Equipment Checks
Prior to placing the unit in operation each day/shift, do a
complete walk-around visual inspection and look for
structural damage, loose components, leaks, or other
conditions that requires immediate correction for safe
operation. The following checklist of items are suggested to
ensure the crane is prepared for performing work operations.
Check:
• For any unusual conditions such as pools of hydraulic
fluid or lubricating oil under the chassis, any outrigger
which may have crept down or up and any signs of
damage or improper maintenance.
• The tires are inflated to the proper pressure.
• The level of the hydraulic reservoir oil.
• The operation of the “E-stop” and horn circuits.
• For missing and loose bolts.
• For damaged structural members and welds.
• All rope guides and rope keepers.
• All sheaves for free turning.
• The hoist rope for kinks, broken strands or other
damage in accordance with instructions under the
section Hoist Rope Inspection And Maintenance, page
