Product Details
Sculpted U-Shaped Main Boom:
1. Our U-shaped arm boasts a masterfully engineered multi-section arc system, offering an impressive cross-sectional modulus and remarkable load-bearing capacity. This innovative design not only ensures stellar stability but also significantly reduces the crane's weight without compromising strength, perfectly aligning with the modern demands for lightweight solutions.
2. Effortless usability and robust adaptability define our U-shaped arm, seamlessly catering to diverse performance needs and working conditions. Its sleek and stylish appearance embodies cutting-edge manufacturing principles centered on safety, environmental consciousness, and unwavering reliability. This arm stands out as lighter, safer, more sophisticated, eco-friendlier, and immensely functional.
Versatile Rope Release Mechanisms:
We offer dual rope release methods: inner and outer rope out, tailored meticulously to customer specifications.
Prior to crane operation, diligently inspect the steel wire rope's clamp. Verify the clamp's secure fixation of the rope and ensure proper alignment within the groove. Replace the steel wire rope immediately if twisted, creased, excessively worn, severely corroded, showing over 10% wire breakage, a diameter reduction over 7%, or signs of overheating discoloration.
Precision Hydraulic Oil Cylinder:
The smooth extension and retraction of our on-board crane are primarily powered by the hydraulic oil cylinder's precision actions.
Choose between our advanced single or double cylinder oil cylinders to best suit your operational needs.
A meticulously designed balance valve regulates the telescopic rods, ensuring seamless boom extension and retraction sequences.
Our oil cylinder barrels undergo rigorous quenching and tempering processes, endowing them with exceptional tensile strength.
Enhanced with quenching, tempering, and a hard chromium outer coating, our piston rods exhibit superior rust prevention and wear resistance.
Our sealing components are crafted to meet the highest industry standards, perfectly compatible with the host machine's operating conditions.
Premium High-Quality Slewing Support:
Known as the 'joints of machines,' our rotary bearings are engineered for excellence.
For small tonnage truck-mounted cranes, we incorporate integrated slewing supports, while large tonnage counterparts benefit from sophisticated split slewing supports.
Experience limitless maneuverability with our crane's 360° infinite rotation capability.
Configurations for Rear Outrigger:
Choose from three rear outrigger configurations: fixed, single cavity, and double cavity, tailored to your specific requirements.
Our clients have the flexibility to select the rear leg that aligns best with their operational needs and preferences.
