Frequently Asked Questions
Q: What equipment does the 841850 contact set fit?
A: The 841850 is a contact set assembly for SB50A-series electric lift trucks. This part is compatible with Crown, Toyota, Raymond, and similar OEM equipment using SB50A control systems. Verify your truck model matches the SB50A specification before ordering.
Q: What are the contact materials in the 841850?

A: Common failure signs include intermittent power loss, slow or erratic lift/lower response, visible arcing or pitting on the contact surfaces, or difficulty engaging the direction control. If you see burn marks or hear buzzing from the contactor, the contact set needs replacement.
Q: How long does an 841850 contact set typically last?
A: Contact life depends on duty cycle and electrical load. In typical material-handling environments, contact sets last 2 to 5 years. Heavy-duty or continuous-operation trucks may require replacement every 18 to 24 months due to increased switching cycles.
