Loading Arm Systems

Faultless Safety Access Systems is a proud supplier of OPW loading arms. With the most complete line of loading arm systems and loading-rack equipment for today’s bulk loading and unloading requirements, OPW manufactures and engineers the most comprehensive loading arms systems in the market. These arms allow the transfer of hazardous fluids and LPG from one tank to another through a pipe system. When transferring liquids, you will need either a top or bottom loading arm system. In some instances, both may be required. Whether the application involves tank trucks, railcars, drums or totes, and the moving of petroleum products, liquefied gases, asphalt, solvents or hazardous/corrosive chemicals, OPW Engineered Systems is the preferred loading arm system choice worldwide.


A loading arm is flexible piping attached to gangways or racking that allows for the transfer of liquified materials from either railcar or tank trucks to its required destination. In short, it facilitates the arrival or departure of a variety of types of caustic liquids and solvents into their respective storage destinations. Each loading arm is customizable for a variety of desired features ensuring maximal efficiency is achieved and users are kept safe.

Standard Line Loading Arms

Standard Line loading arms are the most common type. These arms are pre-engineered and are our top sellers when customization is not required.

Top Loading Arms

Top Loading arms are used when greater horizontal range is required for accessing top loading railcars and trucks. Trucks of varying heights also benefit from this type of loading arm as it also provides sufficient vertical movement and drop-pipe lengths. Top loading arms can also be used for tight-fill, vapour recovery, marine and other applications when used with specially designed and engineered components, such as vapour plates, tapered hatch plugs, and inflatable hatch seals. In short, a properly designed top loading system can provide the access and movability that your users require, whilst still ensuring their full protection and safety.

Bottom Loading Arms

Bottom Loading Arm Systems are used when loading and off-loading of petroleum products, liquified gases, solvents and chemicals are performed on the ground.

  • Improved safety since operator remains on the ground during loading/unloading
  • Quicker connections reduce overall loading/unloading time
  • Bottom loading systems create less turbulence in the tank, reducing the danger of generating static electricity.
  • Bottom loading reduces vapours and the system can be adapted to also recover displaced vapours
  • Tanks can be filled faster and several compartments can be loaded simultaneously
  • Bottom-loading islands are simpler and cheaper to build than top-loading racks
