ABSTRACT:
The invention relates to a 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.With the objective of more easily transmitting the forces of the spring assembly and enabling improved compensation for the changing forces of the main spring assembly, two basic embodiments are proposed as a solution, where, in the first embodiment, an auxiliary spring assembly, as part of the compensating device, and the main spring assembly are located roughly perpendicularly to the bearing force, at least one cam part facing the main spring assembly is provided on the load-bearing part guided in sliding fashion over a travel path in the bearing force direction, and a load side of the main spring assembly is supported on the cam part of the load-bearing part. In the second embodiment, the auxiliary spring assembly is dispensed with and compensation for changing spring forces over a spring excursion is achieved via a cam part13with cam lever.
