2024 Komatsu 21SC04 Base

2024 Komatsu 21SC04

Built for low seam batch haulage

Designed for maximum production in low-seam applications with a robust drive system and reduced maintenance with a Joy OptiDrive AC variable frequency drive, due to no commutator brushes to inspect or replace.

Features may include:

• Designed for reliability with heavy-duty conveyor reducers and abrasion-resistant decking and chassis and rolling gears designed for optimal balance of volumetric load, vehicle dimensions, load-carrying ability and fatigue life.

• For uneven or broken roadways, Joy shuttle cars’ four-wheel independent suspension mitigates energy transferred to the chassis, designed for longer machine life and to help reduce operator fatigue.

• With a swing-out controller and swing-out pump compartment, easy access to hose and cables helps reduce maintenance time. Lighting options and zoned-out difficult-to-access grease points further facilitate maintenance.

• Variable frequency drive (VFD) conveyor reduces the shock loading of all key conveyor drive components to help ensure the reliability and availability of the conveyor system. Operators can adjust discharge rates to match the mine belt infrastructure.

• All-time four-wheel drive system helps performance on soft bottoms and grades. Powered by two 85kW VFD AC traction motors (50 kW in lower seam models).
