Patent ID: 8152126

Claim:
Constant bearer for moving loads, especially pipelines and similar, comprising a fastening part, a load-bearing part, and a spring system located between the fastening part and the load-bearing part for generating a constant bearing force, where the spring system displays a main spring assembly absorbing the load and a compensating device to compensate for changing spring forces of the main spring assembly on the load-bearing part, wherein the main spring assembly comprises main compression springs disposed opposite each other, wherein the compensating device displays at least one cam part, in that the cam part is coupled to the main spring assembly and the load-bearing part for load transmission from the main spring assembly to the load-bearing part, and in that, when the load-bearing part moves along a travel path, the load-bearing part and the cam part can move relative to each other on a non-linear path in such a way that complete compensation for the changing spring forces of the main spring assembly on the load-bearing part can be achieved, wherein the cam part includes at least one lever, designed as a cam lever and mounted on the fastening part in pivoting fashion, with two opposite side faces in its longitudinal extension, a first side face and a second side face, in that the load side of the main spring assembly is mounted on the first side face in pivoting fashion, and in that the second side face is designed as a concave cam side face, on which the load-bearing part rests and moves over the whole travel path of the load-bearing part, and is decreasingly deflected, over the whole travel path, away from an end of the load-bearing part for application of the load.
