Italian crane manufacturer Jekko is to launch a larger, higher capacity 'JF' knuckle boom spider crane, the 22 tonne JF1050.
The new crane fully stowed - note the two counterweights
The new crane becomes the largest model in the company’s range and includes some major upgrades and improvements over existing models, which one assumes will gradually be carried over to the smaller units.
Unfolding with 4.9m square outrigger footprint
It features a nine section decagonal cross section main boom with a maximum tip height of 23 metres, at which point it can lift 5,500kg, while the maximum radius is 20 metres with a capacity of 3,085 tonnes. An optional seven section jib takes the maximum tip height to 34.5 metres with a capacity of 950kg at a radius of almost 11 metres.
The jib can luff down to horizontal with the boom at 70 degrees and handle 850kg at a height of 22.5 metres and a radius of 18 metres. With the boom and jib fully extended and horizontal, or up to 10 degrees above horizontal, the capacity is 860kg at a radius of 32 metres. A range of work platforms are available, which offer a maximum working height of just over 36 metres.
The range diagram with jib
The crane has an overall stowed width of 2.2 metres, an overall length of 6.75 metres and an overall height of 3.47 metres. The counterweight is made up of two parts, one weighing two tonnes and the other three tonnes, with load charts for no counterweight, two tonnes, three tonnes or five tonnes. Total overall weight is 27.7 tonnes, which can be reduced by removing one or both of the self-install counterweights as well as the outrigger beams.
Some of the outrigger configurations
The winch has a maximum line pull of two tonnes with 60 metres of wire rope storage, allowing below ground reach of up to 51 metres. The outrigger spread is variable, from a simple square footprint of between 4.91 and 8.5 metres, or inboard to an overall length of 11.35 metres. Intermediate outrigger spread options and one side set-ups are also available with the actual configuration fed into the crane’s operating system and displayed on the seven inch fully waterproof touch screen.
The operator’s display screen
As with all of Jekko’s JF articulated models, the JF1050 uses a crane from Fassi, with which it has ownership connections. Power options include bi-energy - diesel with an integrated electric motor providing full autonomy outdoors and clean, quiet operation indoors, pure diesel or a full electric plug in system.
Optional track pads
A new Variable Speed Engine Management system provides smoother, more precise operation and lower fuel consumption and allows the operator to choose between three working modes – Eco, Normal and Power. All engine data and details are available on the crane’s main display screen.
