摘要： A field adjustable block (10) for use with a bridge crane (12) having a rotating cylindrical drum (14) for rope. The block (10) includes a cylindrical center pin (30) having a key way recess (40) parallel to an axis of the center pin (30). An inner side plate (42) has an opening (44) therethrough and an extending key (46) receivable in the key way recess (40) to prevent rotation of the inner side plate (42). Multiple sheaves (50) are receivable over the center pin (30). At least one toroidal spacer (54) is receivable over the center pin (30). A lock washer (58) has an inwardly extending key (60) receivable in the key way recess (40) of the center pin (30) and has a plurality of radially extending tabs (62). A nut (64) has at least one notch (66) to receive one of the extending tabs (62) therein. An outer side plate (70) is removably attached to the inner side plate (42) by fasteners (72).

摘要： A retaining keeper assembly for a hoisting device. A shank has a plurality of circumferential grooves perpendicular to an axis of the shank. A thrust bearing surrounds the shank and is supported by the hoisting device. A split retaining collar having a plurality of interior circular protrusions mates with the circumferential grooves in the shank to prevent axial movement of the shank. A cylindrical retaining keeper ring having an open top and an open bottom encloses the assembled retaining collar, the keeper ring having an inner diameter slightly larger than an outer diameter of the retaining collar. A pair of retaining rings surround the split retaining collar above and below the keeper ring to trap the keeper ring in place.
