Compact by design. Capable by nature
Potain's self-erecting technology is built around one idea: get the crane up fast, lift what the job needs, and get out just as quickly.
Engineered for tight, high-turnover sites, Potain self-erecting tower cranes deliver quick set-up, confident remote operation, and easy transport between jobs.
Each model in this range is built to cover a different site challenge, but they share the same core advantages: compact transport format, autonomous erection, wireless remote control, and electric power.
For contractors juggling multiple builds in urban areas, these are the machines that keep pace with a fast-moving workbook without tying up a crane crew between jobs.
-
Self-Erecting Mechanism
Conventional tower crane assembly ties up a crew for the better part of a day. The Potain self-erecting mechanism changes that equation.
A single operator can take the crane from transport to first lift in hours, using the Smart Set-up screen to guide each stage of erection.
The time saving compounds across every move in the crane's working life. -
Compact Transport Format
Moving a conventional tower crane between sites means cranes, low-loaders, and days of logistics.
The Potain self-erecting range folds down into a road-legal transport format.
Combined with TRT's purpose-built IGO trailer, the whole package moves quickly and cleanly, keeping relocation costs predictable. -
Smart Set-up Software
Smart Set-up guides the operator through every stage of erection and folding with clear, step-by-step instructions on the control screen.
It removes reliance on memory, reduces the risk of erection sequence errors, and means an operator new to the machine can run it safely from day one. -
Wireless Remote Control
The wireless remote puts the operator where the job needs them, not where the crane puts them.
Full machine control at distance means better load visibility, faster reaction to site conditions, and no cab access required.
For inner-city sites with restricted working space, it is a practical advantage on every shift. -
Variable Frequency Motor Drives
Electric motors with variable frequency drives give smooth, controlled lift and slew without the power surges that cause load swing on less sophisticated machines.
The result is more precise load placement, less wear on the crane's mechanical components, and quieter operation for noise-restricted urban sites. -
CraneSTAR Diag Remote Diagnostics
The Hup M 28-22 includes CraneSTAR Diag, a remote diagnostic system that gives service technicians access to crane data without needing to be on site.
A fault can be identified, parts can be ordered, and a fix can be planned before anyone leaves the depot. Less diagnostic guesswork means faster return to service.
Range options that match your site, reach and lift plan.
Choose a self-erecting crane by what matters on the job: capacity where you lift most, radius to cover your workface, and hook height to clear obstacles—without overcapitalising on crane you don’t need.
Across the HUP and IGO models, you’ll find compact transport formats, practical working radii, and lift capacities suited to high-density residential and smaller construction sites—supported by TRT’s parts and service network.

Frequently Asked Questions
-
What is a self-erecting tower crane, and when would I use one instead of a mobile crane?
A self-erecting tower crane folds out from a transport configuration into a working crane without any outside assistance. No assist crane, no large crew, no extensive ground preparation before lifting begins.
They are the practical choice for urban residential construction, high-density sites, and projects where space is tight and the crane needs to move between locations regularly. A mobile crane on the same site would require more room, more setup time, and more people.
If the job is multi-storey residential in a confined street or subdivision, a self-erecting tower crane is usually the faster and cheaper way to put steel in the air.
-
Do I need another crane on site to erect a Potain self-erecting crane?
No. Every model in the Potain self-erecting range unfolds and erects autonomously. The HUP models use Smart Set-up software that guides the operator through erection step by step, with instructions displayed on the control screen.
The IGO MA21 operates within a 3.6 m x 3.6 m footprint and erects without any external assist. The HUP 40-30 includes movement technology specifically designed to allow unfolding in narrow and compact areas.
For smaller builders and rental operators, that self-sufficiency is the point. You are not paying for a second crane every time the job moves.
-
How much space does a Potain self-erecting crane need on site?
It depends on the model, but the range is specifically designed around compact urban sites. The IGO MA21 works within a 3.6 m x 3.6 m footprint with an adjustable-spread chassis that gives you three operational jib configurations to suit the layout.
The HUP 40-30 uses movement technology that enables unfolding in narrow and compact areas where a conventional tower crane couldn't be positioned.
Hook heights per base range from 3 m on the IGO MA21 up to 30 m on the Hup M 28-22, so there is a model sized to the site rather than the other way around.
-
What jib lengths and lift capacities does the range cover?
The range spans from the IGO MA21 at 1.8 t maximum capacity and 26 m operating radius, up to the Hup M 28-22 and Hup 32-27 both rated to 4 t with operating radii of 40 m and 32 m respectively. The HUP 40-30 sits at 2.2 t capacity with a 28 m operating radius.
Tip capacities run from 0.7 t on the smaller models to 1 t on the HUP 32-27 and Hup M 28-22.
For multi-storey residential work, most jobs in this segment fall within what these models cover. If your lift requirements push beyond the self-erecting range, the TRT crane team can advise on the next step up into the Potain top-slewing range.
-
Can these cranes be operated remotely?
Yes. Wireless remote control is standard across the Potain self-erecting range. The IGO MA21 and HUP models both include advanced remote control capability that gives the operator flexibility to position themselves where visibility is best, rather than being fixed to a cab.
The HUP 40-30 is noted for its remote control capabilities specifically within urban construction environments, where the operator often needs to manage lifts from multiple vantage points across a confined site.
For residential builders working without a dedicated crane operator in the cab, that flexibility changes how the day runs.
-
How do I transport a Potain self-erecting crane between jobs?
The self-erecting range folds down into a compact transport configuration, which is a core part of the design. The Hup M 28-22 is specifically described as the only self-erecting crane with a 28 m jib available in such a compact transport format.
For the IGO MA21, TRT manufactures a dedicated crane trailer purpose-built for easy and efficient transport of that model between sites. It is available directly through TRT alongside the crane.
For operations moving a crane frequently across a subdivision or between multiple short-duration jobs, the transport configuration matters as much as the lifting specs.
-
What service and diagnostic support is available after purchase?
The Hup M 28-22 includes CraneSTAR Diag, Potain's remote diagnostic tool, which allows maintenance issues to be identified without a technician physically attending the machine. That reduces downtime and speeds up resolution on a working site.
TRT backs all Potain cranes with the same crane service network that supports Manitowoc equipment across New Zealand and Australia, including parts availability and field service.
For smaller builders who don't have in-house crane technicians, knowing that support is a call away is part of the ownership equation. Contact TRT to discuss a maintenance plan suited to your fleet and project calendar.
