20 Mar: 21 Nos Gantries Synchronous Movement for handling 260M long Rails – CASE STUDY

A CASE  STUDY 21 No Gantries Synchronous Movement for handling 260M long Rails by  M/S. REVA INDUSTRIES LIMITED FARIDABAD Project : DDFC – Tata Aldesa – Bhadan, Kanpur and Aliargh Commissioning date -December 2014  Project Requirement: Tata Aldesa was awarded order for dedicated freight corridor. The requirement was that 260M long rails would have to be unloaded from BFR and loaded onto Track Laying Machine. For this application 21 nos of Gantries each with 2t hoist, lifting beam were required. these gantries were spaced @12.5M apart. The application required all 21nos of gantries or group of 7 or 4 or individual to be operated as per application use. Handling area Span: 260m X 20 m Height of Lift: Approx. 6.0 meters.
