Assembly & Inspections

Do scaffold towers need regular inspections?

Yes. Scaffold towers should be inspected after assembly, before use, and at suitable intervals by a competent person.

What should I check before using a scaffold tower?

Check braces, guardrails, platforms, castors, stabilisers, trapdoors, and ground conditions before use.

Common Scaffold Tower Problems

Why does a scaffold tower wobble?

A scaffold tower may wobble if it is not level, incorrectly braced, overloaded, or standing on unstable ground.

Why is my scaffold tower unstable?

Instability is commonly caused by uneven ground, missing braces, unlocked castors, or incorrect assembly.

What should I do if a scaffold tower sinks into the ground?

Stop using the tower immediately and reposition it onto firm, stable ground.

Can scaffold tower wheels fail?

Yes. Damaged or overloaded castors can fail and should be replaced immediately.

What happens if a scaffold tower is overloaded?

Overloading increases the risk of structural failure, instability, and overturning.

DIY vs Trade Towers

What is the difference between DIY and trade scaffold towers?

DIY towers are designed for occasional domestic use, while trade towers are built for regular professional use.

Are trade scaffold towers stronger than DIY towers?

Trade towers are generally designed for heavier-duty work and more demanding environments.

Can DIY scaffold towers be used commercially?

Only if the tower complies with the required safety standards and is suitable for commercial use.

How long do aluminium scaffold towers last?

High-quality aluminium scaffold towers can last many years when maintained and stored correctly.

Are aluminium scaffold towers better than steel?

Aluminium towers are generally preferred because they are lightweight, corrosion-resistant, and easier to move.

Can scaffold towers be used commercially?

Yes. Professional scaffold towers are widely used across construction, maintenance, decorating, and industrial work.

What is the maximum weight a scaffold tower can hold?

Most aluminium scaffold tower platforms have a safe working load of approximately 275 kg per platform.

Can one person assemble a scaffold tower?

Some compact scaffold tower systems are designed for one-person assembly.

What scaffold tower is easiest for DIY users?

Compact folding aluminium towers are commonly chosen for domestic decorating and maintenance work.

Are scaffold towers safer than ladders?

Scaffold towers generally provide a larger and more stable working platform than ladders.

Ground Conditions & Stability

Can I use a scaffold tower on grass?

Yes, but only if the ground is firm, level, and capable of safely supporting the load.

Can I use a scaffold tower on gravel?

Only if the tower remains level and fully supported without sinking or movement.

Can scaffold towers be used on block paving?

Yes, provided the paving is stable, level, and strong enough to support the tower safely.

Can scaffold towers scratch floors?

Castors may mark delicate surfaces, so floor protection may be required indoors.

Can I use a scaffold tower on a slope?

Most scaffold towers should only be used on level ground unless specifically designed for uneven surfaces.

Can I put bricks or blocks under tower legs?

No. Use proper adjustable legs or base plates only.

What are stabilisers?

Stabilisers are support legs designed to improve tower stability and reduce overturning risk.

Do scaffold towers always need stabilisers?

It depends on tower height, platform length, and configuration. Always follow the manufacturer's instruction manual.

What causes scaffold towers to tip over?

Overreaching, strong wind, uneven ground, unlocked castors, and missing stabilisers can all cause overturning.

Can scaffold towers be used on driveways?

Yes, if the surface is level, stable, and able to support the load safely.

What scaffold tower is best for uneven ground?

Some scaffold tower systems are designed with adjustable legs or stabilisers for uneven surfaces.

Do scaffold towers need stabilisers?

Many scaffold towers require stabilisers depending on tower height and configuration.

Indoor vs Outdoor Towers

What is the difference between indoor and outdoor scaffold towers?

Indoor scaffold towers are usually smaller and designed for restricted spaces, while outdoor towers may require stabilisers and additional safety measures.

Can indoor scaffold towers be used outside?

Some indoor towers can be used outside if ground conditions are suitable and the tower is rated for external use.

Outdoor scaffold towers should be stable, properly braced, and suitable for external weather conditions.

Ladders

What is an extension ladder?

An extension ladder consists of two or more sliding sections that can be extended and locked into place to reach higher elevations. It is designed to provide access to areas that are out of reach for standard or step ladders. Each sliding section allows the user to adjust the intended working height.

How do you set up an extension ladder?

An extension ladder requires leaning against a wall to support you as you climb. To use it safely, you should ensure the ground is stable, and the ladder is firmly in place.

What is the tallest extension ladder available?

Our tallest extension ladder reaches a height of 10 metres.

What ladder height will I need to reach my gutters?

If you live in a bungalow, in other words, a single-storey home, you can reach your gutters with a 3-metre ladder. 2 or 3-storey houses will require an extension ladder that can reach six or 7-metres or more.
