A tight Sydney site can make a city crane look like the obvious choice. The machine is compact, manoeuvrable and designed to work where streets, buildings and setup areas leave little room to spare. The crane still needs enough capacity and reach once it reaches the working position.
Load weight, lift radius, required height, ground conditions and the route into site can all change the crane selection. A city crane may fit the work zone neatly, so capacity at the required radius still needs to be confirmed. An all terrain crane can provide additional reach and lifting performance when the lift requires it.
City Crane Vs All Terrain Crane: The Practical Difference
City cranes and all terrain cranes are both mobile lifting options. The difference shows up in the space, capacity and reach available on site. AOR Cranes’ city crane range covers 13 to 20 tonne machines built around compact access and confined working areas. The all terrain fleet runs from 40 to 100 tonnes, adding greater lifting capacity and boom reach for more demanding work.
Some all terrain cranes are built for restricted urban work. AOR’s 50 tonne Liebherr LTC combines higher lifting capacity with dimensions suited to confined sites.
| Site consideration | City Crane | All Terrain Crane |
|---|---|---|
| AOR fleet capacity | 13 to 20 tonnes | 40 to 100 tonnes |
| Operating footprint | Compact | Generally larger |
| Restricted urban access | Strong fit | Model and site dependent |
| Capacity and reach | Lower capacity and shorter reach | Higher capacity and greater reach |
| Best fit | Compact urban lifting | Heavier or longer-radius lifting |
How To Decide Between A City Crane & An All Terrain Crane
Site Access & Crane Footprint
Urban crane selection usually starts with physical space. The crane has to reach its working position, turn where required and leave enough room for outriggers, rigging and the people controlling the lift.
Check the full approach and the final crane position:
- Street and driveway width
- Gate or laneway clearance
- Turning space and tight corners
- Available outrigger area
- Scaffold, hoarding and neighbouring structures
- Trees, powerlines and other overhead obstructions
- Traffic lanes, loading zones and parked vehicles
This is where a city crane can have a clear advantage. Its compact footprint and short turning radius can make a difficult urban setup workable. The access check also needs to include the lift position. The crane needs to reach the setup area and stand close enough to the load and landing point for the planned radius.
Load Weight, Radius & Height
Crane capacity changes with the working radius, boom configuration and lift conditions. The rated capacity shown in a crane’s name describes the upper end of what that model can lift under specific conditions, so the available capacity at the hook needs to be checked for the planned lift.
For crane selection, the team needs to understand:
- The weight and dimensions of the load
- Where the load will be picked up
- Where it needs to land
- The horizontal distance from the crane to those points
- The height and clearance required through the lift
Those numbers quickly show which crane sizes can complete the lift. A 13 or 20 tonne city crane may suit the available space, with the planned radius determining whether its load chart provides enough capacity. A larger all terrain crane can provide additional capacity or reach and can still be planned around an urban site.
Capacity at the planned radius is the figure that matters on lift day.
Road Access & Mobilisation
On an urban job, crane planning starts before the machine reaches the gate. Sydney streets can bring narrow approaches, clearways, parked cars, low branches, traffic controls and restricted places to stop or set up.
The size and configuration of the crane also affect how it can travel on the road network. Depending on the crane and route, access may be covered by a heavy vehicle notice or require a permit, with conditions that need to be checked before mobilisation. Larger all terrain cranes can require closer attention to approved access, dimensions and the route to site.
Street photos, site access notes and the proposed crane position give the hire team a useful starting point. Where traffic control, permits or other access arrangements are required, they can be identified before crane day.
Setup Area & Ground Conditions
A smaller crane footprint helps when space is limited. Every outrigger-supported crane still needs a suitable standing area. The setup has to support the crane through the planned lift without relying on weak edges, uncertain fill or ground that has changed since the site was inspected.
