Sub-section : Introduction, Aims & Objectives Page: 5 of 56

1 INTRODUCTION
Safe system of work is an integral part of any lifting operation, whether it is a simple, repetitive or
complex operation that is required to take place. Through the implementation of the rules
contained in this part, management responsibility is to provide a safe system of work.

2 AIMS AND OBJECTIVES

The aims and objectives of this Part is to familiarize employees who participate in lifting
operations with the various roles and responsibilities that will assist in ensuring safe lifting
operations.

The aims of this part are to:

ƒ Describe the planning process for lifts and crane operations;
ƒ Define the roles and responsibilities of the various personnel;
ƒ Provide guidance in order that lifting equipment may be used in a safe manner;
ƒ Suggest frequencies for inspection to satisfy ADCO requirements.

The objectives of this part are to:

ƒ Define what ADCO considers to be lifting equipment;
ƒ Describe how it shall be used and maintained;
ƒ Specify the roles and responsibilities of the various staff in planning and conducting lifts in a
variety of circumstances.

This is achieved through:

ƒ ensuring lifting appliances, hoists and lifting gear are certified and fit for purpose;
ƒ ensuring lifting operations are planned and controlled so that a safe system is provided and
maintained;
ƒ Ensuring all personnel involved in lifting operations are qualified to do so and have been
given sufficient training in safe lifting methods.

3 PLANNING

3.1 Control

A Crane Coordinator shall be appointed by the management to be in overall control of the lifting
operations. The Crane Coordinator must have had adequate training and experience and be
competent. The Crane Coordinator shall carry out the following duties:

ƒ Make a risk assessment of each lifting operation;

ƒ Plan each operation and select the most suitable lifting appliance, gear and equipment;
ƒ Consult co-ordinate and gain approval from the relevant departments prior to lifting
operations taking place;
ƒ Ensure that inspection and maintenance procedures are in effect for the selected plant and
equipment and up-to-date test and thorough examination certificates are available at the work
location;
ƒ Ensure that procedures exist for incident and defect reporting.

3.2 Written Plans

The Crane Coordinator shall provide a written plan for lifting operations which shall include a
risk assessment, details of the equipment to be used, together with safe working loads, the general
precautions to be taken, availability of telephones, first aid equipment, etc.

The written plan shall also provide details of the person who will be in charge of the operation,
together with details of other key personnel.

3.3 Weight of Load

The Crane Coordinator shall determine the weight and centre of gravity of the load to be lifted. In
the absence of this information from the supplier, the weight of the load shall be determined either
by weighbridge, load cell or accurate calculation.

The weight of the block and of any lifting gear to be used shall be included in the total weight to
be lifted.

Part : 19-Section 1 Date: 09/05

Sub-section : Planning Page: 7 of 56

3.4 Simple Operations

Simple operations do not require elaborate planning. A note of the weight to be lifted and the
maximum radius that must be used from the centre of rotation of the crane shall be sufficient.

Information on the height to or from which the load is to be handled and an explanation of the
slinging arrangements shall also be included in the planning of simple operations.

3.5 Repetitive Operations

Straightforward repetitive operations will require to be planned only once. The Lifting Supervisor
shall monitor the operations to ensure no changes occur that require a revision of the risk
assessment or method of work.

3.6 Complex Operations

More complex operations will require more detailed planning and preparation. The plan, risk
assessment and method statement shall be accompanied by drawings, sketches or photographs in
order to make completely clear to the personnel concerned, how the operation is to be handled and
the correct sequence in which the work is to progress.

3.7 Tandem/Multiple Operations

Multiple or tandem lifting operations, involving the use of more than one crane, require the
following:
¾ Detailed & careful planning (Crane Coordinator);
¾ Proper Risk Assessment;
¾ Accurate Assessment of the load on each crane;
¾ Similar crane capacities is preferable;
¾ Use one Banksman to signal both crane operators;
¾ Use suitable lifting accessories;
¾ If ASLI available on crane; each crane needs to lift 25% above estimated share of load;
¾ If ASLI not available on crane; each crane should lift 75% of total load.

(Note: Due to the complexity and stress involved in tandem/multiple lifting, this practice is not
recommended).

Sub-section : Planning Page: 8 of 56

3.8 Access

Access for both the lifting equipment and the load to be lifted is considered at the planning stage.

