The RocknRoller Multi-Cart R9 "Mighty" is an ultra-versatile, heavy-duty 8-in-1 folding equipment cart engineered for ergonomic, all-terrain performance. Built from high-strength, textured powder-coated steel, the R9 instantly transforms into any of eight configurations - from compact flatbed dolly to extended high-stacking hand truck - making it the go-to transport solution for AV techs, DJs, live sound crews, film and TV location work, trade show exhibitors, mobile installers, and maintenance teams moving medium-to-large loads across unpredictable terrain.

At the heart of the R9 are its Groundglider wheels: 8" x 3" no-flat rear wheels and 6" x 2" front swivel casters, both mounted on steel ball bearings, that roll smoothly over grass, gravel, and dirt while keeping the frame bed roughly 20% lower to the ground than standard carts for easier loading and a lower center of gravity. The telescoping frame extends from 34" to 52" and carries up to 500 lbs or 32 cubic feet of gear on a non-skid bed surface that prevents equipment slippage, while an integrated stairclimber design adds stability over curbs, stairs, and uneven surfaces.

Despite its 500 lb capacity, the R9 Mighty weighs just 29.4 lbs and folds down to a slim 9.5" height for storage in a vehicle trunk, road case, or closet. Foldable side rails lock into place to secure tall loads at a full 38" unfolded height, and the R9 is compatible with RocknRoller's ecosystem of decks, shelves, bags, and accessories, letting you tailor the cart to your workflow as your gear grows.
