The Type Es 3750 was built in almost exactly the same time as the F60s during 1978 in East Germany. [1] Each F60 were to be expected to be accompanied by two Type Es 3750 to assist the machine in transferring overburden and lignite coal. One Type Es 3750 is purposed to excavate the topside whilst another is used to excavate the depths. [2]

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 ...
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 ...
Subsets of the excavator bucket are: the ditching bucket, trenching bucket, A ditching bucket is a wider bucket with no teeth, 5–6 feet (1.52–1.83 m) used for excavating larger excavations and grading stone. A trenching excavator bucket is normally 6 to 24 in (152 to 610 mm) wide and with protruding teeth.
A dragline bucket system consists of a large bucket which is suspended from a large truss-like boom (or mast) with wire ropes. The bucket is maneuvered by means of a number of ropes and chains. The hoist rope, powered by large diesel or electric motors, supports the bucket and hoist-coupler assembly from the boom. The dragrope is used to draw ...

The clamshell bucket on the left hand side of the photograph on this page at Cardiff is a self-dumping chain grab. Generally, grabs have an open top to the shell body. Grabs handling light-weight powders which may be blown from the grab are sometimes fitted with covers which may be fixed or pivoted at the lower arm connection.
Products, services, and subsidiaries have been offered from International Business Machines (IBM) Corporation and its predecessor corporations since the 1890s.
