Appl. No.:

10/319142

Inventors:

Gary E. Volle - Wauwatosa WI
Ross C. Smith - Shorewood WI
Stephen J. McCormick - Shorewood WI

Assignee:

MHE Technologies, Inc. - Wilmington DE

International Classification:

B66D 136

US Classification:

254285, 254338, 254293, 212274

Abstract:

A lifting arrangement for overhead traveling cranes. The lifting arrangement includes two single reeved drums that are reeved together to provide true vertical lift of a load. The lifting arrangement allows for equalization of full up and full down rope fleet angles through utilization of axially staggered dual drums and/or a bottom block with two separate sheave nests. The lifting arrangement may utilize commercially available components to reduce the overall cost of the crane when compared with other powerhouse crane designs.

254342, 254344, 254345, 74801

Abstract:

The invention relates to a hoist apparatus including at least one of a three-part double reeved bottom block that has the same height profile as a two-part bottom block and the same lifting capacity as a three-part bottom block that includes an integral equalizer sheave nest, a device for limiting the rotation of a hoist drum beyond a desired position, a hybrid gear box adapted for use on two different categories and/or types of hoist apparatuses through the use of an adapter plate that permits coupling of the gearbox to the hoist drum of the hoist apparatus in a plurality of configurations and an external ring gear that results in a second output torque and speed of the gearbox, a self-lubricating load braking assembly having lubrication inlet holes and lubrication outlet holes for pumping lubrication into and out of the load brake assembly, a gearbox for use on the hoist apparatus including a two-stage high gear ratio gear set and a load brake assembly, a controller configured to acquire operational data representative of the hoist apparatus and generate an output indicative of a remaining useful life of the hoist apparatus, and an inverter controller configured to control verify load integrity and prevent possible load loss without the use of a load brake assembly and/or an encoder or similar feedback device.

International Classification:

C21D009/32

US Classification:

148573000, 266104000

Abstract:

A method and apparatus for case hardening a work piece by inductive heating is disclosed. In one embodiment, the apparatus includes a ring of conductive material having an inner diameter, an outer diameter, and opposing planar sides. In one embodiment, dielectric material fixed to the planar sides of the ring prevents the electrical power passing through the conductive material from short circuiting. In another embodiment of the invention, a plurality of conductive teeth extend radially from at least one of the inner diameter and the outer diameter of the ring, wherein a valley having a vertex is formed between adjacent conductive teeth, and conductive material is removed from the ring proximal the vertex to prevent overheating gear teeth of the work piece being hardened. In yet another embodiment of the invention, a plurality of conductive teeth extending radially from at least one of the inner diameter and the outer diameter and at least one slot extending radially toward a tip of one of the teeth is formed in the conductive material to force the electric current closer to the teeth being hardened.

Assignee:

Deutz-Allis Corporation - Milwaukee WI

International Classification:

F16H 5702

US Classification:

74767

Abstract:

A single axis multi-speed planetary transmission of the epicyclic type is provided in which a single rotating housing encloses and carries three epicyclic gear sets. Hollow end portions of the rotating housing are carried on a stationary housing by bearings and quill shafts extend from the end portions and are connected to brakes carried on the stationary housing. Two fluid operated clutches are provided within the rotating housing to selectively interconnect certain of the components of the epicyclic gear sets and together with the two brakes provide controls to effect one reverse and five forward speeds. The output shaft is a quill shaft and the input shaft extends through the transmission, and through the output shaft, to provide a power takeoff shaft at the output end of the transmission.

Assignee:

Harnischfeger Corporation - Brookfield WI

International Classification:

B65H 7528

US Classification:

242117

Abstract:

A clamping mechanism for releaseably securing the end of a rope to a winch drum. The winch drum includes first and second walls that are spaced apart in facing relation to each other to define therebetween a rope end receiving space having open front and rear ends. One of the walls in the space is contactable by the rope end that is to be secured to said winch drum. A clamping wedge member has an axis, a drum side contactable with the other of the winch drum walls, a rope side contactable with the rope end, and a drive end to which a first axial force can be applied. Application of the first axial force moves the wedge member axially into the space and causes a first lateral clamping force be applied, initially clamping the rope end against the one wall. A transverse thrust device is mounted on the drum for applying a transverse force against the drum side of the wedge member transversely of the wedge axis to cause a second lateral clamping force to be exerted against the rope end.

Inventors:

Stephen J. McCormick - Shorewood WI

Assignee:

Harnischfeger Corporation - Brookfield WI

International Classification:

F16D 6300

US Classification:

188 821

Abstract:

The invention involves a hoist for raising and lower loads. The hoist includes a drive motor, gearing, a load brake and a cable-winding drum. The drum has an end with a splined annular member slidably engaging a similar splined annular member of a drum-concentric friction plate. The friction plate directly drives the drum during load raising and directly brakes the drum during load lowering. Because of the direct mechanical coupling between the drum and the friction plate, a failure in the gearing does not impair the ability of the friction plate to brake the load. Further details of the invention are set forth in the specification.
