Abstract: A safety clamping device for clamping onto a first rope portion and retaining a second rope portion. The clamping device comprises a clamping portion and a retaining portion. The clamping portion clamps onto the first rope portion, and comprises first and second clamping members in use hingedly coupled to one another such that the clamping portion is movable between an open configuration suitable for receiving the first rope portion and a clamping configuration suitable for clamping onto the first rope portion. The retaining portion retains the second rope portion relative to the position of the first rope portion, and is coupled to the clamping portion.

Abstract: An apparatus for suspending a log comprises a cable having at one end a knob to be hitched into a hitching body. The hitching body which is provided for this purpose with a longitudinal opening is pivoted to a swivel head between a closed position in the swivel head and a release position swiveled out of the swivel head. The swivel head has a sliding eye through which the cable is slidingly guided. With a locking device the hitching body is locked in the closed position. For actuating the locking device, an actuator is provided which is driven with a remote control. The longitudinal opening of the hitching body has an enlargement at its end facing away from the swivel pin for hitching and unhitching the cable end with the knob in the closed position. Below the enlargement a support for the hitched knob is provided. The locking device has a locking bolt which engages a notch in the hitching body .

Abstract: Streetlight poles are lifted to a vertical position for installation in a mounting hole or on a support stand by connecting the lift cable of a boom to an elongate sling that is releasably attached to the pole.

Abstract: A lifting sling and a method for making the same are disclosed. The lifting sling comprises an elongated, flexible member having a working surface, a lifting end portion for attaching to a lifting mechanism and a choker end portion. A plurality of longitudinally spaced apart gripping members are attached to the working surface of the flexible member for frictionally engaging the outer surface of a load being lifted. To make the lifting sling, the flexible member is laid on the face of a mold having cavities for forming the gripping members. Liquid casting material is introduced into the mold cavities and allowed to penetrate the surface of the flexible member for permanent bonding thereto.
