Extended reach crowd control for a shovel
First Claim
1. An assembly for a shovel, the assembly comprising:
- a dipper handle including a first end operable to support a dipper, the dipper handle having an end surface opposite the first end, the end surface including a first mounting feature and a second mounting feature; and
a bracket having a first surface engageable against the end surface and a second surface opposite the first surface, the bracket including a first lifting opening, a first end, and a second end, the first lifting opening being coupled to the second surface, the first end defining a guide surface, the second end including a second lifting opening, the bracket being selectively connected to one of the first mounting feature and the second mounting feature, the bracket being selectively positioned in a first orientation relative to the dipper handle and a second orientation relative to the dipper handle.

Abstract
An industrial machine and a method of controlling an industrial machine, the industrial machine including a dipper supported by a dipper handle. The method may include determining an operating phase of the industrial machine, in a first operating phase of the industrial machine, limiting, with at least one controller, a reach of the dipper handle, and in a second operating phase of the industrial machine, enabling, with the at least one controller, an extended reach of the dipper handle greater than the reach in the first operating phase. The industrial machine may include at least one controller configured to determine an operating phase of the industrial machine, in a first operating phase of the industrial machine, limit a reach of the dipper handle, and, in a second operating phase of the industrial machine, enable an extended reach of the dipper handle greater than the reach in the first operating phase.

8. A method for installing a dipper handle on a boom of a shovel, the dipper handle including a pair of parallel arms, each arm having a first end and a second end, each second end including an end surface having a periphery, the method comprising:
-
coupling a bracket to an end surface of each arm in a mounting position, each bracket including a lifting opening and a guide surface positioned in an orientation relative to the dipper handle; while partially supporting the dipper handle by the lifting opening of each bracket, moving the dipper handle into an installation position; and moving one of the dipper handle and the boom in order to couple the dipper handle to the boom, as the dipper handle and the boom move toward one another, the guide surface of the bracket engaging the boom to align the dipper handle relative to the boom. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A dipper handle for a shovel, the dipper handle being operable to support a dipper, the handle comprising:
-
a first end having a pin connection operable to support the dipper; a second end opposite the first end and defining an end surface, a distance between the first end and the second end defining a handle length; and a rack extending partially between the first end and the second end, the rack including a termination end proximate the first end and a greenhorn defining an end point of a usable portion of the rack, the greenhorn being positioned proximate the second end, the usable portion of the rack having a length at least 65% of the handle length. - View Dependent Claims (17, 18, 19, 20, 21)
