3-60ton excavator heavy duty tilt bucket for all type excavators EX PC R SK volvo

Choosing an excavator for your job is only the first step in acquiring the tools you need. Whether they’re mini or large, excavators are incredibly versatile because of the available bucket and attachment options. Given the many types of backhoe and excavator buckets on the market, a lot of factors contribute to finding the right bucket for the job.
From understanding excavator bucket dimensions to learning about the different excavator bucket types, this guide will teach you how to choose the right excavator bucket for your needs.

Excavator Bucket Size Chart
Generally, a range of bucket sizes will work for the excavator you have. Mini excavator bucket sizes can range from specialty 6-inch buckets to 36-inch buckets. Keep in mind that some sizes only apply to grading buckets, and you shouldn’t use other types of buckets with those dimensions.
To see what size of bucket is possible for the weight of your excavator, use this excavator bucket size chart:
Up to 0.75-ton machine: Bucket widths of 6 inches to 24 inches, or 30-inch grading buckets.
1-ton to 1.9-ton machine: Bucket widths of 6 inches to 24 inches, or grading buckets 36 inches to 39 inches.
2-ton to 3.5-ton machine: Bucket widths of 9 inches to 30 inches, or 48-inch grading buckets.
4-ton machine: Bucket widths of 12 inches to 36 inches, or 60-inch grading buckets.
5-ton to 6-ton machine: Bucket widths of 12 inches to 36 inches, or 60-inch grading buckets.
7-ton to 8-ton machine: Bucket widths of 12 inches to 36 inches, or grading buckets from 60 inches to 72 inches.
10-ton to 15-ton machine: Bucket widths of 18 inches to 48 inches, or 72-inch grading buckets.
19-ton to 25-ton machine: Bucket widths of 18 inches to 60 inches, or 84-inch grading buckets.

How is Excavator Bucket Capacity Calculated?
Each job’s bucket capacity depends on the size of your bucket and the material you are handling. Bucket capacity combines the material fill factor and density, the hourly production requirement, and cycle time. You can calculate your bucket’s capacity for a particular project in five steps:
Find the material weight, expressed in pounds or tons per cubic yard. Refer to the Fill Factor Data Sheet provided by the bucket manufacturer to find the fill factor for that particular material. This figure, expressed as a decimal or percentage, specifies how full the bucket can be with this type of substance.
Find the cycle time by timing a loading operation with a stopwatch. Start the timer when the bucket begins digging and stop when the bucket starts to dig a second time. Take 60 divided by the cycle time in minutes to determine cycles per hour.
Take the hourly production requirement — set by the project manager — and divide it by the cycles per hour. This calculation gives you the amount in tons moved per pass, known as the per cycle payload.
Take the per cycle payload divided by the material density to arrive at the nominal bucket capacity.
To calculate the heaped capacity of your bucket, you need to factor in the volume of the bucket and the weight of the material on top when it is not leveled off. First, measure the volume of the inside of the bucket, then add the material’s angle of repose. The ratio to work with is 2:1 for wheel loader buckets and 1:1 for hydraulic excavator buckets.
The struck capacity is the volume of your bucket after being leveled across the top of the bucket. Calculate the struck capacity by measuring the volume of the bucket by multiplying the length, width, and height.
Divide the nominal bucket capacity by the fill factor. This number tells you exactly how many cubic yards of material you will be able to lift with each cycle.

What is a Heavy-Duty Bucket?
A heavy-duty or severe-duty bucket is usually made from high-strength, abrasion-resistant steel. Because of their superior durability, these attachments are often used in rock quarries to load trucks with high-density material in fewer passes.
excavator buckets come in general-, heavy-, severe-, and extreme-duty varieties. They provide enhanced digging for heavy or abrasive materials, such as:
Blasted rock
Hard-packed clay
Stone
Sharp rock
Ripped basalt
Gravel
High-silica sand
Shot granite
Shale
Severe- and extreme-duty buckets can handle even heavier materials, including:
Limestone
Sandstone
Broken slag
Basalt

Standard Bucket: Apply to light operation task, such as digging and loading hard soil or stones nixed with the soft soil.
Heavy Duty Bucket: Suitable for digging hard soil, soil mixed with soft stone, loading gravel, broken stone and so on
Rock Bucket: Suitable for digging earth with hard rock, sub-hard stone and weathered stone, it also can do heavy work,such as digging and loading solid rock, blasted ore
Skeleton Bucket: Apply to clean the watercourse. It can be used for underwater work.
Quick Change Bucket: Apply to the construction site which should be worked flexible.
