Q. How does the roll sensor know when to activate the protective devices?
The roll sensor deploys RollTek’s protective components based on the vehicle’s angle and rate of roll. In addition to acting as the “brain” of the RollTek system, the roll sensor also acts as a “black box,” recording crash events for post-crash evaluation.
Q. Will the system work if an officer is not wearing a seat belt?
Although an unbelted passenger may be afforded some protection by the airbags, the RollTek system relies on seat belts as its core restraining device. It is important that all vehicle occupants are seated and belted at all times.
Q. How long does it take the RollTek components to deploy?
The entire process from activation to deployment takes less than ¼ of a second (.234).
Q. What fills the airbag?
Both the Inflatable Tubular Structure (ITS) ad Inflatable Head Cushion (IHC) fill with argon, a gas that is half the temperature of that used by traditional airbags. These lower temperatures mean that the airbags are made of thinner fabrics, eliminating the need for heat shields found in earlier airbags and resulting in a lighter, more compact airbag module.
Q. How much does the RollTek system cost?
The cost of the system varies by manufacturer. Please contact your truck manufacturer for more information.
Q. Will the RollTek system deploy in a frontal collision?
The RollTek system will not deploy in a collision event that does not involve a roll. The system is designed specifically to deploy only when the sensor detects an irrecoverable rollover.
Q. If my truck has been in a rollover will I need to replace the RollTek system?
For your own safety, RollTek components are designed for one use. Should your vehicle be involved in a rollover, the RollTek system will need to be replaced. Do not attempt to repair or restore any damaged components yourself.
Q. Which manufacturers offer RollTek-equipped apparatus?
Today, Pierce and KME offer chassis equipped with RollTek, and in 2005 Ferrara will debut RollTek on two chassis.
Q. Can RollTek be retrofitted into older apparatus?
While RollTek can be retrofitted into older trucks, the cost of testing and retrofitting is typically more expensive than buying a new vehicle already equipped with RollTek. If you would like more information on retrofitting, call 1-866-RollTek.
Q. How many RollTek-equipped apparatus are currently in the field?
RollTek-equipped apparatus have been available since June of 2003. Today there are hundreds of RollTek-apparatus in the field, and by this time next year that number will be in the thousands.
