GEARBOXES
Resisting fatigue and failures, Longwall Associates line of gearboxes are built for longevity. Extensive cooling systems greatly reduce the risk of overheating - which in turn, reduces wear, reduces corrosion and minimizes lubricant chemical property contamination and alteration. All of this means your Longwall Associates gearbox will operate consistently and precisely as designed. And during change-outs, rebuilds will require less work. On our gearboxes you will also find uniquely designed gears which enable substantial noise reductions. Upgrades are simple, too – Longwall 40 series gearboxes are directly interchangeable with other industry gearboxes. Over 200 years of engineering experience stand behind our gearboxes. The result is an OEM gearbox that outperforms others with the highest degree of reliability, functionality and durability.
Gearbox features:
- Absolute horsepower ratings
- Low profile design to minimize stack-up
- Innovative casting and design for increased rigidity
- Unique cooling system reduces temperature more efficiently than other gearboxes
- Change gears designed for quiet, smooth operation
SPROCKET ASSEMBLIES AND RINGS
Nowhere is Longwall Associates' acumen more evident than in its line of sprocket assemblies and sprocket rings. Incomparable in design and structure, Longwall Associates sprocket rings operate in the toughest conditions in the mining industry. Not only do they perform in rugged operations, they have been field-proven to actually increase production life, particularly over competitor units. Not stopping with design, we have developed exclusive materials that allow us to harden sprocket ring pockets deeper and harder than any other manufacturer. And during production, our unique machining process allows for the most accurate chain interface. These are just a few reasons why Longwall Associates sprockets are the choice for mines regardless of conveyor supplier.
- Suitable for all width conveyors
- May be lubricated with grease or oil
- Interchangeable between head and tail drive
- Quicker change-out than other industry units
- Field-proven success in the toughest mining conditions
- Capability to customize sprockets to meet any requirements
