I.Features&Benifits
1. YTO LR4A3Z-22 turbo engine or CUMMINS 4BTA3.9-C80, YJ280 type torque converter and ZL20 gearbox, ZL25 heavier type driving axles, ratio decreased, traction increased 20%, more powerful and work more efficiently.
2. Air over hydraulic brake, 15/70-18 tyre , automatic leveling function.
3. Strengthed frame, more robust, tires have high adhesion.
4. Bucket motherboard with wear-resistant 400 steel plate made by Wugang, very durable;
5. Overall length ≤5.2 meters, the whole width ≤1.8 meters, Overall height ≤1.9 meters, more narrower, lower and shorter, suitable for ultra-low, ultra-narrow aisle works.
6. Standard with exhaust purification device ( imported three way catalytic converter; optional wet brake axle)
