Abstract: The device provides an indication of the tension in a rope or cable and includes a rigid frame mounting first and second guide pulleys at opposite ends in tandem relationship. A central pulley is provided in the frame and the rope or cable is passed under the first guide pulley, over the central pulley and thence under the second guide pulley. The entrance and exit angle of the rope or cable over the central pulley is an angle less than 180.degree. so that when a tension is placed on the rope, a downward force is exerted on the central pulley which force in turn is measured by a load cell to provide an indication of the tension in the rope. A manually operable locking and releasing structure cooperates with the mounting means for the first and second guide pulleys in such a manner as to enable simple manual removal of the guide pulleys from the frame so that the rope or cable can be positioned in the device without having access to the ends of the rope.

Abstract: A mandrel is provided with a lifting eye at its upper end for coupling to a hoist and diametrically opposite extending lifting lugs at its lower end. A socket member having a diametrically elongated bore passing completely through the socket member is arranged to be secured in the top surface of a weight to be lifted with the top surface of the socket flush with the top surface of the weight. The socket includes a transverse channel on its bottom end extending at right angles to the diametric elongation of the socket bore. The mandrel can be lowered through the bore with the lugs passing through the diametrically opposite elongated portions and thence rotated 90.degree. after the lugs clear the bottom of the socket, the lugs then being received in the transverse channel. Springs serve to bias the mandrel and lugs upwardly relative to the socket to assure proper seating.
