Top Loading Overview
Top loading railcars and trucks continue to provide an
efficient and cost-effective method to load and unload in
many situations.
A loading system should have sufficient horizontal range
to reach the farthest compartment without re-spotting the
vehicle. Sufficient vertical movement and drop-pipe lengths
for servicing vehicles of varying heights are also necessary.
A properly designed top-loading system can achieve this
requirement. Top loading can also be used for tight-fill
and vapor-recovery applications when used with specially
designed and engineered components, such as vapor
plates, tapered hatch plugs and inflatable hatch seals.
TOP LOADING
The 7300 IHS Inflatable Hatch Seal is a device for sealing
different hatch openings on tank trucks and railcars to
prevent the release of vapors into the atmosphere.
Special top loading designs can be supplied with a wide
range of valves, fittings and instrumentation equipment.
