Roben, Mfg., Inc. specializes in the custom engineering and fabrication of design of platforms, ladders, sliding guides and foundations for chemical, fine chemical, petrochemical, pharmaceutical, food and beverage, defense, and power-generation industries. Every project is designed to ASME Section VIII Division 1 (with optional Division 2), is National Board registered, complies with the European Pressure Equipment Directive (PED 2014/68/EU) for CE marking, and is registered under the Canadian Registration Number (CRN) system for all Canadian provinces.

What Design of Platforms, Ladders, Sliding Guides and Foundations Are

In addition to fabricating columns, Roben provides full engineering design of the auxiliary access systems and support interfaces — platforms, ladders, sliding guides (which accommodate thermal expansion of horizontal vessels), and the foundation interface (anchor bolts, base ring, bolt embedment data). The deliverable is a complete design package the client can hand to the civil engineer and the erector.

Why Design of Platforms, Ladders, Sliding Guides and Foundations Matter

Engineering integration is critical for project schedule. When the column engineer also designs the platforms, ladders, and foundation interface, the entire package is coordinated from day one — eliminating field-fit issues, missed loads, and re-design cycles. Our deliverable includes the load data the civil engineer needs to size the concrete.

Design of Platforms, Ladders, Sliding Guides and Foundations — Specifications and Capabilities

  • Platforms: Designed to AISC, OSHA 1910.23/29, with full FEA when required
  • Ladders: OSHA 1910.27, with rest platforms and ladder safety devices as needed
  • Sliding guides: For horizontal columns and vessels, designed for thermal expansion and seismic motion
  • Foundation interface: Anchor bolt pattern, base plate, base ring, grout requirements, weight and COG data
  • Codes: AISC 360, ASCE 7, OSHA, ASME VIII appendices

Certifications and Codes

  • National Board registration — R-stamp
  • PED 2014/68/EU — CE marking with Notified Body coordination
  • CRN — registered for all Canadian provinces
  • NACE MR0175 / ISO 15156 — sour-service compliance
  • AWS D1.1 / ASME Section IX — qualified welding procedures and welders

Frequently Asked Questions About Design of Platforms, Ladders, Sliding Guides and Foundations

A sliding guide allows a horizontal vessel or column to expand and contract on its supports without inducing thermal stress in the saddle or foundation. The vessel sits on a bronze, PTFE, or graphite slide pad on one saddle (the 'sliding' end); the other saddle is fixed.
Vertical reaction (operating, empty, hydrotest), base shear (wind, seismic), overturning moment, anchor bolt count and tension, anchor bolt pattern, base plate dimensions, and grout requirements. We deliver this in a foundation-loading data sheet.
Yes. We routinely design platforms, ladders, and foundation interfaces for columns and vessels supplied by other manufacturers — the design effort is independent of who fabricates the vessel.
We use STAAD.Pro for structural steel, Compress / PV Elite for the vessel skirt and base ring, and ANSYS / Solidworks Simulation for FEA on complex platform geometries.
Platform and ladder drawings (general arrangement, details, weld details, bill of materials), structural calculations (signed and sealed where required), foundation loading data sheet, anchor bolt template, and a coordinated 3D model on request.
