Troubleshooting and Repair
The BarrierGate
®
is designed to operate simply and reliably, when impacted within the
applicable NCHRP 350 criteria, even in adverse highway environments. Most operational
problems have been shown to relate to improper assembly or maintenance. Therefore it is
essential to follow the directives and specifications of the highway authority and the information
provided herein. If operational problems are encountered, begin preparing for the necessary
repair by thoroughly reviewing this Manual and all applicable location, layout, orientation, and
construction plans detailed by the highway authority.
It is critical to become familiar with BarrierGate
®
construction, assembly, maintenance, and
basic operating instructions before attempting any repairs. Follow the "BarrierGate
®
Repair
Guidelines" to help diagnose the operational problem then carry out the indicated inspection
and repair step. If these suggestions do not restore BarrierGate
®
operations, call Energy
Absorption Systems, Customer Service Department at (888) 323-6374.
A traffic control plan appropriate to the complexity of the repair project should be prepared,
approved by the highway authority, and understood by all parties before moving to the site for
BarrierGate
®
repair. Deploy the appropriate work zone safety devices prior to beginning the
repair and keep them present through all phases of the repair.
The internal components of the BarrierGate
®
can be inspected for necessary repairs without
lifting and removing gate halves. Access for inspection and repair can be made through one or
more Enclosure covers, Top Covers, Transition Skirts, Half Skirts, and Bulkhead Covers
(reference the Drawing Section of this Manual and Figure 5). The Enclosure covers can be
removed to gain access to the capstan drive system. The Top Covers can be removed to
provide a wide open area for inspection and a way of reaching or climbing down into the
BarrierGate
®
for repairs.
Caution:
Before attempting any repairs, the BarrierGate
®
must be blocked from
moving to avoid injuring maintenance personnel.
The Transition and Half Skirts can be removed to gain access at the extreme ends of the gate.
Some gate inspections and repairs may require the gate halves to be lifted and removed. In this
case, follow the reverse of the steps in the Product Description Manual under “Gate Assembly
Positioning”. Take special care to disconnect all necessary mechanical connections before
lifting the gates.
It may not be practical to complete some repairs in the field. Some breakdowns may require
components to be removed and replaced. Please follow the directives of the highway authority
in these instances.
