Abstract
A suspension system for supporting pipes under generally constant tension comprises a main spring system including a main spring located between a suspension portion and a load-bearing portion for applying spring-biasing forces to the suspension portion. An additional spring system includes an additional spring which compensates for variations in the spring-biasing forces of the main spring through associated cam and cam followers. An auxiliary hydraulically operated mechanism is provided for applying a supplementary predetermined biasing force to increase or decrease the biasing forces of the main springs in response to detected value/parameters.
Claims20
A suspension system for supporting loads, such as pipes, under generally constant tension comprising a main spring system including a main spring constructed and arranged between a suspension portion and a load-bearing portion for applying spring-biasing forces to the suspension portion in a predetermined direction, an additional spring system including an additional spring constructed and arranged to compensate for variations in the spring-biasing forces of the main spring, cam and cam follower means between said main and additional springs and responsive to main spring-loading to selectively increase or decrease the biasing forces of the additional spring, and hydraulically operated auxiliary means for applying a supplementary predetermined biasing force to selectively increase or decrease the biasing forces of said main spring in said predetermined direction and a direction opposite thereto.
