Frequently Asked Questions
Q: What is the BR 28802-14 brush used for in electric lift trucks?
A: The BR 28802-14 is a brush assembly for electric lift truck motors and generator systems. Brushes maintain electrical contact between rotating and stationary components in DC motors, generators, and pump drive motors. The BR 28802-14 is specifically designed for Barrett electric lift truck systems.
Q: How often should the BR 28802-14 brush be replaced?
A: The BR 28802-14 brush typically lasts 2,000-3,000 operating hours depending on load cycles and electrical demand. In high-duty applications with frequent acceleration and heavy load lifting, replacement may be required every 18-24 months. Monitor motor operation for sparking or noise that indicates brush wear.
Q: What symptoms indicate the BR 28802-14 brush needs replacement?
A: Replace the BR 28802-14 when experiencing visible motor sparking, a burning smell from the motor, reduced motor power output, grinding noise from the motor, or loss of generator charging function. These symptoms indicate brush wear and imminent commutator damage if replacement is delayed.
Q: Which Barrett lift truck models use the BR 28802-14 brush?
A: The BR 28802-14 brush is designed for Barrett electric pallet jacks, walkie trucks, and ride-on lift trucks. It fits drive motors, generator assemblies, and pump motors depending on equipment configuration. Confirm your specific Barrett model and motor location before ordering to ensure correct fitment.
Q: What is the brush material composition of the BR 28802-14?
A: The BR 28802-14 uses carbon-composite brush material formulated for DC motor commutator applications. Carbon-composite material provides balanced electrical conductivity and mechanical durability in high-cycle motor applications. The material is formulated for the specific current draw and RPM range of Barrett lift truck motors.
