A diamond wire saw is a hydraulic wire saw for cutting thick reinforced concrete, bridge piers, wharf platforms, and underwater piles. This concrete wire saw can cut in any direction and reach depths that wall saws cannot. It cuts with no vibration and keeps the original structure safe. For bridge demolition, pier removal, and underwater cutting, this wire saw cutting machine is the right tool.
YG Machinery makes reliable wire saw machine for bridge demolition, pier removal, and underwater cutting projects.

Main Structure of Hydraulic Wire Saw
A hydraulic wire saw has three main parts:
Hydraulic Power Station – This provides power for the whole wire saw cutting machine. It has a 22/25KW motor and works on 380V 50Hz. The oil tank holds 16L of hydraulic oil.
Wire Saw Unit – This holds the diamond wire and drives it to cut. The unit weighs 64kg and can hold up to 18 meters of wire.
Diamond Wire – The wire has diamond beads that cut through concrete and rebar. Water or oil cools the wire during cutting.
This diamond wire cutting machine is designed for heavy demolition work.
Cutting Depth Not Limited
Unlike wall saws, this wire saw for concrete has no cutting depth limit. It can cut through entire bridge piers, thick wharf platforms, and large concrete blocks. The wire can be extended to 18 meters or more. This makes the diamond wire saw the only choice for cutting oversized concrete structures.
Cut in Any Direction
This wire saw machine can cut horizontally, vertically, or at any angle. It works on walls, floors, ceilings, and irregular shapes. The wire can go around corners. This flexibility is important for bridge demolition and underwater pile cutting where access is difficult.
No Vibration, No Structure Damage
The diamond wire saw cuts with static force, not impact. There is no vibration. The original structure stays intact and undamaged. This is critical for cutting bridge piers and underwater piles where you only want to remove part of the structure and keep the rest safe.
Underwater Cutting Capability
This underwater wire saw can cut concrete piles 30-50 meters below water. It works on wharf platforms, underwater bridge foundations, and submerged concrete structures. The hydraulic power station stays on land. The diamond wire goes into the water. No special diving equipment is needed for operation.
Applications of Bridge Cutting Wire Saw
This bridge cutting wire saw works well in many jobs:
- Bridge demolition and removal
- Bridge pier cutting
- Wharf platform demolition
- Underwater concrete pile cutting
- Cutting reinforced concrete beams and columns
- Cutting equipment foundations
- Cutting thick concrete walls and floors
- Cutting irregular concrete structures
The machine can cut underwater up to 30-50 meters deep.
Working Principle
The hydraulic power station sends oil to drive the motor. The motor spins the drive wheel. The drive wheel moves the diamond wire at high speed. The wire grinds through concrete and rebar. Water cools the wire and controls dust.
Customer Case – Concrete Wire Saw in Action
A construction company needed to remove old bridge piers in a river. The piers were 2 meters thick with heavy rebar. A wall saw could not reach around the pier. The team used a YG hydraulic wire saw.
The diamond wire wrapped around the pier and cut through from both sides. The cut was smooth. No vibration damaged the rest of the bridge. The job was finished on time.
The project manager said the wire saw cutting machine made the job possible where other tools failed.
Maintenance Tips
- Check the diamond wire before each use. Replace if beads are worn.
- Check hydraulic oil levels. Add oil if low.
- Clean the wire saw machine after cutting. Remove concrete dust.
- Inspect hoses for leaks.
- Store diamond wire in a dry place.
Good maintenance makes your diamond wire cutting machine last longer.
Frequently Asked Questions (FAQ)
Q: How deep can this diamond wire saw cut?
A: Cutting depth is not limited. It can cut through entire bridge piers and large concrete blocks.
Q: Can this hydraulic wire saw cut underwater?
A: Yes. It can cut underwater concrete piles up to 30-50 meters deep.
Q: Does it damage the original structure?
A: No. It cuts with no vibration. The original structure stays safe and undamaged.
Q: What is the maximum wire length?
A: The wire saw cutting machine can use up to 18 meters of diamond wire.
Q: Can this wire saw for concrete cut reinforced concrete?
A: Yes. The diamond wire cuts through concrete and steel rebar easily.
Q: What is the cutting efficiency?
A: One meter of diamond wire can cut 2-3 square meters of concrete.
Q: Do I need water for cutting?
A: Yes. Water cools the wire and controls dust. For underwater cutting, water is already there.
Q: Is this bridge cutting wire saw better than a wall saw?
A: For thick concrete, irregular shapes, and underwater work, yes. A wire saw can cut where a wall saw cannot reach.
