Danger of Work @ height

Work at heights is the most common cause of death in the workplace. causes 12% of all work related accidents.

causes 30% of all work related major injuries.

causes 59% of fatalities in the construction industry.

Machinery directive 2006/42/EC

1.1.2 Principles

eliminate any risk throughout the foreseeable lifetime of the machinery

including the phases of transport, assembly, dismantling, disabling and scrapping

1.5.15 Risks of slipping, tripping or falling

Parts of the machinery where persons are liable to move about or stand must

be designed and constructed in such a way as to prevent persons slipping,tripping or falling on or off these parts

EN 13000 Cranes Mobile Cranes

4.2.9.3 Access

access to components or parts of the crane for maintenance, inspection,erection and dismantling, shall be in accordance with EN 13586.

Deviating from 6.6 of EN 13586:1999, side protection for platforms and walkways

up to a height of 2,50 m is not required if either:

a) a safe access with related ergonomic handrails or handholds for three point support are

provided or

b) the free standing width of walkways or platforms is at least 0,5 m.

Lattice boom fall protection

Rigging Rigging jobs

1. Pinning of boom sections

2. Locking / Pinning of Main boom- or Jib pendant bars

3. Attachment of boom sections

4. Connection of pendant bars to A-Frame and Hoist 2-traverse

5. Raising of jib (connect assistance ropes w lifting rope)

6. Jib relaps cylinder connection

7. Start-up of Hoist H1 / H3

8. Attach bracings

9. Pulling of lifting- and rigging ropes

10. All types of inspections/ Maninainance on Pendant bars/Rollers/Hoists

11. Adding additional pendant bars (e.g. Jib pendants)

Manual instructions

all walkways are emergency walkways... The user is obliged to use additionalsafety devices as aerial work platforms or scaffolds where necessary

Lattice boom fall protection

Considered solutions

1. Conventional walkways with foldable wire handrail (existing) must be on both sides and stiff

2. Simply wider walkways (>0.8m) is tolerated on many constuction sites, but not in line with all regulations

3. Walkways and additional nets on inside complete boom section width not in line with standards for side protection

4. Additional nets and handrails on sides of boom sections not in line with standards and extremely expensive

5. Walk-Wagon along walkways (Tram-System) interferes strongly with operational needs. Only one person can work.

6. One rope at 1.6m along the complete boom with PSA in line with standards, but does not work for first rigging

7. A combination of single, foldable ropes per boom section in 1.6m withPersonal Protective Equipment

fulfilling with standards and in line with operational requirements
