ALTO HD Ladderspan Tower

Built for everyone...and everything!

The Alto HD Ladderspan Tower is the ultimate industrial aluminium mobile access tower on the market today. The most robust form of non-powered mobile access equipment available, the Alto Heavy Duty range has led the way since its creation nearly 40 years ago.

Thanks to its colossal 2.5 tonne loading capacity, the Alto HD tower can cope with almost every job able to be done on a mobile access tower.

The Alto HD Tower range is the pinnacle of safe, strong, sturdy working-at-height access.

Tower Loading

The Alto Heavy Duty access tower offers a significantly higher total loading capacity compared to competitor towers, making it more suitable for demanding professional applications. Competitor tower loadings range from 650 kg to 950 kg. Now, just think, which tower would you rather be working on 12 metres up in the air?

12 m

Free standing Height

Limited only by the EN 1004 standard, the maximum free standing platform height is 8 metres for outdoor use (where the tower is exposed to wind loads) and 12 metres for indoor use (in sheltered conditions with negligible wind). Want to build it higher? No problem. Contact us today to discuss your options, or see our Tower Breifing Notes on Tied In Towers.

Strength In Design

When the Alto HD Ladderspan Tower was first designed, the concept was simple - to create the best possible product to keep a person who was working at height, safe.

Every aspect of the tower was carefully considered and designed to ensure the Alto HD Tower would be strong enough to cope with the demands of everyday life on a construction site.

The unique design characteristics found on the Alto products mean that for almost 40 years, they are still the best-in-class.

FEATURES

3mm Thick Tube

The use of durable 3mm thick aluminium tube means wear & tear damage is dramatically reduced. It is 4 times more resistant to denting and crushing than the lightweight tower alternatives.

FEATURES

Scaffold Compatible

The ALTO Heavy Duty Tower - like the rest of the ALTO Access range - is manufactured using 48mm diameter tube, the same diameter as traditional steel scaffolding. This means adaptations and tying in is very easy because you can use standard tube & fittings which you cannot with a lightweight system.

FEATURES

Fully Welded Joints

Every welded joint on the ALTO Heavy Duty Tower is fully welded around the tube. This means fractured welds are a thing of the past and make the tower a much more rigid structure with joints 5 times stronger in tension & 13 times stronger in bending.

FEATURES

Non-Jamming Head Fittings

The ALTO conical head fittings prevent frames from jamming when dismantling towers so hammer damage is totally eliminated. An additional benefit of the head fittings is the frames automatically lock together during assembly, eliminating the requirement for flimsy, awkward spring clips that can be lost or damaged and render the tower unusable.

FEATURES

2500kg Load Capacity

The ALTO Heavy Duty Tower has a load capacity of 2,500 kg (2.5t) per mobile tower (3,000 kg if using base jacks) compared to between 650 - 950 Kg maximum for lightweight competitor products - reducing health & safety risks whilst increasing the range of applications available.

- Configurations -

The Alto Heavy Duty tower is available in a range of configurations to suit any situation.

Build Method.

There are 2 different build methods available for the Alto HD Ladderspan tower. The traditional Through The Trap (3T) method, and the Advance Guardrail (AGR) method.
