Product Details
U Shaped Main Boom:
1. Our expertly crafted U-shaped arm features an optimized multi-section arc arm system. This design boasts a large cross-sectional modulus, offering exceptional bearing capacity and stability. By significantly reducing the crane's weight while maintaining its robust lifting power, our U-shaped arm meets the modern demands for lightweight machinery.
2. The sophisticated U-shaped arm is engineered for ease of use and adaptability, excelling in comprehensive performance across diverse working conditions. Its sleek and innovative design not only embodies safety, environmental friendliness, and reliability but also enhances its appeal as a lighter, safer, more premium, eco-friendly, and highly functional component.
Rope Release Method:
Our crane offers two rope release options: inner rope out and outer rope out, both customizable to meet specific customer requirements.
Prior to crane operation, it is paramount to inspect the steel wire rope clamp. Ensure the rope clamp is securely fastened, and the steel wire rope is properly seated in the groove. If the rope exhibits twisting, creasing, wear, severe corrosion, over 10% wire breakage, a diameter reduction exceeding 7%, or discoloration from overheating, replacement is essential.
Hydraulic Oil Cylinder:
The dynamic extension and retraction of the on-board crane are primarily driven by the sophisticated action of the oil cylinder.
Our hydraulic system offers both single cylinder and double cylinder configurations to suit varied operational needs.
A balance valve is strategically positioned between the telescopic rods, ensuring seamless and precise boom extension and contraction sequences.
The oil cylinder barrel is crafted from materials that undergo rigorous quenching and tempering, resulting in exceptional tensile strength.
The piston rod undergoes quenching and tempering, with its outer surface coated in hard chromium, significantly enhancing rust prevention and wear resistance.
High-standard sealing components are employed, expertly designed to withstand the rigorous operating conditions of the host machine.
High Quality Slewing Support:
Rotary bearings, aptly known as 'joints of machines,' are integral to crane functionality.
Our cranes utilize integrated slewing supports for small tonnage models, and split slewing supports for large tonnage cranes, ensuring optimal performance.
Experience the freedom of 360° infinite rotation with our advanced crane systems.
Rear Outrigger:
The rear outrigger is available in three configurations: fixed, single cavity, and double cavity, catering to diverse operational needs.
Customers have the flexibility to select the most suitable rear leg configuration according to their specific requirements.
