Lifting a Chiller to a Terrace or Basement: Site Preparation Checklist
Terrace and basement chiller placements fail or succeed before the crane arrives. When a 150–300 tonne crane is on hourly hire and the site isn't ready, every missing permission or uncleared ramp burns money. This checklist is what we walk through with clients before every high or below-grade lift.
Crane positioning and ground
- Confirm crane standing position with a load-chart study for the actual radius and height — not weight alone
- Check ground bearing: outriggers may need steel plates or compacted platforms (on one site, 100 bags of sand prepared the crane apron)
- Identify obstructions in the swing path: lamp posts, cables, trees, parapets — arrange temporary removal in advance
- Verify permissions: society/facility approvals, road closure if the crane stands on a public road, and night-work clearance if required
The landing zone
- Terrace: confirm structural clearance for the landing point load, mark the travel path from landing to foundation, and keep rollers/rails ready
- Basement: finalize the lowering route (cut-out, ramp or shaft), confirm dimensions with the actual unit — not the catalogue drawing — and clear the route of all services
- Foundation ready: cured, level, anchor bolts as per the OEM drawing, vibration pads on hand
Documentation that prevents day-of surprises
- Crane fitness, operator licence and signalman competency certificates
- Test certificates for slings, shackles and spreader beams
- Lift plan shared with the OEM/EHS team where required — JCI, Trane and similar OEMs audit these before permitting work
- Weather call: high-wind criteria agreed in advance for tall lifts
From the field
Nominate one decision-maker from the client side for lift day. Mid-lift is not the time to discover that facility security, the OEM engineer and the building owner each have a different opinion about where the crane may stand.
IPN LIFTERS has executed terrace lifts to 45 m (300 T crane, Peerless Hospital Kolkata), 14th-floor equipment placements, and basement shifts of 450 TR machines. Send us your site photos and the chiller datasheet and we'll tell you what the lift genuinely needs.
Frequently Asked Questions
What information do you need to plan a chiller terrace lift?
The chiller's weight and dimensions (from the datasheet), building height and landing level, photos of the crane standing area and approach road, and the foundation drawing. With these we can do a load-chart study and give a firm method and price.
Can chillers be lifted at night?
Yes, and for sites on busy roads night lifts are often mandatory. It requires lighting, night-work permission from the facility/authorities and sometimes traffic coordination — plan these a week ahead.
What wind speed stops a chiller lift?
Most lift plans set a hold point around 9–12 m/s (about 32–43 km/h) depending on crane, boom length and load sail area. The crane operator's limit is final — a postponed lift is always cheaper than a swinging chiller.
