A shackle clamp assembly has one end configured as a cap for insertion on the end of a shackle bolt attached to a U-shaped shackle and second end configured as a loop for attachment around the U-shaped shackle. The cap has an aperture that aligns with a through-bore in the end of the shackle bolt. A pin is inserted through the aperture of the cap and the through-bore of the shackle bolt to retain the cap on the end of the shackle bolt. The cap abuts the nut threaded on the end of the shackle bolt to ensure that the nut does not become disconnected from the shackle bolt.

A load-force-independent triggering device for a load exerting a force on it that is held in a CLOSED position of the triggering device and released in an OPEN position of the triggering device includes: a housing; a triggering lever, which is connected to a triggering gear via a steering lever, the triggering lever being swivel-mounted on a first housing axis, the triggering gear being swivel-mounted on a second housing axis and the steering lever being swivel-mounted on a steering-lever axis on the triggering lever and on a second steering-lever axis on the triggering gear; a spring device acting on the triggering lever; and a locking device, by which the triggering device is fixed in the CLOSED position. The steering lever has an angular design, and, in the CLOSED position of the triggering device, contacts a first contact surface in the housing.

A slingbar includes a sling attachment member. The sling attachment member includes a frame including a base having a top end and a bottom end, and a hook extending from the bottom end to a hook terminus. The hook terminus and the top end of the base define an opening. The hook, base, and opening bound an interior of the attachment member. A closure element includes an outboard gate hinged to the hook terminus and an inboard gate hinged to the base. The gates have a default state in which each gate extends laterally only part way across the opening.

Described herein is a hoisting block for a crane. The hoisting block includes an engaging element such as a load hook, to which a lifting tool such as a sling or a hoisting frame can be coupled. The hoisting block is provided with winches, outgoing winch cables of which are configured to carry the lifting tool to the engaging element and couple it to the engaging element. Also described herein is a crane provided with the hoisting block. The hoisting block can be applied for carrying a lifting tool to an engaging element and coupling it to the load-bearing means, or for stabilizing an engaging element relative to a support structure.

A lifting hook (14) provided with a remotely operated safety latch (12), wherein remote operation is used to both open and close the latch. The latch can be magnetically held (36) in the open position to connect and disconnect the load from the hook. Furthermore, an indicator (42) can be provided to indicate when the latch is latched and unlatched. The latch can be operated with lines with a first line (62) controlling one direction of movement of the latch and a second line (64) controlling a second direction of movement of the latch.

The present invention relates to a lifting device for a crane which comprises a lifting cable winch, a lifting cable and a load-receiving means (10), the load-receiving means (10) being connected to the lifting cable and being movable by means of the lifting cable winch, in particular vertically movable. According to the invention the lifting device has at least one spring mounting (12) so that on the whole the load to be lifted and received by the load-receiving means (10) is mounted in a sprung manner.

A damping mechanism may comprise a housing, a shaft, a spring arm assembly including a first spring arm, wherein the spring arm assembly is coupled to the shaft and configured to rotate in response to a rotation of the shaft, wherein the first spring arm extends relatively radially outward of the spring arm assembly toward the housing in response to the rotation of the shaft, and wherein the rotation of the shaft is damped in response to extending the first spring arm.
