OSHA-Compliant Mobile Fall Protection for Tank Trucks, Railcars & Hoppers.
Porta-Rack by The OIS Group delivers rugged portable truck and railcar access platforms that give your operators safe elevated access wherever trucks and railcars are parked — without the cost and rigidity of permanent loading racks.
Why Facilities Choose Portable Truck and Railcar Access Platforms from Porta-Rack
Porta-Rack units give you the safety and control of a loading rack with the flexibility of a mobile platform. Use a single unit across multiple lanes, truck types, and railcars while staying aligned with OSHA fall protection guidelines.
OSHA-Focused Fall Prevention
3-rail safety cages, handrails, and non-slip serrated grating help operators work at height without cumbersome harness lines or temporary solutions.
Adjustable Height Range
High-reach and mid-reach models cover common tanker, hopper, and railcar heights. One platform can service multiple fleets without costly civil work.
Truly Mobile & Towable
Foam-filled tires, tight turning radius, tow-bar hitch, and optional fork pockets let you position Porta-Rack units exactly where work is happening.
Built for Harsh Environments
Marine-grade aluminum and hot-dipped galvanized steel stand up to chemicals, weather, and heavy use in terminals, plants, and rail yards.
Porta-Rack Model Lineup
Whether you’re accessing the top of a tall crude tanker, a food-grade trailer, or a hopper railcar, Porta-Rack has a mobile platform configuration engineered for your operation.
High Reach
MLP-16 High Reach Mobile Loading Platform
Adjustable high-reach model for tall tank trucks and railcars, with extended 3-rail safety cage and serrated stair treads for confident footing in all weather.
Mid Reach
MLP-14 Mid-Reach Truck & Railcar Platform
Versatile mid-reach configuration covering common working heights for tank trucks and hoppers, delivering OSHA-minded fall protection without a permanent rack.
Side-Load

Compact side-entry platform for applications where operators need to approach from the side of the vehicle or when space is limited in the loading lane.
Tow & Fork Pockets
Side-Load PTA with Hitch & Fork Pockets
