  • Method of refurbishing a bucket wheel reclaimer
    Patent number: 11498768
    Abstract: A method 10 of refurbishing a bucket wheel reclaimer (BWR) 41 having structural frame 68, a chute 66 supported by the structural frame 68, a yard conveyor 42 for receiving material from the chute 66 and an impact table 64 supported by the structural frame 68 below a portion of an upper run 44 of the yard conveyor 42. The method includes a step 12 of decoupling a current impact table 64 from the BWR structural frame 68. The impact table 64 is lowered at step 26 from the structural frame 68. Thereafter at step 14 the current impact table is moved laterally away from and to one side of the yard conveyor. At steps 16 and 18 a fresh impact table is moved laterally to a location beneath the upper run 44 of the yard conveyor and coupled to the BWR 41.

  • A ROTABLE BUCKET WHEEL ASSEMBLY AND A METHOD FOR REFURBISHING AN ASSOCIATED BUCKET WHEEL RECLAIMER
    Publication number: 20210355650
    Abstract: A bucket wheel assembly (40) includes a structural frame (42) that in use forms a structural part of the boom of a bucket wheel reclaimer. The structural frame (42) supports a bucket wheel (44) having a plurality of attached buckets (46); a ring chute (48) and an associated discharge chute (50). The bucket wheel (44) is attached to the middle of shaft (51), which is supported by two bearings (52). The drive unit is attached to the shaft (51) to provide the rotation torque, and the drive unit is also attached to the structure (42). The structural frame (42) couples to a portion of the boom and transfers the assembly load to the boom when the reclaimer is in operation.
