Customer Challenge
Our customer, a leading offshore construction enterprise, needs to equip a newly-built engineering vessel with a high-performance offshore crane. The vessel has limited deck space, yet the operational requirements are extremely stringent: it must not only have a strong lifting capacity of 100 tons but also enable flexible and precise cargo hoisting and equipment handling on the crowded vessel deck and under complex sea conditions. The design and manufacturing of the crane must fully comply with offshore safety standards, and an ABS certificate, as well as a manufacturer's quality conformity certificate, must be provided.

Solution
In response to the customer's specific needs and the characteristics of the actual operating environment, we have designed, manufactured, and successfully delivered a 100-ton knuckle boom offshore crane with the model number YFMKBC-100.
This offshore crane is Specifically Designed for Space Constraints and High-Intensity Operations.
Its core advantages are as follows:
- Innovative Knuckle Boom Design: Unlike traditional straight boom cranes, the articulated boom of the knuckle boom offshore crane allows it to "bend" like a human arm. This feature enables it to be flexibly "folded" on narrow decks, occupying a smaller slewing space while easily avoiding obstacles-facilitating precise operations near the ship's side or through superstructures.
- Powerful Lifting Performance: While ensuring a compact structure, the YFMKBC-100 does not compromise on strength in the slightest. It delivers a maximum lifting capacity of up to 100 tons and is equipped with a sophisticated hydraulic control system, enabling smooth operations across the entire range-from heavy-load hoisting to precise positioning of light objects.
- ABS-Certified Safety Assurance: The offshore crane has successfully obtained full certification from the American Bureau of Shipping (ABS). This internationally recognized certification signifies that its design, materials, manufacturing processes, and performance all comply with the strictest international standards for marine engineering, providing crucial safety and reliability endorsement for the customer's offshore operations.

Outcomes and Value
Since its installation, this knuckle boom offshore crane has become an indispensable core piece of equipment in the customer's fleet. It perfectly resolves the conflict between deck space and lifting capacity, significantly improving the vessel's space utilization and operational efficiency. The operation team reported that the crane's flexibility and control precision have greatly reduced the time required for hoisting operations; even under rough sea conditions (with wind and waves), its stable performance ensures operational safety.
The customer stated:
--- "This knuckle boom offshore crane fully meets our expectations, and the ABS certification gives us great confidence when participating in international projects. It is a professional piece of equipment truly built to solve practical problems."
--- "From the pre-project communication to product delivery and subsequent technical support, the YFM team has demonstrated a high level of professionalism and responsibility. Cooperating with YFM has been a very pleasant experience."
Conclusion
The successful application of this 100-ton knuckle boom offshore crane and its acquisition of ABS certification once again demonstrate our professional capabilities in designing and manufacturing high-performance offshore lifting solutions. We are committed to providing customers with reliable products that not only have excellent specifications but also effectively address on-site challenges.
