Exploring new markets, Borger Cranes adds a 750t Liebherr to its fleet, reflecting the demand from industry sectors for higher capacity cranes. Cranes and Lifing explains.

Borger Cranes and Rigging Services recently added a Liebherr LTM 1750 9.1 to its fleet. It’s a significant addition and one that will open new markets, says general manager Shawn Borger.

“The purchase of the Liebherr LTM 1750 9.1 is a direct result of the progression we are making within Borger Cranes. We are constantly evolving our fleet to enable us to provide the right cranes for customers and also to open new markets for our business.

“This crane has been in the planning for some time and with the assistance of the entire team at Liebherr, it’s arrival has come at just right time. A constant updating of our fleet ensures we are keeping up with the latest technology enabling us to provide our clients with safer and quality lifting solutions. The team at Borgers are very excited to take delivery of our 750t crane and it’s arrival coincides with our company celebrating 40 years in business,” Borger said.

The 9-axle machine features the very latest mobile crane technology and includes Liebherr innovations such as VarioBase and ECOmode. With its Y telescopic boom guying and a very wide range of lattice jibs, the LTM 1750-9.1 has a large number of boom systems. These enable it to achieve hoist heights of up to 154m and radii of up to 112m. The luffing lattice jib can be assembled in 3.5m stages up to a total of 91m.

The LTM 1750-9.1 has the capability to become an 800t crane. It has higher lifting capacities across almost the entire working range, and it has greater capacity for wind farm application due to new luffing jib configuration

The Liebherr LTM 1750-9.1 is far stronger than its predecessor and the use of refined static calculation methods means that lifting capacity values have been increased across almost the entire working range.

Liebherr has compiled a new luffing jib configuration using existing lattice sections to provide additional capacity increases for wind farm applications

The wide-ranging experience that the design engineers and structural engineers have with thin-walled boom profiles has enabled the popular calculation models and approaches of the Finite Element method to be further refined.

Supported by high- performance computers, the real load-bearing structure of the crane is simulated even better in the static calculation model. Liebherr has now transferred the latest findings and methods, which had already been applied in the LTM 1650-8.1 to the LTM 1750-9.1. The most recent calculation standards have also been taken into consideration.

The result is that the lifting capacities of the 750t are now higher than originally calculated across the vast majority of working ranges.

The new load capacity tables also contain a table with the nominal max. load capacity of 800 tonnes. Operators of the LTM 1750-9.1 now have the possibility to update the crane software with the new tables and, if necessary, to add any additional equipment required.
Thanks to the new luffing fly jib configuration, the LTM 1750-9.1 has moved into a higher load capacity class in the area of wind farm applications. More than 10 tonnes of additional load capacity can be generated for the mounting of wind turbines on 90 and 100-metre-high towers. The LTM 1750-9.1 is also much stronger in the area of heavy load lifting, such as the loading of transformers onto ships, with typical working radii of 12-16 metres. The gain in load capacity in such applications is in excess of seven tonnes.

Liebherr now additionally offers load capacity tables for three wind velocities for this crane and for the latest new developments, giving the customer significant support in both job planning and operation.

Borger believes with this increase in capacity provided by LTM 1750, Borgers are well positioned to engage with wind farm contractors and also the mining industry as well as the traditional infrastructure and construction sectors.

“With this increase in capacity we are well positioned to service the renewable energy industry, especially the wind farm sector which is only going to grow in the future. We are seeing mining equipment constantly increasing in size and capacity and the 750t will enable us to work on major mine shutdowns and maintenance projects,” he said.

“The construction sector, and particularly with infrastructure projects, we are seeing everything being manufactured built on a much larger scale. This means we are lifting heavier components further and for this type of lift to be completed safely, we need capacity in our fleet. The 750t provides Borger this capacity. We’re also planning to have the 800-tonne upgrade package installed mid-year which will provide even more capacity,” said Borger.
Borger Cranes has also worked closely with TRT on the LTM 1750 project, says Borger.

“Borger Cranes has been buying specialist trailers and large outrigger pads from TRT for a number of years and they designed and manufactured pads especially for the 750,” Borger said.
TRT’s crane outrigger pads are specifically designed for the crane industry. They have been developed for maximum strength with Hardox high-tensile steel using a honeycomb construction to minimise tare weight and overall footprint. The unique design of these crane pads helps to minimise deflection and helps protect underground services from damage.

Because they are being used as outriggers, they are constructed using TRT’s diagonal bracing design and honeycomb internal structure. They are engineered to support a centred capacity of a 250t load.

These steel crane outrigger pads are ideal for use with a full range of cranes and site conditions and available in both standard sizes and custom options. The pads ensure a crane is supported safely for all ground conditions making site and lift planning simple. The non-slip surface and angled sides are designed to make the pads safer on site. The outrigger pads angle sides prevent tyre damage to other vehicles, especially in smaller work areas.

TRT’s quality outrigger pads are easily deployed on any job site, are being used on construction, and lift sites throughout Australia. Transporting, lifting and moving is no problem, each pad is fitted with rated lifting lugs, with options for forklift pockets.

“We’re very happy with the support and service provided by both Liebherr and TRT, they continue to go above and beyond in helping Borger Cranes provide the best possible outcomes for our customers,” said Borger.
