Frequently Asked Questions
Q: What is the primary function of the 121913 solenoid in electric lift truck circuits?
A: The 121913 is a 24VDC main power relay solenoid engineered to control primary power distribution in electric lift truck circuits. It switches the main traction motor and hydraulic pump circuits on and off based on control signals. This solenoid must be rated for continuous duty operation to handle sustained current loads during normal truck operation.
Q: What voltage does the 121913 operate at and what is the coil rating?
A: The 121913 is rated at 24VDC nominal coil voltage. Confirm your truck battery system is a 24-volt system before ordering. Apply only 24VDC to the coil. Using incorrect voltage (12VDC or 48VDC) will destroy the coil or prevent the solenoid from energizing.
Q: Which electric lift truck brands require the 121913 main power relay solenoid?
A: The 121913 is an OEM equivalent main power relay solenoid for 24VDC electric pallet jacks, walkie stackers, and walkie rider trucks from Crown, Toyota, Raymond, Yale, Hyster, Linde, and similar manufacturers. Verify your truck model uses a main power relay circuit and confirm solenoid fitment dimensions match your equipment before ordering.
Q: Is the 121913 rated for continuous duty operation?
A: Yes, the 121913 is rated for continuous duty cycle operation. This means the solenoid can remain energized indefinitely without thermal damage. As the main power relay, it must handle sustained load during normal truck operation. If the solenoid overheats or chatters during normal use, it may be failing and requires replacement.
Q: What is the mounting configuration of the 121913?
A: The 121913 features a bolt-on installation design for mounting to relay panels or contactor assemblies. Ensure mounting bolts are tightened securely and electrical connectors are fully seated. The solenoid must be mounted with adequate airflow to dissipate coil heat during continuous operation.
Q: How do I know if the 121913 solenoid is failing?
A: Signs of 121913 failure include truck loss of power, intermittent power loss, weak mechanical response when energized, or audible coil buzzing during operation. Test coil continuity with a multimeter. If resistance is zero or infinite (open circuit), the solenoid must be replaced. If the truck loses all power, check main relay operation before replacing the solenoid.
