Problems solved by technology

[0003] However, WO2016 / 133389 discloses that there are still disadvantages in dismantling the lifting device into components or elements sized such that the device can be transported in a standard sea container
One issue is the large space required to build the lifting gear on site, as the mast and boom must be assembled to their full length on the ground

Embodiment Construction

[0026] exist figure 1 In , the initial positions of some basic elements of the device of the invention for assembling the device from the ground up are shown. figure 1 A base frame 1 is shown with an assembly frame 2 mounted thereon, forming an essential element of the invention. Next to the base 1 with the assembly frame 2 is a counterweight 3 which, like the base 1 , stands on the ground. Since this embodiment involves the assembly of a crane, a counterweight device 3 is applied. Having completed the discussion of this embodiment, another embodiment will be set forth in which no counterweight arrangement is present and the apparatus will be explained as a gantry. which will refer to Figure 12 to Figure 17 show.

[0027] now go to figure 2 , shown in figure 1 The next step of assembling the apparatus of the present invention after the initial situation of the present invention is to arrange the top part of the rear mast 5 and the top part of the main boom 6 respect...

Abstract

Provided is an apparatus for lifting heavy loads, comprising at least one mast or part of such mast, from which a load may be suspended, wherein the apparatus is provided with an erection facility that during erection of the apparatus is invariably positionable on a supporting surface external of the apparatus and equipped to convert the apparatus between a dismantled position and a fully erectedposition.

Description

technical field [0001] The present invention relates to a method and apparatus for lifting heavy loads comprising at least one mast or part of such a mast from which a load can be suspended. Background technique [0002] An example of such a method and apparatus is provided in US 6,279764, which discloses a lifting device assembled from parts or elements, the largest of which does not exceed the size of a standard sea container. Therefore, the above-mentioned lifting device can be transported easily and at low cost, and the time required for assembling the lifting device at the location of the lifting work is short, regardless of the required lifting height and load weight. [0003] However, WO2016 / 133389 discloses that there are still disadvantages in dismantling the lifting device into components or elements sized such that the device can be transported in a standard sea container. One problem is that building the lifting device on site requires a lot of space because the...
