Hurst Develops Line of Self-Contained Hydraulic Rescue Tools

Hurst Jaws of Life has introduced eDRAULIC, a line of hydraulic rescue tools that can be powered by either an onboard 25.2-volt lithium ion battery or a 110-volt shore line.

The new series includes the SP 300E spreader, which has a 24-inch opening with up to 25,000 pounds of spreading force and weighs 44 pounds; the S 700E, a cutter with a 7.1-inch opening that weighs 54 pounds; the smaller S 311E cutter, which has a 6-inch opening and weighs 38-1/2 pounds; and the R 411E, a single-stage ram with a lifting force of more than 23,000 pounds that weighs 37 pounds.

“These tools offer the best strength-to-weight ratio of anything on the market today,” said William Simmons, general manager of Hurst Jaws of Life. “The key is to have tools that have the power of standard hydraulic systems on an independent platform.”

By developing a series of tools with self-contained hydraulic systems, each with its own reservoir, bladder and pump, Simmons said Hurst is able to optimize them for maximum performance while saving space and weight.

“Self-contained tools take up about half the space on a fire apparatus compared to traditional tools with power plants and hydraulic hoses,” he said. “By eliminating that power unit and the hoses, we also are able to reduce the weight carried on the apparatus.”

The SP 300E spreader has been redesigned to operate in battery mode in the most challenging environments, Simmons noted. He said the new spreader, as well as the other tools in the eDRAULIC line, can run off a battery for approximately 30 minutes before the battery would have to be switched or the tool plugged into a power cord for continuous operation.

The SP 300E has diamond tips for improved vehicle extrication, very flat tips to penetrate the narrowest gaps, and a special diamond-type surface finish to provide a sure grip.

The S 700E cutters offer improved curved blades to enhance the pull effect, optimized for current and upcoming vehicles that are expected to have stronger and wider car posts. The smaller version cutter, the S 311E, was designed with sophisticated blade geometry, Simmons said, meaning the tool is optimized for vehicle extrication.

The R 411E ram, the first such ram tool without hoses, offers compact strength, Simmons said. The claws at both ends can be rotated 360 degrees, enabling a firefighter to apply the ram effectively in any rescue situation. The optimal extended length of the ram is 47.2 inches.

“Eliminating the power units and hydraulic hoses lets firefighters get the job done as quickly, safely and efficiently as possible,” Simmons said.
