Multiquip 515812 Throttle Control Plate

The Multiquip 515812 Throttle Control Plate is a genuine OEM component designed for Mayco hydraulic-driven concrete pump models LS400, LS40D, LS40TD, LS500, and LS50TD. As a direct OEM replacement, this plate is manufactured to the exact specifications required by the original equipment, ensuring it integrates correctly into the throttle control system without modification. DHS Equipment sources this part directly through authorized Multiquip channels, so you can order with confidence knowing you are receiving the correct component for your machine. Verify your model code against the fitment list before ordering to confirm compatibility.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design specifications for the throttle control system, ensuring correct geometry and material grade for consistent throttle response.
• Direct Bolt-In Replacement — Engineered to match the original mounting configuration on Mayco LS-series concrete pumps, slotting into place without rework or adaptation.
• Broad LS-Series Fitment — Compatible with LS400, LS40D, LS40TD, LS500, and LS50TD Mayco hydraulic concrete pump models.
• Maintains Precise Throttle Actuation — A worn or damaged throttle control plate can cause erratic engine response and inconsistent pump output; this replacement restores proper throttle travel and control feel.
• Correct Part for Hydraulic Pump Applications — Sized and rated for the demands of hydraulic-driven concrete pump operation, where stable throttle control directly affects pumping pressure and material delivery.

The throttle control plate is a structural component within the engine throttle linkage assembly of the concrete pump. It acts as the mechanical interface that translates operator input into controlled throttle movement, governing engine speed and, in turn, hydraulic pump output. When the plate becomes worn, bent, or cracked, throttle response becomes unpredictable, leading to inconsistent pumping pressure and potential difficulty controlling concrete flow at the point of placement.
