An industrial vehicle comprising a tag reader, a reader module, and a diagnostic tag, wherein the diagnostic tag is coupled to the industrial truck within a read range of the tag reader. The reader module and the tag reader cooperate to identify the diagnostic tag and individual tags of a tag layout and the reader module discriminates between the individual tags of the tag layout and the diagnostic tag and the individual tags of the tag layout, correlates an identified individual tag of the tag layout with tag data, correlates an identified diagnostic tag with operation of the tag reader, and generates a missing tag signal if the diagnostic tag is not identified or the operation of the tag reader is not within specified operating parameters.

A wheel assembly including a sensor for measuring wheel movement is provided comprising: a frame member; an axle fixed to the frame member; a wheel rotatably mounted to the axle and comprising wheel recess; a code ring located within the wheel recess for rotation with the wheel; and a sensor device coupled to the frame member and located adjacent to the code ring. The sensor device senses movement of the code ring and generates an output signal indicative of the wheel movement. A materials handling vehicle comprising the wheel assembly is also provided.

A system includes a remote control device that is useable by an operator interacting with a materials handling vehicle. The remote control device includes a wireless communication system including a wireless transmitter and a rechargeable power source. The system further comprises: a receiver at the vehicle for receiving transmissions from the wireless transmitter; a controller at the vehicle that is communicably coupled to the receiver, the controller being responsive to receipt of transmissions from the remote control device; and a charging station at the vehicle, the charging station for charging the rechargeable power source of the remote control device.

On-board charging station for a remote control device

A remote control device that is paired with a first vehicle, such that the remote control device wirelessly communicates with the first vehicle, is paired with a second vehicle via a pairing process. The pairing process is initiated by physically contacting a component of the remote control device with an element of the second vehicle. The pairing process also unpairs the remote control device from the first vehicle, such that the remote control device no longer wirelessly communicates with the first vehicle, and the remote control device wirelessly communicates with the second vehicle.

A wheel assembly including a sensor for measuring wheel movement is provided comprising: a frame member; an axle fixed to the frame member; a wheel rotatably mounted to the axle and comprising a wheel recess; a code ring located within the wheel recess for rotation with the wheel; and a sensor device coupled to the frame member and located adjacent to the code ring. The sensor device senses movement of the code ring and generates an output signal indicative of the wheel movement. A materials handling vehicle comprising the wheel assembly is also provided.

A diagnosis system for materials handling vehicles leads service personnel step-by-step through diagnosis and repair of faults within the vehicle. Faults are assigned corresponding event codes so that when a fault is detected, its corresponding event code is displayed. The event codes uniquely identify systems of the vehicle in which faults have occurred by having the event codes for a given vehicle system all start with the same number. Thus, the technician knows from the event code what system needs to be diagnosed/repaired and what tools and probable parts will be needed. The event code is used to access diagnosis information identifying the portion of the vehicle wherein the malfunction has occurred, the components which caused the malfunction and, preferably, provides a pictogram of that portion of the vehicle. The technician advances to the malfunctioning portion of the vehicle where another pictorial depiction of the components of that portion of the vehicle assists in locating the components. All components are marked within the vehicle by identifiers which are consistently used throughout the diagnostic information, pictorial representations and service manuals. The diagnostic information tells the technician what to do to diagnose the components with the diagnosis being preformed using the electronic control system of the vehicle to monitor inputs to and outputs from the electronic control system and to apply limited duration full power test signals to components to be tested. The diagnostic information is configured so that testing is done from the end of control paths back to the controller.
