Bucket excavators/FE Loaders - Capabilities & timings

A bucket excavator or front end loader can be judged for performance by its bucket capacity, measured in cubic metres or yards, and by its cycle time (ie the average time taken to remove a quantity of sand or earth from the ground and place either to one side, or into a truck) measured in seconds. These calculators can be used for determining how long a particular machine will take to excavate or load a specified volume of material or, if a choice of machines is available, which might be the most economical or, whether more than one machine might be required if time is limited. All results will be ball-park in nature, because much will depend on performance characteristics of machines available and on conditions peculiar to the work site. However, such calculations are often useful and frequently overlooked during the planning/estimating stage of a project. also useful for "what iffing" exercises. Hypothetical examples are used.
