Abstract:

A unique variable cable hoisting system utilizing a deadline load indicating apparatus in which the end terminus of the deadline is releasably anchored to a snubbing drum of the load indicating apparatus by quickly releasable hinge members which serve to restrain the end terminus against lateral movements and also to provide an abutment for engaging an abutment on the cable end terminus for opposing its axial movement under load forces and anchoring it to the snubbing drum of the deadline load indicating apparatus, when the cable system is being operatively utilized as a single fastline system. The quickly releasable feature concept, however, permits the terminus end of the deadline to be quickly detached from the snubbing drum and attached to a main hoisting drum as a second fastline to provide a double fastline hoisting system having the capability of doubling the hoisting speed.
