Johnson Controls YORK Chillers — OSAT Semiconductor Facility, Assam

A semiconductor facility under active construction imposes constraints a conventional industrial site does not. The chiller units had to be moved into position inside a partially completed structure — no crane access to the final placement area, restricted headroom, an unfinished floor surface, and the Assam monsoon running through the deployment window. Site access was shared with multiple concurrent contractors, and the units themselves are high-value OEM equipment where surface damage is not recoverable on site.

IPN LIFTERS mobilised a 14-man crew — every member police-verified, medically cleared and enrolled under PF and ESIC before entering site — alongside a dedicated tools and tackles fleet dispatched under formal road challan. With crane access unavailable at the placement point, the units were skidded into position using 100-tonne hydraulic jacks, hydraulic pumps, 18-tonne cargo trolleys and pipe rollers, running on MS plate track laid over the unfinished floor to distribute load. Chain pulley blocks, 10-tonne belt slings and rated shackles handled controlled movement, and the units remained covered throughout to protect finished surfaces. All lifting tackle carried current third-party inspection certification.
