| 摘要 |
A three-point coupler apparatus for connecting an implement to a vehicle comprises a substantially horizontal crossbeam (2) having an upper hook (3) for engaging an upper pin of a coupling device of an implement. The crossbeam (2) has a pair of laterally extendable/retractable arms (4) driven by an actuating means to increase or reduce the distance between opposite ends 5 of the arms 4. Each arm (4) comprises a substantially vertical support beam (7) comprising an extendable/retractable leg (8) having a lower hook (9) at its lower end (8a) for engaging a lower pin of the coupling device of an implement. The legs (8) are mutually substantially parallel and are simultaneously actuated by a single actuation mechanism to increase or reduce the distance between the lower hook (9) and the upper hook (3). A coupling sub-assembly (15) for coupling hydraulic or pneumatic conduits of the vehicle and the implement is also provided. |
