TRUCK CRANES Ӏ SECTOR REPORT
Spectacular sight: Sany truck cranes in uzbekistan
Chinese manufacturer Sany also make truck cranes, in 45 tonne, 90 tonne, and 100 tonne-plus versions. A repeat customer in Uzbekistan has just received another 23 units of the 45 tonne STC450 truck crane. Dependability, strength and technological sophistication, says the company, are the reasons for their popularity in that country.
experiences much less wear in comparison to an all-terrain crane. It is way more cost-effective than many other options,” he says, adding that the crane’s extraordinary versatility is also a plus factor worth considering. The latter is due in part to the
fact that Brielmann ordered the crane with all the bells and whistles – including a trailer that carries the counterweight. He also has a runner, an emergency lowering system for projects that need a man basket, a camera system, and a wireless remote control that is particularly useful when mounting counterweight elements from the trailer. A large truck is obviously less
manoeuvrable than a small one. A heavy crane needs a large truck to move it. A light crane needs only a small truck to move it. Böcker, the German pioneer of aluminium in crane-making, applied this logic back in 1989, and ever since then has been producing cranes on very small and light trucks

indeed, which makes them ideal for city-centre work, especially in the narrow city streets of much of Europe. Roofing work, carpentry, and facade construction and repair are among such applications. The concept took a while to establish itself in the UK, but that has now changed – see box on p46. And since those early days it has added radio control with colour graphic display and optional camera technology to its truck cranes. The AK 52 is its strongest
crane, and perhaps also the strongest of any aluminium crane. It lifts a load of up to 12 tonnes and has an extension length of 52m, with an option of 55m. Mounted on a 26-tonne truck it can lift 100kg to 30m radius and 34m high. It can also be used as a work platform. The AK 46/6000 fits on a
smaller truck, of 18 or 16 tonnes. It lifts a maximum of six tonnes and has an almost circular working area. The reach is 26m with a 1000kg load and can be fitted
with a double fully hydraulically extendable luffing jib as an option. The AK 37 fits on a 7.49 tonne chassis. (Böcker uses MAN or Mercedes). It designed it for roofers and carpenters who want to reach the rear roof and building sites; with a load of 250kg the AK 37 achieves a height of 28m. It also is extremely compact since it has no overhanging mast top. Because of the very small slewing radius of the crane superstructure, and the possible one-sided support from the hydraulic outriggers it can work from it even while road traffic is flowing. In the latest generation the crane is also available as an electric version, the AK 37e, which has additional e-drive and battery with 230 V charging technology. So, define them how you
will, truck cranes are useful and economical – to run and to buy. And if our old definition of a crane on the back of a truck is not quite accurate anymore, it still reasonably well describes the concept.
