CONTACT KIT (EV1)
Frequently Asked Questions
Q: What is the 972747 contact kit (EV1) used for?
A: The 972747 is a contact kit assembly for electric lift truck control systems. The EV1 designation identifies this as an electrical contact component that operates within the lift truck control circuit. It manages electrical current flow for lift, lower, or movement functions.
Q: Which electric lift truck models use the 972747 contact kit?
A: The 972747 is compatible with electric lift trucks from Crown, Toyota, Mitsubishi, Caterpillar, Jungheinrich, and other OEMs using EV1-style contact assemblies. Verify your lift truck model and control system type before ordering to confirm fitment.
Q: What is the difference between the 972747 and other contact kits?
A: The EV1 designation specifies a particular contact configuration and electrical rating. Different contact kits (EV2, EV3, etc.) have different switching characteristics and are not interchangeable. Confirm your lift truck electrical schematic specifies EV1 contacts before substituting.
Q: What happens if the 972747 contact kit fails?
A: Failure symptoms include loss of control function, intermittent lift or lower operation, or complete electrical shutdown. Symptoms depend on which control circuit is affected. Contact kit failure typically prevents normal lift truck operation and requires replacement to restore function.
Q: What is the service life of the 972747 contact kit?
A: Contact wear depends on electrical load, switching frequency, and duty cycle. Heavy-duty applications may require replacement every 1-2 years. Light-duty applications may last 3-5 years. Monitor for intermittent electrical faults and replace preventively to avoid unexpected downtime.
