High-load industrial transmission system engineered for mining conveyor operations. Designed for 24/7 continuous duty in extreme underground and surface mining environments.
Engineered for the world's most demanding industrial environments — from open-pit mines to underground tunnels.
Ore transport conveyors, bucket wheel reclaimers, stackers and ship loaders
Continuous miners, longwall conveyors, shaft hoists and ventilation fans
Raw meal conveyors, kiln drives, cooler grate drives and clinker handling
Rolling mill drives, coil handling conveyors and hot metal transport
Bulk ship loaders, unloading conveyors, stacking and reclaiming systems
Engineering decisions based on operational reliability — not component cost reduction.
Two-stage planetary helical gearing delivers consistent torque up to 400,000 Nm. Case-hardened and precision-ground teeth maintain meshing accuracy over 50,000+ operating hours.
Optimized gear tooth geometry reduces power loss by up to 18% vs. standard designs. For a 315kW conveyor drive running 24/7, this saves ~$12,000/year in electricity costs.
Ductile iron housings with finned construction handle radial and axial shaft loads from conveyors with variable tension. Custom bearing arrangements prevent premature failure from shock loads.
Double-lip output seals, labyrinth input seals and IP65 housing protection prevent contamination in high-dust environments. Industrial-grade bearings rated for 50,000 hour L10 life.
Modular housing design allows bearing and seal replacement without removing the gearbox from the conveyor. Common component series across all sizes reduces spare parts inventory.
Standard range: −15°C to +45°C. Extended range models with thermal compound housing and synthetic lubricants operate reliably in hot underground mines up to 55°C ambient.
Understanding the power flow from motor to conveyor drum — and why our design outperforms standard gearboxes in mining conditions.
Our mining conveyor gear reducer uses a two-stage planetary helical architecture. The first stage reduces speed using planetary gears (sun, planet and ring gear arrangement), which distributes load across multiple planet gears for exceptional durability. The second stage uses helical gears for smooth, quiet operation at high reduction ratios.
