The distance in between the ears on the attachment isn’t as crucial as long as it is wide enough for the coupler to drop down and grab the pins. Manual couplers tend to be specific to the excavator and pick up the OEM pin dimensions. However, we can still provide loose pins in case the attachment ever has to be manually pinned on another machine, or the coupler has to come off the machine to be fixed etc. The pins can be welded/fixed in order to prevent more movement/slop from having loose pins. Quick couplers make it slightly easier on the attachment side for building a mount. What does this mean on the attachment side? These couplers require the operator to get out of the machine but are a lot faster and easier than manually knocking out the pins of one bucket to put on another. The operator would pick the attachment using the front on, before getting out of the machine to open the coupler and lock in the rear pin. Manual Quick CouplersĪ manual coupler is manually opened and closed by the operator in order to lock the attachment in place securely. Quick couplers are an attachment that is fitted to the excavator to allow the operator to easily change between buckets and other attachments. From The Attachment Company this would require a short lead time in order to build the attachment mount to suit the OEM pin dimensions. This would mean that it would be a tight fit around the machine and the pin centers would be what the manufacturer requires to enable full movement of the attachment. For a pinned attachment for a machine without a quick coupler, we would build the attachment to these dimensions to allow for a good fit to the machine.
