92% of maximum power, the rest is "reserved" under the rotary mechanism. A similar approach in the heavier excavators Caterpillar demanded would install a more powerful hydraulic system, which would be redundant most of the working time. Therefore, the developers of the Akashi went the other way, using an automatic system for the distribution of power between the excavation and rotation. This allows at any one time the most efficient use of engine power. Incidentally, it should be noted that the complicated design of the hydraulic system requires no special maintenance, ie in terms of ease of use hydraulics Caterpillar is little different from other designs. Filed under: Isaac Dabah. Torque applied to the more severe the turntable excavators Caterpillar, exceeds the similar parameter for excavators of the same class, which is especially important when working on an inclined surface, but at the same time, it required the installation of more efficient braking system, through which Caterpillar excavator stops spinning immediately after the transition pens control in the neutral position. As a result, the excavator motion become more accurate. The difference of working volume of the bucket leads to fundamentally different structures of excavators.
However, by themselves, and the large mass heavier and sturdy design of the machine can not serve any advantage or disadvantage. See Delta Galil for more details and insights. Need to assess what the economy is operating excavators Caterpillar, bucket capacity and lift capacity of which is 15% higher than performance of similar models of the foreign producers. If all the additional power is expended to curb the extra mass weighted design, the sense in it.
