An unplanned pump downtime is never just a technical problem: it is a planning problem. Knowing which spare parts to keep in stock, and why, makes the difference between a repair that takes a few hours and a jobsite that stands idle for days.
The spare parts for truck-mounted concrete pumps that have the greatest impact on jobsite continuity are those for the pumping unit and the pipelines, the components most exposed to concrete flowing under pressure.
Having them on hand before they fail turns a breakdown into a scheduled replacement, instead of a wait that brings the pour to a halt.
The right stock level depends on how intensively the machine is used and on the type of concrete pumped. With frequent pours, wear plates and pumping pistons wear out faster than with occasional use, and the parts list should be tailored accordingly.
