The new generation of Krone Box Liners is based on a multifunctional modular system that enables the transport of all types of sea containers. There are a total of six different basic versions available, depending on clients’ requirements. Here is a breakdown.
TU40 and TU45
The Krone Box Liner TU40 can be used universally for containers up to 40 ‘. It is also possible to transport 20’ containers flush with the rear, two 20’ containers, 20’ containers in the centre, tank containers, as well as swap containers. The wheelbase is optimised for a two-axle tractor unit.
Meanwhile, the TU45 Box Liner also has a front extension and can therefore also transport 45-foot containers with a long tunnel.
TU50 and TU55
The TU50 has a longer wheelbase so that it can shoulder 45’ containers regardless of the tunnel length, with a B dimension of 12,775mm. The TU55 is designed with a front extension so that it can also transport 45-foot containers with a long tunnel and B dimensions of 12,000 and 12,150mm.
TU70 and TU75
The TU70 Box Liner has four different wheelbases. This means that when pushed together, it can transport 20’ containers with improved fifth-wheel pressure flush with the rear. In addition, an extra-short wheelbase can be selected for transporting heavy 40’ containers, and 45’ containers can also be accommodated.
Even more flexible is the TU75 with front extension, which is equipped for almost all container types, up to 45’ containers with a long tunnel and B dimensions of 12,000 and 12,150mm.
All Krone Box Liners of the new generation are manufactured from high-strength steel in a central tube design, offering up a combination of low weight and high robustness. As a result, the Box Liner TU40, for example, is launched with an unladen weight of less than 4.5 tonnes.
The range is equipped with the Krone traction rear as standard to maximise the possible payload with a 20’ container, flush with the rear and to achieve the highest possible fifth-wheel load. The traction rear achieves a similar effect to a centre extension, or improves it, if the chassis already has a center extension (TU70 and TU75).
The rear extension of the new Box Liner generation is generally operated with a pneumatic cylinder, which is protected in the extension tube. In addition, the rear extension is always locked pneumatically. A corresponding locking indicator ensures maximum working safety. The taillights are also housed in the rear beam to protect them from damage.
Proof of the special stability of the new chassis generation is the design of the 20’ centre function for 34 tonnes, with tank container suitability. As an option, swap containers can also be transported using locking attachments.
The new TU45 Box Liner is positioned as a promising all-rounder, combining a short wheelbase of 7,470mm with the option of also transporting 45’ containers with a long tunnel. This Box Liner is therefore predestined for use behind two-axle semi-trailer tractors without exceeding the drive axle load with heavy 40’ and 45’ containers. In addition, the TU45 can also be used to transport 45’ containers with long tunnels, while complying with the permissible overall length without the need for a special licence.
