IN FOCUS / COMPONENTS EXCHANGE PROGRAM
MARKET RESPONDS TO COMPONENTS EXCHANGE PROGRAM Crane hire companies quick to respond to the Baden Components Exchange Program. Cranes and Lifting explains. IN THE MAY/JUNE EDITION OF Cranes and Lifting, we highlighted the launch of the Baden Components Exchange Program and how it can help minimise customer down time when components need replacing. Following publication of the article, Ben Baden received a number of positive phone calls. “The article generated a strong response from customers, and in particular the Components Exchange Program. As a result, we have already had the 55t Liebherr telescope cylinder change over twice. “The first time I changed the 55t Liebherr tele cylinder, it was a relatively simple re-chroming job. With this, the customer’s crane would have been down for approximately three to four weeks. We swapped the telescope cylinder out in three days and then overhauled his cylinder. When you factor in the daily hire rate for a 55t all terrain, the customer has saved a lot of money due to the limited downtime of the crane,” said Baden. According to Baden, cylinders can get damaged for various reasons. Damage could be due old age, dirty hydraulic oil or it might be as a result of impact damage. “Cylinders with a bit of age can potentially develop rust areas on the chrome which lifts the chrome from the cylinder, damaging the seals and causing it to leak externally. “In this instance, the cylinder needs to be removed, stripped apart, the chrome rod is inspected for any rust, abrasions or knocks, damage, scratches or marks. The internal barrel of the cylinder is also checked for scoring and occasionally barrels will need to be 42 / CAL July 2020

honed out to bring them back to good working condition. You then get a fresh set of seals throughout and the cylinder is reassembled and bench tested. That’s pretty much the cylinder repair process. “The cylinder repair process can be as simple as stripping the cylinder apart, finding everything just needs to be cleaned and polished, a new set of seals fitted and its put back together. That’s the best-case scenario and your quickest fix and turn-around time. Depending on your cylinder repairer, that can happen within one to two weeks,” said Baden. The next level of repair is when the rod needs to be chromed. It goes through a process where the old chrome is stripped off it before it can be re-chrome plated. After it is re-chromed it is linished and then re-assembled. If the barrel has internal damage, the barrel will need to be honed says Baden.
“In worst case scenarios, we have cylinders that come with damaged barrels. Either the barrel is cracked through or has been over-pressurised and expanded or they have been bent in an accident. These are the most time consuming and expensive of the repairs. “The only way to do a proper repair is to remanufacture the barrel completely and for that you are looking at a four to six-week turnaround, as long as the materials are available. If the material isn’t available in Australia, which occasionally it isn’t, it can be three to four months to fabricate a barrel. The other option is to purchase a new cylinder from the manufacturer,” said Baden. “We’ve turned one 90t telescope cylinder over where it was a relatively simple process and it only required re-chroming. But the second time we sold that telescope cylinder, it was to a customer who had a cracked barrel. Again, his crane was only down for a few days during the change out process. “The important point about the exchange program is the time spent to repair that cylinder is not down time for the customer’s crane. Generally speaking, we can get the crane back in service within a few days rather than weeks. It’s then ‘my own time’ to repair the cylinder in my and have it ready to go when the next customer might need that cylinder,” he said. Baden says he doesn’t often source new cylinder pricing but occasionally a customer will, and they find that new cylinder pricing is generally high. Then the cost of shipping has to be factored in, on top of the cost of the new cylinder, which makes it a costly exercise. www.cranesandlifting.com.au
