Abstract: A wheel assembly includes a wheel having an axle, and a constant force mechanism coupled to the wheel. The constant force mechanism includes a horizontal support, a horizontal carriage associated with the horizontal support, a vertical support oriented perpendicular with respect to the horizontal support, a vertical carriage associated with the vertical support, and a rigid arm that is pivotally coupled with the horizontal carriage, the vertical carriage, and the axle. The rigid arm is coupled with the vertical carriage at a point intermediate where the rigid arm is coupled with the horizontal carriage and the axle. The horizontal carriage is capable of being urged along the horizontal support, and the vertical carriage is capable of being urged along the vertical support.

Abstract: Some aspects of the present disclosure provide a material handling vehicle configured for selectively coupling with any of a plurality of material handling attachments. In some configurations, the material handling vehicle includes a vehicle frame and a universal mounting assembly. The universal mounting assembly includes a universal mount coupled to the vehicle frame and having at least one linear actuator and at least one hinge, and a universal frame having at least one cradle rod pivotally coupled to the hinge and at least one bracket coupled to the linear actuator. Selective actuation of the at least one linear actuator pivots the universal frame relative to the vehicle frame.

Abstract: A method of controlling a hydraulic control system of a material handling vehicle is provided. The method includes detecting an elevated height of a fork assembly, determining if the elevated height is above a first predetermined height threshold, and actuating a first low pressure control valve from a control valve closed position to a control valve open position to provide fluid communication from a supply passage to the first low pressure relief valve when the elevated height is above a first predetermined height threshold.

Abstract: Systems and methods for material handling vehicle simulation are provided. In one aspect, a material handling vehicle simulation system includes a material handling vehicle having a plurality of controls operable to manipulate the material handling vehicle to perform a desired operation, and a vehicle controller configured to selectively transition between a standard mode where the vehicle controller is configured to instruct the vehicle to perform standard operating tasks and a simulation mode. The material handling simulation system further includes a simulation kit having a simulation display, and a simulation controller in communication with the plurality of controls and the simulation display. When the vehicle controller is in the simulation mode, the simulation controller is configured to simulate operation of the material handling vehicle on the simulation display in response to manipulation of at least one of the plurality of controls.

Abstract: A modular battery system for use with a material handling vehicle, the modular battery system comprises a battery assembly and a counterweight assembly. The battery assembly can include a power source and a battery base, and the counterweight assembly can include a counterweight base configured to slidably receive the battery base and be removably secured thereto.

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: Some aspects of the present disclosure provide a modular vehicle frame for a material handling vehicle. In some configurations, the modular vehicle frame includes a battery compartment, a handle configured to control a speed and direction of a traction wheel, and a mounting assembly configured to selectively quick-connect to a material handling attachment. In some configurations, the mounting assembly includes a mounting plate having a first side and a second side, at least one pivot block extending from the first side of the mounting plate and configured to provide a pivotal interface with the material handling attachment, and at least one locking latch attached to the second side of the mounting plate and configured to provide a selective locking interface with the material handling attachment.

Abstract: Systems and methods for temperature control for an energy source of a material handling vehicle. The system includes a battery management system in communication with the energy source that can also be in communication with a charger. The system further includes a counterweight case that supports the energy source, and a plurality of resistive heating elements positioned along one or more surfaces of the counterweight case.

Abstract: A hydraulic control system for a material handling vehicle including one or more hydraulic actuators configured to raise and lower a fork assembly attached to a mast of the material handling vehicle is provided. The hydraulic control system is configured to provide multi-stage pressure relief based on a height of the fork assembly.
