Abstract

1,246,769. Automatic gripping devices for lifting girders. E. D. BUTZ. 23 March, 1970, No. 14033/70. Heading B8H. In a lifting device, Fig. 11, the grip of jaws 12, pivoted at 11 to a plate 10, is produced by the force applied to levers 15, 17 by lifting ropes 19 which also push abutments 24 into engagement with the top of the load through pinions 20 and racks 22. When the device is lowered on to the load upward movement of the abutments opens the jaws. In a second embodiment, Fig. 4, the jaws 107, 107a are connected to the vertically slidable abutment 115 by a cable 105. The jaws are automatically locked in the open position by abutments 131 and are released to close when a handle 130 is raised. Fig. 9 shows a further embodiment in which the upper ends of jaws 152, 152a overlap each other and each supports a pulley 157. The lifting rope 160 passes down and under one of the pulleys 157, up and over a rope guide 159 attached to the top of an abutment 153, as shown at 160<SP>1</SP>, down under the other pulley 157, and up as shown at 160<SP>11</SP>. An automatic latch 168 holds the jaws open until it is manually released. (For Figures see next page.)
