EPB Series

  • Wide range of applicable geological conditions.
  • Adopting a low speed and high torque transmission mode with greater excavation force, the over-load coefficient can reach over 2.
  • Independent and perfect water injection and grouting system improve the excavation surface soil condition to expand the scope of application.
  • The ground settlement is low, and the minimum soil cover depth is only 1.2 times the pipe diameter.
  • The cutterhead adopts a central support type, with a compact structure, light weight, long service life, and easy maintenance.
  • Unearthed by the screw conveyor, with a large excavation amount and large particle size.
  • By utilizing advanced electrical systems to control deviation correction, the correction amount can be intuitively displayed digitally, with sensitive response and convenient operation.
  • Full-face cutting with extremely high opening ratio.

Frequently Asked Questions

To become a first-class international machinery manufacturing enterprise.
What are the technical specifications of the GS1600-LS?

The EPB Series has a wide range of applicable geological conditions including silt, sand, and clay layers. It's suitable for diameters from 1500-4000mm.

The GS1600-LS is a 160-ton class hydraulic directional drill delivering 1,700KN pullback force with 78,000Nm rotational torque. Powered by a 316kW engine, this precision HDD machine is engineered for demanding trenchless technology applications requiring high accuracy and reliability.

What is special about the EPB Series' transmission system? What is the rock drilling system capability?

It adopts a low speed and high torque transmission mode with greater excavation force. The overload coefficient can reach over 2, providing exceptional excavation power.

The proprietary mechanical rock drilling system penetrates consolidated bedrock with minimal drilling fluid requirements. Designed for formations where conventional mud-based HDD methods are inefficient or impractical.

How does the EPB Series control ground settlement?  What are the hydraulic system specifications?

The machine maintains low ground settlement, with a minimum soil cover depth of only 1.2 times the pipe diameter, making it suitable for shallow depth construction.

German-imported closed hydraulic system operating at 35MPa maximum pressure. 4-inch mud flow channels for effective cuttings transport. The system is engineered for extended operation in high-demand drilling conditions.

What is the excavation method of the EPB Series? What geological conditions is the GS500GAT/AT-LS designed for?

It uses full-face cutting with an extremely high opening ratio. Excavated soil is transported by a screw conveyor, allowing for large excavation amounts and large particle sizes.

Consolidated bedrock, fractured rock formations, unstable alluvium, mixed geology, and high-permeability formations. The machine handles formations requiring high pullback forces and advanced mud circulation systems.

How does the EPB Series adapt to different soil conditions? What is the onboard lifting capacity?

The machine features an independent and perfect water injection and grouting system that improves excavation surface soil conditions, expanding its scope of application across various geological formations.

Integrated 5-ton crane handles drill string assembly, pipe sections, and tooling changes without auxiliary equipment. Eliminates separate crane mobilization for standard operations.
