Cat excavators as heavy-duty machinery branded by industry, the number configuration of their chain boards has been the focus of user attention.In general, the number of chain plates for Cat excavators will vary according to the type and type of aircraft.For example, the Cat320D excavator is usually equipped with 45 chain plates, but the Cat336D excavator may need more chain plates to meet its strong excavator and stability requirements.Therefore, specific to each Cat excavator, the number of chain plates for which the standard configuration is known is based on official configuration tables or consulting professional sales personnel.Understanding and correct use of the number of chains matching the Cat excavator when it is purchased or maintained is essential to improve the efficiency of the equipment, extend its useful life and ensure the safety of the construction.At the same time, the quality of the chain plate is equally important, and the original factory fittings are better able to ensure consistency with the overall performance of the excavator.In summary, there are no uniform answers to the question of “the size of the chain plate of the Cat excavator”, which needs to be analysed on a case-by-case basis and determined by reference to the actual pattern of the vehicle.
