Fixed position excavators like front shovels are ideal for hard digging applications at or above ground level.
The selection of excavating equipment depends on various factors including machine specifications, project requirements, and cost-effectiveness.
Productivity is influenced by the class of material, height of cut, and operator skill, all of which must be considered for efficient excavation.
A type of excavator designed for digging above ground level, utilizing a bucket that moves in an upward direction.
An excavator whose bucket moves in a downward direction, suitable for digging below ground level.
The sequence of operations in which the bucket is loaded, raised, swung to a dumping position, and returned for another load.
The height at which the excavator can achieve maximum productivity without needing to re-dig or experience spillage.
An important economic parameter associated with excavation work that reflects the efficiency and cost-effectiveness of the selected excavating machinery.
