Hand Truck, Dolly Cart Upgraded 3-in-1 Folding Heavy Duty – 330LBS Capacity Convertible with Retractable Handle Wheels for Home/Office/Warehouse

1. 6/10-Wheel Stair-Climbing System for Effortless Multi-Terrain Mobility Engineered with heavy-duty wheels and track-type mechanisms, this upgraded hand truck smoothly ascends stairs, grass, and brick surfaces—drastically minimizing user effort. Whether you opt for the 6-wheel or 10-wheel model, it ensures stable maneuverability across challenging terrains, such as carrying moving boxes up apartment stairs, transporting gardening tools across lawns, or hauling office supplies over brick pathways, making strenuous transport tasks effortless. 2. Robust Load Capacity with Durable Carbon Steel & Oxford Fabric Build Constructed with a high-strength carbon steel frame and tear-resistant 1680D Oxford fabric, the cart delivers exceptional sturdiness for long-term heavy use. It offers two capacity options: the 6-wheel model supports up to 176 lbs on flat ground and 60 lbs on stairs, while the 10-wheel version (featuring 330 lbs flat/220 lbs on stairs) reliably handles heavy items like warehouse supplies, stacked moving boxes, bulky office equipment, and grocery hauls without structural compromise. 3. Ergonomic Design for 30% Labor Savings & Prolonged Comfort Equipped with biomechanically optimized loop handles coated in non-slip silicone, it provides a secure, comfortable grip even with sweaty or gloved hands. The adjustable telescoping handle allows height customization to fit different users, reducing pushing force by 30%—a game-changer for prolonged tasks like professional moving, daily office supply transport, or large-scale grocery shopping, effectively alleviating hand and arm fatigue. 4. Patented Quick-Collapse Frame for Space-Saving Storage Featuring a patented quick-collapse system, the cart folds down to a slim 6-inch thickness in seconds, with an automatic locking mechanism preventing accidental unfolding. Its compact profile enables easy storage in car trunks, closet corners, under beds, or small office storage spaces—ideal for users with limited storage area or those who need a portable solution for on-the-go tasks like delivery runs or off-site work. 5. 36L Versatile Capacity with Thoughtful Storage Accessories Boasting a 36L storage capacity, this 3-in-1 cart adapts to diverse needs: moving, grocery shopping, gardening, and office supply transport. It comes with removable dividers to organize items and prevent shifting, a front tool mesh pocket for small accessories (e.g., tape, gloves), and side drink holders to keep beverages within reach. This all-in-one design turns it into a multi-functional workhorse for both home and professional use.
