Features and benefits

GPL9577.psd

Robust Linepans

Simple design – just four parts – for longevity. Trapezoidal design and a patented loading profile mean excellent horizon and snake control for standout alignment and face control. We rigorously test each bespoke AFC design before delivery.

OptiDrive variable speed drive (VSD)

OptiDrive controls everything from start-up to event mitigation, reducing chain travel by up to 40% to help improve product life and drive the path to zero harm. Variable chain speeds promote increased capacity, improved cutting cycles, and greater efficiency.

Joy gearboxes

Joy AFC gearboxes are specifically designed for AFC operations to promote enhanced production, quality and easy maintenance. Excellent space adjacent to the transmission, coalface and roadways. Overhaul and rehanding are designed in for lower cost refurbishment.

RS20s AFC Control system

More control is in your operators’ hands, as the RS20s standardizes the control system across all Komatsu longwall products. It can operate as a standalone system or integrate with powered roof supports and shearers. Commonality promotes easier parts management, maintenance and product support.

Turbo Transmission Technology (TTT) coupling

You can count on this controlled fill coupling. There’s no loss of torque under normal voltage drop situations and with no bearings or seals, very little maintenance and cost is required. It uses water as the fluid medium, making multiple hard-starts in succession possible.
GPL9319.jpg

Beam stage loader and belt tail end

Creates a seamless transition from face to belt to minimize the risk of blockages and provide excellent discharge to the conveyor system. Continuously moves to provide the necessary overlap to suit mining conditions.

Integrate with crushers

For excellent productivity, you need crushers to handle lump coal and oversize rock. A full range of Komatsu BSL crushers integrate with the AFC, made with heavy steel plate reinforced with beefy ribs. Direct gear-drive or a V-belt drive.
Support you can count on

Technology that works as hard as you do

Joy OptiDrive
The Optidrive variable speed drive system is the result of a holistic approach to transmission design that provides you with an adaptable, rugged and reliable solution for Armored Face Conveyor systems. The medium voltage (MV, 3300 or 4160 V) OptiDrive system integrates the variable speed drive with the motor to achieve outstanding speed and torque control for soft starts and stops and fast acceleration. The variable chain speeds allow your operators to adapt to production conditions, giving you an opportunity to increase capacity, improve cutting cycles, and achieve remarkable efficiency with your longwall system.
