Spider Cranes and Mini Cranes in NYC: What Fits, What Lifts, Who Runs It
The number on a spider crane brochure is true. It’s just not the number you’ll get.
A spider crane sold as a “5,800 lb crane” lifts 5,800 pounds only a few feet from its own center. Reach out to where your load actually needs to land and the figure drops fast. Sometimes by more than half.
Rigging NYC runs spider crane and mini crane lifts for interior and tight-access jobs across New York City. This guide covers what spider cranes are, what they really lift, how they get into a building, and who is allowed to run one here. Then it covers what to send us so we can plan yours.
What a spider crane is, and what it is not
A spider crane is a small crane on rubber tracks with four fold-out legs. Those legs are the outriggers, and they’re where the name comes from.
Once they’re down, the crane sets a telescopic boom, turns a full 360 degrees and places the load by radio remote, with the operator standing where they can see it.
The point of the machine is access. It drives through a doorway, rides a freight elevator or walks down a hallway, then opens up into a real crane where the work is.
Spider crane, mini crane, mini crawler: one family
You’ll hear the same machine called a mini crane, a mini crawler crane, a compact crawler crane or a spyder crane. They mean the same thing. In plain terms it’s a compact crane on rubber tracks with legs, a mini crane on tracks, so you’ll also see it listed as a tracked spider crane.
SPYDERCRANE is a brand name: Furukawa UNIC machines sold in the US and Canada through Smiley Lifting Solutions. Maeda and Jekko build them too.
Sizes run a long way. The SPYDERCRANE lineup alone spans roughly 1,900 to 22,000 pounds of rated capacity across eight series. So “a mini crane” can mean a machine that fits in an elevator or one that needs a double door and a truck to get it to site.
Not a spider lift
This one trips people up all the time. A spider lift is an aerial work platform. It lifts people in a basket to work at height, like the atrium lifts on our rental fleet. A spider crane lifts loads on a hook.
Some spider cranes take a basket attachment for people, so you’ll see “spider crane with man basket” listed. That’s an add-on to a crane. If the job is people working overhead, ask for a lift. If it’s a load going up, over or in, you want the crane.
The mini cranes you’ll be offered in NYC
Ask around for a small crane in this city and you’ll get four different cranes pitched as the answer. They’re not interchangeable. Here’s how they compare.
| Machine | How it works | Typical width | Best NYC use | What limits it |
|---|---|---|---|---|
| Spider crane (mini crawler crane) | Tracks to travel, four outriggers to lift, 360° boom | About 24 in on the small models; 51 to 66 in on the bigger ones | Interiors, roofs, atriums, courtyards, glass | Capacity falls fast with radius and with short outriggers |
| Electric pick-and-carry crane | Wheels; picks the load and drives with it, usually without outriggers | About 34 to 38 in | Moving glass, panels and equipment along a floor | Short reach and low hook height |
| Carry deck crane | Wheeled crane with its own deck to carry material | About 5 ft on a 4 ton unit | Plants, garages, yards, big open floors | Too wide and heavy for most building interiors |
| Boom truck | Crane on a truck chassis, set up at the curb | A full truck | Street-side picks to a roof or a window | Needs the street, and can’t go inside |
We carry the middle two on our own fleet. Our electric crane line is the pick and carry crane type that some rental houses sell as a walk behind crane.
Those cranes, from Bailey, Jekko and JMG, run 34.5 to 37.4 inches wide and are rated from 1,950 up to 5,500 pounds depending on the model and setup. Our carry deck cranes come in 4, 9 and 15 ton sizes. You can see them in our cranes category.
When the pick is from the street, a boom truck is often the simpler answer. A spider crane earns its place when the load has to be lifted somewhere a truck can’t reach.
Capacity at radius: the number that decides the machine
Every crane is rated by how much it lifts at a given distance from its center of rotation. That distance is the radius. A spider crane’s headline capacity applies only at the shortest radius on its chart.
