SAFE WORKING LOADS AND WORKING HEIGHTS
The safe working load at each level of platform is 360kg
evenly distributed, regardless of whether one or two platforms are installed. Therefore, even if two platforms
are installed side by side, total cumulative load shall not exceed 360kg distributed.
The total loading on the tower structure should not exceed
720kg. Normal maximum platform height for indoor use is 12m for Double Width, and 8m for Single Width. For
outdoor use, the maximum height is 8m for Single and Double Widths.
***
USAGE ADVICE
We recommend a minimum of two people to assemble,
dismantle and move the platform tower.
Check that all components are on site and in good working
order.
Ensure that the assembly location is checked to prevent
hazards during assembly, dismantling or moving and while working on the tower. Particular attention should
be given to the ground condition, whether level or sloping, obstructions and wind conditions. The ground
condition must be capable of supporting the tower structure.
Towers must always be climbed from the inside of the
assembly using the ladder.
Adjustable legs must only be used to level the tower.
If the adjustable legs are to be extended by more than 150
mm; a risk assessment needs first to be undertaken by a competent person.
Lifting of components must be done inside the effective
base area of the tower; components are normally hoisted using a rope.
Moving the tower must only be done by manual effect from
the base of the tower.
When moving tower be aware of overhead hazards (e.g.
electric cables).
No personnel or material to be on the platform whilst the
tower is being moved.
Beware of horizontal loads which can lead to instability
of the tower. The maximum side force is 20kg.
When tying-in the tower, attach a tie to each upright at
4m height intervals. Ensure that couplers are suitable for 50mm diameter aluminum tube.
Do not use boxes or steps to gain additional height. If
extra height required, contact your distributor to get extra components.
Do not lift or suspend an assembled mobile tower.
Damaged components or components from other tower systems
must never be used.
Stabilisers should always be fitted when specified. Use
the stabiliser shown on the component list according to the tower height.
When wind exceeds Beaufort force 4, cease using the tower.
If wind is expected to reach Beaufort force 6, tie tower
to a rigid structure.
If winds of Force 8 are forecast, dismantle the tower or
remove to shelter.
***
Force <>Peak mph <>Peak km/h <>Peak m/s <>Guidance
4........<>18..............<>29.............<>8.1............<>Moderate breeze - raises dust & loose paper
6........<>31..............<>50.............<>13.9..........<>Strong breeze - difficult to use umbrella
8........<>48...............<>74.............<>20.8..........<>Gale force - walking is difficult
***
Do not strike or hammer components. Do not throw or drop
onto hard surfaces.
***
MOVING TOWERS
To Move the tower to a new position, first prepare the
tower.
Check that the wind speed does not exceed 29km/h (8.1m/s).
Ensure the tower is empty (material and personnel).
Check for overhead obstructions including electrical
cables.
Raise the stabiliser feet (only enough to clear
obstructions).
Taking care to ensure tower stability is maintained,
insert any extended adjustable legs completely into the frame.
Release the castor brakes.
Carefully move the tower by manually applying force at the
base. Do not use mechanical means to move the tower.
Once positioned prepare the tower for use.
Check and adjust as necessary to ensure all castors and
stabilisers are in firm contact with the ground.
Check that the tower is vertical using a spirit level.
Reapply the castor brakes.
