| I was a guest to Cormach in Montichiari to take pictures of the new topmodel, the 575000A X - E9 J804. |
 |
| First the chassis, it's a rather special Volvo FH460 in 12x4*6 configuration. The truck will be shipped to Israel where it will be workinf for the company Otman. |
 |
| The base of the truck is a Volvo FH 8x4 on leafsprings. This was converted in the Netherlands by Terberg Techniek. They installed 2 extra axles at the rear The first one is a a heavy unit, it has the axle housing of a normal driven unit, but it doesn't have the drive parts. This axle has hydraulic suspension and hydraulic steering (the whole axle is moved by 2 cylinders). Behind this 16 ton (technical weight) axle they installed a 10 ton tag-axle with a 4 point air-suspension that has a electric-hydraulic steering system. |
 |
| Installed on that chassis was this impressive Cormach 575000. The extra axles are needed to cary the total weight of 63 tons, so I guess the axle loads are 9-9-12-12-12-9 tons. |
 |
| They have chosen the short cab, as the crane will fold down behind the cab. A sleeper cab would have made the truck longer. |
 |
| The crane sits at the rear of the chassis, so it is logical that most axles are positioned there to carry this weight when the crane is on the road. |
 |
| A big crane needs a lot of oil, so they installed this huge tank on the right side of the chassis. It has over 1000 liters of capacity! To the left of it we see some coolers for this oil. |
 |
| The front outriggers are swivveling and extend once. They have a fully extended support width of 12,33 meters. |
 |
| The wheelbase looks long, but as both rear axles are steering, the truck can still make good turns. |
 |
| At the rear of the truck we see a control panel for some hydraulics. Here you switch between controlling the outriggers or controlling the crane. By the way, the crane isn't finished on these pictures, so some parts still aren't mounted for easy access during testing. |
 |
| As you may have noticed, this crane has gotten a ballast system. The huge size and outreach of the crane just couldn't be handled without ballast. The ballast beams are boom sections from a 50 t/m Cormach crane, they can be extended for about 1,5 meters. Here only a part of the ballast is installed, the maximum ballast is 25 tons. |
 |
| Although electronic stabilizer control is already installed on the Cormach cranes, for this crane they developed a new electronic stabilizer control system. This allows you to set up the stabilizers in any configuration and the system will automatically adjust the lifting capacity. Here the right outriggers are full out, where the left one is only extended twice. |
 |
| Here we see why this crane has got the red "X" in his name. The X stands for the crossed outriggers at the crane base. These outriggers extend sideways and to the rear, giving nearly 100% capacity to the rear. This crossed setup lets them extend to the rear for a maximum of about 2,5 meters, they have a maximum support width of 11,4 meters. The ballast base-plate can lie on the top of these outriggers during transport, you can see the pads on the top left. |
 |
| With the crane operative, the suspension of the 5th axle retracts and therefore the axle lifts. |
