Patent ID: 8251338

Claim:
Constant bearer for loads which are displaced, in particular for pipelines and the like, 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, wherein the compensation device displays a cam part coupled to the load-bearing part, in that the suspension system encompasses at least one spring that has a load side acting on a load point on the cam part to transmit force from the suspension system to the load-bearing part, wherein the cam part comprises at least one cam lever which is mounted in a swivelling way about a swivelling axis on the fastening part, and wherein a correction device is provided to correct deviations in the carrying force over the carrying travel resulting from a changed prestressing spring force, characterized in that the load point is supported at a distance to the swivelling axis on the cam lever in a guide the load point is moveable and fixable guided in, wherein the distance forms a power arm for transmitting the spring force on the load-bearing part and the orientation of the power arm relative to the load bearing part and its arm length are changed by moving the load point in the guide.
