Making sure that every aspect of a crane is crucial before operation. To prevent damage to the machinery itself, people within the construction area, or machine failure that results in damaging other equipment on site, performing a safety check is necessary. From checking for crane stability pads to ensuring indicator lights are working and operation mechanisms are functioning, here are some of the things you need to check for:
Perform A Walk Around
One of the most overlooked aspects of inspection is a thorough walk around. To make sure the crane will bear load without sinking into the ground due to no crane outrigger pads and prevent many other issues, here are some of the things you need to check:
Is the foundation suitable for holding the crane load without outrigger pads?
Are all items on or near the crane secured?
Have the handrails and walkways been cleared and secured?
Are all hydraulic systems intact and operational?
Has housekeeping such as removing concrete or rebar been done?
Are all of the couplers and connection rods secured?
Remember, even if you are on solid ground such as asphalt, you may still need crane stability pads if the asphalt was poured over a hollow area where pipes are.
Inspect The Operator Cab
In addition to performing a walk around, you will need to inspect the operator cab to ensure the operator will have no problems while the crane is in use. Things to look for include:
Has general operator cab housecleaning been done?
Are all warning tags visible?
Are the cab doors secure?
Is the fire extinguisher in place?
Is visibility acceptable or does window cleaning need to happen?
Are all indicator lights functioning?
Is the alarm system working?
One of the most important aspects of your inspection is going to be the operation inspection. In many cases if you find issues with any of the operation parts during an inspection you will need to suspend work and notify a supervisor. Operation inspections include checks for:
Travel Limit Relays
Hooks (Main and Auxiliary)
Bridge Controls and Brakes
Main and Auxiliary Upper and Lower Limits
Power Supply Replay
Work Area Checks
Manual Reset Checks
In addition to operation checks, you will need to also perform machinery inspection. Machinery that you need to inspect are:
Check Hooks for Deformities or Cracks
Are all motors operational?
Bridge Conductors and Collectors
Are there any exposed electrical components?
Check the Festoon System
Are batteries working properly?
Are all covers secured?
If you notice any issue with the holding brake, wire rope, sheaves, or hook it is recommended that you contact a supervisor and end any operations for the crane.
