In recent years, many bridges, docks, and underwater infrastructure built in the mid-20th century across the U.S. have entered demolition or renovation cycles. Unlike new projects, these old structures are often located in densely populated or ecologically sensitive areas, where traditional blasting and mechanical breaking methods face increasing restrictions. In this context, diamond rope saw—with its high cutting accuracy, low vibration, and underwater operation capability—has become a key tool for U.S. demolition contractors. Whether cutting concrete piles or using a diamond wire saw for stone in stone processing applications, this equipment shows good adaptability.

Technical Features of YG Diamond Rope Saw
YG’s diamond rope saw has several practical technical features.
First, cutting efficiency is fairly stable—under normal concrete conditions, it cuts about 8 square meters per hour, and 1 meter of wire cuts about 2.5–3 square meters; consumption increases when rebar is dense.
Second, the equipment supports underwater operation, meeting U.S. customers’ common needs for underwater cutting.
Third, the fully hydraulic feed system ensures smooth operation and low failure rates. These features give YG’s diamond wire saw machine a good cost-performance advantage among similar products, making it suitable for various demolition scenarios.


Diamond Rope Saw Case
Customer Background
In 2025, a medium-sized building demolition company in California, U.S., took on an old bridge pier removal project. The project required removing the remaining pier of an old bridge built in the 1960s—about 3.5 meters in diameter and 8 meters high, made of high-strength reinforced concrete, with part of it underwater. The company had previously used breakers and blasting, but this project was in an ecologically sensitive water area, where blasting was prohibited, and conventional mechanical cutting was difficult to perform precisely underwater.
Construction Challenges
The company faced three main issues: First, the pier was in water with strong currents and low visibility, making it hard for standard cutting equipment to operate stably underwater. Second, the pier had dense rebar inside, so ordinary cutting tools tended to jam or wear too quickly. Third, the project had a tight schedule—the owner required completion within 30 days.
YG Solution
After initial discussions, YG’s technical team designed a complete construction plan for the client: using the HM80 hydraulic wire rope saw with a 50meter diamond wire, driven remotely by a hydraulic power station, so operators could work from shore or on a boat. For underwater cutting, YG provided special waterproof guide wheels and sealed connectors to ensure stable operation underwater. To handle the dense rebar, YG selected high-concentration diamond beads to improve rebar cutting capability. The whole solution was configured around the core functions of the diamond wire saw machine, and included detailed cutting efficiency estimates and operating recommendations.
Case Process
Over two weeks, the two sides held three technical discussions and video meetings. YG provided equipment parameters, reference cutting efficiency data, and on-site operation precautions. The client compared the performance and price of YG’s diamond rope saw, and finally signed a purchase contract in August 2025, ordering two sets of wire rope saw and supporting consumables. After delivery, YG provided remote video guidance for installation and commissioning.
Results
Using YG’s diamond rope saw, the pier removal progressed as planned. Actual cutting efficiency was about 7.5 square meters per hour, and total cutting time for the single pier was about 19 hours—better than traditional breaking methods. The entire pier was removed within 24 days, meeting the owner’s schedule. The project manager reported that YG’s wire rope saw met cutting accuracy requirements, ran stably, and after-sales service responded promptly, effectively reducing the risk of project delays.
