DE202022001002U1 - Stop for craning panel-shaped components - Google Patents

Abstract

Crane shoes for lifting and moving panel-shaped components, characterized in that each crane shoe (1) has a recess (4) into which a corner of a rectangular panel-shaped element (7) can be fitted in a form-fitting manner.

Description

BACKGROUND OF THE INVENTION

A large number of structural elements in construction are panel-shaped, such as wall, ceiling and facade elements, but also prefabricated doors and windows.

In the case of multi-storey buildings, these are usually transported to the upper floors using an external crane, depending on the progress of construction.

This is often done with lattice pallets, which must be available in an appropriate size. Occasionally, however, this is not the case, especially not in the case of really large construction elements.

In some cases, ring eyelets are embedded in the construction elements themselves, which enable safe transport on crane hooks.

However, it is often the case that there is no other choice but to hang the panels in the slings of hoists.

Here, for safety reasons, a second wrapping in the horizontal would be necessary. However, this is sometimes not done because the subsequent release of two intertwined chains or belts is difficult, time-consuming and also dangerous.

TASK

The object of the invention is therefore to provide a quick and safe suspension of plate-like components for cranes.

SOLUTION

According to the invention, this is brought about by the fact that crane shoes to be attached in a form-fitting manner are pushed into the corners of the plate elements. These have threads for lifting eyes, the pre-drilled holes of which are aligned in relation to the pulling direction of the panel weight in such a way that their central axis is directed towards the center of gravity of the entire element.

This ensures that there is always sufficient tension on the crane shoe towards the center of the panel and there is therefore no risk of a panel corner slipping out of the crane shoe.

STATE OF THE ART

• DE202008009877U1 beschreibt eine Vorrichtung für eine Hebeeinrichtung. Die Vorrichtung dient zur Ausrichtung der Lage eines Hebeguts mit einem Verbindungselement, welches die Vorrichtung mit einem Hebeelement verbindet. Als Anschlagmittel dient ein Seil oder eine Kette, dessen Länge über eine Winde verstellbar fest und mit der Vorrichtung im Betrieb in einer Wirkverbindung steht.

There are already several lifting gears for securing lifting loads:

• DE202008009877U1 describes a device for a lifting device. The device is used to align the position of a lifting item with a connecting element which connects the device to a lifting element. A rope or a chain is used as a sling, the length of which can be adjusted via a winch and is fixed and operatively connected to the device during operation.

Furthermore, the device has a base frame on which the connecting element, attachment means and winch are arranged.

DE202010001122U1 describes a load handling device. A chain suspension has a sling with a first shortening device. Furthermore, the invention is characterized by a hoist with a second shortening device, which can be detachably attached to the sling. This allows the usable length to be changed.

With this combination of chain slings, loads can be lifted or lowered, or used to balance the load, since the supporting chain lengths can be controlled individually and the length can be adjusted.

EP3569795A1 describes a device for positioning a transport anchor. In a formwork for a precast concrete part, the lifting anchor is defined with an elongate section, which has an adjoining connecting section. In order to reduce the forces acting on the transport anchor, it is suggested that the attached anchor runs at a beveled angle of less than 90 degrees.

The anchor is mounted at an angle on a payload and has connection means to be able to be connected to a hoist. Due to the selected angle, the tensile forces are distributed in such a way that the material is subjected to less stress and is therefore more efficient. Ropes or chains from a crane hook can be attached to the transport anchors.
