With the term “slow axles” we define those axles which can equip working vehicles, i.e. all vehicles used in agricultural field (harvesters or sprayers) or building sites (dumpers and mixers) with permitted load ranging from 1, 5 up to 6, 5 tons with a speed not higher than 50/60 km/h. All these axles are available both in rigid (M4P-A31.10, M4P-21.10, M4P-25.10,M4P-30.10, M4P-31.10) and steering versions (M4P-A31.20,M4P-21.20,M4P-25.20,M4P-30.20, M4P-31.20). For higher reduction ratios (maximum i=1:31) the axle is supplied coupled to a gearbox with grinded-tooth-profile gears, able to ensure low noise levels and for this reason suitable for electric applications. Steering axles are provided with steering drive kits, made by a double effect cylinder, axial and radial joints. Each axle can be equipped with an input parking brake, that could be disc or drum brakes and service brakes suitable for required brake capacity, in disc, drum or oil-immersed versions for heavier usages. For all versions a 100% differential lock system controlled by a lever or interlocked by a hydraulic, pneumatic or electric system is available. A self-locking system with a high locking coefficient up to 60 % is also available.
