Luffing crane in Derry from Mantis Cranes

Old and the New side by side in Derry

The first Luffing Jib Tower Crane was installed in Derry last month, alongside the only double-decker bridge in Ireland.

A Saez SLH 205R Luffer was installed close to the Craigavon Bridge, one of the few double-decker road bridges in Europe. Construction started on the bridge in the late 1920s and was completed in 1933. The lower deck, which originally carried a railway line, was replaced by a road in 1968.

Luffers, with their unique jib which can be raised and lowered in a motion known as luffing, are distinct from Tower Cranes with their traditional fixed horizontal jib. The luffer can work in restricted spaces, near tall buildings, or on sites with multiple cranes due to its reduced swing radius.
The SLH205R is perfect for the construction site in Derry, where new apartments are being built overlooking the Craigavon Bridge, as the site is adjacent to existing apartments and retail businesses.

Key Features of Luffing Jib Tower Cranes

  • By raising and lowering the jib, the crane can be used to its full potential while avoiding any over sail issues.
  • When out of service, the luffer can be parked at a reduced radius compared to a tower crane, which must be left parallel to the site with the jib at a fixed radius.
  • On projects where there are multiple cranes, the reduced slewing radius of the luffer, compared to a tower crane, makes it the perfect option.
  • A luffing jib tower crane will not encroach on other crane’s working areas and will ensure an efficient and safe lifting solution.

The safe and efficient operation of a Luffing Jib Tower Crane requires skilled crane drivers due to the complexity of the luffing mechanism of the crane.
The increasing use of luffer cranes in modern construction can be attributed to their flexibility, leading-edge technology and improved safety and efficiency when working in urban settings.

    In 1999 when Mantis Cranes introduced the first self erecting crane to the Irish market, the Ma-sol 18 06 had a maximum lifting capacity of 1,500 kg. Fast forward to 2024 and the self erectors in the Mantis Cranes range now lift loads up to 6 T, with tower cranes lifting up to 24 T. Advancements in crane capabilities in response to changing customer requirements have resulted in a very different landscape for the crane hire industry.

    When restoring historic buildings, care must be taken to preserve these buildings for future generations. Cranes play a crucial role in this process and provide the necessary means of material handling, access, precision, and safety required to carry out restorations without causing additional damage. Over the years, Mantis Cranes have been involved in a number of iconic projects in some recognisable places that involved considerable planning not just to put the crane in place but also for the daily management of materials handling.
