Abstract:
An abseil rescue system, allowing a user to descend on a rope, comprising:a velocity control system, comprisinga first brake and a second brake, said first brake having a front end with a plurality of grippers, said second brake having a front end with a plurality of grippers with a gap, said plurality of grippers of said first brake located in said gap of said plurality of grippers of said second brake, said first and second brakes being hingedly connected by a shaft, with said plurality of grippers thereof for gripping said rope, anda first retarder and a second retarder, said first and second retarder having front ends with pluralities of alternatingly arranged grippers with gaps, said pluralities of grippers of said first and second brakes located in said gaps of said pluralities of grippers of said first and second retarders, said first retarder having a stud, said second retarder having a blocking part for engaging with said stud to keep said first and said second retarders parallel and next to each other, said stud being movable against an elastic force of a spring for disengaging from said blocking part, said first and second retarders being hingedly connected by said shaft either, with said plurality of said grippers thereof for gripping said rope;whereby, said plurality of grippers on said first and second brakes can be operated to clamp said rope crookedly so that a velocity control can be reached due to an increased friction force, and said first and second retarders can keep grasping said rope to slow down the descending speed.
