Loads that need real rigging thought
Utility transformers and electrical equipment often have an off-center weight and lifting points built into the frame that have to be used correctly. Long items like trusses, pipe, or structural steel need spreader bars or a multi-point pick so the load does not bend or swing.
Setting equipment into a tight mechanical room, a rooftop curb, or between existing structures takes more than lift capacity, it takes an operator and rigger who can talk through the exact final placement before anything leaves the ground.
Transformers and utility equipment
A common job we see: lifting utility transformer components in the 500 to 10,000 pound range, with item lengths around 20 to 30 feet, off a trailer and onto a concrete pad or structure. These jobs usually run multiple days and need a crew that understands the lifting points built into the equipment, not just raw capacity.
If this sounds like your job, say so when you request a quote and ask specifically whether the company has rigged transformers before.

Size my liftWhat to tell the rigging crew
Where the designed lifting points are (if the equipment has them), the exact finished location including height and clearance, and any obstacles between the pick and the set, doorways, overhead lines, other equipment already in place. The more specific you are, the fewer surprises on site day.
Trusses and structural steel
Roof trusses and structural steel pieces are long and can sag or twist if lifted from the wrong points, so most rigging crews use multiple pick points or a spreader bar to keep the load stable in the air. On a residential or small commercial roof job, this also means the crew needs enough room below the lift path to set each piece down safely, not just room for the crane itself.
If your job involves setting multiple trusses or steel pieces in sequence, tell the rigging crew the order you want them placed in. Planning that ahead of time instead of figuring it out piece by piece saves real time on site.
When to ask for a rigging specialist
Most operated crane rentals come with a rigger who can handle common loads without any extra planning. But a few situations call for someone with more specific rigging experience: equipment with an unknown or undocumented weight distribution, loads that have to be rotated or flipped during the lift, or a pick where the lifting points are not obvious from looking at the equipment.
If your job sounds like one of these, say so when you request a quote. It is better to ask for a specialist upfront than to have a standard crew arrive and discover the load needs more planning than expected.
Questions
Is rigging included with a crane rental?
Basic rigging for common loads is usually included with an operated rental. Unusual shapes, long items, or equipment with specific lifting points may need extra planning or a specialized rigger, ask up front.
Who figures out the center of gravity on an odd-shaped load?
The rigger and operator do, usually from the equipment's data plate or drawings if available. If the load's weight distribution is unknown, tell them before the lift, not during it.
Can you set equipment inside a building or mechanical room?
Depends on the access and the equipment size. Describe the opening size, the path, and any tight turns when you request a quote so the company can tell you what will and will not fit.
