BMF forestry cranes are capable of lifting heavy log loads on and off the trailers, therefore it is essential for the trailer and crane to be stable. BMF trailers can be equipped with two types of support legs that ensure additional stability during lifting. A-leg is a telescopic outrigger leg that is compact and fast-moving. FD or flap-down leg provides maximum stability for challenging conditions. Cylinders of both type of support legs are securely protected.
