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. The extensions for trailers BMF16T1 and BMF18T1 are hydraulically movable. Extensions for trailers BMF11T1 and BMF13T1 are available with hydraulic or mechanical movement option. The maximum length of the extension depends on the trailer model. We recommend to add an additional bolster and set of poles to the extension.
