ABSTRACT:
A device (10) that is designed to spread, crush or cut pieces of metal or other materials. The device (10) is particularly adaptable for removing material from a vehicle in which is located a trapped accident victim. The device (10) consists of a first arm assembly (12) which functions in combination with an interlocking second arm (46). The first arm assembly (12) and the second arm (46) operate with a drive-mechanism yoke (100) that pivotally attaches the lower ends (22) on the first arm assembly (12) and the second arm (46). The device also include a drive yoke (50) which includes a pair of cam pins (94,96) that traverse a cam slot (26) located on each arm. The drive yoke (50) includes a drive rod (86) connected to a linear actuating mechanism (172). When the mechanism (172) is in a retracted position, the first arm assembly (12) and the second arm (46) close, and when the mechanism (172) moves upward into a non-retracted position, the two arms open.
