Abstract
A fork assembly can include multiple forks configured to surround a load. Multiple attachments can be made on the forks to couple to straps for support a load. The fork assembly can further include multiple fork extensions having end attachments to couple to straps for pulling on the load. Alternatively, the fork assembly can include multiple fork lifters having blades rotatable between a non-lift position and a lift position. The fork extensions can also have blades rotatable between a non-pullable position and a pullable position. The blade rotation can be performed by a remote rotate mechanism by an operator operating the fork assembly.

A fork assembly for attaching to a forklift vehicle for lifting a load, the fork assembly comprising
- one or more forks configured to be coupled to the forklift vehicle,
- wherein a fork of the one or more forks comprises a fork beam configured to be extended away from the forklift vehicle,
- one or more lifter assemblies,
- wherein at least a lifter assembly of the one or more lifter assemblies is configured to be coupled to the fork of the one or more forks,
- one or more rotate mechanisms,
- wherein at least a rotate mechanism of the one or more rotate mechanisms is configured to be coupled between the fork beam of the fork and a blade of the at least a lifter assembly,
- wherein the at least a rotate mechanism is configured to rotate the blade relative to the fork beam by moving the fork assembly,
- wherein the at least a rotate mechanism is configured to rotate the blade relative to the fork beam between a first position and a second position,
- wherein in the first position, the blade is disposed under the load,
- wherein in the second position, the blade is disposed outside the load.
A fork assembly for attaching to a forklift vehicle for lifting a load, the fork assembly comprising
- one or more forks configured to be coupled to the forklift vehicle,
- wherein a fork of the one or more forks comprises a fork beam configured to be extended away from the forklift vehicle,
- one or more lifter assemblies,
- wherein at least a lifter assembly of the one or more lifter assemblies is configured to be coupled to the fork of the one or more forks,
- one or more first rotate mechanisms,
- wherein at least a first rotate mechanism of the one or more first rotate mechanisms is configured to be coupled between the fork beam of the fork and a first blade of the at least a lifter assembly,
- wherein the at least a first rotate mechanism is configured to rotate the first blade relative to the fork beam by moving the fork assembly in upward and downward directions,
- wherein the at least a first rotate mechanism is configured to rotate the first blade relative to the fork beam between a first position and a second position,
- wherein in the first position, the first blade is disposed under the load,
- wherein in the second position, the first blade is disposed outside the load,
- one or more fork extensions,
- wherein at least a fork extension of the one or more fork extensions is configured to be slidable along the fork beam of the fork for extending a length of the fork beam,
- wherein the at least a fork extension comprises a second blade coupled to an end of the at least a fork extension,
- wherein the at least a fork extension comprises a second rotate mechanism coupled between an end of the fork beam and the second blade.
- wherein the at least a second rotate mechanism is configured to rotate the second blade around an axis of rotation parallel to the at least a fork extension by moving the fork assembly in forward and backward directions,
- wherein the at least a second rotate mechanism is configured to rotate the second blade around the axis of rotation between a third position and a fourth position,
- wherein in the third position, the second blade points toward the load,
- wherein in the fourth position, the second blade points away from the load or parallel to the load.
A fork assembly for attaching to a forklift vehicle for lifting a load, the fork assembly comprising
- one or more forks configured to be coupled to the forklift vehicle,
- wherein a fork of the one or more forks comprises a fork beam configured to be extended away from the forklift vehicle,
- wherein the fork beam comprises one or more first cable attachments for attaching first cables configured to support the load for lifting,
- one or more fork extensions,
- wherein at least a fork extension of the one or more fork extensions is configured to be slidable along the fork beam of the fork for extending a length of the fork beam,
- wherein the at least a fork extension comprises a second cable attachment coupled to an end of the fork extension,
- wherein the second attachment is configured for attaching a second cable around the load configured to for pulling the load.
