Bottom Loading Arm
(A-Frame – AF-54)

AF-54 bottom loading A-frame arms store with the primary in a vertical position. When extended, the primary arm and drop pipe or hose create an “A” shape. Used when space overhead is available for the riser pipe, either hose or pipe can be used in the drop section to reach the connection point.

Applications & Benefits

  • The A-frame arms can be spaced horizontally on 24″ centerlines which allow multiple arms to be installed in a confined area.
  • Tight spacing allows use in applications where multiple products are loaded into trucks in the same bay (such as Petroleum Terminals).
  • Up and down rotation conforms to the API loading envelope as defined by API 1004RP.
  • Longer A-frame arms are often used in top loading and unloading on railcars; common in closed fill applications where the arm connects to a nozzle on the railcar.

Bottom Loading Arm
(BL-54)

BL-54 bottom loading arms store primary in horizontal position to either side of the riser pipe depending on the piping layout and pre-existing obstructions. These arms rotate above and below horizontal to reach the connection point on the truck. They require less overhead space than the AF-54 but require more space adjacent to the arms for storage; either hose or pipe can be used in the drop section to reach the connection point.

Applications & Benefits

  • BL-54 arms can be spaced horizontally on 18″ centerlines and vertically on 16″ centers allowing multiple arms to be installed in a confined area.
  • Tight spacing allows these arms to be used in applications where multiple products are loaded into trucks in the same bay (such as Petroleum Terminals).
  • Up and down rotation conforms to the API loading envelope as defined by API 1004RP.

Bottom Transfer Arm
(BT-377)

BT-377 bottom loading or unloading arms are low-profile and so require no overhead structure for support. Typically mounted very low to the ground, the primary arm and boom sections extend out into the loading area like an accordion. BT-377 arms are used when storage space is laterally available and no upper structure is available for support.

Applications & Benefits

  • The low mounting arrangement works very well with single product loading and unloading applications where vertical piping and support structures are not available.
  • Common applications include single product loading and unloading such as Ethanol, Bio Diesel, Crude Oil and Crude Condensate.
  • Two of these arms can be mounted in tandem on a post for servicing LPG and similar applications where product and vapor recovery arms are required.

Bottom Loading Arm
(BT-44)

BT-44 bottom loading or unloading arms are low-profile economical choice for bulk offloading and require no overhead structure for support. Typically mounted very low to the ground, the primary arm and boom sections extend out into the loading area like an accordion. BT-44 arms are used when storage space is laterally available and no upper structure is available for support.

Applications & Benefits

  • The low mounting arrangement works very well with single product loading and unloading applications where vertical piping and support structures are not available.
  • Common applications include single product loading and unloading such as Crude Oil and Crude Condensate.
