Product Details
Revolutionary U-Shaped Main Boom:
1. Introducing an impeccably engineered U-shaped arm, crafted with an optimized multi-section arc system. This design marvel boasts a larger cross-sectional modulus, ensuring robust bearing strength, exceptional stability, and a significant reduction in crane weight without compromising capacity. It flawlessly satisfies the modern industry's demand for lightweight construction.
2. The versatile U-shaped arm is engineered for user-friendliness and adaptable to diverse performance and operational conditions. Its captivating and contemporary design perfectly embodies safety, environmental consciousness, and reliability. Boasting attributes such as reduced weight, enhanced safety, premium quality, and superior environmental friendliness, it elevates functionality to new heights.
Innovative Rope Release Methods:
Experience unparalleled flexibility with two rope release mechanisms: inner rope out and outer rope out, meticulously crafted to align with specific customer requirements.
Prior to crane operation, a comprehensive inspection of the steel wire rope clamp is imperative. Ensure that the clamp securely fastens the steel wire rope and that it rests properly in the groove. If defects such as twisting, creasing, wear, severe corrosion, breakage exceeding 10%, diameter reduction beyond 7%, or overheating discoloration are detected, immediate replacement is essential.
Precision Hydraulic Oil Cylinder:
The seamless extension and retraction of the onboard crane are orchestrated by the powerful hydraulic oil cylinder.
Available in both single and double cylinder configurations to meet diverse needs.
A balanced valve ensures harmonious coordination in the sequential extension and contraction of telescopic rods.
Crafted with impeccable strength, the cylinder barrel's raw materials undergo rigorous quenching and tempering treatments for unparalleled tensile resilience.
The piston rod, also tempered and quenched, features a hard chromium coating on its outer circumference to enhance rust resistance and durability against wear.
Integrating high-standard sealing components tailored to endure the host machine's operational environment.
Premium Quality Slewing Support: Unmatched Performance
Rotary bearings, often revered as the 'joints of machines,' ensure flawless motion.
For small tonnage truck-mounted cranes, integrated slewing supports are employed, whereas large tonnage cranes benefit from split slewing supports.
Experience the power of 360° infinite rotation with our state-of-the-art crane.
Sophisticated Rear Outrigger Options:
Choose from three meticulously engineered rear outrigger forms: fixed, single cavity, and double cavity, each tailored to specific operational needs.
Empower your operations by selecting the most suitable rear leg option to meet your unique demands.
