Quality identification of excavators
Because the factory is concentrated in Jining City, a spare parts factory at the same time to a number of excavator factory supply, the similar accessories lead to the appearance of the same, from the appearance is difficult to judge the excavator is good or bad, you can from the following aspects to the excavator factory query:
1, hydraulic pump: cast iron pump can resist the vibration brought by the strong power of the engine, and better transform the power source. The impact resistance of cast aluminum pump is low, and the power conversion is poor.
2, hydraulic cylinder: high quality high-pressure heavy duty hydraulic cylinder adopts high precision quenching process, can withstand better pressure and greater full load. The standard hydraulic cylinder is not quenched, the thickness increases, and it is easy to deform.
3, support shaft: it is not easy to bend after quenching, ordinary support shaft thickening, different hearts, can also rotate without quenching
.
4, dodging plate: 90 degree dodging plate is designed to push the earth vertically outward, do not push the earth backwards. The common 45 degree dodging board is easy to overturn and affect walking.
5, boom: enhanced boom, not easy to break.
6, chassis: increase the pull rod design, so that the track and the wheel more closely fit, enhance the driving force.
7. Safety protection: Improve operation safety.
