Spotlight Cranes By Seth Skydel

The newest Potain self-erecting cranes from Manitowoc have the company’ s crane control system.

“ Contractors are finding the advantages to self-erecting cranes exceptional when compared to telehandlers or rough terrains,” Juhren said.“ With their long reach, full jobsite coverage without the need to maintain a roadway around the project is a big advantage. The small footprint of self-erecting cranes also makes them ideal for confined spaces, such as alleyways and courtyards, or when lane restrictions on the street confine the jobsite.”

Nicola Castenetto, sales leader, self-erecting cranes at Terex, said that self-erecting cranes are getting more popular in the construction business. That’ s thanks to their quick installation and as a single piece of lifting equipment the ability to cover all of the jobsite, reducing the need to have multiple machines moving around, he noted. Their noise-free operation also adds value.

However, the decision to buy new self-erecting cranes can still be impacted by other factors.“ Price increases for raw materials, construction materials, energy and rising interest rates can combine to make investment complicated,” said Christopher Noblit, director of engineering for tower cranes, North America, at Manitowoc.

The Latest Technologies

At the same time, Noblit is quick to point out that the newest models can be attractive because of technologies that provide advantages for crane users.“ On our new self-erecting cranes, we usually implement the crane control system( CCS), which adds functionality and simplifies the implementation of options like working range limiters,” he said.“ It also allows for setting cranes in a short time because the machine can be calibrated and safety devices adjusted using the CCS display in the cab.”

Manitowoc has also implemented Potain CONNECT telematic functionalities on its latest self-erecting crane models. The remote technology platform helps ensure uptime through access to data for troubleshooting and fleet management.

Kelly Webb, president at Creative Lifting, the U. S. distributor for Saez, pointed out the features and benefits of the manufacturer’ s all new HT47 cable erect self-erecting crane. The first Saez HT47 in the U. S. is now working in Colorado and more units are on order as well.

“ The HT47 crane is ideal for dealers, rental companies and end users looking to fill the need for a 154-foot jib length self-erecting crane,” Webb said.“ It also has four different jib lengths with the jib horizontal at 2 degrees or angled up at 30 degrees, which makes this model one of the most versatile on the market today. The HT47 is also easy to transport and erect and has the unique ability to run on single-phase power with no loss of speed or capacity.”

With the Saez direct service( SDS) system on the HT47, Webb noted, users can remotely connect to the crane and collect information on operating times, starts, brake use, work cycles, wind speed and other parameters to help improve the efficiency, reliability and safety of the crane and optimize its maintenance.

Other features of the Saez HT-47 include a zoning system, a Super- Lift mode, a compact 15-foot outrigger spread and five 8-foot mast sections to reach a 125-foot hook height. The crane also comes with the option of either a 9- or 11.5-foot counterweight radius.

New from the North American division of the Arcomet UPERIO Group is the Arcomet A50 ECO self-erecting crane. Joining the A40, A45 and A47 ECO CITY models in the company’ s self-erecting crane lineup, the A50 has lifting capacities of 8,820 pounds( 2-part) and 17,640 pounds.( 4-part) and a 3,310-pound capacity at its maximum jib length of 164 feet.

Andrew Stalter, Liebherr USA’ s senior sales manager tower & MK cranes, noted that advanced and smart crane control systems and drives assist with safety and efficiency.“ Our self-erecting cranes are secured with sensors that prevent overload,” he said.“ Other features, such as ABB( working range limitation), prevent swinging loads in hazardous areas, such as over train tracks or busy roads.
