  • Self-tensioning tie down system
    Patent number: 7972099
    Abstract: A self-tensioning tie down assembly and safety system for tightening the retaining straps securing cargo on a carrier. Retaining straps are connected to winches connected to the carrier. A ratchet system is used to tighten the winch. A two bar torque linkage has a ratchet arm connectable to the ratchet wheel of the winch via a socket and has a connector arm connected to an actuator. The actuator is connected to a pneumatic/electrical circuit and provides reciprocating linear motion thereby actuating the torque linkage. The torque linkage may be set in a tightening or loosening position. The required tension level of the retaining strap is pre-set. Pressure within the circuit drives the actuator thereby actuating the torque linkage which tightens the strap on the winch until the tension level is reached. Signals are sent to a display panel to indicate when a strap is loose.

  • Self-tensioning tie down assembly
    Patent number: 7857560
    Abstract: A self-tensioning tie down assembly (2) for tightening retaining straps (70) about winches (64) securing cargo (71) on a carrier (73). The assembly (2) has an actuator (15) connected to a pneumatic circuit (61) and providing reciprocating linear motion to a torque linkage (60) connected to the winch (64). The torque linkage (60) has a wrap spring clutch (17) connectable to the ratchet wheel (7) of the winch (64) and a connector arm (11) connected to the actuator (15). The torque linkage (60) transmits the linear motion to the winch (64) as a corresponding rotational motion. The required tension level of the retaining strap (70) is pre-set. Pressure within the circuit (61) drives the actuator (15) thereby actuating the torque linkage (60) which tightens the strap (70) on the winch (64) until the tension level is reached.
