A 500 gallon yellow elliptical cradle tank for a sprayer frame or a trailer
The Norwesco 500 gallon horizontal elliptical cradle tank in yellow, part number 40369, is a polyethylene tank 82 inches long, 57 inches wide and 44 inches tall, weighing 154 lb empty. The elliptical cross section keeps the centre of gravity low and the lid within reach, which is why these tanks go on sprayer frames, nurse trailers and truck decks where a round tank of the same volume would ride too high. It comes with a 1.25 inch outlet and a 16 inch lid on top. Norwesco rates it for liquids up to 1.5 specific gravity, which is 12.52 lb per gallon; 500 gallons of water weighs 4170 lb. The resin is FDA compliant per Norwesco and the service limit is 120 F. Yellow is the colour fleets pick when the tank has to be seen and told apart from the water tanks.

Where it goes
A cradle tank has no legs. It is shaped to sit in a cradle or saddle that follows its curve, and that frame carries the load to the deck or the chassis. No cradle is listed with this tank; if you are building the mount, work from the Norwesco drawing linked on this page under Technical Drawing, and if you want us to source a cradle, say so when you call. At 82 by 57 inches it fills the width of most trailer decks, and at 44 inches tall the lid is reachable from the deck. Full of water the tank and its load come to more than two tons, and more with fertilizer, so check the axle and tongue ratings of whatever carries it before the tank, not after. Strap through the cradle, never over the lid. The tank sizing calculator and tank sizing guide help if 500 gallons is a guess rather than a number you have worked out.
What goes in it
Liquid fertilizer, water and the crop and treatment chemicals that polyethylene handles. Check the product against our chemical compatibility guide before the first fill; the entries cradle tank buyers ask about most are urea solution, DEF, calcium chloride, magnesium chloride and sodium hypochlorite. Liquids heavier than 1.5 times water need a heavy duty tank, and nothing hotter than 120 F should go in.
Openings and fittings
- Outlet. 1.25 inch. Norwesco's listing gives the size and not the fitting type, so if the connection matters to your pump, call before you order and we will confirm what the tank arrives with. Support the valve and the first length of hose so the fitting carries liquid, not hardware.
- Lid. A 16 inch lid on top: wide enough to fill from a hose or a nurse line, to drop a float or a suction line in, and to get a hand and a brush inside to clean.
- Drawing. Norwesco's drawing, under Technical Drawing on this page, gives the fitting position and the curve of the shell for building or matching a cradle.
