This multi-functional cart has a load-bearing capacity of up to 3,000 pounds. It can transport multiple sheets of drywall, plywood, marble slabs, or glass in a single trip, reducing transportation time by 60% and improving efficiency for contractors or DIY enthusiasts. Constructed from sturdy alloy steel, it easily bears heavy loads. The protective coating on its surface provides rust resistance, allowing it to maintain good condition even when used on construction sites or outdoors, ensuring strong durability. The cart is equipped with four swivel casters (all with locking functions to ensure transportation safety), enabling smooth movement in any direction. Its open-angle design facilitates quick loading of drywall, and the inclined support structure can secure the boards to prevent slipping during transportation. Assembly is simple, no complex screws or tools are required. It can be used immediately after installing the casters and handle. After work, it can be easily disassembled and stored in a trunk or tool room, saving space and making it suitable for busy mobile workers. In addition, the cart has a wide range of applications: it can transport items from drywall to steel beams, and can easily meet heavy-load handling needs in scenarios such as construction sites, warehouses, and households.
