Cutting Power
2 × 500 kW @ 50 Hz; 2 × 805 hp @ 60 Hz

Highest Structural Integrity

The unique mainframe of the HBT shearer is one of its key features. The fabricated structure of the mainframe with cast ranging-arm hinge points results in an extremely robust design not only to meet the toughest mining conditions and ensure reliability and long service life, but also to handle even higher cutting and haulage forces in the future.

Maximum Coal Cutting and Coal Clearance

Based on proven design concepts, the EL2000 ranging arm delivers maximum cutting power in an application-focused profile. The advanced machine design allows a high level of coal clearance for optimum loading performance.

Advanced Automation

The HBT PMC-S control system delivers efficient control of the shearer. The modular design allows individual configuration – from basic monitoring and protection to advanced automation and data transmission.
