This is our most popular accessory. It is most often used as a trash bin, where it is filled at an upper level and the crane operator can then move it to a dumpster and dump it without any help or assistance. It's well thought out design is built so that the inside dimensions are 4' x 8'. You can move pallets of material, 4x8 sheets of lumber or sheetrock, and anything else you can come up with. The box is aluminum and lightweight but can handle up to 2500 lbs, or 3 cubic yards. We serve the Northwest with Self-Erecting and Top Slewing Tower Crane Rentals.
