In a Dock Lift Installation what are protective bollards?

Protective bollards serve the same function as loading dock bumpers. When the truck is backed into position bollards or loading dock bumpers stop the incoming truck movement and protect the loading dock equipment from damage. As many dock lifts are installed ahead of the building foundation steel bollards are typically poured into position to keep the truck from impacting the dock lift. Steel bollards are often 6” – 8” in diameter, typically installed approximately 4’ above grade and 4’-6’ below grade cast in concrete, secure enough to take vehicle low speed impact. The bollards are filled with concrete and often rebar is then inserted. The top of the bollards concrete has a slight crown to assist with water run-off.

What are the applications and steps for hot dip galvanizing?

Hot dip galvanizing is often specified in highly corrosive or repeated wash down applications. Common applications would be food processing facilities and chemical processing facilities. Preparing for the hot dip galvanizing process the equipment is built, tested then dismantled and sent to the galvanizer in sub-assemblies. The sub-assemblies are first dipped into an acid solution for cleaning, once cleaned dipped into a hot (approximately 850 degree) molten zinc galvanizing solution. The extreme heat of the galvanizing solution and the immersion process ensures that the complete sub assembly receives a protective coating. The sub-assemblies are then returned and the equipment re-assembled, tested and shipped.
