Hook Lift Container - Tub Style
The tub style hook lift container puts a radiused bottom on a hook lift box, so wet waste, sludge, and sticky material slide out on the dump instead of packing into the corners. The rounded lower section has no corners for food waste and wet organics to collect in, and the smooth interior finish makes washout between loads quicker. An interior epoxy lining is available for corrosive loads. Standard steel is 10 gauge with a 7 gauge option. Food processors, wastewater treatment plants, municipal organics programs, and restaurants with high-volume wet waste are the typical users. Sizes run from 10 to 30 cubic yards, compatible with Galbreath, Stellar, SwapLoader, and the other major hook lift systems.

Custom Floor Lengths
The tub is built on the same floor lengths as our flat front hook lifts. A 20-yard tub on a 14-foot floor has taller walls, better for dense or wet material and tight-access sites. On a 22-foot floor the same 20 yards sits in a lower box that is easier to load by hand. Tell us the material and the site, and we will spec the length.
Specifications
A hook lift tub style container is a roll-off box with a curved, radiused bottom profile designed for wet waste, loose material, and anything that clumps, sticks, or retains moisture. The rounded lower section eliminates the 90-degree corners where sand, sludge, food waste, and fine demolition material pack in and harden. Material slides out on the dump, and washing it out between loads is quick.
What Is a Hook Lift Tub Style Container?
A tub style hook lift container looks similar to a standard flat-front hook lift box from the outside, but the interior bottom is formed into a smooth curved radius instead of flat steel with welded corner seams. That curved profile is the functional difference. When you dump a flat-bottom container, wet or sticky material tends to stay in the back corners. A tub bottom lets the load roll toward the rear and discharge completely. The result is cleaner dumps, less manual cleanout time, and less odor buildup between loads. Like all hook lift containers, the tub style loads and unloads via a hydraulic arm on the truck, which hooks onto a bar at the front of the container and lifts it on and off the bed. Compatible with Galbreath, Stellar, SwapLoader, and all major hook lift systems.
Best Applications for Tub Style Hook Lift Containers
Sand, dirt, and soil: loose granular material tends to settle into the rear corners of a flat-bottom container. The tub profile eliminates that pocket and allows full discharge without hand shoveling. Demolition fines and scrap screenings: material like broken concrete aggregate, masonry dust, and fine C&D debris behaves like wet sand during dump, and the tub radius clears it out. Food processing and organic waste: food processors, composting operations, and restaurants with high-volume wet waste disposal use tub containers because the smooth interior can be pressure-washed between loads. Wastewater biosolids and sludge: the radiused bottom handles high-moisture, cohesive material that adheres to flat steel. Municipal organics programs: municipalities running wet organics collection routes specify tub style for the cleanout advantage on tight collection schedules. The tub style does not have a rear door; it is a dump-only discharge design. If you need to load material from the rear or walk inside the container, use a flat-front or heavy duty model.
Tub Style Hook Lift Container Specs and Sizing
Cooper Tank tub style hook lift containers are available in 10 to 30 cubic yard sizes with custom floor lengths from 8 to 23 feet. The standard build uses 10 gauge steel plate with an optional upgrade to 7 gauge for higher-abrasion loads like demolition fines and scrap screenings. The interior smooth finish is standard on all tub models. An optional epoxy lining adds corrosion resistance for acids, chemical waste, and brine applications. The integrated hook bar is mounted on a structural frame, compatible with all major hook lift systems. Rear swing doors are standard with cam-lock latches. The tub profile also makes the container stackable, since the curved bottom nests when stored in the yard. Each size is available in multiple floor lengths, which changes the wall height and loading profile without changing cubic yardage. A 20-yard tub on a 14-foot floor has taller walls; the same 20-yard on a 22-foot floor has lower walls and is easier to load by hand.

Cooper Tank tub style containers are available in 10 to 30 cubic yard sizes with floor lengths from 8 to 23 feet.
What materials are tub style hook lift containers used for?
Tub style hook lift containers are used for wet waste, sand, soil, demolition fines, food processing waste, organic waste, biosolids, and other materials that retain moisture or pack into corners. The radiused bottom allows complete discharge without hand cleanout. These are dump-only containers with no rear door loading.
Do tub style hook lift containers have a rear door?
No. The tub style is a dump-only discharge design. Material is discharged by dumping the container, not through a rear opening. Rear swing doors are not standard on tub style containers. If you need rear-access loading, use a flat-front or heavy duty hook lift model.
What sizes do tub style hook lift containers come in?
Cooper Tank tub style hook lift containers are available in 10, 15, 20, 25, and 30 cubic yard sizes. Each size is available in custom floor lengths from 8 to 23 feet. The floor length changes the wall height without changing the cubic yard capacity.
Are tub style hook lift containers compatible with all hook lift trucks?
Yes. Cooper Tank tub style hook lift containers use an integrated structural frame hook bar compatible with Galbreath, Stellar, SwapLoader, Ampliroll, and all other major hook lift systems.
