Prolec safety system used in Norwegian rail solution 

Following changes to safety legislation, Prolec's award winning safety systems have been selected by Volvo CE for their customer Mellerud AS.

Last year’s changes in safety legislation for the Norwegian rail construction industry have provided a challenge for plant suppliers required to meet tightened safety standards and an additional requirement for the monitoring of safe load functionality.

Prolec has joined with Volvo CE to provide a solution using its Liftwatch Rail technology for Volvo’s customer Mellerud AS. The ECR 145 delivered to Mellerud AS features a customised version of Prolec’s Liftwatch Rail, a rated capacity indicator (RCI) and envelope monitoring technology, which provides simultaneous height and slew restriction. This customised solution was a collaboration between Prolec and Volvo Maskin, who in turn, worked with Swedish CeDe Group AB in developing the excavator. Liftwatch Rail was chosen as the base product for the solution as it meets all necessary EN regulations and machinery directives. 

CeDe Group AB was in charge of the rail alignment build for Volvo as part of a partnership between CeDe Group and Volvo Construction Equipment Europe. The converted ECR 145 features a number of innovative solutions, including:

  • All four wheels have hydraulic motor operation with a top speed of 20 km/h
  • Stiff shafts with longitudinal mode increases stability
  • The front and rear rail wheel size has been increased to 700mm

Lars - Johan Lackegård, Key Account Manager, Cede AB points out that it used quick fix with hook on fixing to allow the rail solution to be easily removed so the machine can be used in traditional construction. He says,

“If you want to sell machine, you can keep the rail axles and mount them on a new machine, improving the value of a second hand machine as it can be used in traditional construction again.”

Knut Grepperud believes that rail will be an important market in the future for Volvo Maskin. He says,

“I think this is a market we have only seen the beginning of because Rail transport in Norway has been neglected. However, with our new ECR 145, with the system, we are in a strong position to provide our customers with the best possible solution.”

Jürgen Reineke, Sales Manager, Scandinavia, Central and Eastern Europe, Prolec was impressed with the whole set-up, saying,

“I have not seen machines with a good stability and high lifting capacity like this.”
