Inspection Care & Maintenance

Alto Access equipment is designed and manufactured to the highest standards in the industry and is

stronger, more robust and safer than any comparable competitor product. Properly cared for, it will give

a long and productive service life.

· The equipment should be inspected and maintained as outlined in the “ALTO Ultima® Tower Inspection

Procedures”. A free downloadable copy is available at www.altoaccess.com/downloads

· Equipment should always be inspected before and after each use.

· Whilst Alto Access equipment is extremely robust, care should be exercised in loading, transporting

and handling components to avoid damage or injury to either the equipment or persons.

· Repairs should only be carried out by Lakeside Industries Limited or their authorised repairers.

· In case of any doubt as to the integrity of any items of Alto Access equipment, the part should be

withdrawn from use, quarantined and subject to detailed examination to determine whether repair

or replacement is required. If returned to the factory, Lakeside Industries Limited will provide a free

of charge evaluation of any damaged components.

Safety

Check that all of the necessary components and equipment for the particular tower configuration to be

built are on site, undamaged and functioning correctly. Damaged/incorrect components must not be

used.

· Check that the surface on which the tower is to be located is capable of supporting the tower and its

payload.

· The safe working load of the tower is 2,500kg including its own weight. The maximum safe working

load of any individual platform is 324 kg evenly distributed.

· If the tower is to be used in an application outside the scope of EN1004, contact your supplier or the

manufacturer: Lakeside Industries Limited, for advice on loadings. Tel: +44 1527 500577 or Email:

[email protected].

· Towers must always be climbed from the inside using the built in ladders (or Alto stair units if

applicable). If the work carried out from the tower requires frequent carrying of equipment and

materials up or down the tower, an Alto stair tower should be used in preference to a ladderspan

tower.

· The tower must be levelled when erected using the adjustable jack or castor legs.

· Two or more persons are required for the safe erection and dismantling of a tower.

Page 4ALTO Ultima®Tower |Assembly Guide

· It is recommended that the tower be tied in when left unattended.

· Always comply with the Work at Height Regulations 2005 when erecting, dismantling & using the

tower.

· When lifting components, always use reliable lifting equipment and fastening methods and always lift

from within the footprint of the tower structure to prevent risk of the tower overturning.

· See “Moving the Tower” below for safety guidelines affecting the relocation of the tower.

· Beware live electrical installations, cables, moving machinery or other obstructions when erecting,

dismantling or using the tower. The tower is a conductive metallic structure.

· The maximum safe lateral force for a freestanding ALTO Ultima® tower is 30kg.

· Do not use boxes, ladders or other items to gain additional height.

· Do not stand on guard rails for any reason.

· If the tower is to be used in connection with hoisting arrangements, this is outside the scope of

EN1004 and requires specific advice from the manufacturer to ensure safety.

· Contact the manufacturer Lakeside Industries Limited for advice on loadings Tel: +44 1527 500577 or

Email: [email protected].

· Fit guard rails to every platforms.

· Fit toe boards to all working platforms.

· Intermediate (rest) platforms are installed every 2m.

· The tower is not designed to be sheeted. Sheeting massively increases wind loads on the structure.

If sheeting is to be attached, contact the manufacturer Lakeside Industries Limited for advice on

loadings Tel: +44 1527 500577 or Email: [email protected].

· The tower is not designed to be lifted or suspended.

· Every erected tower must be inspected at least every seven days and any tower which has been left

unattended should be inspected before use to ensure that:

1 no components have been removed or relocated incorrectly;

2 the tower is still vertical; and

3 no environmental or other factors have arisen which will influence safe use of the tower.

· Unattended towers should be tied in to a rigid structure.

· Stabilisers or outriggers and ballast shall always be fitted when specified.

· Where there is insufficient clearance to fit the specified stabilisers, contact your supplier or the

manufacturer for specific advice. Where ballast or kentledge is used, it must be of solid material,

placed on a platform on the lowest rung of the tower and secured against unauthorised removal.

Wind Speeds

Persons using or responsible for towers must beware of the effect of wind on the structure. Wherever

possible, as a precaution, it is advisable to tie the tower in to a rigid structure if it is to be used where it is

exposed to potential windy conditions. Users should beware the potential tunnelling effect of open ended

or unclad buildings and narrow openings between buildings. We recommend that the use of the tower is

discontinued in conditions where the wind speed is above 17mph (force 4).

Erecting & Dismantling the Tower

All Alto towers must be built and dismantled in accordance with the step by step instructions in the

following pages corresponding to the particular tower configuration involved and having regard to the

working at height regulations and Health & Safety legislation.

Moving the Tower

Before moving the tower, its overall height should be reduced to 4m working platform height or less. No

persons, tools, equipment or materials shall be permitted to remain on the tower when it is being moved.

