Abstract
A high visibility push-pull handler configured to be mounted on a lift truck. The handler comprising a frame assembly, a pantograph mechanism coupled to the frame assembly, and a faceplate assembly coupled to the pantograph mechanism. The hander is configured with a view window extending through the handler, the view window not obstructed by parts of the handler when the handler is in any normal operating configuration, including a fully extended configuration, a fully retracted configuration, and any configuration in between the full extended and fully retracted positions.
Claims11
A high visibility push-pull handler configured to be mounted on a lift truck comprising:
- a frame assembly;
- a pantograph mechanism coupled to the frame assembly;
- a faceplate assembly coupled to the pantograph mechanism;
- and
- a view window extending through the handler, wherein the view window is not obstructed by parts of the handler when the handler is in any normal operating configuration, wherein the view window extends along a longitudinal center line of the handler, with the longitudinal center line passing through the view window, wherein the view window has a cross-section orthogonal to the longitudinal center line of the handler with a height of at least 20 inches.
A high visibility push-pull handler configured to be mounted on a lift truck comprising:
- a frame assembly;
- a top hook assembly configured to couple with the frame assembly;
- a pantograph mechanism coupled to the frame assembly;
- a faceplate assembly coupled to the pantograph mechanism;
- and
- a view window extending through the handler, wherein the view window is not obstructed by parts of the handler when the handler is in any normal operating configuration;
- wherein the pantograph mechanism comprises a left inner arm, a right inner arm, a left outer arm and a right outer arm wherein the left inner arm and the right inner arm each have two distal ends, one distal end coupled to the frame assembly by an inner primary arm pivot pin and another distal end coupled to the faceplate assembly by an inner secondary arm pivot pin;
- and
- wherein the pantograph mechanism further comprises an inner arm cross bar coupled to the left inner arm and the right inner arm between and not at the inner secondary arm pivot pins and the inner primary arm pivot pins such that the inner arm cross bar is no higher than a top hook bar of the top hook assembly when the handler is in any normal operating configuration.
A high visibility push-pull handler configured to be mounted on a lift truck comprising:
- a frame assembly;
- a faceplate assembly comprising a faceplate with a faceplate center opening;
- and
- a pantograph mechanism comprising a left inner arm, a right inner arm, a left outer arm, a right outer arm, wherein the left inner arm and the right inner arm each have two distal ends, one distal end coupled to the frame assembly by an inner primary arm pivot pin and another distal end coupled to the faceplate assembly by an inner secondary arm pivot pin, wherein the left inner arm and the right inner arm are only further coupled by a single structure that is between and not at the inner secondary arm pivot pins and the inner primary arm pivot pins and within a distance from one of the distal ends of the inner arms that is no more than one quarter of a length of one of the inner arms.
