OZ Lifting HVACR Davit Crane Rooftop Maintenance System
Heating, ventilation, air conditioning and refrigeration (HVACR) contractors are frequently required to lift heavy and awkwardly shaped loads to the rooftops of buildings.

A Davit Crane Rooftop Maintenance System from OZ Lifting Products is solving material handling problems for small crews with a portable solution that allows them to lift from the building exterior.
Air handling units and condensing kits that provide heating, cooling, and ventilation for multiple spaces are all stored on building roofs, along with exhaust fans and rooftop ductwork.
While this is convenient in that it saves space inside, it is a logistical challenge raising them into position, when elevators and stairways are inaccessible or inappropriate.
OZ Lifting’s fully customized Davit Crane Rooftop Maintenance System is a versatile material handling solution designed to optimize efficiency and safety in HVACR applications.
“The skilled labor shortage is a real pain-point right now,” said Steve Napieralski, president at OZ Lifting. “Even as we’re speaking to HVACR and plumbing professionals, we can see them planning out their own tailor-made lifting solution in their head.”
He noted that the cost savings, along with productivity and safety gains, are immediately apparent.
“Rooftop lifting is a problem every one of these guys and gals deals with every day and we’ve got the solution,” Napieralski said. “Companies can now do more with fewer people, without cutting corners on safety.”

In a recent case study on a five-story commercial building, the install crew ran into a an access issue because the service elevator was too small for the rooftop unit and the stairwell wasn’t a safe or realistic option.
Using an OZ Lifting Rooftop Maintenance System with an adjustable davit crane, the crew was able to lift and place the components directly on the roof with a smaller team and more efficient solution.
It is possible to choose from various davit crane models, ranging from 500 to 2,500 lbs. in capacity; and four base styles, with different finishes.
Other options include manual or electric winch; wire or synthetic rope; plus, accessories. Contractors can already spec a system for their unique requirements, while a seventh davit crane model and fifth non-permanent base will join the family this year.
Portability and tool-free assembly combine with the ability to own one crane with multiple bases, making it easy to move the crane around sites as needed.
All OZ Lifting davit cranes have the same basic features: U.S.-Patented tool-free assembly; corrosion-resistant finish; and adjustable booms, but specific models have added features.
“Our Davit Crane Rooftop Maintenance Systems are specifically designed for the material handling requirements of the HVACR industry, which is running smaller crews than ever,” Napieralski said. “The U.S.-Patented quick-connect tool-free setup is a gamechanger.”
