  • Patent number: 6360459
    Abstract: A tiltable bucket assembly includes a bucket and an interface member. The bucket has a front loading portion, a rear connecting portion with a front surface adjacent the front loading portion and a rear surface opposite therefrom, and a pair of spaced guide members connected to the rear surface. The bucket defines a substantially enclosed chamber that extends from the front surface and terminates within the front loading portion. The interface member is rotatably mounted with the bucket. The interface member has opposed side portions supported within the guide members. A hydraulic cylinder is located within the chamber and has a rod end portion connected to the bucket and a head end portion connected to the interface member. The hydraulic cylinder is adapted to provide rotational movement of the bucket about the interface member upon actuation.

  • Patent number: 6227792
    Abstract: 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 utilizing a pair of separate coupler assemblies which are connected at opposing ends of an upper and lower coupler pin boss at a pair of pin joints including a pair of pins to define a spatial relationship therebetween. The pins each have a cylindrical central portion and rectangular shaped end portions which are fixed within rectangular shaped pin mounting openings in first and second end portions of the coupler assemblies. The separation of the coupler assemblies provides enhanced visibility for an operator.

  • Patent number: 5535533
    Abstract: The lift arms and linkage arrangement for the bucket of a loading machine includes first and second spaced apart lift arm assemblies and first and second spaced apart linkage assemblies associated with respective lift arm assemblies. The first and second lift arm assemblies diverge with respect to the centerline of the machine while the first and second linkage assemblies are parallel to the centerline of the machine. The first and second lift arm assemblies are closer to each other at the machine end than at the bucket end. This provides greater visibility of the corners of the bucket for the machine operator and more precise positioning of the bucket by the operator.
