Schwenkbar gelagerte Auflagepratze Die vorliegende Erfindung betrifft eine Pratze (10) zum Transportieren von Coils oder Bandringen (20) mit horizontaler Achslage (21), insbesondere aus Eisen-, Nichteisenmetallen oder anderen Materialien wie beispielsweise Papier; mit ei-nem das Coil bzw. den Bandring (20) in dessen Auge (22) aufnehmenden ersten Pratzenabschnitt (auch als Auflagepratze 11 bezeichnet) und einen den ersten Pratzenabschnitt (11) halternden zweiten Pratzenabschnitt (12), wobei der erste Pratzenabschnitt (11) um eine Längsachse (13) der Pratze (10) schwenkbar am zweiten Pratzenabschnitt (12) gelagert ist. Zwecks Rückführung des, im Zuge einer achsversetzten Positionierung der Aufla-gepratze (11) im Coilauge (22) vor Lastaufnahme verschwenkten ersten Pratzen-abschnitts (11) in eine definierte, vorzugsweise horizontale, Ausgangsposition zur Längsachse (13) der Pratze (10) ist erfindungsgemäß zwischen ersten (11) und zweiten (12) Pratzenabschnitt wenigstens ein Federelement (16) angeordnet. Die erfindungsgemäße Pratze (10) schont vorteilhaft und in bislang nicht bekann-ter Weise das Coil bzw. den Bandring (20) bei achsversetzter Positionierung der Pratze (10) vor der Lastaufnahme, und zwar unabhängig davon, ob die Pratze (10) starr oder ggf. klappbar an einem Lastaufnahmemittel (30) angeordnet ist.

A device for moving a load by means of a hoisting crane or the like, which device comprises a hoisting member to be coupled to the hoisting crane or the like, a pick-up element for picking up a load to be moved, as well as a lever which is pivotally connected to the hoisting member about a pivoting point, which lever is pivotally connected to the pick-up element on one side of said pivoting point and which is connected to a ballast on another side of said pivoting point, a special feature being the fact that the device comprises at least one pivoting arm for keeping the pick-up element at least substantially in vertical position, wherein the pivoting arm is pivotally connected to the pick-up element near one end and to the hoisting member near its other end, wherein the pivoting arm is disposed at least substantially parallel to a part the lever extending between the pivoting points of the lever.

L'invention porte sur une cale de basculement (1) qui comprend une jambe (20) permettant d'immobiliser la cale pendant la pose d'une pièce (2) sur cette cale (1).

A bollard setting and installation system for efficiently installing a bollard wall without any restrictions relating to proximity to water or flood plains. The bollard setting and installation system generally includes a setting frame which is positioned on a ground surface. A plurality of bollards is positioned on the setting frame in a desired spacing and orientation to form a bollard wall. A vehicle having a vehicle arm connected to a lifting frame is positioned such that the bollards are secured to the lifting frame by clamps in the desired spacing and orientation. The vehicle may then move the lifting frame to position the lower ends of the bollards in an opening in the ground surface. Concrete may be poured to encapsulate the lower ends of the bollards. The lifting frame may then be removed, with the bollard wall being free-standing in the ground surface.

This invention relates to a bulkhead unit, a wind turbine blade comprising the bulkhead unit, a lifting device and methods of assembling and installing the bulkhead unit in the wind turbine blade. The bulkhead unit comprises a bulkhead element substantially extending in a radial direction and a frame structure attached to the bulkhead element. The frame structure provides support for the bulkhead element and additional components mounted to the frame structure. The frame structure comprises a plurality of frame elements which are interconnected to form a number of areas that are aligned with corresponding openings in the bulkhead element. The lifting device is used to lift the bulkhead unit into position and fix the bulkhead unit relative to the blade shell.

The present invention provides a C-hook comprising a "C" section at one end of which is a prolonged protrude ending at a means to hold counter weight balance, the said prolonged protrude attached with a lifting pin having a lifting ring over the said lifting pin, at the other end of the said C section a coil stopper, a probe attached to the coil stopper for lifting the coil roll. Using this c-hook provides several advantages including ease to place the rolled metal coils in eye to door position.

A balanced cantilevered feeding apparatus for coupling with a jib, and a complementary method for its operation, configured to facilitate depositing and removing of a load through an opening in a building.
