What Should You Look for in a One-Man Access Tower?

When Working at Height, Quality and Safety Are Non-Negotiable

Not all access towers perform the same  — even when they meet the same regulatory benchmarks. This guide outlines the engineering details and safety-critical features that define a high-performance aluminium access tower and provides a framework for evaluating product options on the market.

Key Factors in Choosing an Aluminium Access Tower

A professional-grade aluminium tower should not only comply with BS EN 1004-1:2020 but also demonstrate excellence in design build quality, usability, and safety. Consider the following:

• Safe Working Load (SWL)
  Higher load ratings per platform increase productivity and reduce strain on components. A robust tower will provide confidence when working with tools and materials.
• Auto-Latching Frames
  Frames that automatically engage during assembly minimise the risk of misalignment or loosening over time. This design also simplifies inspection routines.

• Brace Frames & Quick Latches
  Welded brace panels outperform bolted or crimped alternatives under load, while one-handed latch operation supports safe assembly using the 3T method.
• Rung & Tube Construction
  Welded rungs and 2.0mm extruded aluminium frames offer superior strength compared to thinner, seam-welded tubing. This reduces deformation and wear in demanding environments.
• Stability & Captive Components
  Integrated base trolleys and auto-latching stabiliser legs improve mobility and on-site stability. Captive components reduce the risk of missing parts and increase compliance with safe-use protocols.

Why These Features Matter

Maximum Safe Working Load (SWL)

A higher SWL per platform means the tower can support more weight safely. Towers with a low SWL may compromise stability and safety, especially when loaded with tools and materials, or carrying out demanding tasks.

Auto-Latching Frames 

Frames that automatically lock together reduce assembly errors and eliminate the risk of sections becoming loose over time. Unlike manual locks that can be forgotten, auto-latching systems ensure structural integrity.

Brace Frames and One-Handed Latches

Fully welded brace frames provide superior strength compared to crimped or bolted braces, which may loosen under stress. One-handed latch operation simplifies setup and dismantling, making it easier to use the 3T method and reducing the chance of improper assembly.

Rung Connections and Frame Construction

Welded rungs provide a secure and long-lasting connection, unlike cast joints, which may crack under load. Additionally, towers made from fully extruded 2.0mm aluminium offer greater durability compared to seam-welded 1.5mm tubing, which is considerably weaker.

Base Stability and Captive Components

A one-piece base trolley enhances mobility without compromising stability. Auto-latching captive legs prevent movement during use, reducing the risk of collapse.

How Alto Towers Are Built Differently

At Alto, we design our towers with a focus on long-term performance and user safety. The Alto Mini Tower features:

• Fully welded frame construction

• Auto-latching frame connections and captive legs

• 2.0mm extruded aluminium base and uprights

• 125mm heavy-duty castors with lock brakes

• One-piece folding toeboards and quick-latch panels

Our towers are engineered and manufactured in the UK to strict quality control standards. Many Alto towers remain in regular use over 20 years after installation — a testament to durability through design.
