<p>In the operation of a construction machine, such as a wheel loader, it is essential to provide load distribution capabilities for improved strength characteristics in the components. Additionally, high visibility is required for an operator to view a work implement during normal operation or coupling. The present invention includes a hydraulic coupler (180) utilizing a pair of separate coupler assemblies (184,188) which are connected at opposing ends (197,198) of an upper and lower coupler pin boss (162,86) at a pair of pin joints (260,264) including a pair of pins (230,238) to define a spatial relationship therebetween. The pins (230,238) each have a cylindrical central portion (242) and rectangular shaped end portions (246,250) which are fixed within rectangular shaped pin mounting openings (207,208) in first and second end portions (200,204) of the coupler assemblies (184,188). The separation of the coupler assemblies (184,188) provides enhanced visibility for an operator. The utilization of the pins (230,238) as structural members distributes loading in a substantially straight path from the work implement (14) to the machine (11) decreasing the load burden on components, such as the hydraulic coupler (180). <IMAGE></p> |
