Used Xcmg Hb58v Concrete Pump Truck
Product Introduction
As a new generation of products integrating German Schwing’s technology, XCMG’s V7 series of concrete machinery is leading the industry with its excellent quality of “safety, reliability, environmental protection and leadership”. Among them, V7 series concrete pump trucks innovatively adopt lightweight machine matching technology, high-efficiency pumping technology, energy-saving and environmental protection technology, bionic structural design and other core technologies, making the products safer, more reliable and more efficient. Especially since the two star products, 4-bridge 58m pump truck and 4-bridge 62m pump truck, were launched in the market, they have been well received and have been in short supply for many times. 4-bridge 60m products have a market share of 48%, and their market performance and customer acceptance have far exceeded that of other competitors in the industry.
HB58V concrete pump truck is the world’s longest boom pump truck with four-axle curved outriggers independently developed by XCMG, leading the domestic industry with its excellent quality of “safety, reliability, environmental protection, and leadership”, and the performance of the whole machine has reached the international advanced level. A number of technologies of this product are the first in the industry, with a total of 9 patent applications (including 1 invention patent), 9 authorizations (including 1 invention patent), and 1 software copyright.
Appraised by the China Machinery Industry Federation in March 2019, the overall technology of the product reaches the international advanced level, and the full hydraulic reversing technology and pumping integral casting hydraulic valve technology applied in this vehicle reach the international leading level.
Product Features
HB58V adopts curved outriggers, realizing a revolutionary breakthrough in outrigger layout. One-stage telescopic curved outriggers can realize the span of two-stage telescopic X outriggers, and the overall rigidity of the vehicle is large, and the whole vehicle has good working stability and high safety, and compared with the same-meter X outrigger products, the deformation of the outriggers is smaller than 50%, and the amount of leg lifting is smaller than 50%. As the rigidity of the outrigger is improved, the span of the outrigger of the same meter number is reduced by 10%, which is easier to be close to the site construction and has strong adaptability to the site. The telescopic mechanism is simple, with fewer failure points and high reliability.
Aiming at the problem of fatigue cracking of traditional boom and conveying pipe, the company innovatively adopts pipeline optimization arrangement technology and develops a new type of boom support device, and designs the original welded limiting bracket into an assembly form, which solves the problem of fatigue cracking of traditional boom and improves the service life of the boom.
Adopting skirt valve pumping system, the front and rear ends are not subject to bias load moment, which is easy to maintain, with double sealing guarantee, the suction efficiency is over 95%, while the life span of the shaft end is longer. Pumping main valve adopts monolithic structure, full casting oil pipeline instead of machining oil pipeline, canceling transition valve block, reducing the number of oil pipeline by 80%, and reducing the loss along the pipeline by 60%. The breakthrough of full hydraulic reversing technology realizes stable and reliable reversing, reduces reversing impact, and the reversing time is less than 200ms, which is 50% lower than the existing level in the industry, and the pumping efficiency is increased by 10%.
