A 70 tonnes capacity LTM 1070-4.2 mobile crane has been delivered to Cadman Cranes Ltd and is the first Liebherr to join the company's growing and modern fleet which currently stands at 22 cranes.
Formed in 1959 as a general plant hirer and earthmoving contractor, Cadman first moved into cranes in 1976 and now offers a range of machines for a variety of applications. The fleet includes mini crawler cranes, truck-mounted and all-terrain models and a specialist midi crawler crane with telescoping boom and rotating grab for highly specialised rehandling work aimed at general materials handling as well as drainage authorities. Cadman Cranes is a family owned, independent organisation based in Colchester providing crane hire and contract lifting services to public utilities, local and national companies throughout Essex and East Anglia.
Cadman Cranes has taken the Liebherr LTM 1070-4.2 with high specifications. An extremely compact four-axle 8X6X8 all-terrain crane, equipped with a 50m telescopic boom, this model has been supplied with a 9.5m-17m double wrap-around fly-jib which can be offset to 0°, 20°, 40° and 60°. The fly-jib also has an integrated 3.2m assembly jib with a set of sheaves and which can also be offset to 0°, 20°, 40° and 60°. The assembly jib is extremely useful, especially where head height is restricted, with the offset variances giving the operator extra clearance from the boom when lifting larger items at height.
A 38.3 tonnes hookblock with 3 sheaves and a 16.90 tonnes hookblock with 1 sheave have also been supplied and the 10.70 tonnes basic counter weight is augmented by an additional 3.80 tonnes of ballast. Main boom maximum under-hook-height is 50 metres and the lifting capacity is an optimum 0.8 tonnes at 44 metres radius. With maximum fly, the under-hook-height attains 65 metres with a 0.7 tonnes capacity at 48 metres working radius.
The LTM 1070-4.2 is powered by a 6-cylinder Liebherr diesel engine rated at 270 kW. The automatic transmission has a 12-speed ZF AS-Tronic gearbox and the two rear axles feature hydro-mechanical speed regulated steering, which greatly enhances manoeuvrability and reduces tyre wear. Crane drive is diesel-hydraulic with a servo control system and electric load sensing control; four simultaneous working movements are possible. The air-conditioned crane operator's cab can be tilted backwards for optimum working visibility during lifts and is a typically comfortable and functional work-station with full instrumentation and the highly developed advanced technology LICCON2 crane control system and BTT-Bluetooth terminal.
Cadman Cranes' LTM 1070-4.2 also has some additional operational safety features, which include twin working floodlights, aircraft warning light, working area limitation and the LICCON Lift Planner system. A Liebherr designed integral tackle box and a box for support timbers have also been supplied and installed on the crane carrier for safety and convenience. As with all new generation Liebherr cranes, this model is equipped with the latest GSM module technology which provides a direct on-board link between the customer and Liebherr's after-sales engineers, both in the UK and the European factory, to assist assist in diagnostics and fault-finding should the need arise.
Cadman Cranes, Managing Director, Geoff Cadman, commented "We're delighted to have added a Liebherr crane to our fleet and are confident that it will give us long, reliable and productive service".