Here’s a real one. The SPYDERCRANE spec sheet for the URW205 lists a maximum of 5,800 pounds. This is what its load chart shows with the outriggers fully extended:
| Working radius | Rated load, outriggers fully out | Rated load, outriggers not extended |
|---|---|---|
| 3 to 5 ft | 5,800 lb | 4,450 lb |
| 6 ft | 4,950 lb | 3,150 lb |
| 8 ft | 3,800 lb | 1,600 lb |
| 10 ft | 2,850 lb | 1,100 lb |
| 12.6 ft | 2,000 lb | 600 lb |
| 27.6 ft (full boom) | 350 lb | 130 lb |
Read that 10 foot row again. At ten feet out, a 5,800 pound crane is rated for 2,850 pounds. At full reach, 350. That’s a different machine from the one on the brochure.
So when you size a spider crane, start with two numbers: the weight of the load, including the rigging, and the radius from where the crane can actually sit to where the load lands. Then read the chart. The headline figure is only useful for knowing which family to look at.
How to read a spider crane load chart
A spider crane load chart has more moving parts than a mobile crane brochure suggests. On the URW205 sheet there are separate tables for each boom stage, for the jib, and for the two outrigger states. You pick the table that matches how the crane will actually be set, then read across to your radius.
A few habits keep you out of trouble. Count the rigging as part of the load, because slings, shackles and a vacuum lifter all hang below the hook. Read the radius at the farthest point the load travels, not where it starts. And if the radius falls between two columns, use the longer one.
That’s also why comparing spider crane specs by headline number doesn’t work. Two spider cranes with the same maximum can have very different spider crane capacity at 15 or 20 feet. Ask for the chart, not the brochure.
When Rigging NYC plans a spider crane lift, this is the first thing we check against your load: the chart for the setup the room allows, at the radius the crane can really work.
Why the outriggers change the chart
Look at the right-hand column. Same crane, same 10 foot radius, but with the outriggers not extended it’s rated for 1,100 pounds. That’s less than 40 percent of the full-spread figure.
Indoors, that’s a real risk. A hallway, a balcony, a column line or the edge of a slab can stop one or two legs from opening fully.
The crane’s stability system then holds it to the smaller chart, or to a narrower safe working area. Planning for full outriggers and arriving to find you can’t spread them is how a lift day turns into a lost day.
Getting a spider crane into a New York building
Before anyone talks capacity, the crane has to get to the pick. In this city the route is usually the hard part.
Doors and freight elevators
Travel width is the first fit number, and it’s where a small spider crane earns its name. On SPYDERCRANE’s published specs:
- URW094: 23.6 inches wide and about 2,400 pounds. SPYDERCRANE calls it the elevator model and says it fits in a standard elevator.
- URW205 and URW295: 24 inches wide, and about 4,330 pounds on the URW205’s sheet. A single door.
- 300 series: 51 inches wide and about 8,700 pounds, so you need a double door.
- 500 series: 54 inches wide and about 11,000 pounds.
Rigging NYC asks for the route before it picks the machine, because the route usually decides it. Measure the clear opening, with the door fully open, not the size printed on the door.
Then check the freight elevator twice: the car and door dimensions, and the rated capacity. A 24 inch crane that fits the cab is still no good if it’s heavier than the elevator is rated for.
Floors, slabs and outrigger pads
Once it’s set up, the crane’s whole weight plus the load goes down through four outrigger pads. On a URW205 lifting its full rated load, that’s over 10,000 pounds on four small footprints. And when the boom is over one leg, that leg carries far more than its share.
A slab on grade is the simple case. On an old wood floor, a slab over a cellar or a raised floor, it’s the question the building engineer will ask.
Mats spread each pad’s load, and that’s what makes it something an engineer can check. They don’t add capacity to a floor that doesn’t have it. So get the outrigger loads for your actual setup and hand them to whoever signs off on the floor. Not the crane’s total weight. The load at each pad.
On the lifts we run, the pad layout and how the load gets spread is part of the plan. The building’s engineer signs off on what the floor can take.
