The gooseneck structure provides several advantages:
-
Greater towing stability
-
Direct ramp access for heavy equipment to drive onto the deck
-
Better weight and center-of-gravity distribution
This design is one of the main reasons lowboys are the preferred choice for heavy machinery transport.
3) Multiple Axle Configurations
Lowboy trailers offer flexible axle combinations—2, 3, 4, 5 axles or more—depending on the regional road regulations and cargo weight.
More axles mean:
-
Higher legal load capacity
-
Better stability and weight distribution
-
Increased safety when transporting ultra-heavy cargo
