Advanced Siwertell road-mobile ship unloaders specified for strategic cement handling project 

11 Jun 2025

Bruks Siwertell has secured an order from Italian construction materials specialist, Calme SpA, for the delivery of a new next-generation Siwertell 10 000 S road-mobile ship unloader and the refurbishment of a pre-owned Siwertell 10 000 S unloader, originally delivered in 2014, which will be upgraded to the same advanced, next-generation standard.

“Calme opted for our Siwertell road-mobile ship unloaders as we have a great track-record in similar cement handling applications,” says Jörgen Ojeda, Sales Director Mobile Unloaders, Bruks Siwertell. “We could also deliver on a tight schedule and offer robust technical support.

“Sustainability is a top priority for Calme,” continues Ojeda. “This order reflects the company’s ongoing aim to invest in advanced technologies and environment-friendly solutions.”

At their undisclosed location, the units will face challenging operating conditions, including high humidities and an abrasive, dusty atmosphere. “Siwertell road-mobile ship unloaders are specifically engineered to handle such demands and do so with reliability, agility, outstanding through-ship performance, and market-leading efficiency and environmental protection; the pair are an ideal fit,” emphasizes Ojeda.

The decision to upgrade the pre-owned road-mobile unloader to next-generation technology means that both units will benefit from advanced digital solutions and an integrated communications system that enables remote access, troubleshooting and support. This can be further upgraded in the future if the owners want to take advantage of Bruks Siwertell’s latest service support packages, which include the use of an augmented reality (AR)-kit.

“This is a very exciting project for us, and the delivery scope demonstrates our ability to think dynamically and offer customized solutions to meet specific needs,” he adds. 

Both trailer-based, diesel-powered units will offer a rated cement handling capacity of 300t/h, discharging vessels of up to 10,000 dwt, and have a double-bellows system for efficient material discharges. They are fully enclosed, eliminating spillage and minimizing fugitive dust, and are scheduled for delivery by mid-October 2025.
