  • Patent number: 8251338
    Abstract: A constant bearer having a fastening part, a load-bearing part and a spring system which is arranged between the fastening part and the load-bearing part for generating a carrying force which remains constant over a carrying travel of the load-bearing part with respect to the fastening part, where the spring system has a suspension system for absorbing the load, a compensation device for compensating for changing spring forces of the suspension system over the carrying travel, and a prestressing device for setting a prestressing force of the suspension system.

  • Patent number: 7861983
    Abstract: The invention relates to a cold-insulated fixed-point pipe support for a low-temperature pipeline which includes an insulating system arranged between an outer shell and a supportable low-temperature pipeline having solid thermal insulating material which thermally insulates the pipeline from the low-temperature environment. A rotation-preventing and displacement-preventing device prevents rotation and displacement of the thermal insulating material with respect to the pipeline and an outer shell. A fixed-point pipe support is adapted to be fitted and removed in a substantially radial direction over the pipeline, and has at least one division with respect to shape with a division plane thereof extending perpendicular to a cross-sectional plane, and having a connecting device for releasable connecting and fixing shaped parts formed by the division.

  • Patent number: 7320448
    Abstract: The invention relates to a pipe clip 1 for mounting pipes and the like, comprising a suspendable upper part 2 and a U-shaped lower part 3, the ends of which can be connected to upper part 2 by means of fastening elements and in which a pipe is mounted. Lower part 3 is manufactured in one piece by deformation of a creep-resistant flat steel bar or strip of sheet metal, where lower part 3 displays a cross-section with at least one wider, plane lateral surface 12, which is located on the inside and on which the pipe to be mounted rests, and upper part 2 displays a holding-down device 4 for holding down the pipe mounted in lower part 3.
