Frequently Asked Questions
Q: What is the CR 79786 contact used for in Crown lift trucks?
A: The CR 79786 is an electrical contact assembly that forms part of the control or propulsion circuit in Crown electric pallet jacks. It is typically used in motor controllers, solenoids, or main disconnect contactors to complete or break electrical circuits under load.
Q: What Crown models or equipment types use the CR 79786 contact?
A: The CR 79786 contact fits Crown electric pallet jacks and low-level order pickers from specific model generations. It may also be compatible with similar equipment from manufacturers like Toyota or Raymond depending on controller design. Verify equipment serial range and control system type before ordering.
Q: What material is the CR 79786 contact made from?
A: The CR 79786 contact surface is typically made from silver alloy or copper alloy plating over a base material to provide conductivity and minimize arcing. This material resists oxidation and wear from repeated electrical switching.
Q: When should the CR 79786 contact be replaced?
A: Replace the CR 79786 if the truck exhibits intermittent loss of power, slow acceleration, or the controller fails to respond to pedal input. Worn contacts show pitting or discoloration under visual inspection. A burned or severely pitted surface indicates the contact is past service life.
Q: What is the expected service life of the CR 79786 electrical contact?
A: The CR 79786 typically provides 2-4 years of service under normal warehouse duty cycles. Heavy use, frequent acceleration/braking, or harsh electrical conditions may reduce lifespan. Contacts naturally wear from repeated arcing during switching cycles.
