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 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 should be capable of supporting the tower structure.
• Towers must always be climbed from the inside of the assembly and using the built-in
ladder if provided.
• Adjustable legs should only be used to level the tower.
• Lifting operation should be done inside the effective base area of the tower.
• Moving the tower should only be done by manual effect from the base of the
tower. When moving tower be aware of overhead hazards (eg. electric cables).
• No personnel or material should 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 assembled mobile tower.
• Components are normally hoisted using a rope. Always lift within the tower structure
or within the base rectangle defined by the stabilisers.
• Damaged components, or components from other tower systems should never be
used.
• Stabilisers should always be fitted when specified. Use the type of stabiliser shown
on the component list according to the tower height.
• When wind exceeds Beaufort force 4, cease using the tower. Wind speeds:
CARE AND MAINTENANCE OF THE TOWER AND COMPONENTS
• Keep all equipment clean, especially spigots and sockets where frames join. Spigots should fit easily into stocks. Lubricate with light oil.
• Remove dirt or paint from adjustable legs with a light brush, Lightly oil the leg locks.
• Do not strike or hammer components. Do not throw or drop onto hard surfaces.
• Lightly oil spring mechanism of the hooks.
• For transport and storage, components are best stored vertically.
• Damaged parts should be repaired or replaced, contact your supplier.
TOWER COMPONENTS REQUIRED
The following tables show a full list of components to build the tower to the platform height specified, complying with the requirements of EN 1004 and Work at Heights
Regulations (WAHR). Braces, platforms, guardrail, bracing frames and toeboards are length specific; 2m, 2.5m or 3m. Three unit weights in ascending order are given for these
items, for 2m, 2.5m and 3m respectively. Other components are common to towers of all lengths, and their unit weights are also given. Total self-weight of towers are indicated,
according to length and height.
ALTERNATIVE CONFIGURATIONS
Single Width Tower
The build process for the Single
Width Tower is the same as
double width, with the exception
of - 2 diagonal braces are used
per extension set, rather than 4.
See attached figure for bracing
details.
Towers Above 4m
To build towers with platform
heights greater than 4m, build as
shown up to step 8. Repeat
steps 7 and 8 until desired
height is reached. Finish building
the tower by completing steps 9
and 10.
Towers with “uneven” platform
heights (3m, 5m, 7m etc)
Build as shown up to step 6 (3m
platform) or step 8 (5m). Install
1m frames and guardrails using
the 3T method described in step
6. Install platforms at working
level and guard using guardrail
frames and braces. See section
1 for exploded view of the
assembly.
