Flat Top Trailers for Difficult Loads Our versatile flat top trailers can be used for carrying hard-to-handle loads, including vehicles, plant and machinery. As they don’t have sides they can also be used on a worksite as a stable work space. Flat top trailers can be fitted with a hydraulic tipping mechanism, so there is no need to carry heavy ramps. https://www.basictrailers.com.au/trailers.php?category=flat%20top%20trailers
