20T Franna Crane Truck For Hire: Summary of Specifications and Capabilities

The 20T Franna crane truck represents the cornerstone of any crane hire operation. It’s built to deliver a profile that sits comfortably at that critical size range, the pivotal point that balances easily between size and lifting capacity. The workhorse vehicle boasts a boom length that begins at 5.67 Metres, but this rigid lifting arm can extend in 4 powered stages to reach 17.9 Metres, a range that’s counter-balanced by a long and compact carrier, a chassis that’s as stable as it is robust.

Further details on this powerful all-rounder include the dimensions of the vehicle. At 9.67 Metres long by 2.5 Metres wide, the structural integrity of the 20T Franna crane truck is assured, especially in the competitive “pick and carry sector,” a load and lift domain that requires a profile that can manoeuvre quickly and lift efficiently. The Mercedes 6 litre intercooled turbo power plant assures us that customers will be happy with the former activity, while the latter function, that of lifting prowess, is addressed by the power boom and its 20T lift capacity. Please note, lift aptitude is affected by boom length and angle, factors that can be resolved into real world values by checking the load charts included in the vehicle manual.

These are a lot of figures, facts and bland statistics that will inform the operator and confuse the amateur, but they are key in describing the 20T Franna crane truck as the master of its lifting category, and that category covers the majority of light to medium load scenarios. A second wave of incorporated features reinforces lift capabilities. These focus on safety and functionality. For example, a wealth of load-specific information is delivered in clear-cut, no-nonsense language within the manual. The data illustrates angular charts, documented evidence of the effects of alternate boom extensions and how the fly jib adds or detracts from the operator’s handling experience. Next, the maximum 85 km/h road velocity limit contrasts with the all-terrain semi-elliptical suspension and the front-axle torsion bar, a feature that injects enhanced stability into the mix.

Servicing the industry with plucky disdain for the competition, this mobile crane truck has few rivals when it comes to general fleet hire. The 2-speed winch line and its associated sling and hook block derive 4.2 tonnes of pull from the powered drum. Meanwhile, all of this smooth-moving force is rooted in the hydraulic pump, a load sensing axial unit that can deliver 126 litres of fluid per minute and do so at a working pressure of 250 Bar. And, in covering all of this all-inclusive excellence we haven’t even touched on operator extras or the ability to slew articulation by 40° to either side of centre. In favour of operators out there, we will quickly add the fact that the spacious cabin features full power steering and a number of braking enhancements, plus stylish binnacle-type instrumentation gauges.

Capabilities of Demag AC120 Crane Truck

The Demag AC120 crane truck offers outstanding all-terrain performance. An optimized 120 tonne lift aptitude provides a benchmark in heavy load hoisting, but such beefy cargo conveyance requires something a little special in the chassis department. The 12 Metre carrier length partners with a 3 Metre chassis width and a further 7.5 Metre additional width in the form of powered outriggers. These stability supports telescope horizontally to anchor the vehicle in place, no matter how tilted or soft the soil on the work site may be. Once anchored, the 12.9 Metre seated boom can rapidly telescope to an impressive 60 Metres.

As one of the mainstays in the industrial and commercial sector, the Demag AC120 crane truck uses its 5 axles to trundle efficiently from one construction site to the next. The elongated boom and the compact profile situate this model at the midpoint of a large range of muscled lifters, meaning this model is at home on a large construction site as it is below a newly constructed apartment complex. We could imagine the boom lengthening in intermediate stages to its full span to convey massive air conditioning units to the top of a multi-storied apartment block, pausing only to finitely adjust the boom extension and the rigging. Additionally, the driver can quickly navigate the many obstacles and narrow avenues on a building site, using the 5-axle configuration to pull the rear end closer to the loading zone. The fully configurable independent steering mechanism attached to the fifth axle maximizes this flexible turning aptitude, adding to the already tight 11.9 Metre turning radius of the mobile crane. In short, in a world where wind turbines climb to the sky and massive environmental control units sit on top of tall structures, this easily rigged crane truck is an ideal match.

It takes a steady hand and a pinch of physics to enable this kind of heavy lifting power. A 28 tonne counterweight works in concert with the five stage boom. The boom itself is manufactured from fine grain structural steel, and all of these disparate elements are controlled by the nerve centre, a spacious control cabin that contains a bay of instrumentation and advanced monitoring stations. And, if this cabin is the metaphorical brains, then the Daimler Chrysler 6-cylinder engine is the heart. If these compelling specifications aren’t enough to raise the Demag AC120 crane truck to the peak of the international crane truck pile, independent hydraulic dynamism is on hand in the shape of a powerful displacement axial piston pump, a component that easily manages 4 simultaneous working actions.

This 5-axle beast from Demag is a flagship lifter, but there’s more to recommend before we conclude this examination. We’ll finish with two optional extras, the addition of supplemental counterweights and tyre modifications, options that extend the prestige of an already popular industrial-class vehicle.
