Borgers rocking hard with precision lift

Borger Cranes and Precision Rigging & Logistics recently completed a lift which stopped the Gold Coast as the lights were finally switched off at the iconic Hard Rock Café on Cavill Avenue, Surfers Paradise.

Borger Cranes was engaged by Precision Rigging and Logistics to assist with the crane hire and planning for the removal of the iconic Les Paul guitar from its rooftop position at the Hard Rock Café, where it had sat proudly since 1996,attracting many thousands of fans to the restaurant. 

According to Borger Cranes Supervisor Logan Alexander, the lift wasn’t without its challenges. 

“Because of the many risks involved, we were using smaller cranes in our fleet with our Liebherr LTM1060-3.1 and Franna MAC25-4, but the lift still took plenty of planning. Risks included the proximity of major retailers, which meant there were plenty of hoops to jump through. 

“On Cavill Avenue, there is a major supermarket just metres from the position of the cranes and the tram lines were a mere few metres in the opposite direction. This lift really took some planning – something that Luke Williams, Managing Director of Precision Rigging and Logistics and myself are used to, and as a result of the detailed planning, we once again nailed it,” said Logan.

With two blocks of Surfers Paradise shut down, the tram lines isolated, and the cranes positioned perfectly, the lift was completed without any issues.

“Our engineer estimated the weight of the guitar would be around 5t but it came in at 3.6t. This enabled us to configure the LTM 1060-3.1 with main boom and 12.8t of counterweight. We picked the guitar at a radius of 9m and landed it at 16m,” said Logan.

“There was no need for the SuperLift, so we configured the Franna with standard counterweight. The Franna was hooked on the lower end of the guitar to tail the load from vertical to horizontal, it then assisted the LTM 1060-3.1 with loading the guitar onto transport, as dual lift. From setup to pack up the job took five hours.

“From the start, there were a number of unknowns relating to the lift. We couldn’t get drawings for the guitar, so inspections were organised and we utilised John from Field Engineers for this process.

“Precision Rigging and Logistics removed the inspection hatches so a detailed report could be completed –  outlining the makeup of the guitar and its structural integrity. Precision Rigging and Logistics and Borger Cranes offered a turnkey package, from start to finish, leaving nothing in our way, and never letting any obstructions hinder the project,” said Logan.

Liebherr LTM 1060-3.1

The Franna was hooked on the lower end of the guitar to tail the load from vertical to horizontal, it then assisted the LTM 1060-3.1 with loading the guitar onto transport, as dual lift.

The 60t capacity Liebherr LTM 1060-3.1 has a 48 m telescopic boom and offers enormous load capacities. At a total weight of 36t and with a 12t axle load, it includes a 5.5t ballast, 445/95 R 25 (16.00 R 25) tyres, eddy current brake, 6 x 6 drive and a hook block. A special ballast plate configuration has been implemented in the design to  offer the widest range of driving conditions under its 12t axle load. Depending on the crane equipment and the required vehicle payload, the ballast carried may be 3.7t, 4.3t, 4.9t or 5.5t.

To increase the load capacity, 7.3t of additional ballast is available so that the 60t machine can be used with a maximum ballast of 12.8t. Thanks to its compact dimensions, the three-axle machine can be manoeuvred easily, even if on-site space is tight. The 9.44m long chassis is just 2.55m wide, even with the 16.00 tyres.. The turning radius measured over the driver’s cab is just 7.58m and the ballast radius is within 3.54m. A support width of 6.3m is achieved with single telescoping sliding beams. Where space is tight, however, a reduced support width of 4.5m or 2.3m can also be used. The crane can be completely levelled during the support process at the touch of a button.

The air activated disk brake first developed by Liebherr for a mobile crane gives the 60t crane increased safety and efficiency. They offer considerably greater braking force than conventional drum brakes, which remains consistent even at high brake temperatures. Changing the brake linings is faster and easier, and they come equipped with wear indictors to signal when this should occur. The much longer service life durations also contribute to efficiency. 

The active, speed-dependent rear axle steering system from Liebherr, tried and tested many times over, is used in the LTM 1060-3.1. This reduces tyre wear considerably. The driver has five different steering programs available that can be selected easily for a variety of driving situations.

The six-cylinder Liebherr in-line engine in the chassis achieves 367 horsepower (270 kW) and reaches a maximum torque of 1700 Nm. The force is transferred to the crane axles via the 12-speed ZF-AS-transmission. A two-stage distributor gear permits minimal creeper speeds in manoeuvring mode. The ABS (anti-lock braking system) improves driving safety significantly.

The LTM 1060-3.1’s six part telescopic boom uses Libherr’s Telematik telescoping system to telescope in and out easily. Using a 9.5m-16.5m swing away jib, the unit can reach hoisting heights of 63m and boom radii up to 48m. The swing away job can be attached at an inclination of 0°, 20° or 40°. For work in two hook operation, a second hoist gear and a 2.5 m assembly jib and a rooster sheave is available.

The LTM 1060-3.1’s hydraulic lift system uses an electric “Load-Sensing” control that can actuate up to four movements simultaneously. Depending on the requirements for the lifting task and of the crane driver, the slewing gear can be easily switched from “open” to “hydraulic locked”.

It also uses the Liebherr LICCON2 crane control – a mobile, multifunctional control and display unit with a BTT Bluetooth terminal. The crane driver also has the option of attaching and removing the hook block on the crane bumper with visual contact via remote control of the hoist winch and the luffing cylinder of the telescopic boom.

The Liebherr LICCON2 mobile crane control can also be converted into a complete remote control system for the crane.

Precision Rigging and Logistics removed the inspection hatches so a detailed report could be completed, outlining the makeup of the guitar and its structural integrity.

Franna Mac 25-4

The MAC 25-4 is a mobile articulated crane with a maximum lifting capacity of 25t. It offers a design proven in a range of difficult lifting applications.

While it wasn’t necessary this time, the MAC 25-4’s optional superlift (SL) upgrade works in tandem with the existing MAC 25 counterweight, adding a low-slung additional counterweight piece to the rear of the machine that helps increase rated capacity of the machine by up to 30 per cent in some configurations.

First released in 2013, Franna’s patented Dynamic Load Moment Indication (LMI) system offers real-time calculation of rated capacity, taking into account boom configuration, as well as chassis articulation and pitch and roll, enabling continual assessment of structural limitations, forward stability and side stability.

Increased resolution of rated capacity is made possible by finer measurement of articulation pitch and roll angles – which allows for improved machine capability compared to previous generation LMI systems. When operated over undulating terrain, the rated capacity will be updated continuously, providing instantaneous information on the percentage utilisation of the machine (0-100 per cent of available capacity). When operating on a side slope or undulating terrain, operators are no longer required to manually calculate a reduction of rated capacity; the Franna Dynamic LMI does that.

Reflecting on a job well done, Logan says the cranes were ideal for the lift .

“The Liebherr LTM1060-3.1 and Franna MAC25-4SL were the perfect cranes for the lift. They made the job quick and easy, and damn they look good doing it!” 

“A massive thanks to the Borger Cranes’ crew for being able to adapt to the changing conditions quickly on their feet, going above and beyond as they normally do and for showing why we are the benchmark for mobile crane hire in South East Queensland. 

“A special thank you to Luke and his team at Precision Rigging and Logistics for their ‘out of the box’ lifting solutions. Do not settle for less on your project, we have teams and partners dedicated to making your job easier, give us a call to streamline the process,” said Logan.
