Compared with the previous generation, fuel consumption is reduced by 6% and efficiency is increased by 10%. The diameter of the rotary bearing ball is 20% larger than that of the previous generation, and the raceway diameter is increased, so the bearing capacity is increased by 15%. Adopt the imported shock absorber with silicone oil seals, improves the rigidity of the cab floor, and reduces the shaking of cab and the operator’s fatigue.
