Product Details
U Shaped Main Boom:
1. Experience the marvel of engineering with our U-shaped arm, enhanced by a sophisticated, multi-section arc arm system. This design boasts a large cross-sectional modulus, offering robustness and impressive stability. It drastically cuts down the crane's weight while maintaining exceptional load-bearing capacity, perfectly aligning with modern lightweight requirements.
2. The U-shaped arm is a paragon of usability, demonstrating remarkable adaptability across various performance parameters and working conditions. Its sleek and stylish design reflects our core values of safety, environmental care, and reliability. Enjoy a crane that's not just lighter and safer, but also more luxurious, eco-conscious, and functionally superior.
Rope Release Method:
Customize your crane experience with two available rope-out methods: inner rope out and outer rope out. Tailored precisely to meet customer specifications, these methods ensure optimal performance.
Before harnessing the power of the crane, conduct a meticulous inspection of the steel wire rope's clamp. Ensure the rope clamp is firmly secured and positioned correctly in the groove. Replace the steel wire rope if it shows signs of twisting, folding, wear, severe corrosion, if over 10% of the wires are broken, the diameter reduces by more than 7%, or discoloration occurs due to overheating.
Hydraulic Oil Cylinder:
Witness the dynamic extension and bending of our onboard crane, powered primarily by the high-performance oil cylinder.
Options include sophisticated single and double cylinder oil cylinders to suit diverse operational needs.
A meticulously engineered balance valve between telescopic rods ensures seamless sequencing of boom extension and contraction, enhancing operational efficiency.
Each oil cylinder barrel is crafted from raw materials subjected to rigorous quenching and tempering, providing unmatched tensile strength.
The piston rod's core integrity is fortified with quenching and tempering, and its outer surface is coated with hard chromium for superior rust prevention and wear resistance.
Our sealing components stand out with high standards, tailor-made to withstand the demanding conditions of the host machine.
High Quality Slewing Support:
Rotary bearings, known as the "joints of machines," are integral to our crane's superior performance.
Our cranes offer versatility with integrated slewing supports for small tonnage trucks and split slewing supports for larger models.
Experience limitless possibilities with our crane's ability to rotate 360° infinitely, delivering unparalleled maneuverability.
Rear Outrigger:
Choose from three expertly designed forms of rear outrigger: fixed, single cavity, and double cavity, to best suit your operational needs.
Tailor your crane setup with the perfect rear leg option, selected to match your specific requirements.
