Is instrumental to fast exchange of instrument. Instrument change with this arrangement is not only quicker, but also much less physical exacting, beyond classical "shake-out and hammering" pegs. Time needed to exchange with this arrangement stealing on minutes.
We produce how hydraulic, quick couplers so mechanical where's othewies need, to engineman left cabin of machine, but their unquestionable benefits is, that don't need special hydraulic circle. Next benefits is possibility their using at grip standard bucket. Bases these quick couplers is fork and self-locking hook, which on "jiging" to the bucket alone lift off and back push in. Further is need carry out "locking" against fall out of bucket. for smaller QC we use locking of hook with peg, for bigger we use sliding parts.
