Since truck terminals and shipping ports see significant tractor trailer and forklift traffic, trench drain systems in terminals need to be HS20 or HS25 load rated and wide enough to capture large water flow from concrete lot.
Terminal buildings, where fork truck traffic with concentrated wheel loads are high, have lower drainage requirements. Here, 4" wide drainage systems with cast iron grates and frames are common.
Things to Consider:
- Surface Area. Trucking terminals sitting at a low point of a large surface area will require larger trench drain systems. Interiors and warehouse buildings don't require as much coverage and can get away with narrower drains.
- Strength. With forklifts and heavy trucks crossing daily, trench drains need Class E or Class F grates to hold up to traffic at trucking terminal buildings.
- Layout. Trench drains designed for simple, straight runs don't adapt to T intersections or angles. For complex layouts, trench former systems and frame-and-grate systems will save time and money by eliminating on-site fabrications.
Recommendations for Terminal / Port Drainage Systems
Polycast 700 Series (by Hubbell)
This 6" polymer concrete trench drain system is reinforced by cast iron frames and iron grating to create Class E and Class F load rating. The 700 Series' polymer concrete channel gives the system high compression resistance and makes it chemical resistant.
EN1000 Series (by MEA)
With a total width of 5.5" and a 4" interior, the EN1000 Series utilizes integral iron rails and iron grates to boost its load rating to Class E or Class F. The system offers bottom and end outlet options as well as multiple slope options for contractors who need design flexibility.
EconoDrain No. 6 Series (by MultiDrain)
The 6" former system by Multidrain Systems combines the flexibility of a frame-and-grate system with the convenience of a modular trench drain. The system's heavy duty cast iron grates and frames reinforce the concrete channel body, creating a durable system.
R-4990 Series (by NFCO)
Neenah Foundry offers heavy duty frame-and-grate systems guaranteed to withstand trucking terminals and port traffic. Grates can be bolted down for additional stability. Choose from a selection of widths to meet your flow requirements.
