    • A lifting hook, its safety latch and a locking and releasing device of the safety latch are disclosed. The lifting hook includes a hook body having a hook stem and tip. The safety latch has a fastening end and a free latch end, the fastening end of the safety latch being pivotally fastened close to the stem so as to move the safety latch between an open position and a closed position, the safety latch being in its open position substantially against the inside of the hook body in a position that leaves a hook jaw free, while in the closed position the latch end extends across the hook jaw to the hook tip, closing the jaw on the inside thereof. A spring arranged between the safety latch and hook body forces the latch end into the closed position. The locking and releasing device includes a locking and releasing lever that is arranged to turn freely between a turning axle of the safety latch and latch end in the front area of the safety latch and that in its locking position rests against the hook tip and keeps the safety latch in its open position against the inner side of the hook body.
    • 公开了一种提升钩,其安全闩锁和安全闩锁的锁定和释放装置。 提升钩包括具有钩杆和尖端的钩体。 安全闩锁具有紧固端和自由的闩锁端,安全闩锁的紧固端靠近杆枢转地固定,以便将安全闩锁移动到打开位置和关闭位置之间,安全闩锁处于其打开状态 在离开钩爪的位置上基本上抵靠钩体内部的位置,而在关闭位置,闩锁端部延伸穿过钩爪延伸到钩形尖端,在其内部闭合钳口。 布置在安全闩和钩体之间的弹簧迫使闩锁端部进入关闭位置。 锁定和释放装置包括锁定和释放杆,其设置成在安全闩锁的转动轴和安全闩锁的前部区域中的闩锁端部之间自由转动,并且其锁定位置处于锁定位置并且保持 安全闩锁在其打开位置抵靠钩身的内侧。

    • A lifting assembly includes a link member defining a pivot axis and a latch axis. The lifting assembly also includes a latch pin and a jaw member. The jaw member is pivotally coupled to the link member about the pivot axis and selectively fixedly coupled to the link member about the latch axis by the latch pin. The jaw member defines a cam surface. Engaging the cam surface with a load rotates a portion of the jaw member into alignment with the latch axis, such that the latch pin may be received by the jaw member and the link member.
    • 提升组件包括限定枢转轴线和闩锁轴线的连杆构件。 提升组件还包括闩锁销和钳口构件。 钳口构件围绕枢转轴线枢转地联接到连杆构件,并且通过闩锁销选择性地以关于闩锁轴线的方式固定地联接到连杆构件。 钳口构件限定凸轮表面。 使负载与凸轮表面接合使得钳口构件的一部分与闩锁轴线对准,使得闩锁销可以被钳口构件和连杆构件接收。
