The manual tank dolly is a lightweight and highly flexible short-distance handling device for factory use. It operates entirely manually via push-pull motion, requiring no power supply or fuel, and features a low operational threshold along with a wide range of applications. Constructed with a thickened high-strength steel structure, it offers stable load-bearing capacity, excellent durability, and anti-deformation properties. Equipped with wear-resistant and silent universal wheels, it operates smoothly and rotates flexibly, making it perfectly suitable for narrow aisles and limited working spaces in workshops and warehouses.
