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.

An industrial machine includes a frame supporting a boom having a first end and a second end opposite the first end, an arm movably coupled to the boom and including a first end and a second end, an attachment coupled to the first end of the arm, a conduit extending from the frame to a position adjacent the attachment, a first member coupled to the boom, and a second member spaced apart from the first member. The first member supports a portion of the conduit as the arm moves relative to the boom. The second member supports a portion of the conduit as the arm moves relative to the boom. The second member is movable relative to the first member.

A transmission having improved heat dissipation components is disclosed. The transmission includes a housing having housing walls defining an internal chamber and a rotatable input shaft extending through one of the housing walls into the internal chamber. Power transmission components are disposed in the internal chamber and rotatably driven by the input shaft. An output shaft extends through one of the housing walls from the internal chamber and is rotatably driven by the power transmission components. A lubricating fluid is disposed in the internal chamber and lubricates the power transmission components. A cooling shroud surrounds the housing and includes a cooling passageway in fluid communication with the internal chamber. The lubricating fluid flows out of the internal chamber into the cooling passageway, through the cooling passageway, and back into the internal chamber.

A dipper assembly includes a dipper, a dipper door, a closure mechanism, and one or more block assemblies. The dipper door is pivotally mounted to the dipper, and has a closed position in which the dipper door covers the dipper bottom. The closure mechanism has a locked position and an unlocked position, and is coupled to the dipper back and the dipper door. In the locked position, the closure mechanism holds the dipper door in the closed position. In the unlocked position, the closure mechanism allows the dipper door to swing away from the closed position. The block assemblies are coupled to the dipper back and limit a rotation of the side link plate to a pre-defined angle that corresponds to the closed position.

Dipper door assembly

A dipper assembly includes a dipper, a dipper door, and a closure mechanism. The dipper door is coupled to the dipper, and has a closed position in which the dipper door covers the dipper bottom. The closure mechanism has a first position and a second position. In the first position the closure mechanism is configured to permit movement of the dipper door away from the dipper bottom. In the second position, the closure mechanism is configured to retain the dipper door in the closed position. The closure mechanism includes a link having a first leg and a second leg, one or more side link plates coupled to the link and to the dipper back, and a closure mechanism pin assembly configured to adjust the position of the link relative to the dipper door.
