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.
