Innovative, Low Cost Hydraulic Spreader with Portable Compressed Gas Power and Manual Override

KaZaK, assisted by the University of Massachusetts - Lowell, proposes to develop and produce an innovative, low cost hydraulic spreader with compressed gas cartridge power source and optional manual override. Features include low weight, portability, quick-load high energy density compressed gas cartridge, fuel flexibility, and multiple quick-change extraction tool attachments. Additionally, a manual override mode is available as a failsafe, allowing the tool to be manually powered by the operator via hand cranking as a backup. The motivation for this portable extrication tool concept, referred to as KAGAK (KaZaK Advanced Gas Actuated Klaw), is driven by the current need to enhance operational efficiency of airborne Pararescue jumpers at a remote extraction site. Currently, rescue personnel utilize a Halligan bar to slowly and inefficiently pry structures apart during the extrication process. Alternatively, KaZaK's handheld tool will provide quick and powerful automated spreading / shearing of the structure through the combination of combustible gas and hydraulics. KaZaK and UMass Lowell will combine novel lightweight composite material approaches along with innovative mechanical systems design to optimize form, fit, and functionality of the spreader. KaZaK has considerable experience in novel device design and packaging, and has demonstrated 60% weight savings is several similar system designs.
