2023 Used SANY SYM5552THB 710S 71M Concrete Pump Truck Custom Chassis

2023 Model Sany Custom Chassis 71-meter Concrete Pump Truck

I. Product Positioning
The 2023 Sany S-series five-axle custom dedicated chassis 71-meter flagship pump truck of the S series, with the entire vehicle's upper and lower assemblies independently developed, a compliant self-weight of 55 tons, solves the problem of excessive weight for long boom pump trucks that are restricted by traffic regulations, and is mainly targeted at super high-rise construction, large-scale infrastructure, and overseas projects. Its cost performance and practicality far exceed the imported chassis of the same level.

II. Chassis and Power (Core Highlights of Custom Chassis)

Using Sany's exclusive five-axle pump truck chassis, the heavy-duty frame optimizes the center of gravity, making the site passability stronger; equipped with Sany Daiozatsu D13 engine, 530 horsepower, Euro VI emission standards, economical and fuel-efficient. The vehicle size is 16090×2550×4000mm, the total mass is 55000kg, compliant nationwide passage and registration without worries. The entire series is electrically controlled independently developed and interconnected, intelligent operation and fault self-checking are more convenient, and the maintenance parts cost is more than 30% lower than that of imported chassis.

III. Boom and Conveying Parameters (Six-section Boom)

Maximum vertical conveying height 70.2m (nominal 71m), maximum horizontal conveying distance 63.5m, maximum lowering depth 50.3m; supports 360° full rotation, full flat operation, minimum extension height only 16.9m, suitable for basements, pits, etc., low and narrow working conditions. Equipped with lightweight X-type three-extension legs, smaller footprint, stable support, no-armature vibration, less vibration and higher precision in high-rise pumping.

IV. Pumping Performance

Dual-mode adjustable: Low-pressure high-flow 180m³/h (8.3MPa), suitable for large-area floor pouring; High-pressure high-head 125m³/h (13MPa), suitable for super high-rise, long-distance high-grade concrete transportation. Equipped with large-capacity anti-blockage material bucket, thick-walled wear-resistant conveying pipeline, low blockage rate, high construction efficiency, dual water tank configuration, efficient and convenient cleaning operations.

V. Core Advantages and Application Scenarios
