If your team has plans to install or maintain rooftop HVAC systems, set them up for success and cut costs by renting or purchasing a reliable HVAC crane from Thern. We are pleased to offer several models with high capacities and long reach to streamline your critical operations and ensure you get your HVAC projects done right.
Choosing the Right HVAC Crane for the Job
Rooftop-mounted HVAC equipment is subject to extreme conditions, from blazing heat and rain to sleet and snow. Placing these large air conditioning units, as well as providing maintenance and emergency repairs require the use of a rooftop davit crane that can withstand the elements. From large filters to repair items like motors, condensers, and fans, your team needs the right HVAC crane to get your parts to where they need to go. The solution? Thern davit cranes.

Our most popular HVAC crane line is our Commander® Series of portable davit cranes, which offer a range in capacity from 650 to 2,000 lbs. Providing optimal flexibility, these cranes can feature various bases that can be installed on the rooftop of a building or parapet wall, allowing for multiple pick points with a single, easy-to-move crane. In addition, we offer manual or drill-drive winches if electrical connections are not readily available, allowing these cranes to fulfill a wide range of roles for HVAC crews. Portable HVAC cranes are ideally suited for maintenance and repair tasks, although some offer enough power to lift rooftop HVAC units for installation. And while they can be moved off the roof when needed, our portable cranes are still designed to stand up to the elements.

For heavy-duty HVAC applications involving a longer reach or greater capacity, our Captain® Series of stationary cranes are available with impressive capacities up to 5,500 lbs. These durable cranes feature extended-length booms for maximum reach on larger loads and an integral slewing drive that withstands large axial, radial, and moment loads while allowing 360 degrees of smooth and easy rotation. While not portable, these cranes are able to handle a wide range of tasks, including precise placement for HVAC unit installation, and critical maintenance parts and replacement equipment. Since they will be continuously exposed to the elements, our stationary davit cranes are also built to withstand the elements and maintain top performance throughout the year.

Thern HVAC Cranes in Action

Thanks to C&C Cranes, Thern’s HVAC cranes can be seen on the sky line in Toronto, Canada. They are being used as a rooftop solution for lifting air exchanger units and other HVAC lifts onto buildings 15 stories or less. In the past, contractors had to use mobile cranes, often resulting in high cost, road closures, and more crew members to get the job done. Using Thern davits as rooftop cranes, HVAC equipment can be lifted for less cost, less labor, and with much easier setup and teardown.

A hospital in the Houston, Texas area was looking to ensure that their HVAC system was well maintained using efficient, reliable equipment and systems. However, the hospital facility is over four stories tall, and the equipment for the HVAC system, including tools, replacement parts, and new units must regularly be brought to the rooftop for maintenance. Bringing this equipment up via the stairwell access is impractical and presents workplace hazards.
The client chose Thern’s 5FT25 Captain davit crane to provide a reliable way to lift equipment to the HVAC units at the hospital. The crane includes a 3WG4 electric winch that makes lifting loads to the top of the four-story building quick and effortless.
