Back in 1952 Gunnebo Industries launched the Coupling G-link. This invention
changed the industry of lifting equipment. Prior to the G-link the standard was
to use all-welded chain slings, an expensive and time consuming process as
each and every chain sling ordered had to be assembled in the chain factory.
With the G-link chain slings could be assembled in local sling shops closer to
customers, creating more effective and flexible processes.
Besides a perfect design the G-link is equipped with a special pin retention
system. The pin has a recession in the middle where the locking bush holding a
helicoil shaped spring lies. The design of the pin, spring, and bush guarantees
safe retention of the locking bush, in case the wire of the spring should break.
Clear markings
• Country of origin.
• Traceability code.
• Model, size and grade.
Safety is our highest priority
• To keep the pin securely in place every
loop of the square shaped wire locking
spring actively creates maximum locking
effect.
• Every part of the locking spring – even if
the wire should break – is still active to
hold the pin
Heavy duty locking bush
• Thick walls and washer protecting the
spring.
• Permanently pressed together in an
automated process, reducing risk of
breakage.
• Square shaped stainless steel spring.
• Elektrogalvanized or stainless steel
depending on model
The special pin
• The pin has a recession in the
center to give maximum locking effect.
• Safe retention of the locking bush.
• The pins are made in an automatic
turning machine.
• Batch and grade marking in the center
