Abstract: Provided are systems and methods for enclosing an energy source of a material handling vehicle. The systems and methods include an enclosure having a front wall, a rear wall, and an interior compartment, an inlet channel integrally formed with the front wall and in fluid communication with the interior compartment, the air inlet channel defined by an inlet louver and an inlet flange, an outlet channel integrally formed with the rear wall and in fluid communication with the interior compartment, the air outlet channel defined by an outlet louver and an outlet flange, one or more energy source cells positioned within the interior compartment; and a cooling fan in fluid communication with the inlet channel and the interior compartment. The cooling fan operates to draw air through the inlet channel to the interior compartment such that air within the interior compartment is expelled out of the outlet channel.

Abstract: Extendable mast systems and methods for a material handling vehicle include a base mast having a first web connecting a first web first flange and a first web second flange; a base mast bearing; a base mast bumper; a vertically extendable mast having a second web connecting a second web first flange and a second web second flange; and a vertically extendable mast bearing. The base mast bearing is spaced apart from the second web first flange defining a base mast bearing space between the base mast bearing and the second web first flange. The vertically extendable mast bearing is spaced apart from the first web first flange defining a vertically extendable mast bearing space between the vertically extendable mast bearing and the first web first flange. And the base mast bumper maintains the base mast bearing space between the base mast bearing and the second web first flange.

Abstract: Systems and methods for mast stabilization on a material handling vehicle are provided. In one aspect, the present disclosure provides systems and methods for a hydraulic circuit configured to stabilize a mast of a material handling vehicle in dynamic and static events. The hydraulic circuit is integrated into a typical hydraulic system used to raise and lower the mast and thereby a load supported by the mast.

Abstract: Load centering devices and methods for a material handling vehicle are provided. In particular, load centering devices and methods are provided that enable a load to be centered with respect to load carrying forks on a material handling vehicle when the load is raised and/or lowered by the forks.

Abstract: A material handling vehicle with a rack sensor arranged on the one or more base legs is provided. The rack sensor is configured to detect a racking feature of a racking structure to provide an indication to an operator that the material handling vehicle is correctly positioned to transport a load to and from the racking structure.

Abstract: Provided are systems and methods for monitoring the position of a handle of a material handling vehicle comprising a handle, a first sensor positioned along the material handling vehicle, a second sensor positioned along the handle, and a controller configured to retrieve first positional information from the first sensor, retrieve second positional information from the second sensor, and compare the first positional information with the second positional information. The controller can adjust the operation of at least one of a lift motor and a drive motor of the material handling vehicle based on the comparison of the first positional information with the second positional information.

Abstract: Provided are systems and methods for adjusting an armrest assembly, the assembly comprising an armrest that includes an armrest pad, a rising platform having a nut aperture, a nut positioned within the nut aperture. The assembly further includes a rod assembly coupled with the armrest, an adjustment mechanism for raising or lowering the armrest, and may include one or more rotation stops coupled with a stationary plate.

Abstract: A lift truck can include a mast and a lift cylinder. The lift cylinder can include a piston rod and a cylinder housing. The lift truck also can include a piston rod retention mechanism that restricts movement of the lift cylinder in a direction lateral to an axial direction when the mast is in an extended position.

Abstract: A system for transmitting data between components of an industrial vehicle that are powered by electricity received through a power line is provided. The system includes a first electrical choke with a conductor arranged to pass through the first electrical choke and to connect a first component to the power line, and a first communication circuit for at least one of sending and receiving signals and having a transmission wire for carrying the signals. When the first communication circuit transmits a communication signal, the communication signal passes along the transmission wire through the first electrical choke in a first direction, and subsequently the communication signal passes along the conductor through the first electrical choke in a second direction opposite to the first direction thereby cancelling attenuation of the communication signal by the first electrical choke.

Abstract: One or more material handling vehicles of a fleet can be equipped with telematics controllers and configured for wireless communication. In different arrangements, the material handling vehicles of the fleet can communicate with each other and with a management system, in order to effect management of the fleet and of particular material handling vehicles belonging thereto.

Abstract: A wheel assembly includes a constant force mechanism and a wheel coupled to the constant force mechanism. The wheel is displaceable in at least one dimension, and the constant force mechanism imparts a substantially constant force on the wheel in the dimension. In one aspect, the wheel is displaceable in a first regime and a second regime. For a wheel displacement in the first regime, the constant force mechanism imparts a substantially constant force on the wheel, and for a wheel displacement in the second regime, the constant force mechanism imparts a variable force on the wheel. The variable force can be linear or non-linear to the magnitude of the displacement in the second regime and is equal to or greater than the substantially constant force.

Abstract: A floor suspension system for a material handling vehicle is provided. The floor suspension system includes one or more coupling assemblies to couple a battery compartment and an operator compartment of the material handling vehicle to a fork frame of the material handling vehicle. The one or more coupling assemblies each include a first pivot arm to pivotally couple the battery compartment to the fork frame, a second pivot arm to pivotally couple the operator compartment to the fork frame, and a coupling arm to couple the first pivot arm to the second pivot arm. The floor suspension system further includes a spring assembly having a spring pack pivotally coupled to the fork frame and the battery compartment.

Abstract: An operator ride enhancement system that is coupleable to the frame of a vehicle includes a counterweight platform moveably coupled to the frame, and a resilient member engaged with the frame and the counterweight platform. The mass of the counterweight platform is configured to be approximately at least equal to a total mass supported by the counterweight platform during operation of the vehicle. The operator ride enhancement system attenuates and/or inhibits movement of the counterweight platform during operation of the vehicle.
