Structure of mechanism |
| Function |
Version Anglaise : An operative arm of an earth moving machine, in particular of an excavator, has a bucket, which is rotatable about an axis under this action of a jack. Between the rod of the jack and the bucket, a transmission is interposed provided with a first and with a second lever, which are mutually hinged about an intermediate axis parallel to the axis of rotation of the bucket.
The first and second lever have opposite ends, one hinged to the rod of the jack and the other one to the bucket. The transmission is further provided with a lever adjustable length enabling to vary the torque transmitted by the jack to the bucket and hinged about the aforesaid intermediate axis and the axis of rotation of the bucket. |
| Comment |
The path of the both jack is determined with the angle of the bucket rotation that we need to close completely it.
