MOBILE CRANE INSPECTION CHECKLIST
BENEFITS
Many workplaces use hoisting apparatus, such as mobile cranes, to move materials. Such equipment can protect workers from injuries they could suffer if they moved the materials by hand. But if the cranes aren’t properly maintained, they can pose a safety hazard to workers. That’s why the OHS laws usually require employers to make sure that such equipment is regularly inspected to ensure that it’s safe to use.
HOW TO USE THE TOOL
Adapt this checklist to meet the requirements of the crane’s manufacturer/supplier and your jurisdiction’s OHS law. Useit to document inspections of mobile cranes. It should be completed by the crane operator and signed off on by a supervisor. Keep the completed checklists so you’ll be able to demonstrate that you regularly inspected your crane in case there’s ever a safety incident involving it.

YES / NO / COMMENTSCrane operator certification
Crane operator is properly certified
Employer can confirm operator is qualified and trained to operate crane
Operator certification is current and correct for crane size and type
Certified trainee has indirect and direct supervision
Annual crane inspection
Current annual inspection documents are available for review, confirming that an engineer has inspected and certified all critical components (structural, mechanical, controls) as safe for use
A crane boom used with a vibratory hammer for driving piles is inspected at least once every 3 months
A crane boom used with a vibratory pile extractor or a drop hammer, or used for
dynamic compaction is inspected at least once a month
Stability testing
Certified stability test document is available for review. Document states unit (crane and carrier) has been tested to ANSI J765, Crane Load Stability Test Code. Document confirms crane is safe to operate in all positions (360°) using manufacturer’s supplied load chart or that crane has reduced capacity in some positions and certified Custom Load Chart is provided to confirm actual allowable crane loads
Manufacturer’s manual
Manufacturer’s manual is in machine or at the worksite for review and reference
Log book
Pre-shift inspection is documented in maintenance log book. Inspection includes machine components referenced in manufacturer’s manual or standard
Log book has entries for all inspections, testing, modification, repair and maintenance
Outriggers
Crane outriggers are extended and set as per manufacturer’s load chart or custom load chart
Crane outrigger beams are marked to indicate correct extension is achieved
Crane outrigger float pads are set on appropriate cribbing for soil or base (minimum 3:1 cribbing under float pad)
Crane outriggers or track frames are a minimum 1:1 distance away from slope or excavation depth.
Crane support surface is adequate or certified to support machine and load safely
Crane is set up with turntable level (usually 0° to 1° — refer to operator’s manual)
Crane on floating support (barge or derrick) has certified marine load chart and listometer device
Site-specific circumstances
Critical lift procedure is in place for tandem (two-crane) lift, crane-supported work platform, lift over and between high-voltage power lines, lifting a submerged load, load centre of gravity changing, or 90% of crane capacity @ 50% crane boom length
People on-site who aren’t involved in crane operations are aware of lift hazards and are safe
Is crane load or machine slewing a hazard? Will loads be passed over people?
Operator has full control of crane and isn’t engaged in other duties
Operator knows weight of load being lifted
Traffic control is in place, if required
High-voltage power lines: minimum limits of approach procedure is developed, reviewed and followed
Crane and equipment overlapping procedure is in place for crane-crane, crane-tower
crane or crane-pump truck
Qualified signal person has clear view of lift areas that operator can’t see
Safety devices
Lift crane (not duty-cycle crane) with capacity of 11 tonnes or more has load cell or manufactured system that doesn’t allow crane to lift beyond rated capacity
Lift crane (not duty-cycle crane) has anti-two-blocking device, which includes articulating boom cranes fitted with a winch (as per CSA and ASME Standards)
Telescopic boom or lattice boom crane has boom angle indicator (mechanical or electric)
Crane has a horn (audible warning device)
Fire extinguisher is in crane cab
Maintenance, inspection and repair
Crane mechanical deficiencies are noted in log book. Crane inspected frequently enough to ensure components are capable of carrying out original design functions (as referenced in operator’s manual and standard)
Crane maintenance and repair is done by or under direct supervision of qualified person
Crane structural and load-bearing repairs are certified
Crane hoist lines are inspected for broken wires, crushing and correct drum spooling
Crane outrigger float pads are secured to outrigger jacks
Crane controls are clearly marked for their function
Load information / DESCRIPTIONS AND WEIGHTS
Load description (name, size, lengths, shape)
Load weight (from manufacturer, design drawing, trucking company scale)
Crane block and ball weight (from crane load chart or manufacturer’s manual)
Load rigging weight (from rigging supplier or scale)
Gross load weight (load weight + block/ball + rigging)
Crane information
Crane boom length and configuration: counterweight installed per configuration
Load placement distance (crane boom radius from centre pin)
Crane gross capacity (from load chart @ radius @ boom length/configuration)
Crane component deductions (weight of crane jib, load line, rooster sheave from load chart)
Crane net capacity (crane gross capacity — crane component deductions)
Percentage of crane capacity (gross load weight ÷ crane net cap x 100)
