Specification: 100–3,000+ Ton Heavy Rigging • 0.78 EMR • Sub-Basement Knockdowns
Engineered chiller condenser and compressor lift-and-shift rigging, heavy hydraulic crane picks, knocked-down subterranean chiller assembly, and turnkey central plant replacements (100–3,000+ tons).
Direct Engineering Summary: Chiller Rigging, Lift-and-Shift & Turnkey Plant Replacement
Replacing a multi-ton centrifugal compressor, retubing a 12,000-lb condenser barrel, or swapping a 1,200-ton chiller inside a sub-basement or high-rise penthouse requires precision heavy mechanical rigging paired with certified union pipefitting. Western Mechanical, Inc. (CSLB #618138: C-38, C-20, C-4; 0.78 EMR; 100% UA Local 250) executes turnkey chiller lift-and-shift rigging, subterranean knock-down reassemblies, crane picks, and HCAI seismic anchorage across Southern California: (661) 251-0111.

Engineering Scope & Southern California Field Execution
Replacing a 500-ton centrifugal compressor, rigging a new shell-and-tube condenser barrel into a sub-basement central plant, or executing a rooftop air-cooled chiller crane pick requires heavy industrial millwright precision, ASME certified pipe welding, and zero-incident safety governance. Western Mechanical, Inc. (CSLB #618138: C-20, C-38, C-4; 0.78 EMR safety rating) manages turnkey chiller lift-and-shift rigging and full central plant replacements across Southern California. Whether craning a 35,000-lb York YK / Trane CenTraVac over an active hospital wing under HCAI (OSHPD) seismic anchorage rules, or disassembling a modular magnetic-bearing chiller to rig through standard 48-inch penthouse doors via gantry, air skates, and chainfalls, our UA Local 250 steamfitters handle EPA Section 608 refrigerant recovery, temporary mobile rental chiller tie-ins, rigging, piping, VFD integration, and factory startup.
Compressor & Heat-Exchanger Lift-and-Shift Rigging Inside Tight Subterranean Central Plants
Many Downtown Los Angeles high-rises, Beverly Hills medical plazas, and university central plants house chillers two to four levels below grade with zero crane access and narrow concrete corridors. Hoisting a 6,500-lb semi-hermetic screw or open-drive centrifugal compressor off a top-mounted shell without damaging copper oil tubing or vessel flanges requires engineered gantry and chain-fall geometry.
Western Mechanical sets certified aluminum/steel A-frame gantries, Hilman high-capacity machine rollers, and hydraulic toe jacks—executing field knock-downs (separating compressor, motor, economizer, evaporator, and condenser barrels), rigging through louver shafts, and re-welding/brazing ASME/ANSI B31.5 refrigerant and hydronic headers.
High-reach rooftop chiller and cooling tower picks across congested hospital campuses and urban streets leave zero margin for rigging miscalculation or unexpected facility downtime.
Backed by our 0.78 EMR safety program, we coordinate stamped crane outrigger bearing-load engineering, FAA/DOT municipal permits, pre-piped temporary rental chiller bypasses, OSHPD/HCAI seismic spring isolators, and factory-witnessed start-up commissioning.

What does a chiller compressor or condenser lift-and-shift service include?
A chiller lift-and-shift encompasses EPA-compliant refrigerant pump-down and recovery, electrical and chilled-water isolation, engineered gantry/crane rigging to extract a failed semi-hermetic/centrifugal compressor or fouled condenser shell, setting and torquing the replacement assembly, nitrogen pressure/vacuum dehydration, and full load commissioning.
How do you replace a central plant chiller trapped in a basement with no crane access?
We engineer knocked-down rigging solutions—either rigging separate evaporator, condenser, and compressor sub-assemblies on heavy machinery skates through mechanical corridors, or installing modular magnetic-bearing chillers (such as Multistack or Daikin Magnitude) designed to roll through standard freight elevators.
Can our hospital or manufacturing plant stay cooled while you rig and replace the chiller?
Yes. Prior to shutting down your existing chiller, our UA Local 250 pipefitters install flanged bypass taps and tie in a temporary trailer-mounted rental chiller and pump package so chilled-water supply stays uninterrupted 24/7.
