Frequently Asked Questions
Q: What is the difference between BA 993807 and BA 993811 contacts?
A: Both are contact tips for lift truck control circuits but may differ in size, voltage rating, or alloy composition. The BA 993811 is optimized for specific contactor models or voltage systems. Verify your equipment requires BA 993811 specifically, as mixing contact types can cause circuit failure.
Q: What voltage rating does the BA 993811 contact support?
A: Confirm the BA 993811 voltage rating (24V or 36V DC) against your truck electrical system. Using contacts rated for the wrong voltage risks coil burnout and contact failure. Cross-reference with your equipment documentation to ensure proper specification match.
Q: What is the expected service life of BA 993811 contacts?
A: These contacts typically endure 2,000 to 5,000 engagement cycles before wear becomes visible. In active-duty pallet jacks, this translates to 2 to 4 years of service. Preventive replacement during scheduled maintenance intervals prevents unexpected control circuit failure.
Q: Which lift truck models and control circuits use BA 993811 contacts?
A: The BA 993811 fits contactor and motor starter assemblies in Crown, Toyota, Raymond, Yale, and Hyster electric lift trucks. Compatibility depends on the specific contactor frame size and control voltage. Verify part fitment with your truck model year and serial number.
Q: How can you tell if BA 993811 contacts are worn and need replacement?
A: Worn contacts show arcing or burning at the connection point, reduced contact surface area from pitting, intermittent motor engagement, or audible chattering when the control switch is activated. Any of these symptoms warrant immediate contact replacement to restore reliable motor control.
