ALTO BS 1139-6 Configurations

Built for everyone...and everything!

Alto HD towers are the ultimate industrial aluminium mobile access tower on the market today. The most robust form of non-powered mobile access equipment available, only Alto HD has the inherent strength to properly deliver BS 1139-6 solutions without compromise.

Linked towers, cantilevers, façade runs – whatever your needs, Alto HD has the solution without resorting to non-standard strengthening components or exceeding Safe Working Load limits. The only tower on the UK market offering full compatibility with scaffolding - Alto HD is the versatile choice. The Alto HD Tower range is the pinnacle of safe, strong, sturdy working-at-height access.

Strength In Design

At the extremes of performance, Alto HD comes into its own. With loading capacities measured in multiples of those of any competitor, Alto HD is the only choice for advanced tower applications built under the BS 1139-6 standard.

The only genuinely fully class 3 tower system on the market and capable of class 4 loadings in many applications, Alto HD is the height of safety.

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 -

Bridge Towers

2 or more towers, linked together on the top level/s only. Used to create long working platforms. Available in both single width and double width configurations.

Cantilever Towers

A platform that projects from either the end or side at the top of a tower, providing safe working access over obstructions below that a standard tower cannot reach due to ground clearance.
