Excavator, excavator boom, stick object coupler receiver for the same and method of using the same

摘要

An excavation machine and a coupler system for use on the excavation machine to allow a universal adaptor for the attachment of skid steer attachments to be joined directly to a working end of a main lifting boom of the excavation machine, the coupler system including a first coupler body having a first rearward portion and a first forward portion, the first rearward portion being connectable to the working end of the lifting boom, the first coupler body having a first mating arrangement, the coupler system further including a second coupler body that is secured or securable relative to the universal adaptor, the second coupler body having a second mating arrangement that is selectively securable to the first mating arrangement to selectively secure the universal adaptor directly relative to the working end of the lifting boom of the excavation machine thereby allowing the excavation machine to use both skid steer attachments such as an associated skid steer bucket attachment joined directly relative to the working end of the lifting boom and a traditional dipper stick.
