• Smooth steel bar is to be double wrapped in the chains.

• Screw jacks are to be lifted in bins or are to be stacked neatly on a pallet and strapped in place using steel wrapping.

control)

• The doggers should take particular attention and advise the crane driver of the hook locality so as to ensure under all circumstances that lifts are to be within the site confines.

• The doggers will ensure that all the lifting gear is checked daily, and is in good working order. Should any of the lifting gear require attention, the doggers are to be advise PFEIFFER CRANES immediately.

• The ground doggers should maintain a clean, general lifting area at all times.

• At all times doggers should be conscious of attaching lifting chains, or rigging in such a way that there is no likelihood of the load becoming loose and falling on co-workers.

• COLUMNS to be lifted from approved and designated areas. Storage of columns should be such that they cannot fall. Doggers are to ensure bolts on lifting loop are maintained and are correct type.

• LIFT WELLS Doggers are to ensure that they know the weight of form work shutters prior to lifting; all shutters should have their weights clearly marked on them, and lifting points only. Doggers must familiarize themselves with the form work procedures, prior to lifting any form work.

• The lift box should have it’s weights clearly marked on it, and for stripping

purposes should be totally free from the concrete walls prior to lifting (Prior to attaching chains). The crane driver should not winch the crane more than half a tonne, above the weight of the box (due to restriction of load). It is up to form workers to free the load.

• Doggers are to study the steel schedule prior to attaching chains and identify bundles of steel to satisfy themselves that the weights are within the crane’s capacities.

• FORMWORK SHUTTERS INSTALLATION/REMOVAL. Climbing on shutters or column boxes is not allowed. Doggers will not lift prefabricated panels or cages unless correct procedures have been followed.

• Wall shutters should not be lifted from designated lifting point. (as per engineering drawings)

• Prior to lifting shutters, the dogger is to check that there is no loose

H

material on shutter (ie concrete, timber, etc). At the discretion of the dogger, a tag line is to be attached to the bottom part of the shutter during the installation when it clears the concrete.

• To dislodge shutter from concrete, and remove bars/bolts, apply load of approximately 20% more that weight of shutter. Prior to lifting, the dogger is to ensure there is no loose material on the shutter (ie concrete spills or y-bars etc).

• At the discretion of the dogger, the tag line is to be attached to the bottom of the shutter when it is clear of the concrete.

• If wind conditions are suitable not exceeding 25kph then the shutter/formwork can be lifted, or placed in position. (This condition is subject to variables of wind direction, position of lift etc.)

• The decision to lift the shutter/formwork is to be made by the dogger and crane driver in consultation with the Project Management. (Laying the shutter flat, may reduce the wind resistance).

• When a tag line is used to stabilize the shutter, the dogger is to guide it into position, making sure the immediate area is clear of personnel.

• After lowering the shutter to the appropriate area for storage, the dogger is to ensure that the shutter is stored into its nominated rack, and that it is stable and safe, prior to releasing the chains.

• GENERAL. Concrete kibble is to be lifted from the shutter on the bridle. If the vibrator is to be carried out with the kibble, then it should be attached to the kibble by a chain of a least 7mm in diameter. The kibble should be cleaned thoroughly after every use.

• False work frames should be stacked in an approved manner. When bundles of frames are lifted, the chains should be put around the main chords, and between the bracing so that if the frames slip they are captive within the chains.

• Bundles of plywood should be lifted with two chains. The chains should be choked around the bundles of ply.

• Stacks of timber should also be lifted with two chains, and choked around the pack. Packs of timber should be strapped, or have a piece of ply wood nailed to the top to maintain the integrity of the pack.

Sling Loads

VH

• Blocks should be lifted using a block cage. Care should be taken that the block cage is lowered centrally over the pall blocks. When the cage is removed from the blocks, care should be taken to ensure the tynes are placed in the correct position for the return journey.

• Scaffolding should be lifted on stillages, and chains should choke the scaffold items around the pallet. If scaffolding pies are to be lifted with a pallet, then it needs to be doubly wrapped.

• Alloy mobile scaffolding are NOT to be lifted (it is illegal). • The procedure for lifting/operation of Man Boxes (with personnel) is:

1. Prior to lifting the Man Box, a zoned area is to be demarcated, and (if the procedure dictates), a spotter allocated to the area, and no personnel are allowed into the area whilst the lift work is in progress

2. All personnel in the Man Box by a harness, (connected to the main rig). All tools are to be secured to prevent them from falling out of the Man Box.

3. Man Boxes should be lifted with four chains on the lifting loops. If the dog box is emptied from the rear loops, four chains should be re-attached to the dog box, so it can be positioned in the required area.

Lifting procedures: Prefabricated Reinforcement Steel Mats & Column Cages.

• You are instructed not to lift any reinforcement steel mats or column cages in a vertical position, unless;

• A competent person (ie. Structural Engineer) has assessed and certified the lifting system of each wall mat or column cage or

• Consultation between the dogger and Pfeiffer Cranes site representative and

• Lifting of wall mats or column cages can only occur if the dogger has assessed the load of rigging requirements prior to the lift and it is safe to do so.

procedures on Man Box safety, and the Safe Work Method Statement for lifting and working from a man box. Before lifting PRE-CAST PANELS, ensure onsite procedures are in place and adequate for the job.

16

Dual Lift Procedures

• Crane tip over.

• Injuries to people

• Damage to property

• Damage to equipment

H • Decrease the load chart capacities by 20% for each crane.

• The lift weights of both cranes in relation to the load are to be calculated and a working procedure drawn up between the two crane operators and riggers concerned. The procedure is to be signed by all concerned.

• The doggers/riggers are to be attaching the chains to the load in preparation for the lift.

• One rigger is to take control of the lift, (and both cranes), at this stage.

• The rigger in control is to instruct the both crane operators to hoist up, approximately 1 meter off the deck.

• The rigger at this stage is to check with both crane operators for each crane’s actual hook weight, to ensure cranes are in their capacity to move the load.

• If the actual hook weights are too heavy the load is to be placed back on the ground and the chains re-located until in correct position.

• Once both cranes have the correct weight for the radius the control rigger is to signal the hoist up and control the lift to it’s set down position.


• Crane Crew

• Site Management

17

Loose Items • Impact injuries • Crushing injuries

• Damage to property

• Damage to equipment

SR • Loads of loose items such as scaffold clips must be raised improperly constructed boxes branded with the Safe Working Load (SWL).

• Do not lift loads of the kind in 200 litre drums because: o These drums have no rates lifting capacity. o It is not possible to know the condition of the base of the drum.

(They have usually been discarded because they are unfit to hold liquid).

o The holes cut into the sides for the sling or hooks often pull through under the weight.

o The sharp edges of the holes can cut through a sling.

To find the minimum area and dimensions required under each outrigger;

Area = 0.65 x (Cm + L)

P max.

Example

When crane mass (Cm) = 60 tonnes

Load to be lifted (SWL in Chart Range) (L) = 20 tonnes

Where maximum permissible ground pressure e.g. P max = 40 P.max

Area = 0.65 x (60t + 2Ot) = sq. m 40t per m2



We, the undersigned, acknowledge that we have attended the toolbox meeting and are fully conversant with the safety precautions included in this Safe Work Method Statement. We understand that we are required to be in a fit state to work on site. We agree to keep a copy of this statement in each tower crane at all time as a point of reference and to allow review and revision as necessary.
