  • Tank container with mounting means
    Patent number: 4416384
    Abstract: A tank container comprising a framework (1-4) and a tank (7) disposed therein.The tank (7) is secured in the framework (1-4) by means of members (8, 11) transmitting tensile forces in the axial and radial directions of the tank wall so that no bending moment is exerted on the tank wall. These members are preferably radial suspension plates (8) between the ends of the tank and the corners of the end frames and axial fastening plates (11) between the cylindrical portion of the tank and the corners of the end frames.

  • Container truck for lifting and carrying away a container
    Patent number: 4390314
    Abstract: A container truck for lifting up a container (13) into position on the truck (1) for subsequent transport. In order to achieve a simple and cheap construction without a counterweight, an end portion (15) of the truck (1) in contact with the container (13) can be brought to bear against the support for the truck during the lifting of the load into a transport position on the truck, in that there are hydraulic cylinders (16) between the wheel axle and the truck.

  • Insulated tank container
    Patent number: 4376494
    Abstract: The invention relates to an insulated tank container. In order to obtain a particularly light and cheap construction, the tank container consists of a thin inner shell (4) and outside this semi-hard or hard insulation (6, 8, 10, 11) which has the capacity to take up and transfer stresses in various directions and is firmly glued to the inner shell. An outer shell (5, 7, 9) with a framework (1) may be disposed outside the insulation. As an alternative, the insulation may be introduced, foamed and hardened in situ between preformed shells.

  • Method of emptying a powder or like material out of a container
    Patent number: 4363574
    Abstract: Method of emptying a powder or like material out of a container.The powder (9) is conveyed out of the container (1) from its free upper surface by means of a stream of carrier air in a carrier-air pipe (6; 10; 12) provided with openings for the powder. The emptying is facilitated by means of a stream of secondary air from a secondary-air pipe (7; 11; 13). The container is rotated so that the fixed carrier-air pipe may come into the vicinity of the surface of the powder.
