How to Choose the Right Bucket
Selecting the right excavator bucket for your task is critical to get the most out of your machine. Some important factors to consider when choosing a bucket include ground conditions at the job site, material type and machine compatibility.
For example, a digging bucket will excel in projects with loose soil where general excavation is a major goal, whereas a trenching bucket would be a wiser choice for precision work in tight spaces.
In addition to choosing a bucket that’s appropriate for your project requirements, be sure to choose a bucket that will be compatible with your excavator. Not every bucket is suitable for every excavator. The the size of your excavator will determine the largest bucket size you should use with it.
Mini excavators, for example, should not be used with 60” buckets designed for full-sized machines. To figure out the largest bucket you can use with your excavator, consult your machine’s operating manual which will provide the recommended bucket widths for your machine.
Bucket Maintenance
While excavator buckets are designed to withstand harsh conditions, they must be maintained properly in order to maximize their efficiency and longevity. Like other aspects of heavy equipment maintenance, the key to excavator bucket maintenance lies in establishing an effective preventative maintenance plan.
Here are some key aspects of bucket maintenance to include in your plan:
- Inspect your buckets before and after each shift.
- Clean the bucket after each use to remove dirt and debris.
- Store the bucket in a dry, covered area.
- Regularly grease pivot points and moving parts.
- Do not exceed the bucket’s lifting capacity.
- Train operators to use the bucket properly, avoiding aggressive techniques that could cause wear.
