EL3000

MUSCLEMAN FOR ULTIMATE PERFORMANCE IN HIGH SEAM APPLICATIONS

The EL3000 shearer has been developed for medium to high seams to meet the requirements of the most demanding longwall installations in the world. World-class performance has demonstrated the practical capabilities of this machine. The EL3000 provides a production capacity of over 5000 tonnes per hour (5,511 tons per hour), featuring heavy-duty, high mass for maximum stability and reliability in the most demanding applications

Top Specs

Seam Range
2.5-5.5 m; 98-217 in

Haulage Power
2 × 150 kW @ 50 Hz; 2 × 200 hp @ 60 Hz

Cutting Power
2 × 860 kW @ 50 Hz; 2 × 1,380 hp @ 60 Hz

Robust One-piece Mainframe

The fabricated structure of the unique one-piece 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.

Power for the Toughest Conditions

A total installed power in excess of 2000 kW (2,681 hp) provides high level of performance in the most arduous mining conditions. Fast and accurate positioning of the ranging arm through two-speed technology and improved powerful lifting cylinders.

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.
