Concrete pump truck

1. Concrete Pump Truck Features and Benefits
Concrete Pump Truck Introduction:
The NF Boom-type Concrete Pump Truck (Truck-mounted Concrete Pump with Foldable Booms)
is developed by NF on the basis of drawing on advanced domestic and foreign experience and
using advanced modern computer simulation techniques to systematically analyze the effect of
changes in various parameters like stress, displacement and natural frequency on the boom’s
fatigue life. Meantime, NF optimized the design of the hydraulic system, adopted the latest free
fluid technique and greatly lessened the impact of pumping commutation on the distributing
boom. In the boom structure optimization and the hydraulic system design, NF has obtained many
patents. The consummate control of product quality, perfect techniques of product manufacturing
and strict procedures of quality inspection make the NF Pump Truck a leading product in China
and an advanced product in the world. All the steel plates for the boom system are high-strength
cold rolling steel plates made by the Swedish company SSAB. The yield strength of the plates
exceeds 900Mpa, which ensures that the boom system has high strength and light weight. The
boom system’s distributing pipe, landing legs, oil tank and so on have all received 100% stressremoving treatment after welding. Every welding seam has passed the 100% undamage and crack
detection or X-ray radial check to avoid any tiny defects and to make the machine more enduring.
