Self-Erecting Tower Cranes Vs. Boom Truck

In our earlier posts, we touched base on the advantage of using self-erecting tower cranes over telehandlers and mobile cranes. Today, we discuss again the benefits of using self-erecting tower cranes for low rise building. NFT has supplied over hundreds of self erection cranes in the GCC over the past year and continues to promote its cost saving and increase capacity over other cranes. Today, NFT has 40 self erecting tower cranes in its fleet, ranging from 1 to 10 Tonnes.

Increased Efficiency

Efficiency when using self-erecting tower cranes is improve by:

  • Reducing number of framers required
  • Eliminating need for rough terrain forklifts and tow motors
  • Eliminating need for hydraulic crane for truss work
  • Reducing the number of laborers handling materials
  • Working on tighter job sites
  • Eliminating a pump truck for columns, footings, and walls
  • Saving time with quick and easy set-up

Self-erecting tower cranes set up so quickly compared to conventional tower cranes. These get on-site and in operation in less than two days.

Remote Control Operation

The remote control operation of these cranes is awesome, it allows to operate more efficiently and with less personnel.  The crane operator can rig several panels himself, pick and move them and unload in steps. NFT operators are  very efficient and experienced in driving self-erecting cranes.

The Future is Here: Self-Propelled Self-Erecting Tower Cranes

The Potain IGO MA21 mounted on a 4WD chassis that runs off of its own generator. Users can maneuver around the job site with 4-wheel drive and 4-wheel steer capabilities all while the tower remains set-up. No more setting up with a truck and trailer.

  • Driving and steering via tethered control unit with push buttons
  • Electro-mechanical four-wheel drive with 2 speeds and four-wheel steer
  • Can be driven fully erected (on flat, with no load)
  • Heavy duty axles with planetary hub reduction and dual 9.00 x 20 off-road tires
  • Four extendable hydraulic outriggers with a base of 13.1 x 13.1 ft.
  • Power supply: Onboard 23kVA soundproof genset, or customer supplied 480 V “city power”
  • Transport dimensions: (l x w x h) 39.6 by 9.1 by 10.1 ft., total weight 49,384 lb.

Award Winning Hup Range

The Hup 40-30 wins LLEAP Gold Award in 2017. This model maximizes profits with more job opportunities than ever before.

  • Maximum reach for class-leading performance : One mast provides two telescoping heights and four jib positions plus a potential partial jib. This versatility enables 20 possible crane configurations.
  • Multiple integrated configurations for various jobsite needs: Telescoping, integrated masts give you the option of working at heights of 21 m (70 ft) or 27 m (88.6 ft). In addition, automatic erection system requires no extra mast section to greatly reduce setup time.
  • Unmatched compact design for challenging jobsites and easy transport: the entire crane can be fitting in one high-cube container for shipment and can be transported on axles for land deliveries.

Innovative movement technology enables unfolding in
narrow and compact areas: Jib unfolds over the top to preserve
space under the crane when working next to buildings

  • The New Smart Set-up software simplifies crane erection using the exclusive Potain remote control and the electrical panel is easily accessible for convenient serviceability. The software has an  intuitive user interface for simplified, step-by-step crane erection  

In Conclusion, the self-erecting tower cranes is now replacing other forms of cranes for buildings below eight floors. All the above mentioned benefits ultimately results in more cost saving for higher efficiency on site.



New Potain Tower Crane Works As Topless, Stores As Luffer

Earlier in May, we spoke about hydraulic tower cranes and the MCH 125. Today, we will touch upon the MRH 125 which was launched at Bauma in April earlier this year.

The MRH 125 can lift up to 8.8 U.S. tons, be equipped with up to 164′ of jib, and lift 2.2 U.S. tons at the tip of the longest jib. Its maximum freestanding height is 190′, and maximum line speed is 387 fpm with 50LVF20 hoist winch. The Topless design with several elements making up the slewing crane part reduce the standard size and weight to make transport, handling, and fitting easier.

