Abstract

An industrial machine includes a frame having a base and a boom, an arm movably coupled to the boom, an attachment, a conduit, a first member, and a second member. The boom has a first end coupled to the base and a second end opposite the first end. The arm includes a first end and a second end. The attachment is coupled to the first end of the arm. The conduit extends from the frame to the arm. The first member is pivotably coupled to the frame and supports a first portion of the conduit as the arm moves relative to the boom. The second member is pivotably coupled between the first member and the arm, and supports a second portion of the conduit as the arm moves relative to the boom.

First claim

The invention claimed is:

1. An industrial machine comprising:
a frame including a base and a boom, the boom having a first end coupled to the base and a second end opposite the first end, the frame further including a saddle block pivotably coupled to the boom about an axis positioned between the first end and the second end of the boom;
an arm movably coupled to the boom and including a first end and a second end, the arm supported by the saddle block for movement relative to the boom;
an attachment coupled to the first end of the arm;
a conduit extending between the frame and the attachment;
a first member pivotably coupled to the saddle block and supporting a first portion of the conduit as the arm moves relative to the boom; and
a second member pivotably coupled between the first member and the arm and supporting a second portion of the conduit as the arm at least rotates relative to the boom.

2. The industrial machine of claim 1 , wherein the first member is pivotably coupled to the second member at a joint, wherein the conduit includes a flexible portion extending around the joint and defining a bend radius, wherein the bend radius of the flexible portion remains above a predetermined minimum level.

3. The industrial machine of claim 1 , further comprising a third member pivotably coupled to and extending between the first member and the second member.

4. The industrial machine of claim 1 , wherein the first member is coupled to a top surface of the saddle block and the second member is coupled between the first member and a top surface of the arm.

5. The industrial machine of claim 1 , wherein the second member pivots relative to the first member about a first axis, and wherein the second member includes a first portion and a second portion pivotably coupled to the first portion, the second portion pivoting relative to the first portion about a second axis that is not parallel to the first axis.

6. The industrial machine of claim 1 , wherein the frame supports a fluid source, wherein the conduit is a fluid conduit providing fluid communication between the fluid source and the attachment.

7. The industrial machine of claim 6 , wherein the conduit provides a lubricative fluid to a mechanical coupling on at least one of the attachment and the arm.

8. The industrial machine of claim 6 , wherein the attachment includes a bucket coupled to the first end of the arm and an actuator for actuating the bucket, wherein the conduit provides pressurized fluid from the fluid source to the actuator.
