LOWELL, Ark. — Fleets that utilize liftgates know the speed of a liftgate is dependent on the liftgate batteries’ state of charge. They also know that liftgates that operate faster equals a faster rate of delivery. Purkeys has developed a new product to help fleets keep liftgate batteries at a good state of charge so that deliveries can be made efficiently.

The Solar Bolt, Purkeys’ patent-pending solar charging system, helps increase charging opportunities for liftgate batteries. This technology converts energy from the sun in order to charge the liftgate batteries.

According to Purkeys’ Sales and Service Engineer Larry Rambeaux, the Solar Bolt ensures liftgate batteries get the optimum charging time because it charges when the truck is both on and off.

“If other charging systems are on, the Solar Bolt will still raise the voltage to the liftgate batteries to reduce the electrical load on the tractor,” Larry said.


For more than 25 years, Purkeys has delivered innovative, cost-effective solutions for the electrical needs of heavy-duty fleets. They look at the electrical system as a whole, then strategically work to achieve the maximum return on investment while reducing maintenance costs and equipment usage. Their level of expertise has garnered more than 10 U.S. patents and attracted the attention of fleets, OEMs and other industry leaders throughout North America.
