The Catenary Geometry Parameter Measuring Instrument LJ-JCW-I is a specialized railway measuring device used to measure the spatial parameters of electrified line catenaries and related equipment that provides support and positioning for the catenary. It features a split waterproof design, removable battery, and utilizes high-precision laser ranging, displacement, and angle sensors, along with a high-definition camera for non-contact measurement. The main unit can rotate freely around its axis to meet the measurement needs of various catenary equipment.
Complies with the standard "JJG (Railway) 150-2020 Verification Regulation for Catenary Geometry Parameter Measuring Instruments".
