Operator & rigging included · Bare rental also available
The Grove GMK5120B is a 120-ton all-terrain crane available with a certified operator in Phoenix, Arizona. ON-SITE runs a 2001 unit from its yard at 21815 N 16th St, the largest mobile crane in the fleet. It dispatches with a counterweight support truck and lowboy, quoted as their own separate lines.
A name and a number is all it takes. We call back with the quote, usually same day.

All-terrain carrier
A 120-ton rating is the number at the crane's shortest working radius, not the number at your load. What matters on your job is what the crane can pick at the distance it actually has to reach, and that falls away fast as the boom goes out. Two loads of the same weight can need very different machines because one of them sits 40 feet further from the crane.
In practice this is the machine we send when the pick is too heavy or too far out for a rough terrain, or when the load has to go up and over something. Tall structural steel sets, tank and vessel placement, long-radius picks over an existing building, and mechanical work where the crane cannot get close to the load.
Tell us the weight, the radius and what the ground under the outriggers looks like, and we will size it. If the 80-ton rough terrain does the job for less mobilization, we will tell you that instead.
What we can confirm about the actual unit in our yard. We do not publish numbers we have not verified off the machine.
One 120-ton all-terrain in the fleet, and the big classes book out first. The earlier you give us the date, the better the odds we can hold it for you.
| Spec | Detail | What it means for your job |
|---|---|---|
| Make and model | Grove GMK5120B | The model number is what the load chart and spec sheet are issued against |
| Rated capacity | 120 ton | Maximum rating at minimum radius. Capacity at your radius comes off the chart |
| Crane type | All-terrain | Multi-axle carrier that travels the highway and still handles a rough site |
| Model year | 2001 | The year of the unit that will show up, not a class average |
| Units in fleet | 1 | Owned and parked at the 16th Street yard, not brokered from another yard |
| Rental type | Operated | Operator, rigging and lift plan included. Bare available if you have your own certified operator |
| Load chart | With quote | Issued for this unit and your configuration when we quote the lift |
The support truck and lowboy that travel with this crane are covered below. They are mandatory on a machine this size and they are quoted as their own itemised lines rather than folded into the crane rate.
We publish only what we can stand behind. Boom and jib lengths, dimensions, weights and the load chart come with the quote, off the sheet for the actual unit in our yard rather than a number copied from a spec site for a different build of the same model.
10%
Whatever you are paying for an equivalent 120-ton class crane today, we go 10% under it going forward. Not an introductory rate that quietly resets after the first job. Send the invoice, or just describe the work and we will quote it against the market and apply the discount anyway.
There is no rate card on this page on purpose. Every job gets quoted for what it actually is.

This is the one thing to understand before you compare quotes on a crane this size.
The counterweight travels separately
A machine in this class cannot carry its full counterweight down the road with it. A support truck brings it, and it is not optional.
The lowboy goes with it
Getting the crane and its counterweight to your site is a haul job in its own right, and we do it on our own lowboys rather than booking a third party.
Separate itemised lines, always
The crane, the support truck and the lowboy appear as three visible lines on your quote. We do not roll them into one flat number.
That is not an upsell
Anyone quoting a 120-ton flat with nothing beside it has either buried the support cost inside the rate or has not accounted for it yet.
Setup time is real
Rigging the counterweight on and off is part of the day. It is better to see that on the quote than to discover it on the invoice.
Still no counterweight fee
To be clear: we do not add a separate counterweight fee on top. The support truck and lowboy are haul and equipment lines you can check.
You are hiring a lift, not a machine. The pieces that normally get sourced separately arrive as one line of responsibility.
A certified operator
Confirmed before the crane moves. You are not sourcing one per job.
Rigging for the pick
Blocks, spreader bar, slings and crane mats as the lift actually needs.
The lift plan drawn
For your load, your radius and your ground, not a generic load chart.
COI verified before release
Insurance is checked on our side, every job, before iron leaves the yard.
Delivered on our own trucks
Tri-axle tractors, lowboys to 75 ton and a 53 ft flatbed. The haul is ours.
Photo walk-around
Condition recorded at drop and pick-up, so damage never becomes a dispute.
Three different answers to "the load is heavy", and they cost and mobilize very differently.
Rough terrain, 50 to 80 ton
All-terrain, 120 ton
Lattice crawler, 100 ton
Operated crane work bills against an hourly minimum, portal to portal. The clock runs from our yard and back rather than only while the crane sits on your pad, which is standard for operated service and is the number people forget to compare when they shop a rate.
A rigger or signal person is added per man when the pick calls for one. There is no fuel surcharge and no counterweight fee. Larger jobs are quoted as clean separate lines so mobilization, setup and crane time are each visible instead of rolled into one figure you cannot check.
On this class specifically, the support truck and the lowboy are separate itemised lines on the quote. That is deliberate. You should be able to see exactly what the crane costs, what the counterweight move costs and what the haul costs, rather than reading one number and hoping.
We quote per job rather than publishing a rate, because the same crane costs very differently on two jobs. These are the variables that actually move the number, so you can sanity-check any quote you get, including ours.
Radius and configuration
How far out the load sits decides how much boom, counterweight and setup the pick needs. It is the biggest driver after capacity.
Time on the clock
Operated work bills portal to portal against an hourly minimum, so travel from the north Phoenix yard counts.
Mobilization
Distance from the yard, plus the support truck and the lowboy that move the counterweight. Three lines, all visible.
Assembly and teardown
Rigging counterweight on and off at both ends is part of the day on a machine this size.
Ground and access
Bearing capacity, outrigger pads, crane mats and how the crane gets onto the site all change setup time.
Permits and closures
Street or lane closure work adds coordination, and it belongs on the quote rather than appearing as a surprise.
10%
Send us the invoice you pay today for an equivalent crane and we will go 10% under it going forward.
Beat my rateThe yard is at 21815 N 16th St in north Phoenix. The move is quoted from there, so the closer the job sits to the North Valley, the shorter and cheaper the haul.
Most of our crane work is metro Phoenix, where the move is short and same day is often possible. For jobs that justify the mobilization we run the 120-ton statewide across Arizona, and out of state when the project warrants it.
Metro cities we run to most
If the crane you were counting on goes down mid-pour, mid-set or mid-schedule, we run a replacement out of whatever is available in the yard rather than telling you to move the date. Dispatch starts at 4:30am, six days a week, and emergency work goes to the front of the queue.
Everything here is owned and parked on 16th Street in north Phoenix. Swipe through, or open any machine for its page.
