The crawler crane has long been considered the most common and practical type of crane to restore.  They have a very long useful service life and depending on the make and model, parts and components are still readily available.  While technology continues to evolve, the old conventional crawler cranes continue to provide safe and dependable service.  Developing a plan to extend the working service life can bring you a good return on your investment.  But, before you can make an informed decision you should consider all of your options including the cost of replacement and benchmark them against each other and your budget.

Here is a short punch list of things to think about when considering a project to extend the service life of your crawler crane:

Eliminate Replacement Options:  If you are even considering a restoration project then you have probably already eliminated the option of buying new.  But, you may be thinking about looking around for a more current used crane.  Before considering replacing any crane that has provided you with several years of exceptional service you should consider a restoration.  You may find out that you already have the best used crane out there.  So, why not find out what it would cost to extend the productive service life of your current crane?

If you are looking to take the project on yourself make sure you have a complete and comprehensive plan.  While many crane owners are fully capable, it takes a full time commitment to assure it doesn’t end up becoming a part time project and costing you more than you expected.  Remember, the object is to get the crane back into revenue generating service in the most time and cost effective manner.  Even if you think you want to take it on you should get an estimate from a third-party repair and restoration services provider to benchmark your plan.

Make/Model/Market:  The past 20 plus years there has been a lot of industry consolidation.  Names like Lima and Northwest have virtually disappeared leaving them with little to no market value and may not be worth the investment to restore.  On the other hand crawler crane manufacturers like Manitowoc, Link-Belt, Terex/Demag/American, Liebherr and Kobelco are recognized brand names whose products hold value and are great candidates for service life extension projects.  It is still a good idea to take a look at the particular model you are looking to restore and consider the popularity of that crane.  If it is, or was a popular model like the Manitowoc 4100 or 888 it makes for an easier decision.  On the other hand if it was a less popular model or size then you may want to reconsider a decision to restore.  The value can be diminished by the availability of the manufacturer or market to support the product.  Or, it simply may not be a very marketable crane if someday you need to dispose of it.

Application:  Application can play a big part when deciding whether to restore your crane.  There are a lot of unique applications out there that suit particular makes, models and sizes of cranes.  If you can’t improve on the situation then we wouldn’t suggest that you try.

Condition:  The condition, particularly of the boom and major weldments will have a major impact on your decision.  The boom, car-body, side-frames and superstructure should either be in tact or reparable.  Larger replacement weldments are often difficult to find. Having one made new is generally cost prohibitive or may add significant costs to the project.  The after-market may provide an opportunity to find used components but it can also be an expensive and challenging process to locate them.  And when it comes to used boom we never recommend you buy used unless you know its’ complete history.  It is much better to have an engineered and documented repair of your existing boom.

Technology:  Despite the evolution to full hydraulic control systems, turntable bearings and full electronic LMI systems we still see a lot of crane owners restoring the older cranes.  The old “friction rigs” are often still preferred because they can easier and more cost effective to maintain.  And, there are several after-market providers of A2B and LMI systems that can be fitted to upgrade the older cranes.

Developing a Roadmap: Once you have determined that your crane is suitable for restoration, you will need a good cost estimate.  This requires a thorough survey and inspection that will help you to develop a comprehensive scope of work.  A properly developed scope of work will allow you to put a good price estimate on the project.  You also need to anticipate what else you may find when you disassemble the crane.  No matter how thorough the survey you cannot expect to see everything until the unit is disassembled.

Down Time: How long are you going to be without your crane?  Do you need to rent another unit until the project is done?  This can have a significant financial bearing on your decision.  And there can be a difference in how long you planned on being down versus actual downtime.  Be sure to plan accordingly.

Vendor Capability:    Restoration projects by their nature are challenging.  You need to understand if the service provider can provide you with a turn-key project.  Facilities, tooling and a controlled environment are critical to a quality restoration.  Additionally, the company that repairs your machine should have qualified technicians, processes and best practices in place that provide for a safe, compliant and documented restoration.

Remember, information is knowledge and knowledge is power.  Let WHECO help you develop a scope of work that will extend the useful service life of your crawler crane!

    Jay:
    Nice article.

  2. Several crane hire customers of mine have refurbished and restored some older lattice boom and crawler cranes. In some cases they have also upgraded the cranes. Especially the old Gottwald cranes are really thankful objects for these procedures. They were built very massive and offer much reserve in load capacities. As far as I can judge, this must be a perfect way to increase revenues of the crane. The crane is fully paid and can earn money for several more years after restoration. Even more with an upgrade in load capacity.

    P.S.: Nice work you have done so far!
