  • Publication number: 20200317484
    Abstract: A pallet detection assembly for a material handling vehicle is provided. The pallet detection assembly includes a body defining a cavity and having a proximity sensor housed at least partially within the cavity. The pallet detection assembly further includes an actuation plate having a tab coupled thereto and extending in a direction toward the body, and an actuator having a cylinder coupled to the body and a plunger slidably received within the cylinder and coupled to the actuation plate. The actuator is configured to movably couple the actuation plate to the body so that the actuation plate is configured to non-pivotally displace relative to the body.

  • Publication number: 20200317150
    Abstract: A bumper assembly for a material handling vehicle is provided. The material handling vehicle includes a vehicle frame. The bumper assembly includes a first bumper coupled to a first side of the vehicle frame and having a first slot extending along a portion of the first bumper and a first protruding portion. The first protruding portion extends outwardly at an angle past a plane defined by the first side of the vehicle frame. The bumper assembly further includes a second bumper coupled to a second side of the vehicle frame opposite to the first side and having a second slot extending along a portion of the second bumper and a second protruding portion. The second protruding portion extends outwardly at an angle past a plane defined by the second side of the vehicle frame.

  • Publication number: 20200317483
    Abstract: A load handling module for a material handling vehicle can include a first camera configured to determine the position of an object in a first camera field of view, and a second camera positioned above the first camera and configured to determine the position of an object in a second camera field of view. A fork tip sensor can be secured to at least one fork proximate the tip end thereof, and can be configured to detect the presence of an object within a fork sensor field of view extending in front of the fork. A controller can be in communication with the first sensor, the second sensor, and the fork tip sensor, the controller being configured to autonomously control the material handling vehicle to pick up or drop-off a load.

  • Publication number: 20190308858
    Abstract: The present disclosure provides systems and methods for detecting a load on at least one fork of a material handling vehicle. The systems and methods can comprise a housing; at least one sensor positioned within the housing; a sensor arm pivotally coupled to the housing; at least one sensor flag integral with or coupled to the inside of the sensor arm; and wherein when the sensor arm pivots inward toward the housing the at least on sensor flag triggers the at least one sensor to identify at least a first load position and a second load position.
