Systems and methods for transitioning a material handling vehicle between a manual mode and a remote mode is provided. The method includes automatically transitioning the material handling vehicle from the remote mode to the manual mode in response to a determination, by a floor mat sensor, that an operator is positioned within an operator compartment of the material handling vehicle. The vehicle is prevented from entering the remote mode while the floor mat sensor indicates that the operator is positioned within the operator compartment. A mode selection switch, positioned on the material handling vehicle, is actuated from a first position to a second position and back to the first position, permitting the vehicle to enter the remote mode after the floor mat sensor ceases to indicate that the operator is positioned within the operator compartment.

Back pad

A back pad assembly for a material handling vehicle is provided that includes a back pad, a framework, and a mounting frame. The back pad includes a center portion, a first side portion, and a second side portion. The first side portion defines a first curved profile, and the second side portion defines a second curved profile. The first curved profile and the second curved profile are arranged on laterally-opposing sides of the center portion. The framework includes a first mounting bar and a second mounting bar. The framework is coupled to the back pad. The first and second mounting bars are adjustably supported by the mounting frame to enable the back pad to be selectively mounted at varying heights along the mounting frame.

Systems and methods provide a travel control system to augment a supplemental object detection system of a material handling vehicle. Speed limits can be calculated for material handling vehicles based on properties of the vehicle, and a field of view of the object detection systems of the material handling vehicle. For given steer angles or ranges of steer angles, the speed of the material handling vehicle can be limited to ensure that the vehicle could stop before contact with a newly-detected object that was previously outside the field of view of the object detection system.

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.

A method for transferring route information between material handling vehicles is provided. The method includes operating a first material handling vehicle along a route and collecting operation information, transferring the operation information to a warehouse management system that includes a transfer matrix, processing operation information with the transfer matrix, and transferring the processed operation information to a second material handling vehicle.

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.

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.

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.

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.

A hydraulic system has a cylinder and ram assembly that raises and lowers a load carrying carriage on a material handling vehicle. The fluid exhausting from the cylinder, while the carriage is lowering, is controlled to recover energy from that fluid. A first path routes the exhausting fluid to drive the pump as a hydraulic motor. A second path routes the exhausting fluid to a reservoir, bypassing the pump. In a first lowering mode, the second path is closed and the first path is opened. In a second lowering mode, both the first and second paths are open and the flow through each one is proportionally controlled. In a third lowering mode, only the second path is opened. The mode to use is selected based on the desired lowering speed of the carriage.

Automated systems and methods control the velocity of the extension arm of a reach carriage. In particular, the extension arm is allowed to operate at full velocity when it is not approaching its extension or retraction limits. At the limits, the extension arm is gradually slowed to a stop. A sensing apparatus includes a sensor and a marker that moves with the movement of the extension arm. The marker moves into and out of the sensor's range, causing the sensor to generate a position signal. If the extension arm is nearing its limit, the marker is outside the sensor range. A control unit detects changes in the position signal and slows the extension arm accordingly. The control unit may apply a deceleration profile to cushion the extension arm at its limits.
