Ten Tips For Standard Crane Buyers

In this article, we would like to use our experience as manufacturers to help standard crane buyers make the right decision on purchasing these vital production assets. Our “TEN TIpsf Or BuyErs” list aseries of minimum precautions to be taken before embarking on this major investment. They are not aimed as a set of instructions for buying, but we hope they will help answer some of your queries.

1. DON'T JUST THINK OF THE COST OF THE CRANE.

It is a strategic mistake to only base your purchase on elements such as the cost of the crane it self and not others such as corrective and/or preventive maintenance over the next few years, as these are just as important. Manufacturers who invest in the durability and reliability of their equipment will realise that they maybe more expensive today... But they’llbe much more profitable tomorrow.

2. TAKE SAFETY INTO ACCOUNT.

Ignoring the crane’s safety elements is a big mistake, and it also has a direct impact on the crane’s working life. The buyer may not need to know about the european safety standard, but he does need to ensure the manufacturer complies with it. Just try this out: ask about the cable’s safety coefficient (it mustn’t be any lower than 5).

3. ASK ABOUT KEY FEATURE

The hook might seem like a mere accessory, but it’s vital to safety as a load hanging element. Ask to see the design of the hook. Many manufacturers are more concerned with design than with hook strength, and their hooks don’t meet the required standards.

4. DON'T FORGET ABOUT MAINTENANCE

All production assets have to be in perfect working order to fulfil their expectations, and the crane manufacturer should therefore recommend preventive maintenance that will extend the working life of the crane. Electronic devices exist today for checking the state of the cranes, their correct functioning and the maintenance requirements that will prevent unwanted problems from occurring. If the manufacturer has provided a robust, tried-and-tested standard design, part replacement will be much quicker, cheaper and efficient.

5. DON'T EXPECT YOUR CRANE TO WORK THAT LITTLE BIT EXTRA

That’s a really big mistake. Over loading the crane endangers its safety and shortens the life of its components. For loads of over 1000 kg a load limiting device is required by law, to prevent temptation. Many manufacturers offer the option of a display showing the weight of the load, which can save you unpleasant surprises.

6. THE DESIGN OF THE SINBLE-GIRDER TROLLEY DRIVE IS IMPORTANT

If the drive is only on one side, the trolley will be subject to cross-stressing that will shorten its lifetime. Make sure the manufacturer provides transmission on both sides.

7. DON'T JUST LOOK AT THE DESIGN FOR DOUBLE GIRDER TROLLEYS

Ask for a jointed frame design that will ensure all four wheels are correctly secured and prevent premature wear.

8. THINK ABOUT THE INCLUSION OF CUTTING-EDGE TECHNOLOGY

Frequency inverters for crane drive improve crane movement control and prolong the life of electrical components, mechanisms, motors, gears, bearings...

9. THINK ABOUT THE INCLUSION OF INNOVATIONS TO IMPROVE SAFETY

Frequency inverters will prevent problems with load swing and inaccurate movement.

10. CHECK THE GEOMETRICAL CONSTRUCTION OF THE CRANE AND ITS ALIGNMENT

A well-manufactured support structure for the crane is vital (camber, pre-camber, squaring, correct wheel alignment, etc.).
