Frequently Asked Questions
Q: What is the material composition of the YL 516858808 contact tip?
A: The YL 516858808 is constructed from conductive copper alloy with a silver plated surface. This material combination ensures reliable electrical conductivity and current transfer in Yale electric lift truck control circuits. The silver plating provides corrosion resistance and maintains low contact resistance over the service life of the component.
Q: Which Yale electric lift trucks is the YL 516858808 contact tip compatible with?
A: The YL 516858808 fits selected Yale pallet jack contactor assemblies used in Yale electric lift truck applications. This is an OEM component designed for Yale control systems. If you are unsure whether this part matches your specific equipment model or serial range, verify the contactor assembly part number on your truck before ordering.
Q: What are the cross-reference and equivalent part numbers for YL 516858808?
A: The YL 516858808 contact tip has the following cross-reference and equivalent part numbers: SK-13250114A, U4904, YT 516858808, and YT516858808. These numbers indicate compatibility with replacement applications and different supplier references for the same OEM component.
Q: What is the function of the contact tip in a Yale electric lift truck contactor assembly?
A: The contact tip is a critical electrical component in the contactor assembly that facilitates current transfer between the truck battery and control circuits. Worn or damaged contact tips can result in poor electrical connections, erratic control system behavior, or failure of the truck to respond to operator commands. Replacement is part of routine maintenance on electric lift trucks.
Q: How do I know if the YL 516858808 contact tip needs replacement?
A: Symptoms of a worn contact tip include intermittent electrical faults in the control system, difficulty starting the truck, or inconsistent response to control commands. Visual inspection of the contactor assembly may reveal pitting, discoloration, or corrosion on the contact surfaces. If you suspect a failed contact tip, compare your truck model and contactor assembly part number to the YL 516858808 compatibility.
Q: What is the service life expectancy of the YL 516858808 contact tip?
A: Contact tip lifespan depends on duty cycle, frequency of contactor activation, and environmental conditions. High-duty cycle trucks in cold storage or wet environments may require more frequent replacement than light-duty indoor applications. The silver plating and copper alloy construction are designed for durability, but regular inspection of the contactor assembly is recommended as part of preventive maintenance on electric lift trucks.
