Contact tip movable
Frequently Asked Questions
Q: What does a contact tip movable do in a lift truck?
A: CR 79802 is the movable contact component in an electrical contactor assembly. It creates and breaks electrical connections under control of solenoids or mechanical linkages to switch power on and off for lift motors and control circuits.
Q: Which Crown lift truck models use CR 79802?
A: CR 79802 is used in Crown electric lift trucks with contactor-based electrical control systems. Verify your equipment model, serial number, and production year against Crown documentation to confirm fitment.
Q: What are the specifications for this movable contact?
A: CR 79802 is manufactured to specific electrical and mechanical standards. Specifications include contact material, contact surface area, voltage rating, amperage capacity, and movement distance. Verify all details match your original equipment.
Q: How do I know if the movable contact needs replacement?
A: Replace CR 79802 if you observe chattering or arcing when the contactor operates, visible pitting or erosion on the contact surface, inability to complete electrical circuits, or intermittent loss of power to lift or drive functions.
Q: What is the typical service life of this contact tip?
A: Contact tips typically last 2-5 years depending on switching frequency and electrical load. Frequent operation or high-amperage circuits reduce lifespan. Corrosive or wet operating environments accelerate contact degradation.
Q: Are there equivalent or cross-reference part numbers for CR 79802?
A: CR 79802 is a Crown OEM part. Verify compatibility before substituting with aftermarket contacts, as electrical specifications and mechanical fit must be exact to ensure proper contactor operation and lift truck safety.
