Two-level equipment platform around a machine with stair and ladder

More than a floor around a machine

A machine platform carries the equipment, the people who run and maintain it, and everything in between – spare parts, tools, pallets and the loads of lifting and replacement. It has to be stiff enough not to resonate with rotating machinery, strong enough for impact and maintenance loads, and safe for daily access for decades.

We design platforms from the equipment data – weights, footprints, dynamic loads and maintenance access – and deliver the complete package: columns, beams, bracing, grating or plate floors, guardrails, toe boards, stairs, ladders and gates, galvanised or coated, pre-drilled and ready to bolt together around your machines.

Scope

Platforms for every machine and plant

From a single maintenance platform to multi-level equipment structures.

operating level

Machine platforms

Operating floors for machines, presses, extruders and process lines, with stairs and guardrails.

multi-level

Equipment platforms

Maintenance and inspection platforms at several levels around tall equipment.

storage · plant

Mezzanines

Storage, plant and office mezzanines with grating, plate or deck floors.

over conveyors

Catwalks & crossovers

Walkways along conveyors and crossovers over lines, pipes and walkways.

vertical access

Stair towers & ladders

Stair towers with landings and fixed ladders with safety cages to tall equipment and roofs.

safety

Guardrails & details

Guardrails, mid-rails, toe boards, self-closing gates and stair handrails.

Applications

Engineered, not just fabricated

Equipment loads from data

Static, dynamic and impact loads from the equipment supplier, plus maintenance and lay-down loads.

Vibration checked

Natural frequencies kept away from machine operating speeds; stiff connections and bracing where needed.

Access to code

Guardrails, toe boards, stairs and ladders detailed to OSHA 1910, ISO 14122 or AS 1657.

Grating that fits

Load-bearing or serrated grating, plate or composite floors sized for the span and use – see steel grating.

Install around running plant

Bolted, modular platforms assembled in short shutdown windows.

Durable finish

Hot-dip galvanising or paint systems for indoor, outdoor and corrosive environments.

Safety

Guardrails, toe boards and stairs to code

Access details are where platforms fail inspections. We detail guardrail heights, intermediate rails, toe boards, stair angles, landings and ladder cages to the standard of your market – OSHA 1910 in the United States, EN ISO 14122 for machinery in Europe and many international projects, AS 1657 in Australia – and design top rails for the specified loads.

Equipment platform around a large machine

Vibration

Stiff enough for rotating machinery

A platform that resonates with a fan, pump or compressor will crack welds and loosen bolts. From the equipment's operating speeds and unbalanced forces we check the platform's natural frequencies and keep them clear, stiffen beams, add bracing or isolate the machine where needed.

Installation

Bolted together around your running plant

Platforms are fabricated, galvanised or coated and trial-fitted in our factory, marked by piece and shipped with bolts and erection drawings – so they can be assembled in a short shutdown, often without hot work on site.

Reference

Typical design loads and floor types

Indicative values for early planning – the project code and equipment data govern.

Floor types
Floor	Best for	Notes
Bar grating	Plant platforms, outdoor, wash-down areas	Light, self-cleaning, drains water and spills
Serrated grating	Wet, oily or sloping areas	Improved slip resistance
Chequer plate	Under equipment, where nothing may fall through	Heavier; needs drainage
Composite deck	Mezzanines with heavy storage or offices	Concrete on steel deck; fire and acoustic performance

FAQ

Questions fréquentes

Which safety standard do you detail to?

The one that applies at your site: OSHA 29 CFR 1910 Subpart D in the United States, EN ISO 14122 for machinery access in Europe and many international projects, and AS 1657 in Australia and New Zealand.

How do you avoid vibration problems?

We use the machine's operating speeds and dynamic forces to check the platform's natural frequencies and keep them clear of resonance, adding stiffness, bracing or isolation where needed.

Grating or plate floor?

Grating for most plant platforms – light, self-cleaning and draining; chequer plate where nothing may fall through; composite deck for heavy storage or office mezzanines.

Can platforms be installed without stopping production?

Mostly yes. Bolted, pre-drilled platforms are assembled quickly, often in a short shutdown and without site welding.

Galvanised or painted?

Hot-dip galvanising is the durable choice for outdoor and wet areas; paint systems suit indoor platforms or colour-coded plants.
