I’m working with several European Equipment manufactures to develop tree cutting technology on excavators. (See website: I just purchased a EGO self propelled lawn mower. I was really impressed with the proformance of this Equipment. It made me wonder if this technology could help us solve some of the challenges we are having with our grapple saw project. Currently we are using a hydraulic motor to power our saw, but this has many limitations for this application. Our grapple saw is operating on the end of a tiltrotator. This is a device that is used to greatly increase the range of motion of an excavator. Basically it gives an excavator the same range of motion as a human wrist and arm, but with much more strength. However the limitation is getting hydraulic hoses thru a continuious rotating rotator. That is where a electric cordless saw could help. I looked into the EGO chain saw and other cordless saws available. They are too small for our application. However a typical mid sized gas power chain saw proformance is all we need. Something 5 to 10 horsepower. Given the proformance of the EGO lawn mower, I think this might be possible. We are looking for someone to helps us explore this possible application of cordless technology.
Our rotator offers us one hydraulic circuit and 6 electrical signal wires. We use the hydraulic circuit to power all of mechanical movements like grapple, bar movements and oil pump for saw. Signal wires might be big enough to provide recharge power to batteries, but do not offer potential of running direct power from excavator to electric motor for saw. That is where batteries would come in. They would offer large amount of power for short burst close too saw. Grapple saw assembly already weighs more then 500 pounds, so even the addition of 4 EGO 56v batteries would not even be a significant weight increase. Our grapple saw idea has significant market appeal for tree service, utility and excavation companies. Would EGO be interested in working with us to power our saw? Are their independent engineers in the EGO community that might be interested in working with us. Are their people within EGO community who could recommend persons who could help us? We have the saw part of our product All developed, we just need the power source for the saw. Could the EGO batteries and charging system work for this appliation?
