Longevity, Strength and Reliability
A weighbridge can have a very tough life, often in extremely arduous conditions. It only takes a short time before a poorly designed and inadequately protected weighbridge will show signs of deterioration, which eventually will affect its performance and reliability.
Construction:
Shering weighbridges are constructed using a monocoque design principle, whereby the weighbridge deck plates, which can constitute 40% of the overall weight, becomes part of the structure rather than a load being permanently exerted on the structure. All Shering weighbridges are seam welded, rather than spot welded. This ensures that all stresses are spread across the structure, rather than concentrated on the points of a spot weld. This type of welding helps prevent the ingress of moisture and dirt between the steel sections with resultant corrosion and weakening.
Shering weighbridges are built using quality controlled and certificated British Steel with rolled steel sections of more than adequate depth to prevent any flexing when loaded. In addition we position the crossmembers at no more than 500mm intervals, rather than the conventional 750mm (depending on the model chosen). We will only sell you the model of weighbridge strong enough for your needs.
Protection:
The high capacity load cells Shering use in our weighbridges are all fully welded stainless steel and sealed to either IP67 or IP68. (IP stands for Internal Protection and the rating is determined by the cable entry design. The IP67 version is usually a compression gland fitting while the IP68 has a glass to metal seal, the IP68 being more suited to very hostile environments and can be totally submerged in water without damage.) The cables from all Shering weighbridge load cells are enclosed in Kopex conduit, which is impervious to wind, water and rodents.
All Shering weighbridges are supplied with a 2-pack epoxy (MIO) protective coating, with the Gold range providing extended durability by increased surface preparation of the steelwork prior to the final coating. The steelwork on the Gold range is blast-cleaned to Swedish Standard SA2.5 and painted with a 2-pack epoxy zinc phosphate weldable primer. The top coat is a durable, high performance, high solids 2-pack epoxy system with MIO (Micaceous Iron Oxide) for the best resistance to corrosion.
The advantages of this finish on our Gold range are:
- High performance coating with excellent adhesion
- Exceptional corrosion protection in industrial and marine environments
- Chemical resistance to splash and spillage
- Resistance to the effects of fume and immersion in neutral fresh and salt water
- Excellent re-coatability
- Subject to certain conditions we guarantee our Gold weighbridges corrosion protection system for 10 years
Typical applications in which this protection has been well proven are:
- Bridges, tank exteriors
- Offshore platforms, ships, barges
- Oil tanks, piping, roofs, water towers
- Steel structures in industrial facilities
The standard protective finish, as used in the Bronze weighbridge, consists of the 2-pack epoxy MIO applied directly to manually prepared bare steel.
The epoxy finish coat is black with a low sheen and metallic sparkle. Alternative finish coat colours can be quoted for on request.
