All BMF single and double-beam trailers can be equipped with a frame extension that extends the load space and allows to transport longer logs or other materials. The extensions for trailers BMF16T1 and BMF18T1 are hydraulically movable. Extensions for trailers BMF11T1 and BMF13T1 are available with and without the hydraulic movement option. The maximum length of the frame extension depends on the trailer model. We recommend to add an additional bolster and set of poles to the extension.
