Abstract

Mechanical coupling device 10 for traction-type excavator arms 11, 18, comprising a first main arm 11 connected at one end 12 to the structure of an excavator and at the other end 22 to a first end of a second working arm 18, the other end 23 of which is connected to a traction-type grab bucket 24 for the excavation material, also comprising jack means 14 fixed to said main arm 11 and designed to exert a thrust tending to move said working arm 18 towards the excavator, said device also comprising a lever 15 rotating about a pivot pin 17 arranged between the ends 16, 20 of said lever 15 and integral with said first main arm 11, one end 16 of said lever 15 being connected at the top to said jack means 14 and the other end 20 being connected, by means of a tie-rod 19, pivotably mounted on it, to the said second working arm 18, a thrusting action exerted by said means 14 producing a movement of said second working arm 18 towards the support structure of said traction-type excavator. <IMAGE>
