Portable Storage PIGS

Mintek storage PIGS, sometimes simply referred to as PIGS, are large mobile tank trailers intended to store dry bulk powders like lime, Calciment® LKD, cement, bed ash, fly ash, other similar products or blends. Mintek PIGS are roughly the size of normal tractor trailers and can hold approximately 4 – 5 standard pneumatic loads of material, or around 100 – 120 tons. PIGS offer assurance of material supply to the jobsite, ensuring crews and equipment stay busy and projects stay on time. Mintek offers PIGS for lease to assist in keeping jobsites on track. PIGS are available on a first come, first served basis.

Close up of PIGS storage

Mintek PIGS have 4 product intake pipes, one at each corner, making it easy for delivery drivers to offload at virtually any angle via a standard flexible hose. Inside, a series of connected hoppers allow material to accumulate and disperse throughout the unit for storage. When material is needed on the site, a product delivery hose can easily connect the PIG to a spreader truck. Diesel or electric blowers pressurize the PIG and supply air to transport material while a series of valves allow the operator to control the pressure and material discharge rate. For stubborn materials, or grades of materials, that tend to pack in place, aerators, or fluidizers, introduce air through the substance helping to move the products. A filter medium, such as a filter sock, can easily be connected to the PIG to capture dust during depressurizing. Other safety features, including check valves, visible pressure gauges and pressure safety valves allow workers to maintain a safe working environment.

What are Portable Storage PIGS Used for?

Portable storage PIGS provide bulk storage where you need it most, at the jobsite. Each PIG can hold 4 – 5 standard pneumatic loads, helping to constantly supply material to a job when you need it. Unfortunately, many unforeseeable delays are often associated with material delivery. Mintek PIGS make these unfortunate headaches more bearable by holding onsite inventory of material in times of low availability. As an added value, Mintek PIGS can be utilized to accept material delivery when trucks are available, even if there are no work crews present. Having a storage PIG onsite minimizes the need to wait on product delivery and lessens the chance of delay due to lack of material on the jobsite. Mobile tank trailers keep jobs moving, helping you hit deadlines, save money, and keep owners happy.

Other Portable Storage PIG Considerations


These specialty tank trailers are designed to hold an impressive amount of material. However, they do need all support legs to be completely lowered and secured in order to bear the full weight when loaded.


Portable storage PIGS should be placed in an area that is hard and mostly level, allowing for water to drain away from the PIG. Ideally the location is somewhere that is away from pedestrian traffic and allows for easy access for delivery drivers.


If the ground underneath the support legs isn’t able to support the unit, larger feet can be furnished or simple pieces of wood can increase the surface area under each foot, allowing for a more stable system.


Portable storage PIGS are mobile, making them usable on almost any site. However, just because they are mobile doesn’t mean that they can be moved with material inside them. They must be emptied before moving to a different location on a site or before removal from the site.


Electric or diesel? Mintek PIGS come with mostly electric blowers already installed, with a handful of diesel blowers as well. If a separate generator is needed, it must have sufficient power to supply the blower.
