The Lifting Plan


• The Lifting Plan is a set of plans developed for use in

any crane lifting operation

• Lifting Supervisor will take hold of the lifting plan but the

lifting team should be familiar with the Lifting Plan and

ensure that the lifting operation is carried out according

to plan

• Any party who has the expertise and relevant knowledge

can create the lifting plan. After which, both the occupier

and the contractor have to agree upon the document


Developing the Lifting Plan


Key Factors to be Considered


1. Site Surrounding Conditions


• Environmental factors• Environmental factors• Location/Site Hazards• Lighting Conditions• Demarcation


Generic Environmental Hazards to be Considered:

• Indoors/Outdoors• Indoors/Outdoors

• Suitability of lighting (Day/Night)

• Noise

• Weather conditions: Rain, Haze, Bright Sunlight,

Strong Winds, Thunderstorms, Lightning

• Ground stability


Location

• Mass Rapid Transit system (MRT)• Public areas• Public areas• Build-up areas• Near water bodies• Overhead Restriction• Underground Services


• Underground Services

Site Hazards

• Access / Egress around lifting equipment clearly identified

• Working at Heights• Ground Stability and level• Restricted area to establish outrigger supports

(mobile cranes)• Blind spots during maneuvering of load and lifting


• Blind spots during maneuvering of load and lifting equipment.

Demarcation / Barrication

• Area of maneuverability; when using equipment.

• Area of maneuverability; when using equipment.

• Lifting Zone• Working within a confined space or tunnel• Other activities on the work site


2. LOAD


• Description of Load to be Lifted• Description of Load to be Lifted

• Details of Load to be Lifted


Load Crucial Information

No load must be lifted without the following crucial information:

• the load weight • the load weight

• the overall dimensions (length, width and depth).

• indication of the position of centre of gravity.

• the lifting/slinging points

• the pickup radius

• the final location radius

• the height to which the load has to be lifted.


• the height to which the load has to be lifted.

• the overall weight (load + all lifting accessories)

3. Risk Assessments


4. Lifting Equipment/ Gears


Using the previously gathered information in conjunction with

Lifting Equipments / Gear

Using the previously gathered information in conjunction with

crane manufactures duty charts it will allow the selection of a

crane that is suitable with sufficient capacity to safely execute

the lifting operation.


Details of the Lifting Equipment

Details of the preferred Lifting equipment(s) to be used must be recorded within the Method Statement and must include:

• Make and model;

• Capacity

• Validation of Certification

• Maximum ground bearing capacity

• Configuration

• Weight of the crane

Details of the Lifting Gears

• Capacity


• Capacity

• Validation of Certification

• Types (Shackles, Wire Rope, Belt etc)

Lifting Supervisor

• Nominated by the appointed person and appointed in writingand appointed in writing

• In charge of actively supervising the lifting operation

• Responsible for planning lifting

operations in accordance to the Lifting Plan


Lifting Plan

Roles and Responsibilities:

• Ensure that only registered personnel participate in any lifting operation

• Ensure lift operation is conducted in a safe manner

• Brief all personnel on the safe lifting procedures

• If any unsatisfactory incidents are reported to him, take measures to rectify them

• Monitor equipment maintenance and inspection

• Check on the set up of equipment and ensure that equipment are

properly set up before lifting operation commences


Roles and Responsibilities:

• To be responsible for the lifting job carried out by him

• Do daily crane inspection prior to the lifting operation and to report

any findings

Crane Operator

any findings

• Record daily operation log

• Ensure cranes are properly set up before lifting operation commences

• To adhere to instructions given by Lifting Supervisor

• Check and ensure that the load is correctly secured, rigged and sling

before lifting

• Check the clearance of the path to be taken by the load and any part


• Check the clearance of the path to be taken by the load and any part of the crane

• Report any accident/incident/dangerous occurrence and unsafe act/conditions

Rigger & SignalmanRoles and Responsibilities:

• Ensure lifting operation is not undertaken without suitable and sufficient appropriate risk assessment and that lifting

equipment is not used without prior training and appropriate equipment is not used without prior training and appropriate supervision

• Carry out pre-use checks of lifting equipment, to ensure

equipment is in good working condition

• Report any damages to the equipment or any accident/incident/dangerous occurrence and unsafe

act/conditions to the Lifting Supervisor as soon as is reasonably practicable


reasonably practicable

• Ensure proper set up of equipment before lifting operation

commences

7. Classifications of Lift


1. Routine Lift

Lifting operations may be executed under a basic lift plan. These plans must clearly define the lift plan. These plans must clearly define the limitations on the loads, lifting methods and

areas of operation. A Risk Assessment will be required in each case, and authorized prior to commencement. A Non-Routine may also be

completed using similar documents but will require greater detail. Prior to any lifting operation commencing, a review of the lift plan


will be conducted.

A Routine Lift is a lift which conforms to the following factors:

• Within the normal operating parameters of the crane

• Lifting over non-sensitive areas• Suitable environmental conditions• Load has known and evaluated weight, shape and centre of gravity

• Standard rigging arrangements• Routine repetitive lifting operations using the same equipment• Single function or series of functions repeated manually or automatically

• Order of function repeated• Same equipment• Same competent Crane Operators

• Load under 75% of rated load of the load chart• Centre of gravity below the lifting hook Use of a certified lifting point • Single lifting machine


• Single lifting machine

• Unlikely to be affected by changing environmental conditions• Standard rigging arrangements• Suitable lay-down area available

2. Non9Routine Lift

All remaining categories which fall under Non-Routine will require a more detailed Lifting Plan Routine will require a more detailed Lifting Plan containing all of the elements as described above.

The plan will have to be approved by a Responsible Person prior to commencement of any Lifting Operation and any deviation

requirement identified from the plan, must also get the approval of the Responsible Person prior to commencement of the lifting operation.


commencement of the lifting operation.

Conforms to the following factors:

• Use of two or more Lifting Appliances, Tandem Lift

• With sensitive, difficult or restricted areas

• Lifts from one offshore vessel to another• Lifts from one offshore vessel to another

• Continuation of a lifting operation with different people

• Lifting of machinery without lifting points

• In environmental conditions likely to affect equipment performance

• Load with unknown/difficult to estimate weight and/or centre of

gravity

• Non-standard rigging arrangements


• Load lowered into or lifted from a confined space

• Weight of load in excess of 75% rated load of the load chart

Conclusion• A proper planned operation reduces the risks of crane-related

accidents and minimizes costs• Make sure all lifting operations are planned according to the lifting • Make sure all lifting operations are planned according to the lifting

plan and make sure lifting operations do not deviate from lifting plan• Stop all lift operations if there is deviation• Safety is the most important aspect
