Tunnel Maintenance Special Fixture

The JG multi-valve rotating fixture redefines precise high-altitude operations in the railway industry. It integrates a patented 360° omnidirectional rotation system, breaking through the limitations of traditional fixtures' blind spots. The multi-valve hydraulic control enables micro-adjustment for grasping at the millimeter level, allowing for safe disassembly and assembly of signal cabinets, steel beam supports, and suspended equipment in complex spaces such as tunnel domes and electrified contact nets. The strengthened alloy framework and anti-twist bearings resist lateral impacts, and the automatic anti-sway locking function ensures zero vibration interference during high-speed train passage. As an intelligent railway maintenance fixture, it completely solves the problem of unbalanced loads at high altitudes, increasing the efficiency of bridge maintenance by 300%.
