FAE forestry mulchers: the BL system

by Patrizia Menicucci
May - June 2021 | Back

New FAE applications for forestry forage harvesters with Bite Limiter (BL) technology.    
This is the BL4/EX/VT model, suitable for shredding logs up to 30 cm in diameter, compatible with excavators from 18 to 25 t and available with working widths of 135 and 160 cm (125 and 150 cm respectively).

The BL system provides the machine with a steel-profiled rotor that limits the depth of tool action and reduces power demand, while ensuring speed and performance. BL blades, which are particularly suitable for short and long-fibre trees, out-of-ground stumps, bushes and brushwood, are made of heat-treated forged steel, and provide additional operational savings due to their strength and the possibility of regrinding.

Other features of the shredder include a durable steel frame; a VT (Variable Torque) motor, which offers improved performance by increasing torque when needed and minimising the possibility of rotor lock-up; a belt drive (Poly Chain) that ensures high power transfer; and the Diverter valve that allows hydraulic bonnet control. Accessories available for the BL4/EX/VT include the Sonic system for optimum machine/shredder coupling; the hydraulic thumb for material handling; the deflector for safely directing the processed material; and the Spike PRO counter-blades for improved finishing of the processed material.

The new machine, which is suitable for forestry operations requiring high shredding capacity and speed, complements the other three BL 1, 2 and 3/EX products from 4 to 20 tonnes.

Since 1989, the Trentino-based company FAE has been producing heads for tractors, excavators, skid-steer loaders and special vehicles; tracked vehicles for forestry, agricultural, road and demining work, and currently has a product range that includes 90 products and 400 different models sold worldwide.
