Martin® GravitySeal™ Self-Adjusting Skirting delivers a reliable skirtboard seal that prevents spillage and reduces issues caused by fugitive material. The system automatically adjusts to maintain an effective seal, eliminating the need for skirtboard maintenance.

Martin® GravitySeal™ Self-Adjusting Skirting Maintains Effective Seal Without Maintenance
A salt plant in Ohio was looking to upgrade their skirtboard sealing systems. The existing slab rubber skirting was in bad repair and leaking material. With less than two inches (51 mm) of free belt area on each side of the loading zone, the conveyor had very limited amount of space available for installation of a sealing system.
Martin® GravitySeal™ Self-Adjusting Skirting Faster And Easier To Install
At cement company, abrasive clinker would rapidly wear out the skirtboard sealing strips, creating a severe spillage problem at the conveyor’s loading zone. The sealing system required replacement every three weeks. Martin Engineering provided “Personalized Performance” by tailoring the Martin® GravitySeal™ Self-Adjusting Skirting to provide improved corrosion resistance while remaining within the customer’s budget.
Belt Sealing Products Reduce Cleanup and Maintenance Costs
Located on the Ohio River, the Mt. Vernon Transfer Terminal moves approximately 1.8 million tons of coal annually from trucks or railcars to barges for shipment to power plants. Excessive spillage from an underground belt below the railcar dumper increased cleanup costs and maintenance headaches. This conveyor is 84 inches wide with an operating speed of 150 fpm.