Finished floors are the other worry. Indoors, the usual damage isn’t a collapse. It’s a dented, scratched or cracked finish, and you can’t undo it. Floor protection belongs along the whole route and under every set position, because a spider crane crawls and re-sets between picks.
And one simple check: mats under every outrigger, every time the crane sets up. Missing mats or cribbing is the usual cause of outrigger accidents, and the trade press has said so for years.
Footprint matters too. The URW205’s sheet shows about 12.5 to 13 feet each way with the outriggers fully out, and roughly 8.5 by 7.5 feet at its tightest setup.
Indoor power
The standard engines are gas, propane or diesel. Inside an occupied building, a data center or a finished lobby, that may not be allowed. Many models come with battery or electric options instead. SPYDERCRANE’s URW094 is battery only and plugs into a standard 110 volt outlet to lift.
Tell us early if the building has rules on fumes or noise, or if the space stays open to the public while we work. It changes which crane we bring and when we lift.
Where spider and mini cranes earn their keep in NYC
Glass is a big one. Pair a spider crane with a glass manipulator or a glass vacuum lifter and you can set curtain wall panels, storefront glass and big interior partitions where a bigger crane can’t reach. SPYDERCRANE says its 200 series is quickly becoming one of the most in-demand glazing tools.
On a glazing job, the glass spider crane is the glass lifting crane, and the manipulator or vacuum lifter is the tool on its hook. We rent glass manipulators from 700 to 2,800 pounds and run the full lift through our glass and architectural rigging work.
Then there’s everything that has to go up, in or across, with no street access:
- Rooftop units and equipment moved and set on the roof itself, once the crane is up there.
- Mechanical rooms and basements, where the crane comes down a ramp or rides the elevator.
- Atriums and lobbies, for art, signage, steel or stairs.
- Rear yards behind brownstones and row houses, where a mini crane for construction work has to come in through an alley or a narrow side passage.
- Steel and stair sets on upper floors of a building that’s already closed in.
One NYC detail worth knowing: SPYDERCRANE lists the URW205 as a variant “configured and certified for use in New York City.” Which model suits your job still depends on the chart, the route and the floor.
Who is allowed to run it: NYC license and rigging rules
This is where a lot of out-of-town rental advice falls apart.
Since November 7, 2024, operating a mini crane in New York City requires a hoisting machine operator license issued by the Department of Buildings.
DOB created a limited license class for mini cranes, alongside classes for articulating boom cranes and rotating telehandlers. Anyone who applied on or after that date can’t operate until the license is actually issued.
The license is only half of it. Lifting or lowering a suspended load in the city needs supervision by a licensed rigger or a competent rigging supervisor, and that still applies when the machine itself needs no permit.
A DOB exemption doesn’t cover the street either. If any part of the job touches the sidewalk or the roadway, the city’s Department of Transportation has its own requirements.
Our guide to which NYC crane permit a lift needs goes through the permit side. On our own lifts it’s simple: Rigging NYC Contractors is run by licensed master riggers, and our owner, Daniel Berkman, holds NYC Master Rigger license #214. The master rigger page covers what that supervision includes.
Spider crane rental in NYC, or an operated lift?
Most people start by searching “spider crane rental NYC” or “mini crane rental.” Elsewhere it’s called spider crane hire or mini crane hire. Starting there makes sense, and for some crews renting is the right call.
If you already have an operator with the DOB mini crane license, a rigging supervisor and a lift plan, a bare rental can work.
For everyone else, the operated lift is the easier path. Rigging NYC provides spider crane and mini crane lifts with the crane, a licensed operator, the rigging crew, the lift plan, the permits and the trucking.
You don’t hunt for an operator who holds the right license class, and you don’t find out on the day that the outriggers won’t spread.
It’s also how the risk sits with the people who know the machine. Read the chart wrong on a small crane and the load moment system stops you, if you’re lucky. On a finished floor, the unlucky version is expensive.