The following matters shall be included:

ƒ the suitability of public roads and site condition for the movement of large cranes and large
loads;
ƒ the widths of entrances to allow the passage of large loads without interrupting the movement
of other traffic;
ƒ sufficient space shall be available in which to erect mobile cranes for the work and space to
accommodate the maximum length of jib to be erected, together with sufficient space for
movement of the auxiliary crane;
ƒ arrangements for closing the area during the erection of the crane, the lifting operation and the
subsequent dismantling of the crane, so as to completely exclude all personnel, other than
those immediately connected with the operations.

3.9 Ground Conditions

The Crane Coordinator shall ensure that the ground conditions both in relation to access and the
load, which will be imposed during the erection and operation of the crane, are capable of
withstanding the pressure.

3.10 Effect of Wind Speed on Crane Operations

Any Crane working on site should have Wind Speed Indicator (Anemometer) in order to warn the
operator and/or cut-off crane operation if the wind exceeds the pre-determined speed as per
ADCO requirements 32 km/h (20mph), or the crane limitation due to manufacturer specifications.

3.11 Overhead Power Lines and Other Obstructions

At all stages during the progress of a lifting operation, from planning through to completion, the
Crane Coordinator shall ensure that precautions are in place to avoid overhead power lines and
other overhead obstructions. The overhead protection shall be placed at least 1½-jib lengths on
either side of the power line.

Arrangements to ensure clearance from obstructions shall include due allowance for the tendency
of crane jibs to "bob up and down", both during the lifting operation and when traveling.

Certifying Companies

Volume : 10 (HSE) Revision 2

Part : 19-Section 1 Date: 09/05

Sub-section : Planning Page: 9 of 56

As a general rule, a minimum clearance from overhead power lines of 6 meters is required to be
maintained at all times.

Flag Man should be appointed to warn the crane operator if accidentally exceeds the minimum
clearance.

When it is necessary for lifting appliances to pass under power lines, warning notices shall be
placed on both sides before and after the overhead line of the road or track and an overhead
barrier, supported on goal posts and provided with bunting shall be erected to ensure that jibs are
brought below the danger level before passing under the lines.

3.12 Proximity Hazards

Consideration should be given to the presence of proximity hazards such as overhead electric
lines or cables, nearby structures, other cranes, vehicles or public access including highways. The
danger to or from underground services, such as pipelines, electric cables should not be
overlooked. Precautions should be taken to ensure that the crane foundation is clear of any
underground services or where this is not possible, that the services are adequately protected
against damage.

At any place where a crane or its load passes an obstacle, the following points should be
observed;

a) Where practicable, the crane path should be clearly defined by marking to ensure it is kept
free from obstruction all the time, and a clearance of not less than (600 mm) should be
arranged between any part of the crane and any obstacle. Precautions must be taken to
avoid access to any trapping hazards.
b) Where goods are regularly stacked near a crane boundary, lines for the stacking goods
should be permanently marked on the ground.

4.1 Periodic Checks

Lifting Operation Supervisor and Crane Operator should ensure that the following crane
checks have been carried out.

4.1.1 Daily Checks:

At the beginning of the working day and before use, the following routine checks, as
appropriate for the type of crane, should be carried out:

• Checks as required by the manufacturer’s handbook;

• Check that all ropes are free from defects (e.g. broken wires, reduced
diameter, …etc.) and are correctly positioned on their sheaves and drums have
not been displaced and check for proper spooling on drum;

• Visually check that no electrical equipment is exposed to contamination by oil,

grease, water or dirt;

• Visually check that no loss of fluids such as lubricating oil and coolant is
apparent;

• Check the operation of all limit switches or cut outs;

• Check that the Automatic Safe Load Indicator (ASLI) is set for its correct duty;

• Check that the correct air pressure is maintained in any pneumatic control

4.1.2 Weekly Checks:

Once a week, when the crane is in use, the following checks as appropriate for the type of
crane should be carried out:

• Checks as required by the manufacturer’s handbook;

• Check the Automatic Safe Load Indicator in accordance with the operating
instructions;

• Visually inspect all ropes for broken wires, flattening, distortion, nesting or
other sign of damage, excessive wear and surface corrosion;

• Check all rope termination, swivels, pins and retaining devices and check all
sheaves for damage, worn bushings or seizure;

• Inspect the structure for damage, e.g. missing and bent bracings on
bridges and strut jibs, bulges, indentations and unusual rubbing marks on
telescopic jibs, cracked welds and loose bolts and other fasteners;

