Last week at the Fastener Fair 2017

We had a great time at last week’s Fastener Fair in Stuttgart!

This international leading trade show, held once every two years, attracts thousands of visitors from the industry and we would like to thank everyone who stopped by our booth!

We took this opportunity to launch our Lifetime Warranty program, and to share other exciting news from the Nord-Lock Group such as extended temperature range for usage of the steel washers, or introduction of our innovative tensioner VersaTite.

We are looking forward to being your trusted partner in safe and efficient bolting and hope to see you at the next trade show!

Green technology for sustainable land clearing

First published in Bolted #1 2017.

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.”

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.

Easy installation of Expander System makes lives easier

Stora Enso focuses on providing renewable solutions in packaging, biomaterials, wooden constructions and paper globally. The company has realized the benefits of the Expander System’s unique solution and mounted Expander pivot pins on their packaging machines where the pivot wear was extensive.

The result was prolonged life span of the machines and no downtime due to pivot wear.

‘We use the Expander System because it is easy to install.’ – says Lennart Larsson from the Hydraulics department at Stora Enso.

The pivot pins are installed directly into the existing mounting without expensive and time-consuming welding and line-boring. ‘These pivot pins mean less wear and definitely made our lives easier’.

Hydraulic tensioners for compact flanges

Boltight’s Xtra Load range of bolt tensioners is used extensively in the offshore oil and gas industry for bolting compact flanges.

The 1500 bar system delivers 30% more load than Boltight’s standard range in a smaller space envelope without compromising on safety, reliability and accuracy. This lightweight and innovative design was developed to suit all common sized ANSI, API and Norsok L005 compact flanges.

Expander System saves a day of work

Gamleby Forest is a logging company with a number of harvesters in their fleet. The machines generally operate year round and eliminating expensive downtime is always a priority at Gamleby.

Upon inspection of one of the harvesters, the machine operator discovered a wear in the lugs between the boom and pillars. The owner of the company, who often does repairs himself, had some experience with the Expander System in the past. He immediately decided to replace the original pin in the harvester with the Expander solution.

The whole replacement process took merely two hours. The Expander solution was installed directly into the worn lugs. The double-sided locking on the Expander pivot pin provided increased stability, security and minimized wear in the joint.

If Gamleby Forest chose to use a new original pin instead of pivot pin from Expander, they would have to transport the harvester to their workshop to mount the pin there. Practically a whole day would be required to complete the replacement. A traditional repair, moreover, would only solve the problem for the moment – wear would occur again.

After the replacement the harvester was back in the operation within a couple of hours and Gamleby Forest became yet another satisfied customer of the Expander System.
