What is a disadvantage of using trailer pumps for SOG placements?

Explanation:
Trailer-mounted pumps in slabs-on-grade work require moving the pipeline as the pour advances. The heavy pipe sections must be disconnected, lifted, moved forward, and reconnected, which introduces downtime and extra labor that slow down the placement. This time loss is the most noticeable drawback for SOG pours. Maintenance, reach, and noise can matter in some setups, but they’re not the primary disadvantage tied to SOG placements with trailer pumps.
