Product Details
U-Shaped Main Boom:
1. The innovative U-shaped arm features an advanced multi-section arc design, significantly enhancing the cross-sectional modulus. This results in exceptional load-bearing capacity and stability, all while minimizing the crane's weight compared to traditional designs. This modern solution is perfectly aligned with the drive towards more lightweight machinery.
2. Designed for versatility, the U-shaped arm excels in diverse work environments, offering unmatched adaptability. Its stylish, contemporary appearance reflects our commitment to manufacturing principles of safety, eco-friendliness, and reliability. Enjoy the benefits of a lighter, safer, more sophisticated, and environmentally conscious product, without compromising on functionality.
Rope Release Method:
Our crane offers two rope release options: inner and outer, meticulously crafted to meet specific customer demands.
Prior to crane operation, ensure the steel wire rope clamp is inspected. Verify the clamp's security and that the rope rests correctly within its groove. Replace the rope if it shows signs of twisting, significant wear, corrosion, breaks exceeding 10%, a diameter reduction over 7%, or overheating discoloration.
Hydraulic Oil Cylinder:
The crane's impressive extension and bending capabilities stem from the precision-engineered oil cylinder.
Available in single and double cylinder configurations to cater to varied operational needs.
A balance valve strategically placed between telescopic rods ensures seamless, sequential boom movements.
The oil cylinder barrel's raw materials undergo rigorous quenching and tempering, ensuring superior tensile strength.
Post-quenching, the piston rod is fortified with a hard chromium coating, enhancing its rust and wear resistance.
Sealing components are crafted to meet the highest standards, perfectly matched to the host machine's operating conditions.
High-Quality Slewing Support:
Slewing bearings, pivotal machine joints, are engineered for durability and precision.
Choose from integrated slewing supports for smaller cranes, or split options for larger models, tailored to performance needs.
Our crane boasts an infinite 360° rotational capability, offering unparalleled maneuverability.
Rear Outrigger:
Select from three rear outrigger designs: fixed, single cavity, and double cavity, each offering unique advantages.
Tailor the crane to your specific requirements by choosing the ideal rear leg configuration.
