Spring weight choice - (What DO the springs do ?)

Your only original concern should be the material weight found at the LOWEST part of your container.
Each patented spring moves the shelf a predetermined amount of distance by weight a max of 20".  
     All weight ABOVE 20" is already in the desired ergonomic working window anyways.

Fact:
Our (1") inch thick shelf is attached to spring tubes allowing a max of 20" of movement.
   *The fully loaded shelf sitting on the bottom of the container allows complete loading of the bin until all usable space of that bin is filled.
   *shelves are usually 2" square .135 wire mesh.  Other surfaces by request.
   *shelves are powder coated for durability.
   *Springs tubes are ID color code labeled-see below.
   *No reduction of container volume.

Define your needs,
please:
  *include all weight inside the container;
  Include product, anything that hold(s) or separates your product,
  plus anything that could be included/attached on/to the shelf. 

How do you determine the correct weight of springs to buy/use?
Let's use a possible job scenario.
A) Start with a 45" x 48" plastic molded basket. Inside usable depth measures 42”;
B) Drop down access doors are on two sides and measure 20” from the inside basket   
floor (prox 29.5" from the plant concrete floor);
C) Multiple product layers are packed, each separated by plastic corrugated dunnage;
D) Basket contents weight (all parts & dunnage) = 1000#;
E) The lowest 20" of product in the basket is about 550#.

Your new setup-how to figure this all out:
From the above information given, we would suggest a 600# spring setup (4-150# springs), see chart below, to be used. These four 150# spring inserted tubes will be attached to the bins' four corners via screws.  The shelf attached to these SEEL spring tubes will now lower or lift 600# in a very measured way.
Please call if there are ANY questions to get started correctly.
