What is a Hand Brake Set for LHB Power Car Coach?
The Hand Brake Set for LHB (Linke Hofmann Busch) Power Car Coach is a vital safety and parking brake mechanism used in modern Indian Railways coaches. It facilitates manual application of braking force to the train’s bogie-mounted disc brakes. This system ensures the train remains stationary during stops or emergencies, especially when air brakes might be inactive.
Key Features of Hand Brake Set for LHB Power Car Coach
Flex-Ball Cable Actuation
Uses flexible ball cables directly connected to the hand wheel, transmitting manual force to the brake calipers for smooth and efficient brake application.
Dual Caliper Setup
Equipped with two brake calipers per bogie positioned diagonally opposite for balanced braking and enhanced safety on both sides.
Indicator Integration
Includes hand brake indicators that visually display the brake status (applied or released), enhancing operational awareness and safety.
Robust Mechanical Linkage
Constructed from high-strength materials with precision joints to withstand repetitive manual operation and heavy mechanical stress.
Check Valve and Pressure Tank
Contains a dedicated check valve and a 6-liter pressure tank on the control panel to maintain brake system reliability and responsiveness.
Manual Brake Application: Allows train operators to apply brakes manually via a hand wheel during parking, emergencies, or system failures.
Brake Status Indication: Provides real-time visual feedback on brake engagement status through indicators visible on the side of the power car.
Balanced Force Distribution: Ensures equal braking effort on both bogies by actuating brake calipers diagonally, improving stability.
Cable Transmission Efficiency: Flex-ball cables transmit force with minimal friction or backlash, ensuring precise brake control.
Safety Redundancy: Functions as a fail-safe braking system supplementing the primary pneumatic brakes.
Eases Maintenance: Modular assembly design with accessible components simplifies inspection, adjustments, and repairs.
Integration with Air Brake System: Synchronizes with the main air brake system for coordinated braking performance across the coach.
