The system weighs less so you can haul more.
Features reduced trailer weight for maximum payload plus multiple additions designed specifically for liquid hauling applications. With a total tank volume of 10,050 US gallons and aluminum trailer construction, this is a Super B designed with agriculture in mind.
TWIN MAXX FEATURES
The Tanks
The Twin Maxx includes twin 5,025 US gallon Norwesco horizontal leg tanks built to safely haul liquids up to 1.9 specific gravity. These tanks feature molded-in legs to reduce sloshing with additional liquid movement restricted by Liquid Surge Stabilizer retro-fit baffle balls.
With specially designed total drainage bolted fittings installed in the floor of the Twin Maxx, product drainage is maximized. Field tests have proven that these strategically located fittings drain 99% of the Twin Maxx with just one valve per tank to operate. Add to this our on-board suspension valves to assist with tank slope under most yard conditions, and you have one of the fastest and best emptying tanks in the industry.
The Plumbing System
The plumbing system features leak-free Banjo manifold fittings and valves that are vibration resistant and extremely easy to service. The pump options include a 3” Honda-powered Pacer pump complete with the Protec engine protection system or the 3” Honda-powered Banjo pump with a wet seal package to allow for complete run-dry protection. Each trailer has a separate pump and the tanks are designed for either bottom or top loading.
The Tank Valve
The unique main tank valve is accessible from immediately beside the main plumbing manifold. This valve features an extended valve handle that makes filling and emptying the tank easier than ever.
Optional Lift Axles
Optional* individually controlled lift axles can improve fuel efficiency and reduce emissions, prolong tire life, and reduce road damage if raised while the tanks are empty. On rough roads lowering the lift axles when empty can result in reduced bouncing.
* Please consult local regulations regarding the use of lift axles to determine suitability
Hose Management
Sometimes it is the little features that save you when you need them the most. The innovative hose management system on the Twin Maxx keeps the 30’ of hose supplied with each trailer firmly anchored and sealed during transport, protects the corrosion-resistant polypropylene camlock fittings and provides a safe and convenient area to secure your hose when not in use.
Tank Lids
The 16” hinged, vented lid was designed with hauling in mind. Hinged to prevent loss, lockable, easy to open yet secure in transport and virtually leak free, this is the lid that all tanks should have.
Trailer Ladder
Getting on and off of the trailer easily and safely is important. The Twin Maxx has a hinged aluminum ladder installed onto the fifth wheel platform between the two trailers that is slip resistant and lightweight, yet sturdy and durable.
ADFR System
Polywest’s own ADFR System is an industry leading method of securing tanks to decks. Designed specifically for the physical characteristics of polyethylene and aluminum, the ADFR System disperses all of the forces inherent in liquid loads to the structural frame of the trailer. This not only provides maximum load security, it also isolates both the trailer deck and the tank from any undue stress and point loading.
Tank Platforms
It is important that the access to the tank lid is easy and safe. With a slip resistant aluminum grate custom fabricated from SAFETY-GRIP® Channel, the Twin Maxx platform is securely attached to the support bands and makes for safe access to the top of the tank.
Tank Ladder
Both of the Twin Maxx’s 5,025 US gallon Norwesco tanks have double hinged, slip resistant ladders that, while securely fastened to the tank and the trailer deck, will flex with the trailer during transport. This feature eliminates stress on the tank, trailer and deck common on fixed ladder systems. The powder coated steel ladders also feature a durable adhesive membrane between the ladder and the aluminum deck that prevents corrosion due to diverse metal contact.
