It differs from the ISO control pattern only in that SAE controls exchange the hands that control the boom and the stick. This control pattern is standardized in J1814 [ dubious – discuss ] . In the SAE control pattern, the left hand joystick controls Swing (left & right) and the Main Boom (up &down) , and the right hand joystick controls the ...
A unique design choice for the Type Es 3750 is the presence of two excavator's control cockpit, each spraying outwards on the left and right side of the machine. Given that it predominantly moves side-to-side with the F60, this is to be expected. [2] Likewise, it also possess a small complement of men of around 2–5. [2]
The largest form ever of an excavator, the dragline excavator, eliminated the dipper in favor of a line and winch. On the end of the stick is usually a bucket. A wide, large capacity (mud) bucket with a straight cutting edge is used for cleanup and levelling or where the material to be dug is soft, and teeth are not required.
Bucket wheel excavators and bucket chain excavators take jobs that were previously accomplished by rope shovels and draglines. They have been replaced in most applications by hydraulic excavators , but still remain in use for very large-scale operations, where they can be used for the transfer of loose materials or the excavation of soft to ...
a bucket, usually with a toothed edge, to dig into the earth; a "dipper" or "dipper stick" connecting the bucket to the boom; a "boom" mounted on the rotating platform, supporting the dipper and its control wires; a boiler; a water tank and coal bunker; steam engines and winches; operator's controls; a platform on which everything is mounted
A bucket chain excavator works similarly to a bucket wheel excavator, using a series of buckets to dig into the material before dumping it in the bucket chute and depositing it through a discharge boom. The primary difference is that the buckets are mounted on a flexible chain similarly to a chainsaw blade rather than on a rigid wheel. BCEs are ...

Power shovels normally consist of a revolving deck with a power plant, drive and control mechanisms, usually a counterweight, and a front attachment, such as a crane ("boom") which supports a handle ("dipper" or "dipper stick") with a digger ("bucket") at the end. The term "dipper" is also sometimes used to refer to the handle and digger combined.
