Maintenance
Periodic and thorough maintenance is essential for dependable and proper BarrierGate
®
operation. Take the time to review the product limitations, assembly cautions, and maintenance
instructions before performing any necessary work.
The time interval between maintenance inspections depends a great deal upon particular site
conditions. It is recommended the BarrierGate
®
be inspected once a month until it is determined
less frequent inspections will be adequate. Maintenance decisions are made by the highway
authority.
Drive-By Inspection
A slow drive-by visual inspection of the BarrierGate
®
can often spot damage which requires
maintenance. Some special inspection considerations are:
1.
Are the sides of the Gate Assemblies and steel enclosures straight and aligned
properly? If the sides are not straight or aligned then there is likely structural damage
from a vehicle impact. A walk-up inspection is required (See Walk-Up Inspection
Section).
2.
Are the Bulkhead Assemblies completely closed and locked? If there is any visible gap
between the Bulkheads then the System is not properly closed and latched. A walk-up
inspection is required.
3.
Is there an accumulation of dirt, debris, ice or snow around the BarrierGate
®
? Clean
Guide Rail and Track Sections are critical for proper BarrierGate
®
operation. If dirt and
debris is present, maintenance and cleaning is required.
4.
Are the covers on the manual drive access fully closed? If not, a walk-up inspection
should be made to further investigate.
Walk-Up Inspection
If the drive-by visual inspection indicates maintenance is required then a walk-up inspection is
necessary. Some of the most common maintenance concerns and their corresponding repair
techniques are:
Pin and Hook Section Gate Assemblies
1. Inspect the Debris Skirt for tears. Replace as necessary.
2. Inspect for and replace any bent and or damaged Side Panels, Top Covers, Transitions,
etc.
3. Lubricate all Bulkhead Assembly grease fittings every 6 months, or 750 cycles,
whichever comes first (See Figure 4).
4. Inspect and repaint any scratched painted surfaces.
