For loaders, each equipment manufacturer has its own system and spacing, and the spacing varies from model to model within a given manufacturer’s product, depending on the size. This means that the rim is unique for almost every manufacturer and model.
Loader rims and segmented bolts have the largest selection and are one of our most frequently customised products. Because the bottom of the bucket is virtually undisturbed, the possibilities for customisation are almost endless.
The straight bucket system offers great flexibility and is designed to accept bolts on rims or teeth and segments. The bottom edges are drilled so that the machine can be quickly converted from one system to another without any welding.
Bolt-on edge systems offer maximum protection for the base edge and are ideal for applications where penetration is not an issue. They also keep the floor smooth and clean and increase bucket capacity. The bolts on the edge are easily replaced and can be reversed once the life of the first edge has been reached.
It all depends on where they come from, some are made from high carbon steel, others are made from Hardox or manganese. Unless you know where Cat, John Deere or Volvo are or which manufacturer, it’s hard to know?
It is known as QT 100, which means hardened and tempered. It is also known as AR plate or wear plate. The supplier cuts them into large sheets according to our specifications. When I say specifications, I mean length, width and thickness. We use them on barrels to cut the edges. We also use a flame cut 45 on the leading edge to cut the edges. Before welding them in place, some preheating is required to prevent the weld cracking due to the hardness of the material.
This should help them a lot as the last time I worked on a loader bucket was after the ark was docked and the bucket was made of wood. I’m sure he had one he wanted to punch or something.
Loader bucket blades? Many new cutting edges have been made for the blades and I have seen many different grades of steel used. I’ve mainly used AR 400 or QT100. it all depends on what the service is.
I know that CAT now also uses the “Superabrasion” brand for aligning inserts and cutting edges. Superabrasion welding is bad, special process, still looks like crap ……
The maximum thickness of the cutting edge cross section of a loader bucket is limited to 35mm. Bolt-on tooth holders are rarely used on loader buckets with cutting edges thicker than 35 mm. This recommended practice only applies to straight cutting edges defined as having parallel leading and trailing edges and therefore a constant cross-section. The selection is based on the minimum cross-sectional width required to accommodate the bolt-on tooth adaptor. Note – for some heavy duty applications, larger blunt tips, larger miter angles and larger bolt hole cross sections may be required.
I used to haul the steel on a flat plate, it was called AR500 and was work hardened. Mark it out. Cut it and it was done, no re-cutting or retesting of these things. These materials are also used to make grader cutting edges and bucket teeth for excavators and track hoes.
Difficult and expensive to use, but performs well in a wear environment. The ability to hit the cutting edge directly with the shank without losing edge or deformation. Just be 100% sure where the bolt holes and countersunk holes are located so they align after welding, cutting and sharpening the edges. Good luck, hope this helps.
