At what proved to be a very successful Vertikal Days event for the company, Liebherr is pleased to report that long-standing customer, Bronzeshield Lifting, placed an order on their stand for its third heavy-lift mobile crane this year. Scheduled for delivery in October, a 350 tonnes capacity LTM 1350-6.1 will join the Bronzeshield fleet as part of their continuing policy of owning and operating the most modern and high-technology fleet of cranes. This latest order follows deliveries earlier this year of an LTM 1500-8.1 500 tonner and a 200 tonnes capacity LTM 1200-5.1.
The LTM 1350-6.1 made its UK show debut at Vertikal Days. Equipped with a 70m telescopic boom and, with the Y-suspension boom system for enhanced lifting capabilities, this model is believed to be the strongest six-axle crane on the market. Adding the 78m luffing fly produces a maximum under-hook height of 132 m. A significant benefit to users is that the LTM 1350 can be road travelled with the Y-suspension boom system in place, while still complying with STGO regulations for axle weights.
The LTM 1350-6.1 carrier is driven by a powerful 8-cylinder Liebherr diesel engine rated at 450 kW. The automatic transmission is a 12-speed ZF TC-Tronic gearbox and a torque converter is installed drive-off and sensitive manoeuvring. The four rear axles of the crane's six-axle chassis are actively steered by an electro-hydraulic system, dependent on road speed, which greatly improves manoeuvrability and reduces tyre wear. During crab steering, all six axles are steered and five steering programs can be selected at the push of a button.
The Liebherr 4-cylinder engine on the crane superstructure develops 180 kW; crane drive is diesel-hydraulic, with five variable axial-piston pumps, a servo control system and load sensing control. For maximum sensitivity the winches and the slewing gear are operated by closed circuits - four simultaneous working movements are possible.
The LTM 1350-6.1 features the Liebherr LICCON2 crane control system and the BTT-Bluetooth function, which pro-vides operators with wireless remote control for all super-structure operations, plus outrigger activation and position-ing, engine start and stop function and engine speed, elec-tronic inclination display and automatic leveling during set-up. Using the new BTT-Bluetooth system, the crane operator can also attach and detach the hookblock from the front bumper by remotely controlling the hoist winch and the luffing ram on the telescopic boom - all under close view. Activation of the telescopic boom luffing ram through the Bluetooth connection is also possible, as well as attaching the counterweight and for self-assembly of the Y-suspension system. Another user benefit is that, during road travel, the BTT-Bluetooth terminal can be plugged into the driving cockpit for the display of mileage and working hours information.
Commenting on his latest fleet acquisition, Bronzeshield's Bill Frost said "In spite of the on-going economic difficulties, we at Bronzeshield continue to invest, ensuring that we operate a thoroughly modern and reliable fleet of cranes for our customers throughout the UK. Although this new 350 tonne Liebherr is a replacement crane, it is not on a like-for-like basis but is another addition to the heavy-lift end of our range with excellent performance right through the duty charts".
