Ranger Lifting - Rigging and safety gear for Australia

The lifting and rigging equipment company named after football team Queen’s Park Rangers! Ranger became Australia’s first full member of the Lifting Equipment Engineers Association (LEEA) in 2011. New South Wales-based Ranger recently opened a new facility in Melbourne, Victoria having moved to expanded headquarters in Prestons, Sydney. Ranger’s portfolio is comprehensive, including a full range of slings, shackles, other below-the-hook equipment, and height safety solutions. Manufacturing is typically associated with wire rope and chain slings, but they also make lifting beams and jib cranes in line with demand.

Ranger Customises Vacuum Lifter for Tunnels Project

Ranger Lifting has modified a vacuum below-the-hook attachment for installation of key elements, as a large railway project enters a key phase.

Prestons, Sydney-based Ranger, a specialist supplier of lifting and rigging equipment, has adapted the Acimex vacuum lifter, manufactured in France, to meet specific requirements for installing 1,000 elements over a two-year period, as a tunnel boring machine (TBM) is prepared for work. Leo Giuntini, business development manager at Ranger, explained that the elements are thicker than the standard units used elsewhere because of the soil environment along the boring route.

The attachment will work with a 3t capacity, 44m-long, freestanding monorail hoist that originally had a working load limit (WLL) of 900kg, increased by Ranger to 1,350kg. Additionally, Ranger has changed the orientation of the vacuum head 90 degrees and lengthened the support bar. Acimex manufactures all types of vacuum lifters for gripping bulky concrete, steel, or PVC parts, but the adaptation of this model once again demonstrated Ranger’s ability to tailor a solution for a specific project.

Giuntini said: “The project had a requirement to install key elements to facilitate use of a big TBM. The modernised attachment will be used to lift the elements out of moulds that are specially manufactured upside-down, so they have to be rotated in the air prior to installation. Importantly, the vacuum tool must be able to hold the segments even when disconnected from power.”

The solution represented a significant time and cost saving for the customer, as the alternative to customising the existing product would have been to source a new one from France. Upon consultation with the end user and a local engineering firm, Giuntini was able to oversee the modernisation project that delivered a suitable solution to the client. As required under Australian Standard AS 4991-2004, the new product, operated by hand grips, had to receive third-party verification and was proof loaded to 110% of the WLL. A larger vacuum pump was also fitted for the extra capacity.

Ranger is frequently engaged in tunnels projects, above and below the ground. Whether it be the installation of jib cranes at the surface for emergency rescue or the provision of ratchet lever hoists and rigging for use many metres below, it is always important that equipment stands up to the rigours of the sector and meets the demands of one of the toughest environments there is.

Giuntini said: “The [tunnels] industry serves as an example as to why it’s always important to source lifting and rigging gear only from specialist providers. It is one of the most challenging but rewarding sectors to serve.”
