Study Notes

Crane Operation Safety

Crane operator must maintain direct eye contact with the signalman.
Mobile phone functions are strictly prohibited while operating or driving cranes.

Rigger Certification

All riggers must be certified by ITD as Rigger-III, Rigger-II, or Rigger-I.
Certifications are valid for a maximum of two years.
Rigger-III can rig loads up to 10 tons, except for loads requiring a Rigger-I or Rigger-II.
Rigger-II can rig loads up to 40 tons, originate Critical Lift Plans, and rig/supervise crane-suspended personnel platform operations.
Rigger-I can rig all loads and approve Critical Lift Plans for critical lifts.
Riggers may only rig loads exceeding their certification level if supervised by a Rigger of a higher certification level or a rigging competent person.
Loads in approved Critical Lift Plans shall be rigged by a rigger certified for that load category, but all loads of 40 tons or greater require a Rigger-I or a rigging competent person to supervise the lift.

Rigging Competent Person

A rigging competent person should only be used as a last resort.
This designation is only for special cases when a Saudi Aramco certified Rigger-I is unavailable.
The User department manager designates the rigging competent person in writing and assumes full responsibility for their designation.
The rigging competent person is only designated for the Rigger-I category.

Definitions

Crane: A rotating superstructure with a power plant, operating machinery, and boom mounted on a base equipped with crawler treads or axles and rubber-tired wheels for travel.
Crane Lift - Critical: Any crane lift that requires a Critical Lift Plan.
Crane Lift - Standard (Ordinary): Any crane lift not classified as a critical lift.
Crane Operator: A person certified by Saudi Aramco to operate a specific model and capacity of crane.
Critical Lift Plan: A document (SA 9644) that identifies a specific load and operating restrictions.
Operational Aid: A component that provides information to facilitate crane operation or controls crane functions without the operator's action.
Originator: The person completing the Critical Lift Plan form, typically a Rigger-I, Rigger-II, or rigging competent person.
Rated Capacity [Load] Limiter (RCL): A device that prevents crane movement in overload conditions, monitoring radius, load weight, and load rating.
Rigger: A person certified by Saudi Aramco to prepare a load for lifting.

Critical Lift Requirements

A Critical Lift Plan must be on site prior to the lift.
Rigger II and Rigger III can perform and coordinate lifts within their certification limits after the Rigger I approves the Critical Lift Plan.
The following critical jobs are restricted to Rigger I: tandem lifts, lifts exceeding 85% of the crane's rated load capacity, working near energized power lines, and rubber pick and carry.
Special Critical Crane Lifts (tailing, tandem, turning lifts, crane suspended personnel platforms):
- These lifts require an approved Critical Lift Plan, a Rigger-I/rigging competent person in charge of coordination, and specific de-rating requirements.

Railway Lines

Cranes working within 10 meters of a railway line require a copy of the railway train schedule as an attachment to the Critical Lift Plan.
