Abstract
A method of remodeling a control section of a backhoe comprising adding a relay unit including relay rotary sleeve shafts and rotary shafts rigidly attached to a carrier base to extend in two parallel rows, and operatively connecting the rotary sleeve shafts and rotary shafts selectively to drive rods which are pushed or pulled by an oscillation in one direction of one of the hand levers, respectively, and to driven rods operatively connected to those of the valves which should be actuated by the drive rods, respectively.
Claims1
A method of remodeling a control section of a backhoe by which a basic interlocking structure (A) operatively connecting, by a rod interlocking mechanism, two hand levers (8a,8b) oscillatable crosswise to four backhoe implement control valves (V4-V7) selectively and simultaneously, is remodeled into a modified interlocking structure (B, C) providing an interlocking relationship different from said particular interlocking relationship, said method comprising adding a relay unit (23) including relay rotary sleeve shafts and rotary shafts (18a, 18b, 20) rigidly attached to a carrier base (22) to extend in two parallel rows, and operatively connecting said rotary sleeve shafts and rotary shafts (18a, 18b, 20) selectively to drive rods (24a-24e) which are pushed or pulled by an oscillation in one direction of one of said hand levers (8a, 8b), respectively, and to driven rods (25a-25d) operatively connected to those of said valves (V4-V7) which should be actuated by said drive rods (24a-24e), respectively.
