Wind has a significant impact on the stability of mobile access towers since it places loads on the tower that can cause it to overturn.

You should stop working and disassemble the tower if the average wind speed surpasses 17mph (Beaufort 4, 27km/h or 7.6m/s).

However, as part of your risk assessment, verify the weather prediction to ensure that the weather conditions, especially the projected wind speed, allow
you to proceed. 

Never cover a mobile access tower with nets, boards, or sheets.

Never use nets, boards, or sheets to cover a mobile access tower.

These act as sails, and they can easily cause the tower to overturn even in mild winds.

If you're working with huge materials like signs, roofing panels, or cladding, you'll want to be extra cautious.

Consider the site's location. It's critical to keep an eye on local wind conditions and wind speed.

When employing towers between high buildings or inside partially open structures like hangars, tunnels, or partially clad buildings, exercise caution.

The wind speed can be greatly increased due to the funneling effect.

Wind speeds can also be increased by the surrounding terrain, such as being at the top of a slope, hill, escarpment, or cliff, being near estuaries or the
sea, being near woodland, or being in open country.

If the movable access tower is to be installed on a tall structure or building, the wind speed at the top could be much higher. 

Each order will include an installation manual, dimension drawings, a health and safety document, and an emergency contact number for IAE help.

The above documentation will always be included with all tower products on hire and should be provided by any hirer, dealer or manufacturer as standard.

Never use any type of access equipment if none of the following has been provided to you prior install.

Don't put your or others' safety at danger.

The following rules must be followed while hiring any 'Welltech' branded tower from IAE:

Internal Use: Any single or double width structure greater than 2.6m must have
stabilisers fitted.

External Use: Stabilizers are required for any single or double width structure
of any height. 

All persons working at height are required under the Work at Height Regulations to be proficient in the use of the appropriate equipment and to be able to demonstrate their competence and use of the tower or podium.

To obtain more height on a mobile tower, never utilise the adjustable legs.

The adjustable legs' sole purpose is to level the tower on uneven or slanting terrain.

At least one adjustable leg should always be on minimum extension.

Please contact a member of the IAE team, and we will be more than happy to assist in upgrading your current tower to the appropriate height. 

If you're installing a ‘Welltech’ branded mobile access towers , start with the
shortest frames at the bottom, such as 2 rung frames at the bottom, 3 rung
frames in the middle, and 4 rung frames on top.

This will ensure that the guardrails are installed at the proper heights throughout the process.

All ‘Welltech’ branded products supplied by IAE require the following methods to be applied:

Single Width tower : Each platform has a trap door that you can enter via
(Ladder rung frame side)  

Double Width tower: Climb up the ladder rung frame on top of each platform, which should be no more than 2 metres apart.

You must climb through the trap door at the last platform height (Ladder rung frame side)

Safety for you and others.

Toe boards must be installed on the tower working platform and any other
platform if a risk assessment has determined that materials could fall from the
platform and injure someone below.

Even at low platform heights, this risk may occur. 

EN1004-1 (BS/EN1004:2004 in the United Kingdom) is the European standard for prefabricated movable access and working towers.

It replaced the withdrawn British standard BS1139 Part 3 and was issued in 2004.

Standard mobile towers in the height range of 2.5m to 8m for external (outdoor) use and 2.5m to 12m for interior (indoor) use are covered by EN1004 standards. 

The following access tower height ranges are available from IAE:  

Single Width   : 1.41m – 6.98m 

Double Width: 1.41m – 12.55m
