Product Details
U-Shaped Main Boom:
1. Embrace the future of lifting technology with our advanced U-shaped arm, featuring an innovative multi-section arc system. This design boasts a large cross-sectional modulus, ensuring superior strength and remarkable stability. It masterfully reduces the crane's weight without compromising its load-bearing capacity, perfectly aligning with the industry's push toward lightweight machinery.
2. The U-shaped arm not only delivers exceptional functionality but also showcases a sleek, contemporary look that embodies the principles of safety, environmental sustainability, and reliability. Lighter, safer, and more sophisticated, this arm is engineered to provide more environmentally friendly and versatile operations for diverse working environments.
Rope Release Method:
Our crane's rope release system provides two options: inner rope out and outer rope out, tailored to meet specific customer requirements.
Before operating the crane, a thorough inspection of the steel wire rope and its clamps is essential. Ensure that the rope clamp is securely attached and the rope sits properly in the groove. Replace the steel wire rope if it shows signs of twisting, creasing, excessive wear, severe corrosion, has more than 10% broken wires, a diameter reduction of over 7%, or discoloration from overheating.
Hydraulic Oil Cylinder:
The powerful extension and retraction of our onboard crane rely heavily on the precision-engineered hydraulic oil cylinder.
Choose between single or double cylinder configurations to meet your specific lifting requirements.
A sophisticated balance valve ensures that each boom extension and retraction occurs in a precise, sequential manner.
Our oil cylinder barrels undergo rigorous quenching and tempering, offering impressive tensile strength for demanding operations.
The piston rod is fortified through quenching and tempering, with a hard chrome coating on the outer surface to significantly enhance rust prevention and wear resistance.
Our sealing components meet the highest standards, perfectly suited for the host machine's operational demands.
High Quality Slewing Support:
Often referred to as the "joints of machines," rotary bearings are integral to our design.
For different applications, our cranes incorporate either integrated slewing supports for smaller tonnage or split slewing supports for larger tonnage, ensuring the best fit for your needs.
Experience limitless flexibility with our crane's ability to rotate a full 360°, offering unparalleled maneuverability.
Rear Outrigger:
Select from three rear outrigger forms: fixed, single cavity, and double cavity, each designed to stabilize the crane during operation.
Tailor your crane setup by selecting the rear leg that best suits your operational demands and preferences.
