The present disclosure relates to a foldable truss boom section, a truss boom and a crane. The foldable truss boom section includes: two chords that do not intersect with each other; at least two slideways fixedly disposed on each of the two chords, wherein each of the at least two slideways has at least two slideway fixing points; and at least two long web members connecting the two chords, wherein each of the at least two long web members has at least one sliding end which is slidable along the slideway and connected to the slideway at one of the at least two slideway fixing points, so that a cross-section state of the truss boom section is changeable.

System, apparatus, device, kit, method and associated technique for safely and securely lifting wall and other structures to a vertical position. An electronic winch device that when connected to an end of a wall structure lifts the structure. A keeper or catchment such that when the electronic winch has hoisted the wall structure to a substantially vertical position, catches and keeps the wall structure in place, allowing the technician to more properly secure the wall structure. The apparatuses are also designed for portability and collapsibility, with structural members telescoping inside one another to minimize size in transport but securely configurable when extended and locked into place.

A fall protection device configured to retain and prevent the fall of a connecting pin used for an end-to-end assembly of two frame elements of a structure, the fall protection device includes a clamping collar having at least one internal groove, configurable between an open position capable of authorizing the insertion of an enlarged head of the connecting pin, and at least one closed position capable of locking the enlarged head inside the internal groove. The device further includes a lock cooperating with the clamping collar to lock the clamping collar in the closed position and a mooring link anchored on the clamping collar to moor the device on a fixed element.

Described is an attachment device (1) for telehandlers (100) designed to be connected to an operating arm (101) and comprising a front frame (12) designed for removably attaching an accessory (102) for engaging a load, such as a fork, a side shift carriage, a winch or a loading platform.

The frame comprises two lateral sides (121) and two crosspieces (122), of which one upper and one lower, which join the side elements (121) to each other.

One or more crosspieces (122) have an oblique inner side (120) relative to a horizontal plane.

Disclosed is a knuckle boom crane, for offshore application, the knuckle boom crane including a crane house, a knuckle boom carried by the crane house, a component for operating the crane house and the knuckle boom, and a controller for piloting the operating component. The controller include a active compensation module that is designed to pilot the operating means, taking into account data coming from a motion reference unit, in such a way as to stabilize a downstream end of the jib, advantageously in a horizontal plane and/or a vertical position, still preferably in all directions.

A combination of a first unit and a second unit are to be rotatably interconnected through a pin. The first unit includes a first unit body provided with a first pin hole, a first contact member, and a fastening member. The first contact member has a first contact surface. The second unit includes a second unit body provided with a second pin hole, and a second contact surface. The second contact surface is contactable with the first contact surface. The fastening member fastens the first contact member to the first unit body so as to allow the relative position of the first contact member to the first unit body to be adjusted.

Disclosed is a knuckle boom crane for offshore application, wherein the crane includes a knuckle boom, carried by a support structure and equipped with an operating unit. The knuckle boom includes a main boom and a terminal boom. The operating unit of the knuckle boom include at least one downstream linear actuator, arranged between the main boom and the terminal boom, for the rotational operation of the terminal boom about a downstream articulation axis. And the at least one downstream linear actuator is fastened to one of the lateral faces of the main boom and to one of the lateral faces of the terminal boom, in order to provide an improved lever arm between the main boom and the terminal boom.