The tower should only be moved by pushing it by the lowest frames.

When moving the tower users are to be particularly careful of the following:

· Obstructions, moving machinery or electrical cables and equipment

· Not to move the tower in wind speeds of 18mph (force 5) or above

· The effect of rough, uneven or sloping ground on the stability of the tower

· Locking and unlocking the castors to allow and prevent the tower moving at appropriate times

· After completing the movement, use a spirit level to ensure that the tower is vertical and safely

supported on an appropriate surface

· After completing the movement check that the tower is correct and complete.

Diagonal braces must always be located

with the claw opening facing down.

Horizontal braces must be located with

the claw facing either down (on the rung)

or outwards (if on the upright).

All braces are fitted with spring loaded

pins that automatically lock the brace

into position when attached to a tower.

Brace hooks must be located either over

the rung screw heads, between 2 screw

heads or between the frame upright and a

screw head to prevent lateral movement.

Frames must always be assembled with

the offset conical head fitting pointing

inwards towards the centre of the tower.

Stabilisers should always be attached to

the tower so as to maximise the base area

of the tower structure. Set the stabilisers

so they form a square around the tower

as per the diagram below. The correct

size stabilisers must always be used - see

component schedule for details.

Ultima®Anchor Point

The Alto Ultima Anchor Point is an integrated part of an Alto

Ultima frame. It is designed for attaching personal protective

equipment for preventing and arresting falls from height of

a single operative from a tower comprised entirely of Alto

Ultima components.

The Alto Ultima Anchor Point is an EN795 certified type A

device used to anchor a safety harness, or restraint belt via a

lanyard, to prevent the user reaching a position where a fall

is possible (restraint). It is not intended for fall arrest unless

the lanyard is fitted with an energy absorber conforming to

EN355 connected to the anchor using EN362 connectors (hooks, karabiners etc.) and the operative is

wearing a compatible BS EN 361 safety harness and any other relevant PPE.

All testing of anchor points and fall arrest systems is based on a 100kg mass. Users of over 100kg in

weight should seek advice as to whether the equipment is suitable for their safe use. Users of over 100kg

should seek to limit lanyard length to the shortest possible length to minimise arrest forces to below 6kn.

Read the separate instruction manual before using the Alto Ultima Anchor Point. The use of the device

contrary to the manual poses a threat to life.

Ensure that all users have appropriate training and certification before use. Before use – visually inspect

the anchor point for the following points:

· Ensure the system has not been modified/tampered with.

· Check the legibility of the product markings

· Visually inspect the anchor point and the frame that it forms part of for physical damage.

· Check for signs that the anchor has been used in a fall arrest event. Typically this will be evidenced by

the anchor being bent or showing dents in the inner surface of the anchor.

· Check all components for distortion/dents. Ensure that this does not affect the fitting of the steel

anchor plate.

· Check all the steel anchor plate fastenings are tight.

· Check for any general corrosion.

If there are any doubts arising from pre-use inspection, the device must not be used. Report the issues

to the equipment supplier.

As part of your risk assessment you MUST have in place a rescue plan to deal with any emergency, which

Page 8ALTO Ultima®Tower |Assembly Guide

may occur during use. Access to the user - directly or indirectly - and their safe retrieval is of paramount

importance, including preparations for dealing with potential Post Fall Suspension Syncope

Ensure that there is sufficient fall clearance below the anchorage connector to arrest a fall before the

user strikes the ground or an obstruction. When calculating fall clearance, account for a MINIMUM 0.5m

safety factor, deceleration distance, user height, maximum deployed length of lanyard/SRL, and all other

applicable factors.

3T Method Explained

The “3T” or “through the trapdoor” method is one of the two permitted ways of assembling a tower

without the assembler being at risk of falling. This tower is a 3T tower.

Tying In

Towers must be tied into a suitable rigid structure once they go beyond the freestanding working heights

specified in EN 1004 2004 - 8m working platform height outdoors and 12m working platform height

indoors - or if the tower is unstable or is in danger of being unstable.

Standard scaffold tubes and fittings can be used with the Alto Access products. Ties should be spaced at

no more than 4m intervals. Ties must be rigid and be secured to both frame uprights. For further details

regarding tying in, please contact your supplier or the manufacturer: Lakeside Industries Limited.

Step 1:

As each new level of platform is installed, the operative

takes up a working position in the trap door of the platform,

standing on the ladder and leaning back against the edge of

the trapdoor aperture.

Step 2:

From this position the operative fits the horizontal braces

500mm and 1000mm above the platform level (i.e. on the first

and second available rungs). If the far end of the guardrail

braces don’t fully engage when they are put in place, the

operative fully engages it when first climbing up onto the

platform. This process ensures that operatives never have to

stand on an unguarded platform.
