ALL TERRAINS Ӏ SECTOR REPORT
j Even with the six-stage boom installed, the AR-7000N has a shorter overall length than the AR-5500M at 18.82m. It has an outrigger installation width of 9.0m and a tail swing of 6.3m, all with a higher lifting capacity. This crane, too, comes with a newly-designed cab.
Asia is clearly an important
market for all-terrains. Manitowoc have recently appointed a distributor for their Grove all- terrains in Japan, their first in that region, where the company is strengthening its operations. And, as with Tadano, it is producing variants specially designed for the Japanese market. G Machinery, the new
distributor, is based in Tokyo; shortly after coming on board it sold and delivered its first two cranes; one is a GMK5150L-1J, the other a GMK5250XL-1J. The “J” denomination reflects that their design is tailored specifically for Japan. Both were sold to a leading Japanese crane rental company. Shohei Konno, president of

G Machinery, said the reputation and product quality of Grove cranes will make them an attractive option for customers in Japan. G Machinery will offer the full range of Grove all-terrain cranes. It expects the six-axle and five- axle models to be particularly popular due to their load charts and manoeuvrability. The five-axle GMK5150L-1J is the most powerful crane in its category, with a capacity of 11.8t at the end of 60 metres of main boom which can be lifted out to a radius of up to 18 metres. The GMK5250XL-1J has a 78.5 metre boom – the longest in the five-axle class – with 250t capacity. Both cranes feature Grove’s Megatrak suspension and Manitowoc’s Twin- Lock boom pinning system. New cabs for all-terrains seem
to be universal just now. It is not entirely a coincidence: changing European crash-test regulations have been necessitating some changes, and manufacturers seem to have taken the opportunity to go for re-designs rather than make-overs. We have
described Liebherr’s and Tadano’s contributions so we should mention Grove’s latest efforts as well. They based it on surveys of their customers and operators – and, more unusually and imaginatively, of their employees who actually build the cabs as well. They point out that crane operators not only drive from their cabs but also spend all day working from them as well, so ergonomics and small comforts become important. The prototype was shown at Bauma 2019, where visitors were asked to sit in it and their feedback was incorporated as well. One example of the company listening to these last suggestions was the addition of armrests to the driver’s seat to make long-distance driving more comfortable. The new carrier cab passed every stress test and also its crash-test at the first time of asking. This means it is now fully ECE R29-3 approved. The first units on three-axle carriers have recently been delivered; the versions for the five-axle and four- axle models will follow.
