Loading arms
Bottom loading
                   
  OPW BOTTOM LOADING ARMS —
Some of the benefits bottom loading systems
provide over top loading:

•The operator of the loading arm stays on
  the ground and not atop a vehicle, where
  falls are a common threat.
•Bottom load systems create less turbulence
  in the tank, reducing the danger of
  generating static electricity.
•Bottom loading island are generally simpler
  and cheaper to build than top loading
  racks.

Top loading
             
  OPW TOP LOADING ARMS —
Some benefits of top loading:
•An efficient means of loading and unloading
  railcars and trucks in many situations.
•Properly designed, the top loading system
  has sufficient horizontal reach to access the
  farthest compartment without re-spotting
  the vehicle.
•Sufficient vertical movement and drop-pipe
  lengths to service vehicles of varying
  heights is another necessity with a top
  load system.
      Design tool  
               
  OPW MODEL E-32-F ONE ARM/FIXED REACH —
Top loader.
•Primarily used to load and unload railcars
  through open domes in installations where
  the cars can be accurately spotted.
•Includes valve, torsion spring balance,
  ductile iron inlet swivel, aluminum drop
  swivel and tube, remote control.
•Can also be used for tank truck installations,
  where some allowance for 'mis-spotting' is
  possible and increases as the diameter of
  the hatch opening increases.
•Valves can be located inboard or outboard
  to facilitate loading.
•Adaptable to tight-fill or closed-system
  loading when equipped with additional
  swivel planes of rotation and/or drop hose
  along with the required outboard coupling,
  union or fitting.
•Available in 2", 3" and 4". 2" version has
  threaded inlet connection.
•Available in steel, stainless steel, aluminum
  and specialty alloys.

  OPW MODEL C-32-RF SCISSOR STYLE —
Top loader.
•Long range, scissors-style assembly,
  commonly used to handle high flow rates
  and withstand rough usage in tank truck
  loading applications.

  flanged inlet (except 2" version; threaded
  inlet), remote control, ductile iron inlet
  swivel, loading valve, vacuum breaker,

  where the railcars are frequently 'mis-
  spotted' .
•Designed specifically for applications where
  a variable operating range is required. The
  secondary arm rotates  360° in the
  horizontal plane, providing a spotting
  allowance of up to twice its length .
•Adaptable to tight-fill or closed-system
  loading when equipped with additional
  swivel planes of rotation and/or drop hose
  along with the required outboard coupling,
  union or fitting.
