Product Details
U shaped main boom :
1. Our innovative U-shaped arm features an expertly optimized multi-section arc arm system. This design boasts a large cross-sectional modulus and exceptional load-bearing capacity, ensuring outstanding stability. This system significantly reduces crane weight while maintaining the same bearing capacity, perfectly aligning with the growing demand for lightweight yet robust machinery.
2. The U-shaped arm is intuitively designed for ease of use and showcases remarkable adaptability across diverse performance scenarios and operational conditions. The arm's modern, elegant appearance embodies the ethos of safety, environmental stewardship, and uncompromising reliability. Its outstanding attributes include being lighter, safer, and more premium, while also delivering eco-friendly and multifunctional performance.
Rope release method:
Our crane offers dual methods for rope deployment: inner rope out and outer rope out, tailored precisely to customer specifications for optimal flexibility.
Before crane operation, a meticulous inspection of the steel wire rope's clamp is essential. Confirm that the rope clamp securing the steel wire rope is firmly in place, and ensure the rope is properly seated in the groove. Should the steel wire rope exhibit twisting, creasing, severe wear, corrosion, a breakage exceeding 10%, a diameter reduction over 7%, or discoloration from overheating, immediate replacement is warranted for operational safety.
Hydraulic Oil Cylinder:
The crane's extension and bending motions are powered primarily through the action of the hydraulic oil cylinder.
Our system includes options for both single and double cylinder oil cylinders, offering versatility to meet varied needs.
A strategically placed balance valve between the telescopic rods ensures seamless and orderly boom extension and contraction.
The oil cylinder barrel's raw materials undergo rigorous quenching and tempering treatments, imparting impressive tensile strength essential for demanding operations.
The piston rod benefits from quenching and tempering, further enhanced by a hard chromium coating on the outer circle, significantly boosting rust prevention and wear resistance.
Sealing components adhere to the highest standards, specifically designed to withstand the operational conditions faced by the host machine, ensuring peak performance.
High Quality Slewing Support:
Rotary bearings, often referred to as 'machine joints', are integral to our crane's design for reliable rotation.
Our small tonnage truck-mounted cranes utilize integrated slewing supports, while large tonnage models are equipped with split slewing supports, illustrating our commitment to tailored solutions.
Experience limitless flexibility with our crane's ability to rotate 360° infinitely, providing unmatched operational agility.
Rear outrigger :
Our rear outrigger options include fixed, single cavity, and double cavity forms to cater to diverse operational demands.
Customers are empowered to select the rear leg configuration that best aligns with their specific needs, ensuring optimal functionality and performance.
