Must I Purchase a Used Crane?

Buying an overhead crane is definitely an costly decision accustomed cranes tend to be a minimum of regarded as a choice. Clearly it’s a cheaper option at first glance, but could it be really cheaper? Following are a few inquiries to consider.

1. May be the manufacturer still running a business? There has been many consolidations, closures and bankruptcies within the crane industry. Are you going to be capable of getting parts for the crane? Most of the older cranes tend to be more robust and therefore are a built-up design which enables you to definitely buy most of the parts out of the box because of them being industry standard components (NEMA rated for instance). This is applicable for motors, contactors, bearings, and couplings to mention a couple of.

But, most of the cranes have components which were particularly designed for the crane manufacturer and don’t use standard components. You might want to make changes to components to help make the retro-fit parts fit properly. Many crane manufacturers require special motor shafts, contactors, collector footwear, electrification systems to mention a couple of which might or might not be easily available.

2. What exactly are my liabilities basically purchase a crane making any modifications into it? Manufacturer’s liability is totally relieved when you modify their crane. Most used cranes will require some form of re-span which requires major mechanical modifications.

When the crane is particularly old, this area girders might be riveted girders that are hard to modify, or arch beam type on patent track design that have been considered unsafe. Correctly done, an engineer will have to design and set his PE seal any modification to some bridge girder.

3. May be the crane the best convenience of my application? Bigger is usually better in crane applications but you have to think about the costs of having a great deal on the greater than needed capacity? You can find more costs to think about. The crane is heavier and can need a bigger runway and footings to aid the dead load of only the crane. Every substitute part like the motors, brakes, contactors, and wire rope each one is bigger and much more costly to exchange. If you’re making changes or upgrades towards the electrical system for example variable frequency drives individuals components may also be bigger and much more costly.

4. Will the crane match my existing electrical power? There are lots of tales of the customer buying a classic crane after which working out it’s Electricity or even the wrong current. After this you face costly motor changes or step-up or step lower transformers. Is also the electrical delivery system current. May be the electrification old open wire type, or perhaps an obsolete kind of bar? It’s very costly to exchange the electrical with an old crane.

5. Isn’t it time to stop the reassurance of the warranty? Used cranes typically carry no warranty. New cranes now generally include 12 months materials by having an additional year on parts for those non-put on products. There is also current parts manuals so that you can order parts in the manufacturer.

6. Who’ll do my modifications towards the crane? In case your crane does need a re-span or major electrical modification a skilled crane company must be involved. Which side the job be achieved? Do you know the additional costs of shipping including taking lower the crane, shipping to some shop after which reshipping for your facility? Will an expert engineer support all the work? When the crane has problems once it is incorporated in the shop, who’s responsible? Most used cranes are “out of the box”.

There are lots of tales of the good used cranes being rehabbed but some caution and preparation needs to enter place to help make the right decision.
