Unique: One-piece machine frame
The single fabricated structure of the mainframe with cast hinge points for ranging arms results in an extremely robust design providing optimal protection to drive and control units. This sturdy heavy frame is also the ideal anchor against the forces occurring during driving of the shearer and cutting of coal or other minerals.
 
Modular design
The design of the shearer allows modular use of standardized subassemblies. This facilitates customization of the shearer and rapid replacement of modules during maintenance, minimizing downtime and allowing long-term calculation of operating costs.
 
Haulage system
The various haulage systems for the Electra® shearers are designed for problem-free operation under even the most difficult geological conditions. Design and material selection is undertaken to achieve highest possible system availability, maximum service life and high efficiency. Haulage speeds of up to 60 m/min support mining rates of up to 5,000 t/h.
 
Next-generation automation
The COMPACT shearer control system for the Electra® shearer controls, monitors and protects all shearer components. Its modular design allows it to be configured to meet individual control needs. The CAN bus system reduces shearer wiring by up to 70% and facilitates later addition of components for future applications. The ergonomic design of interfaces and comprehensive machine diagnosis and automation functions allow highest production rates, day in day out. High availability and production records are an impressive demonstration of our leading position.
