Ballastway TRIZ Cases
- Automated Ballast Wing Stowage With Sequenced Actuators
A machine controller sequences lift, pivot, and extension cylinders to place ballast wings in safe stored positions and reduce positioning damage.
- Tamping Unit With Offset Swivel Axes for Narrow Turnouts
A coupled swivel arrangement offsets inner and outer tine axes, reducing lateral space while preserving obstacle adaptability.
- Dual-Screen Ballast Sieving Layout for Compact Conveyor Flow
Parallel ballast screens and merged conveyor routing simplify soiled-ballast flow while preserving capacity and machine flexibility.
- Magnetic Crosstie Detection for Gravel-Covered Tracks
A magnetic circuit and Hall sensor detect rail fasteners through gravel, enabling automatic, damage-avoiding tamping alignment.
- Excavated Material Classification and Fine-Fraction Incineration
Separation, washing, and crushing isolate contaminated fines for incineration while coarse excavated material remains reusable.
- Track Maintenance Machine Sensor Chord Measurement Without Buggy Extension
A track maintenance machine scans the A point with sensors and calculates chord data for workhead control without a buggy system.
- Track Support Slab Transfer With Rotary-to-Translatory Actuation
A single actuating mechanism converts rotary input into horizontal and vertical movement for precise, stable slab transfer.
- Composite Railway Sleeper Sole for Load Distribution and Movement Control
Composite sleeper soles distribute ballast loads and reduce horizontal movement.
- Track Rail Longitudinal Force Measurement With Sleepers Attached
Measure rail longitudinal forces without detaching sleepers or disrupting track.
- Single-Pass Extruded Ballast Protection Film for Waterproofing Membranes
A reactive acrylate coating cures into a skid-resistant film, reducing layers and labor while resisting ballast indentation.
