A leveling lifter for a precast concrete slab is provided. The leveling lifter includes an engagement part embedded in a concrete slab, wherein the engagement part extends down to the base and contains a coupler component. The lifter may also include an actuator that is structured to engage the coupler within the concrete slab. The lifter also has a base configured under the engagement part. The base is configured to releasably couple to the concrete slab by projections set at a distance from one another on the base, the projections being configured to detach from the concrete slab in degrees upon engagement of the base by the actuator.

A lifting tool used during lifting and mounting of a rotor blade on a rotor hub of the wind turbine which facilitates repositioning of the crane's main wire. Thus, a lifting bracket, having an elongated element with a first through-going outlet configured to take up a part of a first link, which is connected with the main wire, and a second through-going outlet configured with a spherical bearing to take up a part of a second link on the load, and wherein the elongated element adjacent to the spherical bearing is provided with a measuring instrument with a signal transmitter for registering the angle between the lifting wire and the vertical direction, wherein the signal transmitter is configured to transmit a signal containing measurements for visualization on an external unit with a screen placed at the crane operator and/or near the crane supervisor.

Anchors and precast concrete structures including anchors are provided. An anchor includes a disk having a first dimension D.sub.1, a second dimension D.sub.2 and a first aspect ratio [D.sub.1/D.sub.2], wherein D.sub.1 and D.sub.2 are oriented perpendicular with respect one another, and wherein the first aspect ratio [D.sub.1/D.sub.2] is in a range between and including 0.75 and 1.25; and a head extending from a generally central portion of the disk in a direction generally perpendicular to D.sub.1 and D.sub.2, the head having a third dimension D.sub.3, a fourth dimension D.sub.4 and a second aspect ratio [D.sub.3/D.sub.4], wherein D.sub.3 and D.sub.4 are oriented perpendicular with respect to one another, wherein D.sub.3 is parallel with respect to D.sub.2 and D.sub.4 is parallel with respect to D.sub.1, and wherein the second aspect ratio [D.sub.3/D.sub.4] is less than 0.5.

A masonry anchor comprising an anchor member having a socket formed in one end, the socket being configured to receive and secure a mounting portion of a mounting fastener.

The present invention relates to a faade element and a rail for faade elements. The faade element comprises a frame and faade material. The frame is provided to surround and hold the faade material. The frame has an upper side with a length (L) and an elongate recess with an undercut that extends at least along a major part of the length (L) of the upper side of the frame. The recess with the undercut is adapted to receive the rail in a locking engagement, such that when the rail is in an engaged state a L-shaped engagement portion of the rail is inserted in the recess of the frame and a shoulder of the rail rests on the upper side surface at one side of the recess and a locking mechanism of the lifting rail rests on an upper side surface at another side of the recess.

A lifting anchor assembly that is configured to be embedded in a tilt-up concrete structure includes an anchor member that has a pair of legs extending downward from a central portion of the anchor member to form a generally inverted U shape. A spacer is disposed at a lower end portion of each of the pair of legs, where the spacers each include a plurality of spacing arms that extend radially at different lengths from an engagement portion of the spacer that adjustably attaches at the anchor member. The engagement portion of the spacer is configured to engage the anchor member in different rotational positions to selectively position one of the plurality of spacing arms in a downward position for accommodating different thickness dimensions of concrete structures.

There is disclosed a lifting attachment for a building unit comprising sheeting and a support structure over which the sheeting is disposed, the attachment being configured such that it can be connected to or integrated into the support structure and comprising a lifting anchor that, when the attachment is so connected or integrated, is engageable by a component for lifting the unit such that a releasable interconnection between the component and the support structure passes through an opening in the sheeting.

A lifting insert, particularly for embedment in the edges of thin concrete elements is disclosed. The insert has a head at one end which has a through aperture for the connection of a co-operating lifting link and another end for embedment within the concrete. The head of the insert has an interior region bounded on each side by an exterior region which extends to the longitudinal edges of the insert. The exterior region is thicker than the interior region and the boundary between the two regions defines an abutment surface. The thickness and width of the interior region is dimensioned to allow the lifting link to be connected to the head of the insert and the thickness of the outer region is dimensioned so as to restrict the rotation of the lifting link when a load is applied normal to the axis of the insert, and to effectively transfer the load by a couple developed across the full cross-section of the insert e.g. when tilting the concrete element from a horizontal position to a vertical position.

A lifting and leveling assembly configured to be embedded in a precast concrete slab for lifting a leveling a precast concrete slab includes a base plate, a threaded sleeve, an anchor plate, a thread protecting sleeve, a threaded lifting bolt and an end cap. Rotating the threaded lifting bolt in a first direction positions a bolt head on the threaded lifting bolt above a top surface of a precast concrete slab to accommodate the attachment of a lifting device. Rotating the threaded lifting bolt in a second direction positions the bolt head beneath the top surface of the concrete slab and causes the threaded shaft to exert a force on the base plate to level the precast concrete slab.

There is disclosed a lifting attachment for a building unit comprising sheeting and a support structure over which the sheeting is disposed, the attachment being configured such that it can be connected to or integrated into the support structure and comprising a lifting anchor that, when the attachment is so connected or integrated, is engageable by a component for lifting the unit such that a releasable interconnection between the component and the support structure passes through an opening in the sheeting.
