Italian spider and mini picker crane manufacturer Jekko is launching a new second generation version of its 15.5 tonne JF545 articulated tracked crane, the JF545.2. Hopefully you will be able to see it at Vertikal Days in two weeks’ time, in the meantime here are the details.
The new Jekko JF545.2
The original JF545 was launched in 2017, the first unit to emerge after Fassi bought into the company in 2016. It has gone on to become one of the manufacturer’s most popular big crane models. The new version retains the same six section boom and seven section jib - including manual section - for a maximum tip height of 32.5 metres at which point it has a capacity of up to 450kg, the same capacity is possible at the crane’s maximum radius of 30 metres. 450kg is also possible with the boom fully elevated and the jib horizontal for a radius of 16.5 metres at an up & over height of 19 metres.

A key improvement on the new model is its Variable Speed Engine Management system which matches the engine speed to the function operated, and is said to provide faster, smoother and more precise operation along with reduced fuel consumption. The operator can also choose from three working modes – Eco, Normal or Power, each of which have a different performance characteristic, suited to different applications. Engine information such as RPM, fuel levels and the time remaining before needing to refuel are shown on the crane’s seven inch touch screen display panel which is waterproof to IP66 levels and features a new more intuitive interface and a wider set of functions.

The crane’s diesel engine is equipped with a new DPF filter with automatic management for lower emissions, while a three phase plug in electric motor is available for working indoors or in noise/emission sensitive areas. The hydraulic system has been redesigned and now incorporates a dedicated electric powered hydraulic oil cooler.
In terms of the crane’s structure, the three section outriggers now have a greater number of set up configurations. When stowed the crane has an overall width of 1.84 metres, an overall height of 1.83 metres and is 5.83 metres long.
The outrigger set up options
New options include a low temperature pack with a pre-heating kit for counties with extreme cold and a work platform that offers a maximum working height of 32.2 metres and a platform capacity of 200kg.
