A 1000 gallon black elliptical cradle tank for a nurse trailer or a truck frame
The Norwesco 1000 gallon horizontal elliptical cradle tank in black, part number 41361, is a polyethylene transport tank with a flattened oval cross section and no legs: it is shaped to ride in a steel cradle on a trailer or a truck frame, which keeps a thousand gallons low and spreads the load along the whole length of the shell. The tank is 90 inches long, 78 inches wide and 55 inches tall, and weighs 284 lb empty. It comes with a 2 inch polypropylene female NPT bulkhead fitting as the outlet and a 16 inch threaded vented manway on top. The tank is rated for liquids up to 1.5 specific gravity, a maximum of 12.52 lb per gallon, which covers water, most liquid fertilizers and many common chemicals; 1000 gallons of water weighs 8340 lb. The resin is FDA compliant per Norwesco and the service limit is 120 F (48 C). Black keeps light out of the contents, which slows algae in water and protects light sensitive liquids.

Why a cradle tank instead of a leg tank
A leg tank carries its load on a few moulded feet; a cradle tank lies in a saddle that supports the lower half of the shell continuously, which is how a tank this size is meant to travel full on a road. The elliptical shape puts 1000 gallons in 55 inches of height, lower than a round tank of the same volume, so the centre of gravity stays down and the tank clears more. Fertilizer dealers and growers use it as a nurse tank behind the planter, custom applicators as the supply tank on a tender trailer, and contractors as a water tank on a flatbed. No cradle is listed with this tank, so tell us whether you have one; the cradle must match this shell's profile, and the drawing linked on this page under Technical Drawing shows it. Full of water it carries 8340 lb on top of the 284 lb tank, which decides the trailer's axle rating before anything else. Strap over the shell into the cradle, never over the manway.
What goes in it
Liquid fertilizer, water and the common farm and treatment chemicals that polyethylene handles. Check the liquid in our chemical compatibility guide before the first fill; the entries for urea solution, DEF, calcium chloride, sodium hypochlorite and phosphoric acid are the ones buyers of a nurse tank ask about most. Liquids heavier than 1.5 times water need a heavier rated tank; tell us the product and we will point you to one. Keep the contents under 120 F. For the volume, use the tank sizing calculator and tank sizing guide.
Openings and fittings
- Outlet. A 2 inch polypropylene female NPT bulkhead fitting, factory installed. Your valve, camlock or hose adapter threads straight in. Support the valve and the first length of hose on the trailer so the fitting carries liquid, not hardware.
- Manway. A 16 inch threaded vented manway on top, wide enough to fill from a hose or a pump, drop a float in and get a brush inside.
- Drawing. Norwesco's drawing for this tank, linked under Technical Drawing on this page, shows the shell profile for the cradle, the outlet position and the manway position.

Shipping and receiving
The tank ships LTL from Norwesco's St. Bonifacius, Minnesota or Washington Court House, Ohio plant, 90 by 78 by 55 inches and 284 lb on the pallet. The listed price is before freight; the freight cost estimator gives the lane cost to your ZIP. At 78 inches wide it needs a forklift or a loader to unload. Check the part number against 41361 on the bill of lading, walk round the shell for transit damage, set it in its cradle, and fill it with water the first time before it carries anything else.
