Constant market stresses on civil engineering contractors and tight deadlines, lowering labor prices, impose on any serious entrepreneur to seriously consider all aspects of optimizing their business.

Certainly, one way to achieve greater competitiveness in the market is to reduce operating costs. In order to keep these costs to a minimum, unfortunately, many contractors are starting to think about seriously reducing the cost of maintaining the machinery. Recklessness and insufficient thinking can result in exactly the opposite effects: frequent break downs of machines and tools and the occurrence of unexpected major accidents, sometimes even a complete breakdown of the machine.

The large supply of spare parts on the market on the one hand creates a choice but on the other hand creates confusion and uncertainty. Choosing the cheapest bidder is most often, in the long run, the wrong choice.


What happened in the hydraulic hammer spare parts market?

The fact is that in the global market, the economic crisis has taken its toll - manufacturers of original spare parts were forced to lower their prices, which inevitably resulted in a reduction in the quality of original spare parts. On the other hand, the demand for cheaper parts has enabled the development of spare parts manufacturers that have maintained affordable prices while increasing quality.

Are the original parts always better than the replacement ones?

Most often yes, but not always and not for all parts. Manufacturers of original spare parts do not always produce everything in their factory but use external suppliers with a high degree of output and input control. In the global market, a good retailer can find exactly those same external suppliers who are willing to offer parts very close to the quality of the original at very competitive prices..

How to decide what to buy: original or replacement parts?

A reliable retailer should objectively suggest to their client what is optimal for installation based on their experience. If the hammer is used occasionally and not for large projects, replacement parts can significantly reduce costs and keep the hammer in working order. Those entrepreneurs who use hammers as their primary tool should use original parts.

If I opt for replacement parts, do I buy all the replacement parts or combine?

Each hammer model has some specifics and it is not always advisable, regardless of the price, to install replacement spare parts. It usually pays to use replacement: gasket sets, rubber and plastic parts / shock absorbers and guides, tool bushings, working tools. Replacement pistons and tie rods are risky with large hammers while small hammers have shown acceptable qualities.

Never combine replacement and original parts of the same group: eg always use all tie rods or original or replacement - never a combination.

What I need to watch out for when installing replacement parts?

No matter how good the spare parts are, they are replacement, they are cheaper and therefore their quality is lower. Also, the quality of the finish and the precision of the workmanship is lower than the original parts. That is why it is very important for the user to be aware of these facts - the hammer is less tolerant of operator errors, lack of lubrication, possible cracks in the tie rods, etc. The hammer with replacement spare parts should be inspected more regularly (daily and weekly field inspections). Service intervals are more frequent and should not be skipped as there is an increased risk of major accidents. With the right approach to maintenance, real savings can be achieved because the lower price of spare parts ensures greater savings than the cost of more frequent service intervals. It is clear here that hammers that strike large construction sites and do not suffer more frequent service intervals must use only original spare parts.
