We do not supply any wires or hoses going from the attachment to the excavator stick.
Couplers are all over the place on the stick, so sometimes the length would be too short if we would attempt to supply a standard length and fixing that would incur extra costs.
Other times the standard length would be far too long and then the excessively dangled which was not nice for the end user.
Wires and hoses on excavator mounted attachments are inherently more prone to entanglement, so there also used to be conversations that were not fair to all parties during the time we did supply hoses and wires.
As the most fair arrangement for dealers and end users, we came up with an official policy not to supply hoses or wires in around 2010. Mounting the attachment first allows dealers and owners to measure for exact line lengths tailored to their machine.
Here is a link to some guidance how to best do that.
