Truck-mounted Concrete Pump belonging high efficient concrete delivery equipment and high-tech products for running, pumping and placing the concrete. Reasonable structure, large carry capacity, stable working performance with it's narrow swing, the imported rotary bearing can widely afford tip-over while operating enhance it's safety performance. SSAB steel together use specialized welding process and heat treatment more improves the useful life.<o:p>
New RZ-shaped boom with compact structure, widely increase operate range. Some imported and OEM component parts as Germany "Rexroth" hydrualic pump, Germany "Harvey" boom mutiple valve, Germany "NBB" wireless remote control etc, can greatly help to ensure the equipment with high reliability and durability. Open loop hydraulic control, full-hydraulic directional provides sufficient operating hours in such mal-conditions. Heat dissipation with efficient cooling system. Capable lubrication system, widely improves the stability while "S" valve moving. Simple operation.<o:p>
Components:<o:p>
Up-loading System: Boom system, Rotary table, Slewing mechanism, Fixed turret, Landing leg. Main function: Complete the concrete delivery and placing which support the vehicle to ensure its stability.<o:p>
Pumping system: Support the boom section and achieve more stable movement.<o:p>
Rotary Table: Allowable turnable rotation 365°<o:p>
Outrigger: One-side support enables meet more mutiple working conditions, simple and flexible.<o:p>
Competitive Advantage:<o:p>
Large pumping displacement upto 120m³/h, stepless adjustment, low reversing frequency, small impact.<o:p>
Automatic retraction of concrete piston makes it easier to check or replace the piston, greatly extend sevice life of wearing parts.<o:p>
Intelligent reversing buffer control technology, which use computer monitoring the main oil cylinder motion process that to realize buffer and reversing, can sharply reduce the impact, with less than 10% concrete impulsive force.<o:p>
Computer simulation assisted design, intelligent boom damping technology, reduce 50% vibration at pipe tail end.<o:p>
Automatic switch-over between high and low pressure improves pumping applicability, non-leakage and pollution, greener environment. Release pipe block concerning pefectly.<o:p>
