Abstract
A positioning mechanism for lowering a suction manifold from an operational position with respect to pump fluid end to a transit and service position includes a linkage base plate configured to be fixedly coupled with a vehicle trailer, a linkage arm pivotally coupled with the linkage base plate and the suction manifold, a primary damper pivotally coupled with the linkage base plate and the linkage arm, a secondary damper pivotally coupled with the linkage base plate and the suction manifold, and a mechanical stop removably coupled with the secondary damper and configured to maintain the secondary damper at a fixed length while the mechanical stop is coupled with the secondary damper. The positioning mechanism permits the suction manifold to fall under the force of gravity when the suction manifold is detached from the pump fluid end, the primary damper is configured to slow the fall of the suction manifold under the force of gravity, and removal of the mechanical stop from the secondary damper permits the secondary damper to shorten from the fixed length to a shorter length under the force of gravity.