So if you’ve been searching for small crane rental, a mini crawler crane rental or indoor crane rental for a single job, send us the pick first. We’ll tell you which machine fits, and whether you need the crane, the crew or both. You can also see our wider NYC crane services.
What drives the cost of a spider crane lift
We don’t publish prices, because two lifts with the same crane can cost very different amounts. A spider crane price you see online is often for the machine alone, and spider crane rental cost on its own says little about what the lift will cost. These are the things that move the number:
- The capacity class you need at your radius. A long reach can push you up a size even for a light load.
- Time on site. That includes setup, the lift window the building allows, and any standby for wind or deliveries.
- Access work, like floor protection, mats and cribbing, elevator reservations and how far the crane has to walk.
- Power type, if the building needs battery or electric.
- Trucking and the delivery window, especially in Manhattan.
- Whether the lift needs engineering or a permit filing.
Our crane rental cost guide goes through how NYC crane jobs are priced in more detail.
What to send us for a quote
A good quote comes from good inputs. Send these and we can usually tell you the machine and the plan in one go:
- The load: weight, size and how it’s picked. A photo of the plate or the spec sheet helps.
- Where it starts and where it has to land.
- Where the crane could sit, so we can work out the radius.
- The route in: the narrowest door, any steps or ramps, and the freight elevator’s size and rated capacity.
- The floor or slab it will sit on, and whether there’s a cellar under it.
- Indoor or outdoor, and what power is on site.
- Your dates, and the building’s rules on hours, noise and fumes.
For bigger crane jobs, our page on what to have ready before you book a crane lift covers the rest.
Spider and mini crane FAQ
What is a spider crane used for?
Lifting loads where a normal crane can’t get to. Glass and curtain wall panels, rooftop and mechanical equipment, steel and stairs inside buildings, atriums, basements and rear yards. It drives in on tracks, sets four outriggers and lifts like a full crane.
How much can a spider crane lift?
It depends on the model and, more than anything, the radius. The range runs from about 1,900 pounds to about 22,000 on the SPYDERCRANE lineup. A URW205 is rated for 5,800 pounds close in, 2,850 at 10 feet and 350 at full reach, with the outriggers fully out.
How much does a spider crane weigh?
Spider crane weight runs from about 2,400 to 4,400 pounds on the small models. SPYDERCRANE lists the URW094 at about 2,400 and the URW205 at about 4,330. The 300 series is around 8,700 pounds and the 500 series around 11,000.
What is the smallest spider crane?
On the SPYDERCRANE lineup, the smallest crane is the URW094. It’s 23.6 inches wide, about 2,400 pounds, rated up to 1,990 pounds, with an 18 foot boom. It runs on battery, plugs into a 110 volt outlet to lift, and SPYDERCRANE says it fits in a standard elevator.
Will a spider crane fit in a freight elevator?
The smallest ones can. SPYDERCRANE’s URW094 is 23.6 inches wide and is sold as fitting a standard elevator. Check the car size and the elevator’s rated capacity against the crane’s weight before you book, not just the door.
Do I need a license to operate a mini crane in NYC?
Yes. Since November 7, 2024, the Department of Buildings requires a hoisting machine operator license to operate a mini crane, with a limited license class for mini cranes. A licensed rigger or competent rigging supervisor also has to supervise the lift.
What is the difference between a spider crane and a spider lift?
A spider crane lifts loads on a hook. A spider lift lifts people in a basket so they can work at height. They look alike because both sit on tracks with fold-out legs.
How much does a spider crane cost?
It depends on the capacity you need at your radius, the time on site, the access work, the power type and the trucking. Send us the load, the route and the building rules and we’ll price the lift.
Send us the pick
The right spider crane is the one that gets through your door, sits safely on your floor and lifts your load at your radius, run by someone the city allows to run it. Get those four right and the lift itself is the easy part.
Rigging NYC Contractors plans and runs spider and mini crane lifts across Manhattan, Brooklyn, Queens, the Bronx and Staten Island. Call us at 347-447-2987, or send the load, the route and a few photos and we’ll come back with the machine and the plan.
