PY140-36 Kyokuto Concrete Boom Pump

The PY140-36 is a piston-type truck-mounted concrete boom pump in the 36 m long-reach class, aimed at large-scale building and civil sites where high placement volumes need to be delivered over an extended boom without repositioning the vehicle. It is a direct model change from Kyokuto's earlier PY125-36A, retaining the same reach class while improving pumping output and unit efficiency. The pump moves to electric control of the main hydraulic pump, lifting maximum output to 138 m³/hr in 9B specification — around 11% higher than the previous model — with output improved through the 60–80 m³/hr working range. It also carries Kyokuto's IoT-based K-DaSS monitoring system for recording vehicle operating data, the KAVS boom vibration-damping system, and a water tank capacity increased to 490 litres for washdown after placement.
