Abstract
An improved safety clamp device for use with movable platforms and the like includes a body member having a safety cable receiving cradle, a lever arm having a safety cable engaging portion, the lever arm being pivotally connected to the body member and pivotally connected to an elongate bar member, and a modified bellcrank. The modified bellcrank has a first arm pivotally connected to the body member, a second arm pivotally coupled to a hoist line, and its apex pivotally connected to the elongate bar member. When the elongate bar member is in a first position relative to the body member, the safety cable engaging portion confronts but does not engage the safety cable. When the elongate bar member is in a second position relative to the body member, the safety cable engaging portion engages the safety cable thereby wedging the safety cable between the cradle and the safety cable engaging portions. The modified bellcrank and the lever arm operate cooperatively to maintain the body member and the elongate bar member in parallel relationship to the safety cable.
