Abstract

A system provides building materials including a packaging, a lifting device and a mixing and conveying device. The packaging can be positioned by the lifting device via the mixing and conveying device in such a way that a total height of the system is less than 230 cm.

First claim

The invention claimed is:

1. A system for providing a building material, the system comprising:
a packaging with a first component arranged therein, the packaging comprising a cover and a suspension device, the cover having a standing surface, at least one side surface, and a top surface, the suspension device comprising loops which are arranged in an upper area of the at least one side surface, and an area of attachment of the loops to the cover is spaced from an upper edge of the at least one side surface by a distance in a range of 5 to 30 cm;
an emptying device formed in the standing surface;
a filling device formed in the top surface;
a lifting device configured to operatively connect to the suspension device of the packaging and to displace the packaging in space; and
a mixing and conveying device configured to mix the first component with a second component to form the building material and to convey the building material therethrough,
wherein the lifting device is configured to position the packaging with the first component over the mixing and conveying device such that a total height of the system is less than 230 cm.

2. The system as claimed in claim 1 , wherein the first component is a dry product or a dry mixture, and the second component is a liquid product or a liquid mixture.

3. The system as claimed in claim 2 , wherein the first component comprises cement and the second component comprises water such that mortar is obtained as the building material.

4. The system as claimed in claim 1 , wherein the lifting device comprises an inverted fork, and the suspension device is configured to be hung on a highest region of the fork.

5. The system as claimed in claim 1 , wherein the lifting device is a forklift truck or a pallet truck.

6. The system as claimed in claim 1 , wherein the cover is substantially cuboidal or cylindrical.

7. The system as claimed in claim 1 , wherein a ratio of a cover height to at least one of a cover width and a cover depth is between 0.6 and 1.0.

8. The system as claimed in claim 1 , wherein a cover height is between 50 and 100 cm, and at least one of a cover width and a cover depth is between 60 and 110 cm.

9. The system as claimed in claim 1 , wherein the cover has a lining.

10. The system as claimed in claim 9 , wherein at least one of (i) the lining comprises a plastic film, and (ii) the lining is at least partially adhesively bonded to the cover.
