22-Ton or 40-Ton: How the Call Gets Made
In Short
The choice is never weight alone. It is weight plus horizontal distance plus room for the outriggers. Send those and the load chart answers it.

Choosing between the 22-ton and the 40-ton boom truck is never weight alone. It is weight, the horizontal distance from where the truck can safely sit to where the load must land, and how far the outriggers can extend. A light load far out can need the bigger truck. The load chart decides.
Weight Is Where the Question Starts, Not Where It Ends
Every customer opens with the weight, and the weight does matter. It is the first thing asked for and the thing most often wrong, because brochure figures are dry weight and the object in your driveway has fluids, fuel, sand or accessories in it that were added later.
But weight on its own answers almost nothing. A rated tonnage is what a machine can handle at its shortest working radius under good conditions, and that condition almost never describes a real job. The physics of how capacity falls away as the boom extends is covered properly on the capacity and reach page, and it is worth reading once. This page is about the practical decision that follows from it.
The short version: the same item can be an easy pick for the smaller truck in one yard and a job for the larger truck in the yard next door, purely because of where the truck is allowed to park.
Horizontal Distance Is Usually the Deciding Factor
The number that decides which truck comes is the horizontal distance from the center of the crane to the spot the load has to sit. Not the height. Not the frontage. The reach out across the ground.
Work an example in your head. A hot tub going into a backyard behind a single story house has to clear the roof, but more importantly it has to travel out past the depth of the house and then across the patio to its pad. Add those together and the number gets large quickly. Meanwhile a heavier item landing directly beside the truck barely stresses the machine at all. Light and far is harder than heavy and close, every time.
This is also why 142 feet of reach does not mean a load can be carried 142 feet away. That figure is the maximum the boom can extend. What can be lifted at any given extension is a much smaller and quite different question, and it is answered by the chart, not by the headline.
Setup Room Is the Third Leg
The third factor is how far the outriggers can extend once the truck is in position. A crane fully set up on all four corners is a much more capable machine than the same crane working with the outriggers pulled in on one side because a block wall is right there. Restricted setup narrows what can be done at every distance, which sometimes means bringing the larger truck for a load the smaller one could handle if it had room.
So the three inputs are weight, horizontal distance and setup room, and they interact. Change any one and the answer can flip. That is why an honest operator will not commit to a machine on a phone call that only mentions the weight.
The call itself gets made by reading the load chart for the exact configuration on the day: that truck, that boom length, that outrigger position, that radius, that rigging. The chart governs and it is not negotiable. Your job as the customer is much simpler. Supply the weight, supply the distance, and supply photos of the setup area, and the operator will tell you which truck is coming and why.
How the job runs
Our Process
Step 1: Get a real operating weight
Model number, manufacturer figure, fluids included, plus anything added since it was new. If it genuinely cannot be found, say so and the machine gets chosen with margin instead of assumption.
Step 2: Pace the distance from truck to landing spot
Stand where a truck could realistically park, walk to where the load must sit, and count your steps. A rough figure honestly obtained beats a precise figure invented.
Step 3: Photograph the setup area from both ends
One view from the truck position toward the landing spot, one looking back. Include the walls, the wires and the driveway. Those photos tell us how far the outriggers can go.
Step 4: Let the operator read the chart
With the weight, the radius and the setup constraints in hand, the chart for that exact configuration decides the machine. That is a judgment call made from the chart, not from a rule of thumb.
Scope
What Is Included
- A machine chosen from the chart for your actual configuration
- An operator who reads that chart for the day, not a generic answer
- Both the 22-ton and 40-ton boom trucks available for the job
- Rigging selected to suit the item and the radius
- A straight answer if the geometry does not work at all
Answers
Frequently Asked Questions
What is the real difference between the 22-ton and the 40-ton truck?
The larger machine carries more at any given distance and has more boom to work with, so it handles long reaches and restricted setups that the smaller one cannot. The smaller machine is easier to place in tight streets and yards, which sometimes matters more.
My item is light. Why would you bring the bigger crane?
Because of distance. If the truck has to sit well back from the landing spot, the boom is working far out, and capacity out there is a fraction of the rating. A light item at long radius can genuinely need the larger machine.
Can you tell me over the phone which crane will come?
Once you give the weight, the horizontal distance and a couple of photos of the setup area, usually yes. Without those, any answer would be a guess and we would rather not give you one.
Can you show me the load chart number for my lift?
The chart is read for the exact configuration on the day, including boom length, outrigger position and rigging weight. Quoting a figure out of context ahead of time would be misleading, so the operator makes that call on site.
What if the load turns out heavier than I said?
The pick stops and gets reassessed. Nothing gets attempted on the hope that the chart is generous. If the correct machine is a different one, we reschedule with the right truck rather than push a marginal lift.
