Frequently Asked Questions
Q: Which lift truck models use the BR 28802-20 brush set?
A: The BR 28802-20 is an OEM Barrett brush set for electric lift trucks. This part is a direct replacement for Barrett equipment with matching OEM brush holder configurations. Verify your specific model and brush holder design against this part number to ensure compatibility.
Q: What material composition makes up the BR 28802-20 brushes?
A: The BR 28802-20 brush set features carbon-graphite composite brushes with integral coil spring assembly. Carbon-graphite provides electrical conductivity, thermal stability, and wear resistance required for continuous duty in electric motor applications on material handling equipment.
Q: What are typical failure symptoms for worn BR 28802-20 brushes?
A: Worn BR 28802-20 brushes cause reduced motor speed and power output, increased noise or chattering during operation, visible sparking at the brush holder, and intermittent motor performance. Loss of lifting speed is a common indicator. Replace brushes when performance degradation is evident to prevent commutator damage.
Q: How long do BR 28802-20 brushes last in service?
A: Brush service life typically ranges from 1000 to 3000 operating hours under normal duty cycles. High-intensity or continuous heavy-load operations reduce lifespan. Commutator surface condition, voltage regulation, and maintenance practices directly affect brush wear rate. Monitor performance during routine maintenance intervals.
Q: Are there alternative part numbers for the BR 28802-20?
A: The BR 28802-20 is the OEM Barrett specification. Use only the exact part number when ordering replacements. Cross-referencing brush sets across different manufacturers or equipment lines risks improper fit and electrical incompatibility. Refer to your lift truck documentation to confirm the correct replacement part.
Q: What maintenance extends the life of BR 28802-20 brushes?
A: Maintain brush life by keeping the commutator clean and smooth, ensuring proper voltage regulation, and avoiding extended operation at reduced speed with heavy loads. Inspect brushes visually during routine maintenance. Replace promptly when worn to prevent commutator scoring and motor damage.
