Matching the bucket teeth on your excavator, loader or backhoe to the job reduces wear and tear on the bucket teeth and bucket. And it also allows your equipment to work at the maximum possible capacity.
Many times, the teeth in a new bucket are not right for your particular job. To make the best dental choice, consider the type of product you intend to relocate and the work your equipment will be doing.
The size and form of an excavator bucket tooth affects its efficiency. Forms include larger teeth that taper to a blunt point and narrower teeth that have a sharper element. Each shape changes the intake ratio of the teeth, or the percentage of dirt, rocks or other material that comes in contact with the entire tooth. Larger bucket teeth can place more surface than the product, facilitating basic loading and excavation applications. Teeth with a larger wear surface area typically last longer.
However, larger surfaces do not result in the ability to pass through compressed, frozen or rocky products. Trenching and excavation require tapered bucket teeth with pointed tips. Less hydraulic pressure and air intake is required to squeeze the bucket through the product due to the sharp teeth piercing the product.
The flared, universal bucket teeth can withstand moderate impact and unpleasant problems while leaving the smooth floor needed for trenching. Short bucket teeth are required for jobs that include high performance and prying out to work with rock.
Tough materials extend tooth life
The tougher the tooth product, the higher the resistance to wear, abrasion and impact, and the longer the wear life.
Unique diffusion and home heating techniques combined with specific product types such as cast isothermal hardened ductile iron (ADI) can produce stronger but lighter teeth. Backhoes, excavators and loaders use ADI teeth to produce moderate impact on high-impact tasks.
Wear-resistant teeth made of pliable iron can withstand the highly aggressive conditions caused by handling sand, gravel and rock. While more extensive recommendations offer additional penetration with crowded products, additional wear surfaces and ductile iron combine to extend tooth life.
Backhoes, excavators and graders can also use the standard teeth produced. Inconel-molybdenum alloy steel self-sharpening teeth offer an affordable solution for basic applications.
Depending on the application, manufactured high-strength cured bucket teeth are also available for loaders, scrapers, excavators and backhoes. Built-up teeth made of carbon, chrome, nickel and molybdenum steels are designed to resist wear and impact and offer higher flexibility and higher tensile strength than standard pliable iron teeth.
Impregnated teeth
Penetrating softer, thicker products (such as clay) requires bucket teeth with chisel edge points and facility ribs for additional support.
Penetrating harder products, such as sedimentary rock, concrete gravel and incorrect rock, requires single-tooth bucket teeth with sharp triangular points.
Some tasks require hard, hard-to-penetrate materials that often require fracturing. double-pick bucket teeth stay sharp and provide optimal penetration while being used primarily as edge teeth.
If in doubt about using the best teeth, consult an expert, such as a United Rentals representative, for advice. The performance gains and wear associated with using the most optimal teeth are worth investigating.
