Design of excavator with a longer boom arm is base on lever principle, under this principle, one point we conclude is that a long boom arm/stick excavator should equipped with a smaller capacity bucket compare with standard bucket capacity. and counterweight is needed for some cases. another point we can have is that boom arm length is not the longer the better, longer boom arm mean sacrifice of bucket capacity. we conclude below long reach boom arm data from our calculation and experience.
