When procuring a Lowboy Loader, the most critical factor is the Load Capacity, typically ranging from 20 to over 100 tons. You must verify the Gooseneck Type (Fixed, Mechanical Detachable, or Hydraulic Detachable), as Hydraulic Detachable Goosenecks (RGN) are preferred for heavy machinery due to their ease of front-loading. Additionally, inspect the Deck Length and Height; a low-profile deck (usually 18-24 inches high) is essential for transporting tall equipment under bridges. Ensure the use of High-Tensile Steel (e.g., Q345B or T700) to prevent structural deformation under extreme stress.
