Overview
Rooftop HVAC units, generators and other equipment often require crane lifts. These lifts involve coordination with mechanical contractors, building owners and sometimes street permits.
Lift planning considers unit weight, rigging, radius to the roof location and setup space. Early morning lifts are common in busy areas.
Rigging points and curb adapters should be prepared before the lift.

Local notes for Colorado Springs
Wind along the Front Range, especially near the foothills, can affect crane operations, and lifts are postponed when conditions exceed limits. Altitude does not change crane load charts, but weather windows and ground conditions after snowmelt matter.
