Do excavators need routine maintenance? How to do it?

Excavator bucket is an important part of excavator. Excavator bucket is the most used accessory besides some specific working occasions. But compared with the main parts of the excavator, such as the engine, hydraulic system and so on, the excavator bucket with simple structure often does not get too much attention from the users. Does the bucket really need not be maintained? The answer is, of course, No.

Excavator bucket can be divided into dozens of different types according to the different material and function. In daily work, selecting the right bucket can achieve the desired effect in construction efficiency or cost control.

So how do we maintain the excavator in our daily work?

Most people think that the bigger the excavator bucket, the higher the construction efficiency or the thicker the excavator bucket, the longer the durability, and then blindly reinforce the excavator bucket.


This method is not advisable. If the bucket is protected in an all-round way, the weight of each bucket will be increased. Heavy bucket will not only increase the oil consumption of the machine, but also have a considerable impact on the life of the machine, which can not be ignored. In fact, in general, the manufacturer's standard buckets are reasonably constructed and designed, which can fully meet the general working conditions. If the conditions are really bad and need to be strengthened, it is also recommended that you should weld the parts that need to be strengthened most, rather than the whole welding, do not wrap the excavator with thick armor.


Bucket teeth are the terminal of excavator. Bucket teeth are the most loaded working parts during excavation. They belong to consumable parts. Especially in stone construction environment, the wear rate of bucket teeth is very fast. The use of bucket teeth can also directly affect the efficiency and production cost of excavators. Imagine that when the wear of the tip of bucket teeth is more serious, the force needed for excavators to cut in during excavation operation will be greatly increased, resulting in greater fuel consumption and affecting work efficiency. Therefore, it is necessary to replace the new bucket teeth in time when the loss of bucket teeth is serious.

In the daily maintenance of excavators, if you can check the fuel, lubricating oil, water and air every day, you can reduce the machine failure by 70%.If you want your excavator to do a better job in your daily work, spend 2 minutes a day checking the bucket. The main inspection contents are: the wear degree of the bucket body and whether there are cracks. If the wear degree is serious, the reinforcement should be considered. As for the bucket body with cracks, welding repair should be carried out in time to avoid increasing the length of cracks due to delayed maintenance, resulting in unsustainable situation. In addition, the bucket teeth should be kicked with the foot to check whether the bucket teeth are stable. If the bucket teeth are loose, they should be tightened immediately.


Maintaining the bucket teeth of excavators can increase construction efficiency, control construction cost and create economic value. Our company has many years of casting and processing experience, can provide a variety of Engineering Machinery Accessories, welcome to inquire.



  • What is 'multiple certification'?

    This is where a batch of steel meets more than one specification or grade. It is a way of allowing melting shops to produce stainless steel more efficiently by restricting the number of different types of steel. The chemical composition and mechanical properties of the steel can meet more than one grade within the same standard or across a number of standards. This also allows stockholders to minimise stock levels.

    For example, it is common for 1.4401 and 1.4404 (316 and 316L) to be dual certified - that is the carbon content is less than 0.030%. Steel certified to both European and US standards is also common.

  • What surface finishes are available on stainless steels?

    There are many different types of surface finish on stainless steel. Some of these originate from the mill but many are applied later during processing, for example polished, brushed, blasted, etched and coloured finishes.

    The importance of surface finish in determining the corrosion resistance of the stainless steel surface cannot be overemphasised. A rough surface finish can effectively lower the corrosion resistance to that of a lower grade of stainless steel.

  • Can I use stainless steel at high temperatures?

    Various types of stainless steel are used across the whole temperature range from ambient to 1100 deg C. The choice of grade depends on several factors:

    1. Maximum temperature of operation
    2. Time at temperature, cyclic nature of process
    3. Type of atmosphere, oxidising , reducing, sulphidising, carburising.
    4. Strength requirement

    In the European standards, a distinction is made between stainless steels and heat-resisting steels. However, this distinction is often blurred and it is useful to consider them as one range of steels.

    Increasing amounts of Chromium and silicon impart greater oxidation resistance. Increasing amounts of Nickel impart greater carburisation resistance.

  • Can I use stainless steel at low temperatures?

    Austenitic stainless steels are extensively used for service down to as low as liquid helium temperature (-269 deg C). This is largely due to the lack of a clearly defined transition from ductile to brittle fracture in impact toughness testing.

    Toughness is measured by impacting a small sample with a swinging hammer. The distance which the hammer swings after impact is a measure of the toughness. The shorter the distance, the tougher the steel as the energy of the hammer is absorbed by the sample. Toughness is measured in Joules (J). Minimum values of toughness are specified for different applications. A value of 40 J is regarded as reasonable for most service conditions.

    Steels with ferritic or martensitic structures show a sudden change from ductile (safe) to brittle (unsafe) fracture over a small temperature difference. Even the best of these steels show this behaviour at temperatures higher than -100 deg C and in many cases only just below zero.

    In contrast austenitic steels only show a gradual fall in the impact toughness value and are still well above 100 J at -196 deg C.

    Another factor in affecting the choice of steel at low temperature is the ability to resist transformation from austenite to martensite. 

  • Is stainless steel non-magnetic?

    It is commonly stated that “stainless steel is non-magnetic”. This is not strictly true and the real situation is rather more complicated. The degree of magnetic response or magnetic permeability is derived from the microstructure of the steel. A totally non-magnetic material has a relative magnetic permeability of 1. Austenitic structures are totally non-magnetic and so a 100% austenitic stainless steel would have a permeability of 1. In practice this is not achieved. There is always a small amount of ferrite and/or martensite in the steel and so permeability values are always above 1. Typical values for standard austenitic stainless steels can be in the order of 1.05 – 1.1. 

    It is possible for the magnetic permeability of austenitic steels to be changed during processing. For example, cold work and welding are liable to increase the amount of martensite and ferrite respectively in the steel. A familiar example is in a stainless steel sink where the flat drainer has little magnetic response whereas the pressed bowl has a higher response due to the formation of martensite particularly in the corners.

    In practical terms, austenitic stainless steels are used for “non-magnetic” applications, for example magnetic resonance imaging (MRI). In these cases, it is often necessary to agree a maximum magnetic permeability between customer and supplier. It can be as low as 1.004.

    Martensitic, ferritic, duplex and precipitation hardening steels are magnetic.
