ALTO HD Stair Tower

Class-leading Towers

Easy Access As Standard

Manufactured using the same components as its ladderspan counterpart, the Alto Heavy Duty Stair Tower is a fully accessible mobile access tower that uses traditional flights of stairs to gain access to the work platforms, rather than the vertical ladder design.

The Alto HD Stair Tower is ideally suited for longer-term installs, or on jobs where the work platform needs to be accessed from the ground more frequently than normal.

Compatibility Within Ranges

The Alto HD Stair Tower is the only one of its kind on the market. The traditional sloping staircase integrated inside the tower means that access to the working platform is now easier and safer than a vertical ladder.

The stair design gives a much more flexible working environment as tools & materials can now be carried up through the tower by the end-user instead of requiring winches, ropes or cranes.

- Features -

Inclined Stair Access
A traditional sloping staircase integrated inside the tower means that access to the working platform is easier and safer than a vertical ladder. Tools & materials can now be carried up through the tower by the end-user instead of requiring winches, ropes or cranes.
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.
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.
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.
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.
2500 kg 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.
