The next generation of CT cranes, the CT.4, is on the drawing board of Compact Truck AG in Switzerland. First orders for the new model have already been confirmed, but it will not be unveiled until early next year.
The new range is available in 110t and 150t classes and on four to six axles, to meet whatever road regulations purchasers are subject to. Earlier models in the range are the 40t class CT.2 and the 70t/80t class CT.3, which is avaialble in three or four axle configurations.
Compact Truck claims that the CT.4-110 and CT.4-150 are “the only mobile cranes in this kind of lifting capacity to be available on four axles”.
Sales manager Alexander Lutz told Cranes Today: “This is extremely important in Central Europe for example, where a total weight of 48t is often the limit for receiving a permanent travel permit. In this configuration without or with very little counterweight, the CT.4 models can still be used in the 70t or 80t class.
“On the other hand the customer’s requirements might be the ability to carry as much counterweight as possible on the crane to avoid additional vehicles. As a six-axle crane, the CT.4-110, for example, can carry 25t of counterweight while not exceeding the axle load limit of 12t. Another requirement might be axle loads of only 10t which can easily be matched by both CT.4 types.” The six-axle CT.4-110-C is 12.8m long in road-going configuration, and the four-axle CT.4-110-A is 11.75m long. This compares, for example, to 14.935m for the 120t class Liebherr LTM 1120/1, including boom overhang of 2.265m.
Width of the CT.4-110 is 2.75m and height is 3.65m. The boom extends from 8.75m to 59m, and can extend or retract under partial load. The six-axle CT.4-150-C is 13.5m long, and the four-axle CT.4-150-A is 12.9m. On each, the boom extends from 10m to 63m.
The manufacturer claims that additional equipment like a working platform or fork arms “can be mounted by the crane driver in a couple of minutes”.
