piston (62) and the first sealed end (54); and d) a rod (76) comprising a cylindrical portion with a diameter less than the diameter of the second cylindrical surface and a rod support portion (64). The rod (76) extends out of the second end (56) of the housing (52) with a sliding sealing engagement. The rod support portion (64) is slidably contained within the housing (52), and separates the volume between the free piston (62) and the second end (56) of the housing into a first liquid chamber (57) comprising the volume inside the housing (52) between the free piston (62) and the rod support portion (64), and a second liquid chamber (59) comprising the space between the rod support portion (64) and the second end (56) of the housing (52). Also, the rod support portion (64) includes at least one flow channel (65) allowing liquid to flow between the first and second liquid chambers (57, 59) as the rod support portion (64) slides within the housing (52).
      The compressible stop member is particularly useful as a boom stop (15) for a lift crane (10) having a boom (22) pivotally mounted on a rotating bed (20). The boom stop (15) will engage the boom (22) when the boom (22) reaches a first angle compared to the plane of rotation of the rotating bed (20). Movement of the boom (22) from the first angle to a second steeper angle causes the rod (76) to be pushed into the housing (52), thereby forcing the rod support (64) toward the free piston (62), with liquid flowing from the first liquid chamber (57) into the second liquid chamber (59) as the rod (76) travels, creating an increased volume in the second liquid chamber (59) but a decreased volume in the first liquid chamber (57) and a commensurate increase in pressure in the gas chamber (58) and on the rod support (64), thereby impeding the movement of the boom (22) towards the second steeper angle. If the lift crane (10) includes a luffing jib (23), a separate compressible stop member may also be used as a jib stop (45).
    • 一种用于起重机(10)的可压缩止动构件包括:a)具有第一密封端(54),第二端(56)和内表面(53)的壳体(52),该内表面包括第一圆柱形表面和 第二圆柱面; b)自由活塞(62),其与所述第一圆柱形表面密封接合地可滑动地容纳在所述壳体(52)内; c)在自由活塞(62)和第一密封端(54)之间的壳体(52)中的压缩气体室(58); 以及d)杆(76),其包括直径小于所述第二圆柱形表面的直径的圆柱形部分和杆支撑部分(64)。 杆(76)以滑动密封接合从壳体(52)的第二端(56)延伸出来。 杆支撑部分(64)可滑动地容纳在壳体(52)内,并且将自由活塞(62)和壳体的第二端(56)之间的容积分隔成包括内部容积的第一液体室(57) 自由活塞(62)和杆支撑部分(64)之间的壳体(52)和第二液体室(59),其包括在杆支撑部分(64)和壳体的第二端(56)之间的空间 (52)。 此外,杆支撑部分(64)包括至少一个流动通道(65),当杆支撑部分(64)在壳体(52)内滑动时,允许液体在第一和第二液体室(57,59)之间流动。 可压缩止动构件特别适用于具有枢转地安装在旋转床(20)上的起重臂(22)的起重机(10)的悬臂止动件(15)。 当悬臂(22)与旋转床(20)的旋转平面相比达到第一角度时,悬臂止动件(15)将接合悬臂(22)。 将起重臂(22)从第一角度移动到第二较陡的角度使得杆(76)被推入壳体(52)中,从而迫使杆支撑件(64)朝向自由活塞(62),液体 随着杆76行进,从第一液体室57流入第二液体室59,在第二液体室59中产生增加的体积,但在第一液体室57和/ 气体室(58)和杆支撑件(64)中的压力相应地增加,从而阻止起重臂(22)朝向第二更陡的角度移动。 如果升降机起重机(10)包括变幅悬臂(23),则单独的可压缩止动构件也可用作起重臂(45)。
