Construction
One foundation has been to make the wagon production-friendly by, among others, the use of a chassis with a central girder. This creates room for a lowered tare as well as more effective production. Minor modifications on a pure central girder solution have been necessary. Consideration has also been taken to preparing for the second generation of this wagon, especially applying to a central automatic clutch, disc brakes, articulation and flexible placement of the basket’s attachment points on the frame.
Wagon-mounted hydraulics is limited to the roof opening, with air and hydraulic pipes being drawn into the central girder of the chassis. The roof is opened through connection to power points at the loading station.
For discharge, the wagon is locked in the correct position before external lifters connect to the basket and tip it to an angle of 55 degrees. The opening of espagnolettes and hatches is mechanically integrated in the tipping function. The roof is kept closed during the entire emptying process.
Tipping can be done both to the right and left.
For framework, frames and profiles, high-strength steel is used to limit the tare.
Maintenance
The bogie construction is a solution that saves maintenance time such as when servicing brakes.
The wagon is otherwise designed for easy change of wear and tear components such as links, bushings and rubber seals. Even larger parts such as hatches and espagnolettes are constructed and dimensioned in such a manner to be easily unhitched and changed.
A subarctic climate influences the choice of materials, and we are proud of our close cooperation with SSAB. A world-leading supplier of high-strength steel.
The calculated lifetime of the concentrate wagon Aiktik 36 Pendeln is 30 years.
