2 Ton Knuckle Folded Boom Crane for Truck Hydraulic Lifting Crane Machine

2 ton knuckle folded boom crane for truck hydraulic lifting crane machine

Xuzhou Haoyi Construction Machinery Technology Co.,ltd, was established in 2010 and is located at No.16 Changxing Road,
Xuzhou High-tech Development Zone. It mainly produces truck-mounted cranes, hydraulic cranes,aerial work vehicles,
and other customized mechanical products. HaoYi has developed series of control system for truck mounted crane, aerial
lift fire vehicle, aerial work platform truck, rescue crane, high pressure aerial water jet fire vehicle, marine crane and other
products. Providing a variety of solutions to our valued customers. All above products have been widely applied in logistic,
fire fight equipment, railway track, petrochemical industry, engineering machinery, ship building, municipal public works,
park maintenance and other fields.
A. Materials:
Structural parts and hinge shafts: Our structural parts are all made of high-strength plates, such as key stress-bearing parts, are made of 70KG/80KG, or even 90kg high-strength steel plates (HG60, BS900), and the hinge shafts of key parts are all made of high-strength steel plates. 40Cr, or 42CrMo tempered and quenched. Advantages: high strength, strong bearing capacity, longer service life:
Oil red: Our hydraulic cylinders all adopt domestically well-combined seals, and we use main road seals, the outermost layer is a dust-proof ring, the inside is a support pad, and then a seal ring, and the product is guaranteed through multiple seals. Quality, advantages: long service life, not easy to aging, very low oil leakage rate
Pipeline: Parker standard high-pressure pipe is used. The joint adopts a 24° cone, ferrule and screw fit, not a commonly used O-ring. After the ferrule nut is installed, there will never be oil leakage, and the O-ring The ring is easy to age, advantages: stronger high pressure resistance and more durable;
Operation and safety valves: all adopt domestic famous brands, the valve cores are all imported, and the valve blocks are all domestically produced. Advantages: both quality and price, low oil leakage rate.
Oil pump: Hefei Saiyuan gear pump used below 6.3 tons, plunger pump from Qidong High Pressure Oil Pump Factory for folding arm and above 8 tons. Advantages: large speed range, reliable operation, long service life and convenient maintenance.
Slewing mechanism: powerful slewing, capable of 360° continuous rotation, advantages: easy operation, long life:
Hydraulic lifting mechanism: hydraulic winch, powerful hoisting, low noise, safe and reliable, fast lifting speed, advantages: long life, high efficiency:
Steel wire rope: multi-strand thin wire anti-rotation steel wire rope, advantages: high strength, good flexibility, no winding, high safety, safe and durable:
B. Process:
Automatic boom welding, good workmanship, good weld quality, good weld shape, less weld joints, no false welding, false welding, much better than manual welding, no pores, trachoma, cracks, unfused and other defects . Advantages: beautiful appearance, good weld quality.
Longer boom life:
The high-strength plate is pre-treated before welding to reduce welding stress, reduce post-weld deformation, and ensure the overall straightness of the long boom.
Polygonal boom: below 6 and 3 tons are pentagonal, and above 8 tons are similar to U-shaped booms: Advantages: good bending and torsion resistance, large bearing capacity, reducing self-weight and increasing boom strength:
The advantages of the polygonal turntable column: good bending and torsion resistance, large bearing capacity, reducing self-weight and increasing structural strength:
Sandblasting and shot blasting treatment after welding, benefits: rust removal (knock off the oxide skin on the surface), eliminate welding stress, form pitting on the surface (0.1-0.2mm dents), and improve the adhesion of the paint surface.
