Abstract

Attachment assemblies for industrial material handling equipment are shown and disclosed. In some embodiments, the attachment assembly includes a carriage assembly having a carriage and a linear actuator fixedly attached to the carriage. The carriage is mountable to industrial material handling equipment. The attachment assembly additionally includes a frame assembly slidably connected to the carriage. The attachment assembly further includes a faceplate assembly fixedly attached to the frame assembly. The faceplate assembly is configured to receive one or more support members for supporting a load. The faceplate assembly includes one or more load cells configured to measure horizontal and vertical forces applied to the one or more support members. The linear actuator slides the frame assembly laterally relative to the carriage assembly.

Claims (22)

1 . An attachment assembly, comprising:

a carriage assembly having a carriage and a linear actuator fixedly attached to the carriage, the carriage being mountable to industrial material handling equipment;

a frame assembly slidably connected to the carriage, the frame assembly having upper and lower transverse frame members and end vertical frame members connecting the upper and lower transverse frame members in a spaced relationship to define a frame central cavity therebetween, wherein the linear actuator is disposed within the frame central cavity such that the ends of the piston rods contact the end vertical frame members allowing the linear actuator to slide the frame assembly laterally relative to the carriage assembly; and

a faceplate assembly fixedly attached to the frame assembly, the faceplate assembly is configured to receive one or more support members for supporting a load, wherein the faceplate assembly includes one or more load cells configured to measure horizontal and vertical forces applied to the one or more support members and includes upper and lower transverse faceplate members and end vertical faceplate members connecting the upper and lower transverse faceplate members in a spaced relationship to define a faceplate central cavity therebetween.

2 . The attachment assembly of claim 1 , wherein the carriage includes an upwardly protruding portion and the frame assembly includes a downward hook portion having a groove, wherein the upwardly protruding portion is received in the groove to allow the frame assembly to slide laterally relative to the carriage assembly.

3 . The attachment assembly of claim 2 , wherein the upwardly protruding portion includes a cavity for receiving a portion of the industrial material handling equipment such that, when the portion of the industrial material handling equipment is received in the cavity, the upwardly protruding portion is disposed between the downward hook portion and the portion of the industrial material handling equipment.

4 . The attachment assembly of claim 2 , wherein the carriage includes only a transverse carriage member having the upwardly protruding portion.

5 . The attachment assembly of claim 2 , wherein the carriage includes upper and lower transverse carriage members and end vertical carriage members connecting the upper and lower transverse carriage members in a spaced relationship to define a carriage central cavity therebetween.

6 . The attachment assembly of claim 5 , wherein the upper transverse carriage member includes the upwardly protruding portion.

7 . The attachment assembly of claim 6 , wherein the carriage includes a tab sized to be received in a notch of the industrial material handling equipment.

8 . The attachment assembly of claim 1 , wherein the linear actuator includes a body fixedly attached to the carriage and longitudinally opposed piston rods slidably received in the body, each of the piston rods having an end.

9 . The attachment assembly of claim 1 , wherein the faceplate assembly further includes a fork positioner disposed within faceplate central cavity, the fork positioner configured to selectively move a pair of forks toward or away from each other.

10 . The attachment assembly of claim 9 , wherein the faceplate assembly includes a center tie bar that spans between the upper and lower transverse faceplate members across the faceplate central cavity.

11 . The attachment assembly of claim 1 , wherein the faceplate assembly includes at least one faceplate hole and the frame assembly includes at least one frame hole that corresponds with the at least one faceplate hole, wherein the at least one load cell of the one or more load cells is contained within at least one housing, and wherein the at least one housing is received in the at least one faceplate hole and the at least one frame hole.

12 . The attachment assembly of claim 11 , wherein the frame assembly includes at least one fastener to secure the at least one housing to the at least one faceplate hole and the at least one frame hole and to secure the face plate assembly to the frame assembly.

13 . The attachment assembly of claim 1 , wherein the one or more load cells each includes one or more first strain gauges and one or more second strain gauges that are perpendicular to the one or more first strain gauges.

14 . An attachment assembly, comprising:

a carriage assembly having a carriage and a linear actuator fixedly attached to the carriage, wherein the carriage includes only a transverse carriage member having an upwardly protruding portion;

a frame assembly slidably connected to the carriage, wherein the frame assembly includes a downward hook portion having a groove, wherein the upwardly protruding portion is received in the groove to allow the frame assembly to slide laterally relative to the carriage assembly, wherein the upwardly protruding portion includes a cavity for receiving a vertically projecting portion of the industrial material handling equipment such that, when the vertically projecting portion of the industrial material handling equipment is received in the cavity, the upwardly protruding portion is disposed between the downward hook portion and the vertically projecting portion of the industrial material handling equipment; and

a faceplate assembly fixedly attached to the frame assembly, the faceplate assembly is configured to receive one or more support members for supporting a load, wherein the faceplate assembly includes one or more load cells configured to measure horizontal and vertical forces applied to the one or more support members, and wherein the linear actuator slides the frame assembly laterally relative to the carriage assembly.

15 . The attachment assembly of claim 14 , further comprising a tab that is centrally disposed on and attached to the transverse carriage member, the tab being sized to be received in a centrally disposed notch of the vertically projecting portion of the industrial material handling equipment.

16 . The attachment assembly of claim 14 , wherein the upwardly protruding portion is J-shaped.
