LifeJacket Saves Lives...and Reputations
In addition to the irreversible human tragedy associated with an
elevator accident involving personal injury, such an event pres-
ents serious legal challenges that can compromise the market-
ability of a building for years.
The LifeJacket helps preserve the integrity of your safety record
AND serves as an excellent marketing tool to attract key tenants.
How Does the LifeJacket Work?
The LifeJacket is a lifesaving system
with three components:
1) An electrical sensing system that detects uncontrolled
downward movement of the plunger
2) Two (2) steel arms that close to grab a falling plunger
3) A hydraulic feedback system to monitor hydraulic pressure
Almost as important as its lifesaving function is the fact that the
LifeJacket’s safety arms will not damage the plunger. This
means that LifeJacket can be tested regularly to verify that it is
operating properly.
LifeJacket is peace of mind for you...and safety assurance for
your elevator riders.
