Bucyrus International, Inc. 59HR ELECTRIC BLAST HOLE DRILL
PRECAUTIONS BEFORE AND DURING MAINTENANCE WORK The operator must be sure the equipment is in a safe position before repairs or adjustments are made. The machine should not be endangered by falling rock or a yielding support surface. Before beginning repair or adjustment, the operator shall: • • • •
Secure the rotary drive unit and tool string. Set all brakes. De-energize and tag control functions. Do whatever else is necessary to prevent accidental movement of the machine.
DANGER:
ALL PERSONNEL MUST BE CLEAR OF ELECTRICAL, MECHANICAL AND HYDRAULIC COMPONENT HAZARDS WHILE THE MACHINE IS OPERATING, OR WHILE USING THE CONTROLS DURING A REPAIR ACTIVITY.
Prior to beginning any work, maintenance personnel must notify the operator about the nature and location of the job. If work is to be done on or near moving parts, the engine must be shut off, the engine key switch in the “OFF” position with the key removed, and the controls should be tagged. The machine should only be returned to service when the maintenance personnel have completed all maintenance and have notified the appropriate personnel. Approved protection equipment such as hard hats, gloves and safety glasses should always be worn around the machine. When the engine is running, hearing protection should be worn. While performing maintenance, the awkward positions encountered often increase injuries due to handling heavy parts. As a precautionary measure, use mechanical lifting and handling equipment whenever possible. The mining foreman can facilitate safer and easier maintenance work by providing blocking materials, ladders and scaffolding. Service crews should have a fundamental knowledge of lifting practices so their knees and legs are used rather than their backs. DANGER:
Many of the components of the 59HR drill are heavy, bulky items. EXTREME CAUTION SHOULD BE USED WHEN LIFTING. Personnel should be certain of the weights of components before attempting to lift them, either manually or with some lifting device. FOLLOW ALL APPLICABLE SAFETY RULES WHEN USING CRANES OR OTHER LIFTING EQUIPMENT. BE SURE OF THE LOAD, LIFTING HEIGHT AND RADIUS, AND CAPACITY OF THE LIFTING DEVICE BEFORE LIFTING. Failure to follow all applicable safety rules when lifting can cause serious injury or death.
CAUTION:
USE EXTREME CAUTION WHEN STRIKING METAL PARTS WITH A SLEDGEHAMMER AS CHIPS MAY FLY OFF WITH GREAT FORCE AND POSSIBLY CAUSE SERIOUS INJURY. WEAR ADEQUATE PROTECTIVE CLOTHING INCLUDING A FACE SHIELD. Alternate methods of removal might involve using a ductile metal hammer or a hydraulic jack with suitable fixtures.