• Check hooks and other load lifting attachments, safety latches and swivels
for damage, free of movement or wear. Check the hook shank thread and
securing nut for undue movement, which may indicate wear or corrosion;

• Check operation and adjustment of controllers;

• On hydraulic machines check for creep of hydraulic rams;

• Check effectiveness of brakes and clutches;

• On wheel mounted mobile cranes check tyres for pressure as well as

damage and wear on wall and tread, also check wheel nuts for tightness;

• On rubber tyred cranes check steering, brakes (both foot and parking),
lights, indicators, horn, windscreen wipers and washers;

• Enter results of checks in the records of inspections. Where applicable,

statutory forms should be used.

4.1.3 Crane Not in Regular Use:

In cases where a crane is not in regular use, it may be necessary to carry out a special
programme of checks before it is used.

A crane that has been out of use in the open and therefore exposed to the weather and
atmospheric pollution, etc. may require an extensive appraisal to ensure its fitness for
work.

The appraisal should include at least the following:

• Any checks that may be recommended by the manufacturer;

• Examination of all crane ropes for signs of corrosion and damage and
ensuring that there is thorough lubrication;

• Examination of all control linkage for evidence of seizure or partial seizure

and ensuring that there is correct lubrication;

• Testing of every crane motion for several minutes without load, each
motion individually at first then by combination of two or more motions
simultaneously as appropriate, and then repeating the test with a load on
the crane;

• Checking the correct functioning of all the crane safety devices;

• Checking of hoses, seals or other components for evidence of deterioration;

The results of all tests in the programme should be documented in the crane records
along with the corrective action taken to overcome any defects prior to the crane being
returned to service.

4.1.4 Reporting of Defects and Incidents:

Crane Operator should report defects and incidents to Lifting Operation Supervisor, who
will take action to rectify any defect and clearance of the crane for further service.
Incidents will be reported as in HSE Procedure Manual 10 – Part 2: Procedure for the
Investigation and Reporting of Incidents.

A crane should not be used unless it has the appropriate current test certificates. Tests
will be required following substantial repairs or alteration, and/or periodically as
prescribed by manufacturer and legislation.

The Safe Working Load should be clearly marked on the crane or the charts affixed
to it. Any lifting attachments should be clearly marked with their Safe Working Loads.

hook, they shall be first brought into a shackle that in turn shall be hung freely from the
hook.

9.3 Shortening and Joining Chains

• Chains shall be jointed only by means of approved devices and never by bolts, wires etc.

• Where it may be required to shorten the chain, then the sling shall be supplied with
shortening clutches, which shall be used in accordance with the manufacturer's
instructions.

9.4 Unslinging

When a load is landed, provision shall be made to ensure there is sufficient room underneath it
(apply wooden blocks) to withdraw the slings, without dragging them or forcing them away from
their position, since this will damage the slings and make them unfit for use.

9.5 Abuse

Slings shall only be used for slinging the loads for which they are designed and in a proper
manner. In particular, slings shall never be used for towing vehicles.

9.6 Checking Slinging

After initially lifting the load off the ground, the Banksman or slinger shall check his slinging to
ensure that the slings are not slipping or liable to slip, and that the load remains slung at the
intended angle.

be subjected to a proof load test (except textile slings*) by the manufacturer and
certified. The SWL and serial number shall be clearly marked on the sling and
the lifting gear, either by tagging, stamping, engraving or embossing. Slingers
shall not use lifting gear unless the SWL is clearly visible.
*
Manufacturer / supplier should issue a Certificate of Conformity (CoC) in addition to the
Declaration of Conformity in case of Textile Slings such as Webbing Slings, Round Slings
…etc.

• For used (second hand) lifting equipment, all should be thoroughly examined by a
competent person at regular intervals and issued a Report of “Thorough Examination
Records”.

MINIMUM BREAKING LOAD (MBL) - The calculated load at which a sample of the item
will break or fail, Working Load Limit is derived form this value.

FACTOR OF SAFETY (FOS), COEFFICIENT OF UTILIZATION, WORKING

COEFFICIENT - It is a factor which is applied to the MBL to determine:
• The WLL depending on the product standards and type of stresses the item will meet in
normal use; and
• The SWL if the conditions of use are more severe than those considered by the product
standards, the competent person will apply an increased FOS, so reducing the value of
SWL from that of the WLL.
