Bottom Dumper

Description

Fast loading and unloading are key features of the Bottom Dumper, which is an 8-axle wagon made up of a master wagon and a slave wagon. The bottom of the wagon consists of two large hatches that open entirely during discharge. Emphasis has been placed on the angle of repose, to optimise the centre of gravity and achieve a complete emptying. The wagon is designed for rolling discharge and has a discharge capacity of up to 20,000 tonnes per hour.

​

The solution and its components are tested and proven in a demanding subarctic climate; Kiruna Wagon’s Bottom Dumper is currently in traffic in the Arctic regions of Sweden and Norway. The Bottom Dumper unloading station is a low-cost solution designed to provide a reliable service in temperatures ranging from −40 to +60 °C.
