Pick any of the world’s most exciting motor races and you will find the orange motorcycles by KTM, Europe’s largest manufacturer, among the top contenders.

Located in Mattighofen, Austria, close to both motorsport-crazy Italy and R&D stronghold Germany, KTM mixes influences from both countries with its own “never give up” attitude. After failing to cross the Dakar finishing line ten times, KTM turned failure into a winning streak that has lasted since 2001.

KTM is the only manufacturer that bolts the gearshift lever axially instead of clamping it, making it easier to access with tools. However, the bolt that attaches the conic gearshift lever to the shifter shaft was a weak spot on early pre-series bikes. Heavy washers combined with glue couldn’t prevent loss of preload during some of the most extreme jumps, where the riders land with their foot on the gearshift lever. The whole lever would come loose.

Standard Nord-Lock washers were either too large or too thick to solve the issue. However, Nord-Lock customized an NL6sp washer, with an outer diameter of 16.6 mm instead of 13.5 mm. Two years later, KTM hasn’t seen one single case of gear-lever bolt failure.

Irish Rail safely secured with Nord-Lock washers

Safety is everything for the Irish Rail. When they noticed that the bolts on their axle boxes were loosening due to vibration, they decided to replace the locking-wire mechanism on the wheel sets with Nord-Lock washers.

“Since the introduction of the Nord-Lock washers we have not had one instance of a bolt coming loose which give us a lot of comfort from a safety point of view”, says Conor Doyle, Senior Fleet Technical Support at Irish Rail.

Two years on since the first installation of Nord-Lock washers and Irish Rail has been more than satisfied with the outcome.

Green technology for sustainable land clearing

Customer: Gyro-Trac
Market share, North America: 60% for mulching machines
Location: Factory in Quebec, Canada. HQ in South Carolina, USA
Products used: NL3/8″ & NL 20 washers
Applications: Mulching machines, bio-energy balers

The importance of sustainability in land clearing is reflected in the product range of North American company Gyro-Trac. With a 21-year history of manufacturing mulching machines, its focus is now also on creating bio-energy balers for easy packaging, transportation and storage.

As the mulching machines clear unwanted trees, this green technology leaves soil structures intact, eliminates erosion and run-off pollution. The machines can mulch trees to the ground, leaving the roots of neighbouring trees undamaged.

Nord-Lock has provided high-quality wedge-locking washers to Gyro­-Trac for around 15 years. The washers maintain the balance of their mulching machines, extending the life cycle and sharpness of the teeth in the process.

The washers also play an important role in Gyro-Trac’s Bio-Baling System. The system involves compressing biomass in such a way that no compost is created and no burning is required. For Gyro-Trac’s customers, the added costs of hauling and dumping are eliminated, while onsite storage of the one-tonne bales promotes sustainable land use.

Daniel Gaudreault, owner of Gyro-Trac, says: “The teeth are the heart of the machines we produce. We have never had a problem with Nord-Lock washers and their reliability has been vital to our continued success.”

Video: Step by step – installing Superbolt Expansion bolts

Installing Superbolt Expansion bolts at EDF hydro electric power station

First published in Bolted #1 2017.

Don’t miss the new Nord-Lock Group video that focuses on the hands-on aspects of our Expansion bolt technology.

The video takes you through an entire Superbolt Expansion bolt installation process, from preparation and positioning to the fitting of the bolts into the holes when aligned.

The video was filmed on location at the EDF hydro electric power station, Usine Électrique de Malgovert, in the beautiful French Alps, where electricity generator giant EDF joined forces with the Nord-Lock Group to install Superbolt on the Malgovert turbines.

“EDF chose Superbolt Expansion bolts to simplify future maintenance. Ease of installation and removal due to the expanding sleeve technology insures against future damage to coupling bolt and coupling holes. There is no longer a need to re-machine holes or replace bolts,” says Steve Brown, expansion bolt specialist with the Nord-Lock Group. “This film is for everyone who wants the optimal bolted coupling, using and making the most of a Superbolt installation.”

 

The new issue of Bolted digs deeper into the best way of tightening a critical bolt!

The March issue of Bolted magazine will be hitting the desks soon! As usual we invite you on a journey to explore interesting cases and insights from the world of bolting.

This edition’s theme article revolves around hydraulic torquing and tensioning. We play off one against the other in an attempt to answer which is the best method of tightening critical bolts.

In the process of creating this issue we have talked to many satisfied customers from around the world! We will take you to Nuremberg where we have a closer look at a better and more cost-efficient way to renovate track beds in their railway underground system, without weeks of construction and chaos caused by delays and diversions.

This issue also features sustainable mulching machines exposed to extreme vibration, KTM sports motorcycles solving issues with customized Nord-Lock products, and a customer who creates waves with a special buoy as a source of renewable energy.

At the same time we are glad to inform that this edition is also available in Spanish! Bolted magazine is now published in 9 languages: English, German, French, Swedish, Finnish, Japanese, Chinese, Korean and Spanish.
