Rope release method:
Choose between two innovative rope configurations: inner rope out and outer rope out, both customizable to meet your specific requirements.
Prioritize safety with a meticulous inspection of the steel wire rope's clamp. Ensure the clamp's security, check the rope's alignment in the groove, and act swiftly to replace the rope when twisted, creased, worn, significantly corroded, or if it shows over 10% wire breakage, more than a 7% reduction in diameter, or discoloration from overheating.
Hydraulic Oil Cylinder:
The dynamic extension and bending capabilities of our on-board crane are driven by the powerful hydraulic oil cylinder.
Our range includes both single and double cylinder oil cylinders, catering to diverse operational needs.
Equipped with a balance valve, our system guarantees a seamless sequence in boom extension and contraction.
Crafted with precision, our oil cylinder barrels undergo quenching and tempering treatments, granting them exceptional tensile strength.
The piston rod, treated for quenching and tempering, is enhanced with a hard chromium coating, significantly boosting rust prevention and wear resistance.
Our sealing components adhere to the highest standards, perfectly suited for the rigorous conditions of host machine operations.
High Quality Slewing Support:
Renowned as the 'joints of machines,' our rotary bearings set the benchmark for performance.
For versatility, small tonnage truck-mounted cranes utilize integrated slewing supports, while large tonnage models benefit from split slewing supports.
Revolutionize your operations with our crane's capability for infinite 360° rotation, offering unparalleled maneuverability.
Rear outrigger :
Select from three distinct forms of rear outriggers: fixed, single cavity, and double cavity, each designed for specific operational advantages.
Tailor your selection with ease; customers can choose the rear leg that perfectly aligns with their operational needs.
