Loading, Chimney Block Style
In the produce transportation industry, trailer pallet configuration and loading patterns can differ depending on the type & weight of the product, and the number of pallets required on the trailer. Chimney blocking is one common way that many produce loads are arranged in a trailer, so let’s look at it in more detail.
Chimney blocking is the process of loading pallets into a trailer by putting one in straight and one turned, and altering this pattern, to make the most out of the space.
Trailers requested to be loaded via chimney block pattern generally do not have to take into consideration the weight of the product, so it is often used for loads of lettuce and other leafy greens. Chimney block pattern loading is commonly used when 26 – 28 pallets of product need to be loaded on the trailer.
Below is a visual of how chimney block loading will look, with standard 40”x48” pallets (classic wood treated and CHEP pallets are all 40”x48”): (*note: a 48’ Trailer shown).
As always, loading of product into trailers should comply with DOT weight and axle distribution requirements; total gross weight cannot exceed 80,000lbs. Also, whatever loading pattern is used, it is optimal that the product is centerline loaded; this means that the pallets and product will not touch the trailer walls and will therefore not be affected from the outside air temperatures that are conducted through the trailer walls (very important during the hot summer months!). Also, the pallets must be loaded in a way that allows for adequate airflow throughout.
So, there we have it, a quick sweep of chimney block loading pattern!!!! Have a great weekend!
