Abstract

One embodiment of the present invention relates to an assisted braking belay system (100) with a housing (120), camming mechanism (140), and clutch mechanism (160). The housing (120) may include a substantially enclosed rope channel (128) through which a rope (110) may extend to the climber. The camming mechanism (140) is moveably coupled to the housing (120) and configured to automatically engage a camming surface (142) upon the rope (110) across the rope channel (128) if the rope (110) translates through the channel (128) at a particular acceleration rate. The clutch mechanism (160) may function as a secondary locking mechanism to engage the camming surface (142) of the camming mechanism (140) upon the rope (110) across the rope channel (128).
