Project
HVAC plant onto several roofs of a new school
Over several visits to a new school in Whitley Bay, we lifted air source heat pumps (ASHPs), a heat recovery unit (HRU), an air handling unit (AHU) and windcatchers onto several roofs, and shifted buffer vessels into a ground-floor plantroom.
The reach needed and the limited access around the buildings meant a standard mobile crane would have been jib bound, and the site had no room to fit a fly jib, so we used a 50m mobile tower crane on contract lift. The rooftop units could be landed straight into their final positions. The buffer vessels were too tall for the plantroom door, so we laid them on their sides on a long bespoke pallet, took them in, stood them back up and shifted them into place.
The client booked crane days around their own build programme and had one contractor for both the rooftop lifts and the plantroom work.

Crane, tackle and team
Crane
A 50m mobile tower crane, set up in three positions across the site. The heaviest lift was the 3.3te AHU at 27m radius; the ASHPs and HRU were up to 1.0te each and the windcatchers 250kg.
Rigging
The windcatchers had four lifting eye bolts and went up on slings and shackles. The AHU, ASHPs and HRU were lifted with a modular spreader beam, web slings and shackles.
Lift and Shift
A telehandler with a jib laid the buffer vessels over onto the bespoke pallet. Inside, we used pallet trucks, beam clamps and chain blocks to stand them up and position them.
Team
Our Appointed Person visited, planned the lifts and prepared the RAMS. On crane days we provided a crane operator, a crane supervisor at ground level and a slinger signaller at roof level. The buffer vessel day had a supervisor, a telehandler operator and an additional rigger.
The Spierings SK599-AT5 is a 9 tonne, five axle mobile tower crane with a 50m jib, supplied with an operator for crane hire or as part of a contract lift.
