Product Details
U-shaped Main Boom:
1. Our U-shaped main boom utilizes an optimized multi-section arc arm system, boasting a large cross-sectional modulus, delivering robust load-bearing capabilities. It ensures exceptional stability and significantly reduces the crane's weight without compromising its bearing capacity, aligning perfectly with modern lightweight demands.
2. The U-shaped arm is your robust partner, offering seamless adaptability to various performance and operational conditions. Showcasing a sleek and contemporary design, it epitomizes our commitment to safety, environmental friendliness, and reliability. This arm stands out as lighter, safer, more sophisticated, eco-conscious, and highly functional.
Rope Release Method:
Choose from two rope release methods: inner rope out and outer rope out, customized to meet specific customer preferences.
Prior to crane operation, a rigorous inspection of the steel wire rope's rope clamp is crucial. Ensure the clamp secures the rope firmly and rests within its groove. Should the wire show twisting, creases, wear, severe corrosion, a breakage exceeding 10%, a diameter reduction beyond 7%, or overheating-induced discoloration, replacement is mandated.
Hydraulic Oil Cylinder:
The dynamic extension and bending of our onboard crane are driven by the powerful hydraulic oil cylinder.
Options include single-cylinder and double-cylinder configurations to suit varied needs.
A balance valve positioned between telescopic rods ensures precise and orderly boom extension and contraction sequences.
The oil cylinder barrel undergoes quenching and tempering treatments, achieving remarkable tensile strength.
The piston rod features a quench-tempered base with a hard chromium-coated outer circle, enhancing rust prevention and wear resistance.
Our sealing components adhere to stringent standards tailored for optimal compatibility with the host machine's operating conditions.
High-Quality Slewing Support:
Often referred to as the "joints of machines," our rotary bearings are indispensable.
For small tonnage truck-mounted cranes, integrated slewing supports are used, while large tonnage cranes opt for split slewing supports.
Experience limitless 360° rotation with our crane's innovative design.
Rear Outrigger:
Available in three configurations: fixed, single cavity, and double cavity.
Select the rear leg that best aligns with your operational needs, customized for your satisfaction.
