6. GENERAL INFORMATION
1) First identify all separate components and types of Prolyte truss to be used, ensure that you are
fully conversant with this manual before you start using any of these parts, components and
trusses!
2) Never use trusses parts or vital components such as wire ropes (or chains), that show visual
damage, deformation wear or have any other reason to doubt the safe functioning within the
system. Make sure to check each item before each time of use.
3) Make sure that the system is built on solid ground. In situations where it has to be built on grass,
sand or any unstable subsoil, under fill the screw jacks with plywood pads of 300x300x20mm
(minimum size for each screw jack).
4) Check the building site for obvious hazardous objects such as power lines. Keep a safe distance of
at least 8m from those in any possible direction of sway in the wind, or the distance as specified in
the national or local codes or regulations for safe operation of mobile cranes. Always check the
planned tower-building activity with the power-company.
5) Check the building site for obstacles such as lamp-posts, trees or tree-tops, overhead piping, in
house constructions, or any other higher objects that might hamper erection of the towers or
might endanger it when swaying in the wind or so.
6) Check local authorities for possible risks in subsoil, such as low stability peat or bog fillings, sewer
or large drainage pipes, waterlogged soils in slopes etc.
7) Measure the area where the tower needs to be and make sure there is enough room for all
components including the outriggers with the plywood padding (the free and cleared building
site for each tower, needs to be app. 3.5m wide, 7.5m deep and 8m high).(1)
8) The complete tower should be totally level when built. If the tower is not exactly level this may
result in constructive weakness of the system.
9) Avoid dynamic loads. Do not turn the hoist on and off when hoisting the load in place. Lift the
load as steady as possible.
10) Make sure the load can not turn once hoisted in place. Use tag-lines if needed.
11) Make sure the screw jack bracing attachments are placed correctly in alignment to the geometry of
the truss sections.
1Except in the situations of hazardous objects or obstacles as mentioned above.
NOTE
Make sure only one competent person is chosen to be responsible for and in charge of all coordinating
actions and supervising the entire building, erecting and dismantling process.
WARNING
Even if local legislation might be lacking any demands on personal safety, it is strongly advised to use fall
protection-equipment when climbing the system during building, particularly at over 2m high from
ground level, when falling hazards are prominent.
NOTE
The ground pressure on the screw jacks underneath a tower can easily be more than 0,95 ton with dead
load, live load, wind load and full ballast imposed!
Never erect the tower when any doubt remains on the safety of the underlying ground.
