HVAC Crane: Setting Rooftop Units Without a Boom Truck

Setting a rooftop unit is often the most expensive hour of an HVAC install. The equipment has to go from the truck to the roof curb, and for most crews that means scheduling a crane service or a boom truck, waiting on its availability, and paying for the whole visit even when the lift takes minutes.

How rooftop units get lifted today

HVAC contractors usually use one of four methods:

• Crane service: a hired mobile crane and operator for the lift.
• Boom truck: a truck-mounted boom, from a rental yard or a supplier.
• Rooftop hoist or gin pole: for lighter equipment on roofs with a suitable anchor point.
• Owned compact crane: a crane the contractor keeps and brings to each job.

For ground-mounted condensers, the challenge is usually getting the unit across the yard to the pad, not up. That is a different problem with its own equipment, such as a towable forklift.

Boom truck vs. crane rental vs. owning a compact crane

Crane rental gives you capacity and reach, but you work on the crane company's schedule. If the install slips, the lift slips with it, and the crew waits.

Boom trucks are faster to book but need a firm, level setup spot close to the building, which residential and small commercial sites often lack.

Owning a compact crane puts the lift on your schedule. The crane travels with the crew and sets up when the curb is ready. The trade-off is that it must match the weight and reach of the units you set most often.

Weight and reach planning

Plan every lift from two numbers: the weight of what you are lifting and the horizontal distance from the crane to where it has to land.

1. Get the actual weight from the unit's data plate or submittal, plus curb adapters, rigging and any packaging left on.
2. Measure the reach from where the crane can safely set up to the center of the curb.
3. Check the load chart for that exact reach. Capacity falls as the boom extends.
4. Confirm the setup surface can support the crane and its outriggers.
5. Check overhead hazards, especially power lines, and follow the required clearances.

Where the Equipter 5400 fits

The Equipter 5400 is a towable, self-propelled mobile crane. It tows behind a truck, unhitches, and drives to the setup point on wide tires designed to minimize ground disturbance. It lifts up to 4,431 lbs close in, reaches 23 feet, and lifts 893 lbs at full extension. The operator runs it by remote control and independent outriggers stabilize each lift.

That range suits many residential and light commercial jobs where the unit, the roof edge and the setup spot are close together. For heavier units or longer reaches, a larger crane is still the right tool; the load chart decides.

Safety and rigging checklist

• Qualified operator and rigger for the equipment and the lift.
• Load weight verified, not estimated.
• Lift planned at the actual reach against the load chart.
• Outriggers set on firm ground, with pads where needed.
• Tag lines to control the load.
• Clear drop zone; no one under a suspended load.
• Power-line clearance confirmed before the boom moves.
• Weather checked, especially wind for large, flat units.
