Abstract: A drawworks for a rig is disclosed. This drawworks may be used by any appropriate type of rig, such as a drilling rig or a service/workover rig. The drawworks includes at least one drum (e.g., a main drum, a sand drum), and each such drum may incorporate a number of desirable features. For instance, the drum may include a lubricant flowpath with at least one annular section that reduces the potential for clogging. This drum may also include a drive hub that is detachably interconnected with one or more drive sprockets so as to facilitate repair/replacement. Finally, this drum may include one or more structures for reducing the potential that certain lubricant will reach the clutch, where this lubricant is propelled from one or more rotating drive sprockets and/or the associated chain.