As with all of its products Manitowoc has placed a strong emphasis on return on investment for Potain MRH 125 owners. The crane’s adaptable design suits it for congested urban job sites while also optimizing transport and assembly times. “The MRH 125 has an optimized transport cost for a luffing jib crane in its capacity class,” said Thiebault Le Besnerais, Manitowoc‘s global product director for tower cranes. “It can also be mounted on our standard 1.6 m (5’6″) or 2 m (6’6″) K-masts for better optimization for fleet owners, and it offers lower power consumption than traditional luffing jib cranes.”

The MRH 125 also uses the latest luffing technology of the VVH hydraulic luffing mechanism which allows complete hoisting of the jib in two minutes. VVH hydraulic luffing eliminates the need to install luffing rope during crane setup. The hoisting winch, maintenance derrick, and jib wind side plate also come pre-installed to save setup time. Plus, there is no need to adapt the wind-sail plate on site, regardless of jib length. Also, the cab can be attached to either side of the mast to suit project conditions.

The jib can be raised from horizontal to near vertical (88°) in just two minutes, and the compact counter jib measures just 23’ and connects easily during assembly.

The main features of the MRH 125 are as follows:

It’s the perfect crane for confined areas

  • Almost vertical luffing jib for minimum space requirement when working
  • Weathervaning radius optimized for each jib length, just 10 m for the 50 m jib, ideal for congested jobsites
  • Option to fit the cab on the left-or right-hand side of the jib according to jobsite needs and especially to allow installation of the crane as close to the building as possible.

It’s the fastest fitting of a luffing jib crane

  • One single counter-jib/jib foot package bringing together all of the connected hydraulic functions. No inter-jobsite dismantling/fitting, compact and transportable in one package
  • No installation of luffing rope thanks to an innovative hydraulic system: save fitting time compared to traditional luffing system and increased safety

Transport is Optimized

  • Only 4 containers or 4 trucks for transportation of the whole slewing crane part with a 50 m jib

Optimized return on investment

  • Luffing jib crane adapted to very tight urban jobsites
  • Economical transport, easy and adapted to the fitting sequences
  • Fitting/dismantling time reduced through a design combining the Topless concept with hydraulic luffing technology
  • Improved fitting safety

In conclusion,  the MRH 125 has all the advantages of traditional luffing jib cranes with the capacities of the topless cranes. This combination of the best of both worlds ensures outstanding operating performance and guarantees a positive return on investment. To view the datasheet or request a quote, visit:

First quarter improvement for Manitowoc

Manitowoc Crane, which also includes Grove mobile cranes and Potain tower cranes has posted first quarter revenues 8.3 percent higher at $418 million.
The increase was attributable to higher crane shipments in the Americas and European regions, coupled with pricing improvements, partly offset by unfavourable changes in exchange rates. The pre-tax loss increased from 6.1 million in the same quarter last year to $23.4 million this year, entirely due to a $25 million charge for early extinguishment of its debt, when it refinanced on more favourable terms in March. Without this the company would have been back in the black with a profit of $1.6 million. At the operating profit level it made $16.2 million compared to just $1.7 million last year. Full year revenues are now forecast to be three to seven percent higher at $1.9 to $1.97 billion.

Chief executive Barry Pennypacker said: “Manitowoc once again delivered a strong start to the year, delivering our eighth straight quarter of year over year adjusted EBITDA margin increase. The operating principles of The Manitowoc Way continue to produce improving financial results as we execute our strategy for profitable growth by delivering innovation and velocity in everything we do.”

“In March, we successfully refinanced our capital structure to further strengthen our balance sheet. This action increases liquidity, reduces interest expense and allows us more flexibility to deploy our capital in order to increase shareholder value.”

“Market conditions remain very competitive. We continue to focus on providing innovative products and services for customers as evidenced by positive customer reception to our six new cranes introduced at the bauma trade show in April. As a result of our first-quarter performance and our proven ability to execute on our strategy, we are raising our full-year guidance.”
