AUTO LOCK QUICK COUPLER FOR EXCAVATORS
An auto lock quick coupler for earthmoving implements using positive mechanical locking means. A hydraulic actuator locks and unlock the mounting bars of the attachment. Kinematics of the linkages keep the attachment safe during a hydraulic failure. 1~> '4 / 11/ 'N 1~717/ .5 -> K ~. .~;/ ti N,, /72! / ~wK / >5 N>' // N '4 I ~ //c-> .- NNJ 1K' VK;~;>;71tt 773 12 N y~ 7 / ij~ 1,7 'Nv k it 12' (5 1 -7 '<"5- ____________________________________________________________ '-7 <5 ~Q't'9$' 'i/~(,/ / / $7$m--4<-> <'<5 N- vs,- ~ -N--?
