Contactor Panel Weldment
Frequently Asked Questions
Q: What is the CR 120406 contactor panel weldment and what does it do?
A: The CR 120406 is a contactor panel weldment assembly that functions as the electrical control interface in Crown Wave electric pallet jacks. The contactor panel houses the main power contactor, relays, and electrical terminals that manage current flow to the motor and lift components.
Q: Which Crown models use the CR 120406 contactor panel weldment?
A: The CR 120406 is designed for Crown Wave model pallet jacks and electric lift trucks. Verify your equipment model and serial number range before ordering, as weldment dimensions and electrical configurations are model-specific.
Q: What materials are used in the CR 120406 weldment construction?
A: The CR 120406 contactor panel is a welded steel frame assembly typically finished with industrial paint or powder coating to protect against corrosion in warehouse environments. Internal copper busbars and aluminum components conduct electrical current between terminals and the contactor.
Q: What are common failure symptoms that indicate the CR 120406 contactor panel needs replacement?
A: Symptoms include the truck not responding to joystick commands, intermittent loss of power to the motor, buzzing or clicking relay sounds, burnt electrical smell, visible corrosion at electrical terminals, or tripped circuit breakers. These indicate contactor malfunction or terminal arcing.
Q: How does the CR 120406 contactor panel support the lift and drive functions?
A: The contactor panel switches high-current power to the hydraulic pump motor and lift motor based on joystick input signals. The relays and contactor contacts handle the electrical load switching safely. A properly functioning panel ensures responsive lift and drive operation.
