Important informationHAKI’s product liability and user´s manuals apply only to scaffolds that are entirely composed of components that have been made and supplied by HAKI.

HAKI’s scaffold systems must not be erected using components of makes other than HAKI or be connected to scaffolds of makes other than HAKI. In such cases, a special study of load-bearing capacity must be carried out. However, HAKI has no objection to the customary addition of scaffold tubes and approved couplers to the scaffold.

Adding components from different suppliers may invalidate the insurance cover.

This user´s manual is based on a minimum of 2 competent erectors.

This user’s manual is to be used in conjunct ion with HAKI training courses.

A user’s manual should be provided to the user together with the scaffolding.

HAKI reserves the right to make technical modifications on a continual basis.

The latest versions of HAKI user’s manuals can be downloaded from our website, www.HAKI.com.

For scaffold structures that are not covered by this user´s manual, please contact HAKI’s technical department.

The HAKI Bridge System (HBS) is designed for loadings up to 7.5kN/m2. The HAKI Bridge System is designed to be used as a pedestrian bridge over rail tracks/roadways and similar projects, or to act as a spine beam for scaffolds, or to support temporary roofs. It is a perfect complement to the HAKI Public Access Stair (PAS).

All HAKI Systems have been designed to conform to current Brit ish and European Standards. The loading criteria contained in this manual have been calculated according to current European Standards, SS-EN 12810 and SS-EN 12811.

The HBS incorporates the use of HAKI Universal system components including the single ledgers, ledger beams, and guardrail frames. The handrails (barriers) are specially designed for use on a HBS and PAS system. All components for the HAKI Bridge System are hot-dip galvanized with the exception of the insert panels and AL planks.The HBS can be erected in bay widths of 1250mm, 1655mm, 1964mm or 2500mm (where permitted) and bay lengths of 2500mm or 1250mm with the minimum of tools.

The HBS may be constructed;1. on a temporary scaffold at ground level, then lifted into place.2. on a temporary scaffold at finished level.3. by a progressive ‘roll-out’ method.

BASIC INFORMATION

Informat ion on safety when erect ing and dismant ling1. Carry out local risk assessment and method statement.2. Make sure that all lift ing equipment to be used, e.g chain hoists, lift ing ropes, pulley

blocks, etc., has been thoroughly tested and approved by an outhorised person inaccordance with local regulat ions.

3. Check that tools and protect ive equipment are available at the worksite.4. Wear appropriate personal safety equipment at all t imes, e.g safety harnesses,

proper independence lifelines with suitable fixings, etc.5. When erect ing and dismant ling a scaffold, robust temporary decking must be used

as temporary platforms for the scaffolders.6. Always make sure that the safety locking devices that prevent a plat form lift ing off

have been act ivated once a platform has been installed.7. Study all relevant instruct ions or safety direct ions from the manufacturers of the

various scaffolds that are to be used.8. Never climb up a scaffold from the outside. Always use the stairs, ladders or

climbing frames that are designed to provide access to the upper decks from theinside of the scaffold.

9. lf the scaffold is to be used outdoors, erect ion or dismant ling work must bediscont inued if the weather condit ions are too bad. Make sure that all loosecomponents are properly fixed before leaving the scaffold.

10. Scaffolding work must be carried out by "competent operat ives" under thesupervision of a "competent person".

11. Lift ing equipment must not be attached to a free-standing scaffold.12. Beware of any overhead power lines nearby.13. Always observe and comply with the regulat ions issued by the local authorit ies

concerned.14. Erectors/dismant lers should always be clipped to a single ledger or ledger beam

during erect ion/dismant ling. Reference should also be made to sect ion ”PersonalSafety Equipment” in the Universal User manual.

ERECTION BY LIFTING

1. Construct low scaffold of sufficient width to comfortably walk around the HBS.

Before erect ing the scaffold, check and flatten out the ground. Check the levels in both the transverse and longitudinal direct ions using a spirit level and adjust using the base jacks.

NOTE: Clamps should not be OVERTIGHTENED. Bridge should be permitted to ‘slide’ in its longitudinal direction.

Connection to End StructureLedger Adjustable should be erected above the Head Plate of the Tripod Head Adaptor.The first 770mm Single Ledger should be erected below the Head Plate of the Tripod Head Adaptor. The next 770mm Single Ledgers should be erected at al-ternate set of pockets of the Tripod Leg.

NOTE: If the HBS system is going to be used near a railway it is essential that the actual HBS isconnected to the main structure (PAS) at each end using Adjustable Ledgers. This allows the HBS to ’float’ in its longitudinal direction so that natural horizontal effects are not transmitted into the main structure.
