The specifications below are for a 4-axle semi low loader with ramps, both single and double extendible. As you expect from us, you can also get a 4-axle semi low loader according to your specifications.  Consider for instance wheel wells, a crane arm recess or a triple-extendible trailer. We will be happy to help you configure your own 4-axle semi low loader. You can contact one of our employees for this at any time with no obligation.
