Frequently Asked Questions
Q: What electric lift trucks use the 138880 24 volt contactor?
A: The 138880 is a 24 volt contactor used in Crown, Toyota, Raymond, and Yale electric pallet jacks and reach trucks. This contactor controls main motor power for lift and drive circuits in 24 volt DC systems. Verify your truck voltage before ordering, as 36 volt systems require different contactors.
Q: What is the amperage rating of the 138880 contactor?
A: The 138880 is rated for specific amperage loads typical of 24 volt lift motor circuits, generally 100 to 250 amps depending on motor size. Exceeding rated amperage causes contact welding and permanent contactor failure. Do not bypass the contactor or use it in higher voltage applications.
Q: What symptoms indicate the 138880 contactor has failed?
A: Signs of contactor failure include truck not responding to lift or drive commands, humming from the contactor without motor engagement, visible arcing or burning marks, or complete loss of power. Check for blown fuses or dead battery before assuming contactor failure, but replace if contacts show pitting or discoloration.
Q: How long does the 138880 contactor typically last?
A: A 24 volt contactor typically lasts 5 to 10 years depending on load cycling frequency and electrical cleanliness. Heavy-use equipment with frequent motor engagement experiences faster contact wear. Preventive replacement during major electrical overhauls improves uptime and prevents sudden truck failure.
Q: Can the 138880 be used as a direct replacement in any 24 volt truck?
A: The 138880 must match original contactor specifications for mounting hole pattern, coil voltage, contact configuration, and auxiliary switch design. Verify mounting bracket compatibility and coil connector type before ordering. Using a mismatched contactor can cause wiring damage or complete electrical system failure.
