THE FASTEST UNLOADING OF STICKY BULK MATERIALS
Helix Dumper unloading in Narvik, Norway, for Northland Resources.
Kiruna Wagon’s Helix Dumper is the wagon of choice for small fractions and tough-flowing commodities that are unsuitable for bottom discharge. The HD unloads even the stickiest materials at rates up to 25,000 tonnes per hour. Currently, there is no technology that can match its productivity when it comes to unloading heavy fine-grained bulk at a high discharge rate. The discharge process is powered by the locomotive’s forward motion and the robust and simple HD unloading station requires no additional power supply. Both the wagon and unloading station are manufactured by Kiruna Wagon.

HELIX DUMPER
Lightweight wagons Rounded shape for efficient discharge Low-cost unloading station Continuous discharge Tipping by train engine No moving parts
NO MOVING PARTS – NO ELECTRICITY The Helix Dumper unloading station is a robust and low-cost solution that requires minimal maintenance. When the Helix Dumper enters the unloading area, a wheel at the top of the wagon makes contact with the spiral-shaped rigid guide that constitutes the unloading station. As the wheel travels along the path of the guide, the chassis remains on the rails while the body of the wagon is rotated 148 degrees to dump its load. The discharge process is powered by the locomotive’s forward motion – the Helix Dumper unloading station has no moving or motorised parts and requires no additional power supply.
BEST CHOICE FOR FINE-GRAINED BULK Currently, there is no technology that can match the productivity of the Helix Dumper when it comes to unloading heavy fine-grained bulk goods at a high discharge rate. Bottom dump systems operate at a fast rate but can’t handle sticky materials, and rotary car dumpers are slow and expensive compared to the rolling discharge solution of the Helix Dumper. The Helix Dumper unloading station is delivered with principle drawings and a maintenance program. Kiruna Wagon will perform the installation, supervise the start-up process and train the operators.

A shallow pit requires a lower investment and less energy for material reclaim and handling
Through efficient unloading as a solid train in continuous motion, the Helix Dumper can greatly reduce your unloading times and maximise your wagon utilisation.
26.1km/h
AVERAGE ANNUAL WAGON SPEED At Kiruna Wagon, we consider average annual wagon speed, AAWS, to be one of the most important key performance indicators. In the authentic case of Kaunis Iron’s ore transports from northern Sweden to the Port of Narvik in northern Norway, the HD system is designed to operate at 26.1 km/h AAWS. The AAWS of our BD wagons for LKAB is 17.5 km/h, while our BD wagons for Rana Gruber operate with an AAWS of 25.7 km/h. On our website, you can download our AAWS Calculator and compare with the numbers of your own fleet.
World Class Ore Logistics
We deliver both the wagons and the unloading station When you buy a system from Kiruna Wagon, you acquire a complete solution for both transport and unloading. We consider the whole logistics chain and design systems for efficient transport at the right total capex and opex. We are one of very few companies to deliver both the wagons and the station.

The low-cost unloading station facilitates increases in production and high scalability
7450
If the future brings increases in production, the HD system can easily be scaled up with one or more additional unloading station. Thanks to its limited construction depth and lack of electric motors, the HD unloading station requires a smaller initial investment than, for example, rotary car dumpers.

SPECIALLY DESIGNED BUCKET FOR GENTLE UNLOADING BY EXCAVATOR The body of the Helix Dumper has a rounded shape for efficient discharge of fine-grained commodities. For situations where unloading by excavator is required, we have developed a rounded bucket that can unload the goods efficiently without damaging the body.
