Abstract: An automatic tension sensing and control system for cargo restraints comprises a load binder, a tension sensor, an actuator coupled to the load binder, and a control module. The control module receives signals from the sensor and can command the actuator to tighten or slacken the load binder. The system can also include an annunciator and an information storage and retrieval system.

Abstract: A tensioning device comprised of; a gear box containing a bevel gear assembly inside the gear box with one gear attached directly to a barrel which passes through the gear box and threaded shafts at either end of the barrel. Inside the gear box is a guide which is placed such that a drive gear and the barrel gear are engaged when assembled and a socket wrench receptacle is part of the drive gear. The threaded shafts move in and out of the barrel based on the rotation of the gear. The tensioning device uses direct gearing of the rotational motion of the drive gear to rotate the barrel causing the shafts to be linearly displaced tightening or loosening a chain, cable or strap.

Abstract: The actuating unit mounts a workpiece gripping and transporting jaw assembly and has an elongated hanger rod supporting a first mount boss. A pneumatic cylinder is arranged below the rod and secured to the boss and has a conventional piston and piston rod projecting from the cylinder. The improvement which comprises an elongated guide rod between the cylinder and hanger rod slidably positioned through the mount boss projecting forwardly thereof and at one end supporting a jaw mount assembly having a longitudinal bore. A stroke adjuster collar is secured upon the other end of the guide rod and adapted to limit forward movement of the jaw mount assembly. A rod adapter is movably positioned through the bore of the jaw mount assembly which includes a first mount flange on the forward end thereof. A jaw assembly includes a body having an annular mounting flange at one end mounted upon the first mount flange and adjustably secured thereto.
