Some embodiments provide release apparatuses comprising: a body having first and second mating sections each connected to separate tethers; locking shoes each movable between a first position configured to lock the first and second mating sections together and a second position configured to allow the first and second mating sections to disconnect; an actuator configured to move the locking shoes between the first and second positions; wherein each of the locking shoes comprises a locking surface configured to contact an engagement surface of the second mating section and maintain a position of the first mating section with the second mating section; wherein portions of the locking surface comprise toric geometries that are not in contact with the engagement surface when the locking shoes are in the first position and do not come into contact with the engagement surface as the locking shoes transition to the second position.

Several embodiments of a clamp device are provided for lifting equipment from a first position to a second elevated position. The present devices include a body member and either a door or a clamping member. In one embodiment, a chain member may be received within the body member and the door member may be closed about the body member to secure a chain member therewith in. In a second embodiment, a cord, cable or rope may be received within the body member and secured therein when a clamping member is attached thereto. Eyelets located on the body member may be used to attach various equipment and supplies thereto. A wench or other hoisting device may be used to raise the chain, cord, cable or rope associated with the present clamp devices and the equipment attached thereto to an elevated position.

The invention relates to a load-bearing component (1) for the fastening, lashing, and/or lifting technology, such as a shackle, a snap hook, a hook, or a ring link. The component (1) comprises a plastic-metal composite system (4) which forms at least one load-bearing section (2) and at least one connection section (3). The load-bearing section (2) serves to fasten and/or suspend a load, for example, by use of a fastening device. The component (1) can with the aid of the connection section (3) be attached to an object, for example, to a load or a further component (1). In order to design the component (1) as light as possible while having a high load-bearing capacity, its is according to the invention provided the plastic-metal composite system (4) comprises a core (5) made of fiber-plastic composite (16) extending continuously from the load-bearing section (2) to the connection section (3) and comprising at least one outer shell (8) made of metal material and disposed on the load-bearing section (2) and/or the connection section (3). The outer shell (8) serves to transfer a force acting from the outside upon the component (1) across a large surface to core (5).

A cable rotation blocking system (CRBS) (300) is described herein. The CRBS extends along an axis X between a first end (305) and a second end (303), and comprises a first section provided at the first end (305), the first section being configured to be connectable to a cable (100). The CRBS further comprises a second section provided at the second end (303), the second section being configured to be attachable to a load. With the CRBS described herein, when no load, or a load up to an upper load threshold is attached to the second section, the second section is rotatable about the axis X, relative to the first section, however, when a load higher than the upper load threshold is attached to the second section, the second section is prevented from rotation about the axis relative to the first section.

An improved remote sling release for a crane has a main plate member including an access hole for attaching a main crane hoisting line therethrough, a hook portion located at an opposite end from the access hole and adapted to selectively hold securely or release sling members thereon. Two sling ejector plate members connected to one another such that the ejector plate members are pivotally attached to the main plate member, wherein each of the sling ejector plate member has a sling notch therein adapted to receive the sling members of a hoist pallet therein. A sling access handle member attached to at least one of the sling ejector plate members and used to manually rotate the ejector plate members from an open position for receiving the sling members therein and into a closed position, wherein the sling member are locked upon the hook portion of the main plate member. A remotely controlled solenoid mechanism attached to the main plate member and adapted to unlock the locking mechanism, and a first traction spring member adapted to bias the ejector plate members into the open position and force the sling members off of the hook portion. A remote control mechanism adapted to remotely activate the solenoid mechanism, to force the sling members off of the hook portion.

Device (1) for loading a sea container (51) with an elongated heavy product or a row of heavy products via an open front side of the sea container. The device comprises a vehicle comprising a frame (3) and further comprises an engaging unit (11) provided with engaging elements, and moving means for moving the engaging unit up and down relative to the frame. The engaging unit comprises a subframe which is provided with an elongated lifting arm (12) which extends at least substantially horizontally and which has a free end which is oriented in the direction of movement, on the underside of which lifting arm a number of engaging elements are provided over at least part of the length of the lifting arm in at least one row extending in the longitudinal direction of the lifting arm. The invention further provides a method for loading a sea container with an elongated heavy product or a row of heavy products via an open front side of the sea container, using a device according to the invention, as well as a method for unloading a sea container.

A wire rope entanglement avoidance device includes a guide component including a top portion and bottom portion, the top portion and bottom portion shaped along a curvature, the top portion and bottom portion arranged in rotational opposition along a length of material and adapted to fit around the wire rope and a sheath, disposed at an offset from the guide component, adapted to fit over a dead end of the wire rope.

A system includes a crane and an exchangeable tool. The crane and the tool respectively, include an upper tool connector with tool retainers and a lower tool connector which can be interconnected, e.g. a male and female connector, e.g. the lower tool connector of the tool being embodied as a shank provided with a shoulder and the upper tool connector as a tool clamp with a female, open-centered body. A tool suspension device includes the upper tool connector and a travelling block member. The tool clamp has multiple mobile tool retainers adapted to—in a non-operative position—allow introduction of the shank of the tool from below into the shank receiving passage and—in an operative position—engage below the shoulder of the shank that has been introduced into the passage so as to suspend the tool. The upper tool connector may include a bearing allowing for swivelling of the open-centered body, and e.g. a rotational drive operative between the clamp housing and the female, open-centered body to actively drive said swivelling.
