Herculon tank top bearings help meet increasing climate change and production challenges to liquid protection
Storage tanks today can hold upwards of 10, 20 or even 30,000 tons of liquid that must be protected from the elements and from pollution to safeguard it for use in water, waste water, emergency fire protection and high purity industrial processing applications.
A challenge facing developers and operators of buildings and processing plants for industrial and municipal uses is ensuring their top structures can flexibly cope with internal movement from climatically induced expansion, contraction and wind and rain forces, while also coping with production stresses caused by heavy and changing loads, vibration and other factors encountered within diverse industries. Relevant industries can include mining and energy, oil and gas, ports and infrastructure, food and beverage, primary processing, manufacturing, materials handling, water and wastewater utility and emergency services.
HLD/TT bearings are part of a proven range of Hercules composite slip joints and structural bearings for a wide variety of structures and weights incorporating engineered high performance combinations of engineered thermoplastics and metal facing surfaces. Complementary Type D Herculon Bearings HLD/SG are designed to accept a lateral load of 30 percent of the vertical rated load, which can be up to 600 kN per bearing in stock sizes, with higher capacity available custom-engineered for particular applications HLD/TT bearings consist of a thin stainless steel slide plate with two stainless steel studs f lash welded to the upper face. The lower face is highly polished and the plate is provide with two slotted holes for uplift through-bolts. This plate slides against a Herculon-coated Hercupad, which has two clearance holes drilled into it.
