For most loading or unloading operations, safe access is a constant priority. However, traditional stairways or integrated ladders often fail to accommodate the evolving demands of most businesses. Looking for a secure, reliable, and adaptable way to access the tops of your equipment? The answer lies in articulating stairs. In this blog post, we’ll break down the three types of articulating stairs that Northern Platforms offers. Keep reading to learn more! 

Self-Adjusting Stair Gangways (SAS)

As the #1 selling gangway in North America, SafeRacks’s self-adjusting stair gangway (SAS) is the gold standard for safe vehicle access. These innovative systems feature stair treads that articulate and self-level automatically, easily accommodating different vehicle heights.

Here are some key details about the SAS gangway:

• Suitable for trucks, railcars, and isotainers.
• Adjusts to different vehicle heights with an 85-degree working range.
• Available widths include 24”, 36”, 48”, 60”, and 72”.
• Stairs can reach up to 101.5” in length.
• Made from aluminum and includes stainless steel hardware.
• Are compatible with SafeRack’s safety cages for complete fall protection

Flat Ramp Telescoping Gangways (FRT)

Flat ramp telescoping gangways offer specialized solutions for operations requiring extended reach capabilities, which can be particularly useful in railcar loading applications. The FRT design features a slip-resistant surface that eliminates dangerous gaps between loading platforms and railcar surfaces. This 21-inch telescoping extension accommodates various railcar configurations while maintaining safe footing for operators.

Important features of the FRT gangway include:

• Specifically designed for railcar loading operations.
• Widths from 24” to 72” available.
• Available materials include aluminum, stainless steel, and galvanized steel.
• 37” to 89” range reach, with possible extensions to eliminate gaps.
• Can hold up to 500lbs, with a handrail weight rating of 200lbs.
• Top handrails can telescope in applications without a safety cage.

Simple Flat Ramp Gangways

If you are looking for an entry-level gangway, a simple flat ramp gangway is the right option for you. While this model does not offer the same articulating or telescoping features as the other options on this list, this cost-effective solution still has benefits. For example, it is more cost-effective than other articulating stairs, making it an excellent choice for small operations with limited budgets. Additionally, the straightforward flat ramp design features a slip-resistant walking surface and easy-to-use features, making it a popular choice for hopper car or truck applications where minimal height variation exists.

Here are some key features of the SFR gangway:

• Suitable for both trucks and railcars, with specific advantages for hopper cars.
• Features rubber bumps and machine-quality pivot points.
• Widths ranging from 24’ to 72”, with a reach range of 36” to 88”
• Available in aluminum, stainless steel, and galvanized steel.
• Load capacity of 500lbs, with a handrail weight rating of 200lbs.
