The tooth types best suited to excavators and loaders are as follows. Tooth profiles according to machine model: excavators and loadersĭepending on the machine model, the tooth profile must offer certain characteristics for good operating performance and efficiency. This has to be limited to avoid overloading the machine and creating situations that could be dangerous for operators.ĭownload a summery table here showing the main terrain characteristics and the most suitable products in each case The first case requires greater impact resistance, while the second requires greater penetration capacity.įurthermore, the higher the material density and specific weight, like for example rock or high water content terrain, the greater the importance of bucket capacity. La terrain class increases in relation to both particle size and density. In general, the higher the terrain class, the greater the required product wear resistance. Penetration capacity and sharpness resilience Impact resistance and durability over time They can thus be divided up into:Īs regards application, the product characteristics that have to be considered to establish whether they are appropriate for the terrain include: Teeth can be categorized by application, which means the type of terrain in which the wearing elements will be used, and the type of machine on which they will be installed. Fitting the wrong profile could result in early tooth wear, breakage after a few hours of use, or the well-known “balling” wear effect rather than remaining sharp.Īpplication and machine model: everything there is to know about choosing the right teeth It is essential to establish the tooth profile since there are specific profiles for each different application. The larger the size, the greater the tearing force to which the tooth-adapter-fixture system can be subjected. The size also provides an approximate indication of the tonnage category of the machine on which the tooth-adapter-fixture kit will be installed. Size is identified mainly by the internal dimensions of the tooth pocket. The size means the dimensions the tooth must have for correct coupling to the adapter. Once the tooth model has been identified, the profile and size must be established Single element comprising steel and rubber parts Elastic steel pin (single element in rolled steel)Ĥ. Single steel element with rubber fixtureĥ. Single steel element fixed with retainerĢ. What elements are used in the fixing systemġ. How the tooth is fitted to the relevant adapterĢ. If it is necessary to choose teeth as well as adapters, it is important to establish the following.ġ. The thickness of the bucket blade in question. Whether the bucket on which the adapters will be fitted is original or after-market. What machine the set of teeth and adapters will be installed on (e.g. To identify the right adapter, it is first necessary to establish: How to identify the most suitable teeth and adapters? In this discussion we will set out the necessary information in order to equip your machine with the right products. The required application also determines the selection of tooth type and profile. Teeth and adapters are distinguished by type, profile, and fixing system when equipping buckets for loadrs, eexcavators, and mini-loaders.
