TBM Cutter

Tunnel boring machine cutters referred to as "TBM Cutters", are excavation tools installed on the cutter heads of tunnel boring machines and shield machines, which include TBM disc cutters (single disc cutter, double disc cutter, twin disc cutter) and soft ground cutters (eg. scrapers, cutting knives, buckets, rippers and other cutting tools). These types of disc cutters and soft rock cutters, in different sizes and specifications, can also be used on MTBM, pipe jacking machines, and other similar rock-breaking equipment.

Litian has been focusing on the development of TBM cutters and solutions suitable for various rock conditions, and we have made remarkable achievements in helping users improve tunneling efficiency and reduce overall costs. Litian has now developed into the largest supplier of TBM disc cutters in China.

Litian TBM cutters can be used on Microtunnelling Machine (MTBM), Earth Pressure Balance Shields (EPB Shield), Mixshield, Single Shield TBM, Double Shield TBM, Gripper TBM, Multi-mode TBM, Pipe Jacking Machine, Shaft Boring Extension Machine (SBE), Shaft Boring Machine (SBM), Small Boring Unit (SBU),..., with a cutter head diameter ranging from 0.8m-15m.

What's the package for TBM cutters?

TBM cutter packaging: Cutters are packed in a solid plywood box, which complies with national packaging regulations. It meets the needs of transportation, handling, moisture-proof, rain-proof, and rust-proof. It can ensure that the goods arrive at the site in a safe and non-destructive manner.

Can you provide TBM Cutter Consumption Estimation for project? And what information needs to be provided?

We can estimate the TBM cutter consumption based on the TBM information (such as TBM maker, type, cutter head diameter, initial dress of cutting tools, etc), 

project information (tunnel length, excavating Diameter, etc ), and geological conditions information (such as rock hardness, quartz content, massiveness of rock mass, fissure coefficient, etc).
