Ensuring Safety: A Guide to Lift Planning for Success
In the world of rigging, meticulous planning is paramount. Let's dive into the essential process of lift planning, a cornerstone of safe and efficient lifting operations.
Why Lift Planning?
Whether you're tackling a routine or complex lift, planning is crucial for:
- Safety First: A well-defined plan minimizes risks and promotes a safe work environment. For critical lifts, a comprehensive plan is mandatory.
- Success from the Start: Planning ensures all aspects of the lift are considered, leading to a smooth and successful operation.
Who Creates the Lift Plan?
OSHA regulations require a qualified person to create the lift plan. This individual possesses a recognized degree, certificate, or extensive experience in hoisting and rigging operations.
What's in a Lift Plan?
A lift plan is a written document outlining the resources and procedures necessary for a safe and efficient lift. Key components include:
- Load Details: Exact size, weight, and center of gravity of the load (including rigging components) are documented.
- Crane Capacity: The crane's load chart and maximum load limits are specified.
- Lift Geometry: The crane's position, boom length and angle, and load radius are all defined throughout the lift's range of motion.
- The Lift Team: The plan identifies each team member and their qualifications (Lift Supervisor, Crane Operator, Signalperson, Rigger).
- Rigging Plan: This details the required hoisting hardware, designated pick points, and any special procedures.
- Ground Conditions: An evaluation of the crane's base (ground or outriggers) is conducted, including any necessary mats to ensure sufficient support.
- Water-Based Lifts: For these lifts, the characteristics and stability of barges, platforms, or other foundations are assessed.
- Weather Considerations: The plan outlines weather conditions that could halt the lifting operation.
Plan Review: A Collaborative Effort
Before the lift commences, a thorough review of the plan is crucial. This includes the plan's author, lift supervisor, crane operator, and all rigging personnel.
The Future of Lift Planning:
The American Society of Mechanical Engineers (ASME) is developing a standard (ASME P30) focusing on planning for various lifting scenarios (repetitive, standard, and critical). This standard will provide examples of situations requiring critical lift plans and identify those involved in the planning process.
By understanding the importance of lift planning and its key components, rigging professionals can ensure the safety and success of every lifting operation.
