Reusable, flexible, lightweight, low cost flexible intermediate bulk containers (FIBCs) for the delivery of granular proppant material for fracing that will allow the transport of higher weights of proppant, such as sand, per truck load. The invention includes a container made of a high strength, flexible material with a top opening for loading and deploying the proppant. The container can be lifted and deployed with a fork truck or crane. Alternatively, proprietary deployment systems, such as a conveyor system, can be used to quickly and efficiently deploy the proppant from the container at a desired site.

The present invention relates to a big bag having a body having a plurality of sidewalls, an open top end, a closed bottom end, and a perimeter, wherein each one of the sidewalls connects with an adjacent sidewall forming a corner; a plurality of handles, each handle is connected to a corresponding corner; and a central handle connected to a middle section of the closed bottom of the body, wherein the central handle protrudes from the perimeter of the body.

An extendable bag roller for supporting a bag of material during removal of the material from the bag includes a bag support having a curved surface configured to support the bag of material on the curved surface and a roller that rolls along the curved surface of the bag support to squeeze the material out of the bag. The bag support includes a base defining a first portion of the curved surface of the bag support and an extension defining a second portion of the curved surface of the bag support, the extension being moveable to selectively increase and decrease the area of the curved surface of the bag support to accommodate different bag sizes.

A container to be used with trucks, semitrailers, railway wagons and ships, so as to carry out a multimodal transport where the transport by land, railway and fluvial routes is combined as needed. The container has a metal parallelepiped structure which contains a truck bed receiving the material, and one end it is mounted over a hinging resource that allows its turn regarding a lower cross axis; and at another end it is connected with a hydraulic cylinder that is fixed over the basis of the mentioned metallic structure and has its end free of its piston linked to the upper and rear cross edge of the truck bed.

A construction material transport container includes four side doors that form substantially all of two side walls of the container. The container includes transversely disposed forklift pockets that can be used to load the container onto a flatbed truck. With the container on a truck and the side doors open, new construction materials can be loaded onto the container from both sides. Both the container and the new materials can be delivered to a job side by a single delivery using a truck-attached forklift. The empty container can then be used as a receptacle for recyclable materials. The container further includes roll-off or hook lift vehicle tracks configured so that the container can be picked up and hauled to a recycling or refuse center. A rear door of the container can be opened so that the container can be tilted by the vehicle to offload the used material.
