. According to

, they boast that the Type Es 3750 is the largest bucket chain excavators in the world. Type Es 3750s are notable for being always used in conjunction with the Overburden Conveyor Bridge F60, another absurdly large land vehicle.

Specifications

The Type Es 3750 are incredibly immense digging vessels, the largest of its kind according to

. Each Type Es 3750 has the total length of , a height of and a weight of . The cutting height of the BCE's chain boom is to , whilst its cutting depth is to . In total, the chain boom is capable of excavating a maximum capacity of 14,500 m³/h. The buckets itself is reinforced by 5 to 10 mm steel plates to prevent deformation and wear-and-tear. 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. Likewise, it also possess a small complement of men of around 2–5. Another unique feature is that the Type Es 3750 runs on rails. Since it is largely grouped closely with the F60, the Type Es 3750 share the same gauge as the F60 - {{convert, 1,435, mm, inch, 0, abbr=on, order=flip. Likewise, the vehicles share their power source with the F60 and the nearby external coal power plant and therefore, moves the same speed as the F60.

Operations

The Type Es 3750 was built in almost exactly the same time as the F60s during 1978 in

. 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. Excavated materials would be transported on side conveyors towards the F60 for the materials to be properly redistributed. As there were originally five F60s, a total of 10 Type Es 3750 BCEs were built, but with the retirement of one of the F60s in Lichterfeld-Schacksdorf, only 8 remain in service.
