Abstract:
1. Constant bearer for moving loads, especially pipelines and similar, comprising a fastening part including a housing, a load-bearing part, and a spring system located between the fastening part and the load-bearing part for generating a constant bearing force, wherein the spring system includes a main spring assembly absorbing the load and an auxiliary spring assembly to compensate for changing compressive forces of the main spring assembly, and wherein the main spring assembly includes a main compression spring assembly disposed roughly perpendicularly to the bearing force, wherein the main compression spring assembly comprises main compression springs disposed opposite each other, wherein at least one cam part facing towards the main compression spring assembly is provided on the load-bearing part guided in sliding fashion over a travel path in the bearing force direction, and in that a load side of the main compression spring assembly is supported on the cam part of the load-bearing part, wherein the auxiliary spring assembly displays auxiliary compression spring assemblies that run parallel to the main compression spring assembly and act on the load-bearing part via auxiliary cam parts, where the auxiliary cam parts are located on independent pivoted levers.
