Yes, you can teach
an old dragline new tricks.
“We need to try something new.”
A customer’s request for help showcases the many ways our wear parts
can make a difference.
| CUSTOMER CONCERN | COLUMBIA SOLUTION | FIELD RESULTS |
|---|---|---|
| Outmoded dragline rigging with high failure rate on wear parts. | A modern rigging package, based on onsite consultations and attention to customer needs. | Increased uptime due to superior strength of cast wear parts vs. antiquated fabrications and inferior alloys. Improvements include integrally cast XtraLife® hoist and drag chain, with greater contact area and abrasion resistance. |
| Heavy weight of assembled rigging package. | Consolidated parts and more efficient designs to reduce overall rigging weight. | Lowered overall rigging weight allows customer to increase tonnage of product in bucket. Improvements include 12-hole hoist links, which efficiently consolidate conventional hoist clusters. |
| High turnover rate of teeth and adaptors on bucket, requiring teeth changeout every month. Significant time spent by customer applying aftermarket overlays to teeth, since OEM-style product did not come with hardfacing. | Teeth and adaptors cast in Columbia H series alloy and hardfaced with Columbia Xtend Process® in the foundry prior to shipping. This removed extra steps by customer to obtain overlays, and provides a superior hardfacing and annealing process done in a controlled manufacturing procedure. | Customer has gone from replacing teeth monthly to every 4 to 5 months, a nearly 5-time increase in wear life which means less maintenance, less down time. |
| Loss of pins in connecting links. | Provide reliable mechanical locking design and standardized pins. | Thanks to through-hardened cast pins combined with Xtralloy® bushed parts, versus OEM fabricated or welded pins, a minimum of double the wear life is anticipated. Columbia’s mechanical pin systems speed up installation of links, clevises, sockets and spreader bar ends. |
| No backup wear parts available when needed. Customer must keep own warehouse stock and accurate count to prevent delays during maintenance. | Columbia opened warehouse and agreed to stock customer parts as a backup to their inventory. | Customer has peace of mind that wear parts will be available for rigging maintenance. |
