Configuration of the new mini excavator YFE18MAX:
1: The advantages of the hydraulically controlled walking foot valve are: the control stroke of the walking push rod is smaller, so the leg space will be larger, and the flow output of the hydraulic control is smoother and more accurate. When the excavator goes uphill or downhill, it can achieve smooth climbing and downhill through fine-tuning.
2: The bottom plate under the feet is changed to a flat one, which increases the space under the feet and improves the operating comfort of the driver.
3: 18MAX is equipped with a Kubota engine and a standard three-way load-sensitive hydraulic pump with a flow rate of 30 liters per minute. Compared with the 18U three-way pump, the flow rate is five liters per minute higher. The action will be more coordinated, the compound action will be softer, and it can match large-flow hydraulic accessories
4: The swing motor of 18MAX is equipped with a two-way overflow valve block as standard. After the valve block is installed, it is a protection for the instantaneous back pressure of the swing motor to be too high. The standard models without valve blocks generally have broken shafts and oil leakage at the shaft ends of the rotating motor. After the valve block is installed, the probability of the above two problems is reduced, the user experience is enhanced, and the failure rate is reduced.
5: The entire 18MAX series is equipped with Taifeng load-sensitive multi-way valves as standard, which have more precise action directions and support 3-4 compound action linkages, increasing work efficiency by 30%
6: The entire series is equipped with hydraulically controlled walking foot valves as standard. The advantages are: the travel stroke of the walking push rod is smaller, so the leg space will be larger, and the flow output of the hydraulic control is smoother and more accurate. When the excavator goes uphill or downhill, it can achieve smooth climbing and descent through fine-tuning.
7: The entire MAX series is equipped with a single-speed hidden plunger walking motor as standard.
The characteristics are that the volumetric efficiency and service life of the plunger travel motor are 3-5 times that of the ordinary exposed travel motor, and the output torque of the plunger travel motor can be increased by 30% compared with the exposed travel motor, and the escape ability is stronger, and it can cope with the harsher driving conditions. Secondly, the exposed travel motor is exposed outside the chassis, while the single-speed plunger travel motor is embedded inside the chassis, which can prevent the excavator from being damaged by collisions with debris when it is traveling.
8: The hydraulic oil tank is upgraded from the previous horizontal structure to a vertical structure, which effectively prevents the excavator from tilting too much during climbing or downhill operations, causing the oil to be lower than the oil inlet, resulting in insufficient oil suction and damage to the gear pump.
