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.
Not only are tanks being built to hold their contents more safely and securely than ever before, but they are expected to do it for longer and in more challenging operating environments where steel, concrete and fibreglass tanks need secure roofs that can withstand expansion and contraction caused by factors such as increasing climatic and load variations.
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 waste water utility and emergency services.
A cost-efficient solution to many such issues is offered by Hercules Engineering through its range of Herculon Type D Tank Top Bearings (HLD/TT) Bearings, which are custom-designed for easy installation under roof beams of tank tops and other lighter structures including some building roofs. These low-friction easy-slip bearings are particularly useful where loads are relatively small but both lateral and uplift forces need to be accommodated, says Mr David Booty, Manager, Hercules Engineering (a division of Cut to Size Plastics).
“Light but strong and flexible tank tops are now widely employed to protect tanks and their contents from external pollution ranging from flora, fauna, dust and droppings and water-borne impurity. The bearings used under these tops must not only support the structure, but also prevent it from cracking and breaking and becoming part of the pollution problem.”
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 per cent 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
Construction and performance characteristics
HLD/TT bearings consist of a thin stainless steel slide plate with two stainless steel studs flash 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.
Five stock sizes in working loads from 50-70 kN. Larger capacities and different dimensions can be custom-engineered.
Co-efficient of friction 0.05- 0.08, depending on stress
Expansion capacity up to ± 20mm (can be custom designed for larger movements)
Maximum rotation up to 0.01 radians
Maximum temperature 80 deg C
