THE STRENGTH OF YOUR MACHINE IS DEFINED BY ITS PIVOTS
SIMPLICITY
Comparison common practices and how assembly, maintenance and accuracy can be improved.
SAFETY
Compare safety risks involved in the assembly, operation and maintenance.
RELIABILITY
The right long-term solution for the prevailing conditions.
LIFETIME COSTS
Minimize regular maintenance, reduce operational expenses and increase production rate.
STRENGTHEN YOUR WEAKEST LINKS
All moving mechanical parts experience wear. Pivot wear is traditionally time consuming to repair.
The challenge of lug wear
Lug wear occours due to the clearance between the bore and the conventional pin.
Uneven wear causing ratteling & low precision
Decreased operational reliability
Line boring is the commonly used method for repair of lug wear:
Can be undesireable to perform offshore
Requires the right season
Downtime including transportation, welding and line boring
Reoccuring wear & repeat maintenance
CONVENTIONAL SOLUTION
Prepare machine
Remove existing pin
Mount equipment (lifting)
Prepare cutting
Rough cut
Prepare for welding

THE MOST RELIABLE SOLUTION FOR HEAVY MACHINERY
The handling and setup of drilling equipment is an extremely important part of the oil and gas industry. The Expander System increases control and precision during setup, while enhancing safety on the rig or extraction site. DNV certified, the Expander System also minimizes maintenance and downtime.
When you’re 400 km from the nearest coast, safety comes first.
SOLUTION USING EXPANDER SYSTEM FROM NORD-LOCK GROUP
The Expander System will fit in a pivot design made for a traditional straight pin. Bolted pivot pin construction, fitted into the bores in its relaxed condition then tightened into the bores with hand tools; safe & controlled process
The patented Expander System has been endurance tested for over 50,000 hours without failure and more than 1 million pivot pins have been installed in over 80,000 applications.
Safety hazards reduced
Patented in 1985, Expander System is a recipien of the Alfred Nobel Swedish Innovation Development Award
