Each time machinery is inactive at a mining site, there is a loss incurred in production. However, the majority of breakdowns of excavators, rock breakers, and backhoe loaders can be attributed to the same reason- an unavailable or worn-out component that could have been proactively replaced. That is exactly the reason why procurement teams, contractors, and fleet owners have a list provided by the earthmoving spare parts manufacturers. It is to make sure that every important spare part has been arranged before the project starts.
Whatever the size of your fleet is, be it an individual excavator or a fleet of various mining and construction equipment spread over several locations, this list of spare parts will provide you with information on what should be checked and stocked, including spare parts for every type of machinery.
Excavator Spare Parts
Excavators are the most heavily used type of earthmoving machines, and their common points of wear are known even to the inexperienced operator.
Pins and Bushes
At any joint, buckets, arms, and booms generate constant friction thanks to pins and bushes. If the clearance exceeds the manufacturer’s tolerances, you need to replace them both because if they are mismatched, wear will accelerate failure of the new part.
Collar, Step Collar, and Lock Collar
The joint features smaller elements that hide from view until rattling of the joint occurs. A worn collar lets dirt and moisture into the joint and reduces the life of surrounding components.
Undercarriage and Stick End
The undercarriage bears the weight of the machine and absorbs shocks from the uneven surface. The stick end/arm end connects the digging assembly to the boom, and cracks and excessive wear in that area highly influence the accuracy of the digging process.
Rockbreaker Spare Parts
The operation of rock breakers involves continued hits, resulting in the more frequent wear of the components in comparison to other kinds of equipment.
Chisel, Chisel Lock, and Piston
The chisel, when worn, will transmit pressure to the piston and surrounding housing. The chisel lock pin performs the function of keeping the chisel in the proper place, so fix any slackness in this area.
Bush Set, Stop Pin, and Through Bolts
The bush set protects the chisel by absorbing lateral shock and must be replaced as a whole set because the alignment must be even.
Pins and Rear Axle Shaft
These are backhoe loader spares. The wear on backhoe pins is identical to that of excavator pins and therefore needs to be checked on the same timetable. The rear axle shaft, on the other hand, should be carefully looked at because it is responsible for carrying both drivetrain load and digging pressure; pay heed to any strange sounds when moving and be on the lookout for any play at the joint. When it comes to finding trustworthy Earthmoving Spare Parts manufacturers for this part of the equipment, one needs to be more careful than in many cases since the failure of the axle shaft can stop the machine from working completely, not just slow it down.
Conclusion
The most effective way to ensure the uninterrupted functioning of excavators, hammer mills, and diggers, without surprises, is to have authentic spare parts handy. If you are making your inventory list, it is easier to maintain it if you work with the earthmoving spare parts manufacturers who offer a complete line of pins, bushes, collars, chisels, pistons, and axles. Axle Shaft India is one such manufacturer with all the spare parts for mining and excavation operations.
FAQs
Q. What are the causes of earthmoving spare parts failure?
Dirt and moisture contaminate and damage the sealing of bushings and collars. This causes the spare parts to fail prematurely.
Q. Is it better to stock spare parts in advance?
Earthmoving spare parts are subjected to high wear. Hence, it is advised to keep a stock of them in advance.
Q. Should worn pins and bushes always be replaced together?
Yes, because replacing only a pin or a bush would mean that one of them will rust or corrode faster than expected due to contact with the older part.
Q. How do I know if a part is genuine or a duplicate?
Genuine parts have clear documentation, uniform and consistent surface finish and match the dimensions listed on paper.
