Industrial Ladder Tower Double Width Tower Assembly Guide Industrial Ladder Tower Double Width Tower Assembly Guide
The tower should be manoeuvred into position by hand by
pushing it from the base frame. Never attempt to use any
mechanical equipment (i.e. a forklift etc.) to move the tower.
If it is necessary to lift individual components whilst assembling
the tower, a dependable knot should fasten each item.
Be aware of overhead obstructions – pay particular attention to
any live electrical cables. Ensure that no persons, materials or
tools are on the tower when it is being moved.
Additional care should be taken when moving the tower on
uneven or inclining ground. The use of the castor locks should
be deployed when the tower is in position. When moving the
tower the stabilisers should only be lifted 35mm from ground
level.
Towers under 4m in height are the only towers that
should be moved.
zCheck all components (see component list) are available
and in usable condition.
zDamaged or incorrect components should not be used.
Scale 4. 13 - 18 mph .......................................................................................OK TO WORK ON TOWER
Moderate Breeze: Raises dust, loose paper; moves small branches
Scale 5. 19 - 24 mph ..................................................................................STOP WORKING ON TOWER
Fresh Breeze: Small trees in leaf begin to sway; white crested wavelets form on inland waters
Scale 6. 25 - 31 mph ................................................................................................ DISMANTLE TOWER
Strong Breeze: Large branches in motion; umbrellas used with difficulty; telephone wires “whistle”.
Be aware that wind conditions are a very important consideration when using a tower. Attention must be paid to individual situations
where wind conditions can increase - i.e. when working between buildings, or close to the corner of a building and at open ends.
Never use tarpaulins or similar covers without seeking the correct advice.
This document will provide all users of Lewis Access Towers with
a complete guide to the erection of the Lewis SW (Double Width)
Aluminium Tower, employing the 3T (Through the Trap) method.
The user should read the entire contents of this document before
commencing assembly and pay particular attention to all of the
safety instructions. If the equipment is passed onto another party
a copy of these instructions should accompany the handover.
Two persons are necessary to carry out the erection of the
equipment detailed in this document. It is strongly recommended
that the following items of personal protection equipment be
worn at all times: safety boots (EN345 or BS1870 / 4972); safety
helmet (EN397 or BS5240); gloves. The SWL (Safe Working
Load) for each platform is 275kg, evenly dispersed.
Additional items, such as steps or conventional ladders, must
never be used to gain further height from the platform. The tower
must be climbed from within the structure, on no occasions
should the tower be scaled from the outside. Inspect all the tower
components before each use. Pay particular attention to;
zCastings - check for cracks
zWelds - free from cracks
zTubes/Braces/Rungs - Straight and with indents less than
5mm deep
zPlatforms - no damage, free from debris
zCastors - moves freely, threads free from damage, brake
working
zOutriggers - straight, feet flat
zInspect the equipment for damage regularly, at least daily.
Double Width Tower Assembly Guide
The Lewis Tower is a Class 3 Industrial Tower System
Working on the Tower - The Beaufort Windscale
zIf damage should occur whilst in use, stop work
immediately and isolate the damaged items from the rest of
the tower and contact your supplier.
zCheck the ground on which the tower is to be used is
relatively flat, smooth and capable of supporting the tower.
zThe SWL (Safe Working Load) of the tower is 275kg per
platform, inc the weight of the tower - evenly distributed, up
to a maximum of 950kgs per tower.
zDo not exceed the SWL.
zNever attach safety harnesses or similar safety equipment
to the tower whilst erecting or dismantling the tower.
zDuring assembly, the tower should only be climbed from
inside of the frame dimensions, do not scale the tower from
the outside.
zTools and equipment must be loaded onto the platform
within the confines of the tower dimensions.
zAdjustable legs are to be used for levelling.
zOutriggers should always be deployed when required.
If the area of operation means that the outriggers cannot be
deployed in the recommended position – contact Lewis Towers
or your supplier for advice.
Ballast for Towers up to 12.2m in height, ballast is not necessary

However, the image we have used, is an 8 Rung (2m high) frame.
1.10 Insert the adjacent frame.
1.11 Clip the diagonal braces onto the lowest rungs.
1.9 Clip the diagonal braces onto the lowest rungs.
Assembly Procedure

Assembly Procedure
1.18 Attach the trap door platform approx. 2.2m above ground level. This will be on the 8th
Rung, if you started to build the tower with an 8 Rung Section. If you started to build the
tower with the 4 Rung (1m) frames, then the 1st platform will be placed approx. 4 Rungs
above the frames. This will vary depending on what section you have started to build your
tower with.
1.21 Climb internally up the rungs of the frame through the trap door platform. site with feet through
the platform, so they are resting on the rung of the frame. Fit four guardrail braces on the 2nd
Rung and 4th Rung above the platform. or at approx. 250mm above the platform, then a further
250mm from there.

1.24
1.25 Clip the diagonal braces into position.
1.26 Stand on the platform and ensure the guardrail are securely in place, at the opposite end
of the tower.
1.27 At this point, a platform height of 2.2m has now been built.
Assembly Procedure
1.28 To continue building higher, fit the next set of frames on either side.
1.29 Clip the diagonal braces into place.

1.30 Ensure the frame clips are securely in place.
1.32 Then place the Fixed platform next to the trap door platform, so they are side by side.
Ensure there are no gaps between the platforms. They must be pushed together.
1.33 Climb through the trap door, as you did at point 1.21m. stay sitting on the platform, with
feet rest on the rung below.
Assembly Procedure
1.31 Insert the platform, once the braces are securely in place. The next platform should be
placed approx. 2m above the first. The rungs will vary, depending on the size frames you
have, but should be placed around 2m higher.
1.34 Place the handrails securely into place whilst sitting.
1.35 Stand on the platform, and ensure all braces are facing the correct way, and are securely
in place.

Industrial Ladder Tower Double Width Tower Assembly Guide
1.36 Fit the toeboards securely into place. The Toe board clips to be fitted in all 4 corners of the
platform, then place the wood.
1.37 The tower has now been built!
Assembly Procedure
Dismantling
To dismantle the LEWIS Double Width tower, first remove the toeboard set and send safely down the tower. Remove the furthest
of the four guardrails and diagonal brace. Go directly to the trapdoor platform next to the ladder frame to remove the braces
completely. To fully dismantle the tower reverse the erection procedure detailed in this guide above.
Stability
Towers left unattended or unused for extended periods in exposed situations should be dismantled. Horizontal forces i.e.
pressure exerted when drilling into a building face can yield instability in the tower. The tower must not be used to gain access to a
neighbouring structure. Tower are not intended to be suspended.
Transport and Storage
Components should be transported and stored vertically. Damaged items must be repaired by a competent person. Contact your
supplier for advice.
