The Multiquip EM70401 Shuttle Cylinder ST80 is a genuine OEM Shuttle Cylinder designed for the ST80 swing tube concrete pump. As a direct OEM replacement, this cylinder is manufactured to the same specifications as the original component, ensuring proper fit and integration with the ST80 hydraulic system. Sourced directly through authorized channels, the part is the correct part for operators and service technicians maintaining ST80 series equipment.
Key Features
- Genuine OEM Hydraulic Integrity — Manufactured to original bore tolerances and seal-seat dimensions, ensuring correct pressure retention and stroke consistency specific to the ST80 shuttle circuit.
- Direct-Fit for ST80 Concrete Pumps — Engineered to bolt directly into the ST80 swing tube pump assembly with no reworking of mounting points or hydraulic fittings required.
- ST80 Series Compatibility — Confirmed fitment for the Multiquip ST80 concrete pump, giving service technicians confidence when sourcing replacement hydraulic components.
- Sustains Pumping Output — A properly functioning shuttle cylinder maintains the timed, reciprocating action of the swing tube mechanism; a worn or leaking cylinder causes erratic pumping cycles and loss of output pressure.
- Critical Hydraulic Component — As part of the pump's hydraulic actuation circuit, correct cylinder operation is essential to safe, controlled swing tube movement and preventing uncontrolled hydraulic pressure release during operation.
The shuttle cylinder is the hydraulic actuator that drives the swing tube back and forth inside the ST80 concrete pump's hopper, directing concrete flow alternately into each pumping cylinder. It receives pressurized hydraulic fluid on command from the pump's control circuit, converting that pressure into linear motion to reposition the swing tube at the correct point in the pumping cycle. When this cylinder develops internal leakage, scoring, or seal failure, the swing tube loses precise timing, resulting in lost prime, reduced output, and potential damage to surrounding hopper components.
