How to Choose the Right Excavator Bucket

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.

How to Calculate Excavator Bucket Capacity

Time a loading operation with a stopwatch. Start timing when the excavator bucket begins to "dig in" and stop timing when the bucket again begins to dig in. Divide 60 by the cycle time to learn the number of cycles per hour. If the cycle time is .5 minute, 60 / 0.5.

Excavator

 · Performance of excavator can be measured from the production cycle. Production cycle is the time that an excavator took to load the bucket from source, swing, dump, return back and then dig again. Therefore, faster the operation speed, the faster will be the one complete cycle and hence production cycle will increase.
