XCMG 8ton hydraulic small truck crane QY8B.5 service truck crane for sale
More excellent performance
• The optimizing layout of the machine makes the stress of the main bearing carriers more reasonable, and the lifting performance is higher than the products with the same tonnage.
• Apply the mature jib technique which integrates plug-in boom head, embedded boom block, and special telescoping mechanism, which makes the jib more stable and reliable.
• Optimize the stress design. Adopt the box-type outriggers which have larger span, stronger rigidity, and better stability.
More reliable quality
• Adopt the classic K series jib telescoping technique, working safer and more reliable.
• Make the most complete safety device system in the industry, ensuring the lifting safer and more reliable.
• The comprehensively upgraded brake system adopts double circuit air pressure design. Multiple systems ensure the brake safety of the truck during travel.
• The intensity and rigidity of the rotary table and frame structure with high rigidity are completely coordinated.
• The perfect integration of the design and structure realizes the automation of welding, which is more reliable.
Easier to maintain
• The optimizing design of the pipeline traces makes the layout more scientific and reasonable, greatly reducing the dismantling and installing time of the pipelines and the maintenance expense.
• Completely upgrade the electrical system. Adopt anti-creep connector clips, greatly prolonging the service life of the parts.
• Adopt K series rope anti-disorder technique, improving the lifting efficiency, reducing the labor intensity, and prolonging the service life of the steel rope.
• The telescoping steel wire rope oriented and protective device avoids the steel wire rope out of the track and broken.
More energy-efficient and environmental friendly
• Adopt double industrial automation control engine, featuring strong power and energy efficiency.
• Under the economical mode, it can meet the engine power requirement of the normal lifting work. Under the high power mode, it can meet the requirement of the high challenge and high efficient lifting work.
• Adopt the advanced matching technique, which makes the design more scientific. It can reduce the consumption of the mechanism, prolong the service life of the machine, and has high residual value.

Company profile
XCMG is a construction machinery manufacturer with over 70 years of experience. Over the years, we have grown to become the world's most comprehensive construction machinery manufacturer and influential multinational company. In 2015, we rank No.1 in China and No. 5 in global heavy equipment industry.XCMG's construction machinery covers an astonishing range of equipment, including cranes, earth-moving machinery, road machinery, excavators, concrete machinery, mining machinery, piling machinery, lumber machinery, fire-fighting machinery, heavy trucks, sanitation machinery, agricultural machinery, and more. We have the world's most comprehensive product line, and offer customers complete solutions for construction equipment. Our other businesses include finance, leasing, and remanufacturing.
At present, the power of my company's straight-arm crane is entirely from the hydraulic oil pressure, that is, through the high-pressure hydraulic oil to promote the cylinder piston reciprocating motion, or drive the hydraulic motor rotation makes the hydraulic winch and rotary mechanism rotation.
So, how do high-pressure hydraulic oil get? Each truck crane is equipped with a hydraulic pump when the vehicle chassis is matched, and the engine provides power for it. The chemical energy of the fuel can be converted into the crankshaft of the engine to rotate the mechanical energy, and then the gearbox gear is rotated, and then the power is transmitted to the hydraulic pump through the power transmission of the gearbox. Therefore, the hydraulic pump can continuously pressurize the hydraulic oil For the high-pressure hydraulic oil, so as to provide power for the crane to achieve the lifting of the goods.
Competitive Advantage
My company's straight arm crane crane covers 1-25 tons 14 models 65 kinds of products, to meet a variety of conditions, with the longest arm of the largest tonnage crane mature manufacturing technology, scientific research and development process, advanced Research and development technology, and constantly have new products to market, to meet customer use.
My company's boom arm section with mature pentagonal, hexagonal and octagonal, the latest generation of products with U-shaped arc arm body weight reduction, arm width of a large deflection, stability and resistance to deformation Ability to improve, significantly enhance the lifting capacity.
The application of the sub-arm, sub-winch and vice-hook provides a basis for the rapid and large-scale operation of the crane light load and the high-altitude operation. The application of automatic hook technology saves time and effort when starting and ending crane operations, making it easy to operate easily.