Look closely at:
- Soft verges and road shoulders
- Recently backfilled trenches
- Underground services and pits
- Sloping or uneven surfaces
- Excavations close to the setup area
- Suspended slabs or podiums where structural capacity needs checking
The setup position can also affect crane choice. A machine that has to stand farther from the load because of site constraints works at a greater radius, which can reduce the capacity available at the hook. Compact access matters when it puts the crane in a better lifting position.
Which Crane Fits The Job?
Choose A City Crane When Space Is The Main Constraint
A city crane is a strong option when access and setup space are the main challenges and the planned load stays within the crane’s rated capacity at the required radius.
That can suit steel installation, rooftop equipment and other urban lifts where the crane needs to work from a compact position on a narrow street or in a confined work zone.
AOR’s City Crane Hire Sydney range includes 13 and 20 tonne options. When the load, radius and height sit within the crane’s limits, a city crane can keep the setup compact.
Choose An All Terrain Crane When Capacity Or Reach Drives The Lift
An all terrain crane becomes the stronger option when the lift needs more capacity, a longer working radius or greater boom reach. AOR’s All Terrain Crane Hire Sydney fleet runs from 40 to 100 tonnes, covering compact urban work through to larger commercial and infrastructure lifts.
AOR’s all terrain fleet also includes models built for confined urban work. The 40 tonne Liebherr LTM 1040-2.1 is positioned for tight sites. The 50 tonne Liebherr LTC 1050-3.1 is designed for confined urban spaces. These models give AOR higher-capacity options for restricted sites when the lift requirements exceed the city crane range.
What If The Load Needs To Move Around The Site?
City cranes and all terrain cranes are generally selected here for lifts completed from a planned, outrigger-supported setup. If the job calls for picking up a load and carrying it around the site, a pick and carry crane may suit the work better. AOR’s Franna Crane Vs City Crane guide explains how those two approaches differ.
Plan The Crane Around The Site Before Mobilisation
The crane choice gets easier once the site information is clear. Before booking, give the AOR team enough detail to understand both the lift and the space around it.
Useful information includes:
- Load weight and dimensions
- Pick and landing positions
- Required height or radius where known
- Site address and proposed crane position
- Street, driveway and access photos
- Setup area and ground conditions
- Site plans or drawings where relevant
- Known traffic, parking or access restrictions
A few accurate measurements and photos can rule out unsuitable options before mobilisation. They also give the crane team time to identify access, setup or traffic issues before the lift is locked in.
Plan Your Urban Lift With AOR Cranes
The right crane choice starts with the load, radius, access and setup area. Getting those details clear early helps AOR Cranes plan a workable crane position, confirm the required lifting capacity and identify access issues before mobilisation.

City Crane Vs All Terrain Crane FAQ
Is A City Crane Better For Tight Sydney Sites?
A city crane is often a strong choice when street access, turning room or setup space is restricted. The final selection also needs to confirm enough capacity and reach for the load at the required radius.
Can An All Terrain Crane Work On A Tight Urban Site?
Yes. All terrain cranes vary considerably in size and configuration. AOR’s fleet includes compact Liebherr models designed for tight or confined work, including the 40 tonne LTM 1040-2.1 and 50 tonne LTC 1050-3.1. Site access, outrigger space and lift requirements still need to be checked before mobilisation.
Which Can Lift More, A City Crane Or An All Terrain Crane?
Across AOR’s current fleet, all terrain cranes provide the higher nominal capacities, ranging from 40 to 100 tonnes compared with 13 to 20 tonnes for city cranes. Actual lifting capacity depends on the model, working radius, boom configuration and lift setup. Use the rated crane size alongside those lift conditions when selecting the crane.
What Information Does AOR Need To Choose The Right Crane?
Start with the load weight and dimensions, pick and landing locations, site address, access photos and any known height, radius, ground or traffic constraints. Plans or drawings can also help on more complex lifts. With those details, the team can assess which crane class suits the site before the booking is locked in.
