Protected quarry buckets

The productivity of the quarry buckets of Kestotec is based on an ensemble that works. The ensemble consists of a tough and light frame and comprehensive protection. By combining these things, we have produced the lightest and most durable bucket on the market.

The significance of the weight of the bucket product in terms of costs

Excavators carry out hundreds of thousands of digging and feeding movements in a year. How much weight there is at the end of the boom of the machine directly affects the fuel consumption of the machine and the working life of the wearable parts. A bucket product that is too heavy is expensive to use because it increases the usage costs of the machine.

Kestotec’s buckets save on usage costs because they are lighter than those of their competitors. A Kestotec bucket is the result of up-to-date design and strength calculation and its overall mass is typically 500-1000 kg less than that of its competitors while having the same capacity.

Annually, this means avoiding moving 100,000-200,000 tons of ‘empty weight’. If the fuel costs of a ton moved are known, for example, it’s easy to work out the savings.

Protecting the bucket well can save on repair costs

Kestotec is a forerunner in bucket protection. In Kestotec’s buckets, all the areas prone to wear are protected with separate protection components.

The task of the protection is to:

  • Protect the frame of the bucket from wear
  • Direct the wear to easily replaceable components

No expensive complete overhauls – quick and easy maintenance

Thanks to protection, roughly a half of repair costs for the bucket can be saved on an annual basis. This is because it’s not necessary to carry out expensive basic overhauls and the replacement of individual wearable parts is quicker and easier. The wearable parts are made from harder materials, which increases their working life and thus the interval between repairs is also lengthened in comparison with traditional solutions.

Protecting the bucket saves time and money, because the protection eliminates the wear on the frame of the bucket. Expensive basic overhauls become a thing of the past and repairs are quick and easy to carry out.

The right choice of bucket maximises the productivity of the machine

The performance figures and productivity calculations given by different machine makers for their excavators are based on the whole formed by the machine and its accessories. The bucket plays an important part in this whole. If the machine is fitted with a bucket that is too large and heavy, the fuel consumption of the machine increases, the breakout force of the bucket decreases and the durability of the wearable parts of the excavator is reduced. As a result of the wrong kind of bucket, the performance figures and productivity targets given for the machine no longer apply. The usage costs of the machine increase significantly.

In addition to the weight and capacity of the bucket, attention should be paid to the material that is excavated and its abrasiveness. For this reason, there are several sizes of buckets with different kinds of protection against wear for the same machines in their manuals.

The buckets of Kestotec are designed taking the productivity of the machines, fuel consumption and the earth of Finland into account. They are made for handling Finnish spoil. The capacity of the buckets has been maximised by developing a new kind of construction that is lighter and more durable which enables more handled material to be moved with one scoop. At the same time, this saves on fuel costs. The buckets are durable because the heavy wear is directed at the protection of the bucket, not its frame.
