OCATD and Hybrid III Dummy Hoist
Home › OCATD and Hybrid III Dummy Hoist
The TE-650 is an electrically operated lift system designed for handling Occupant Classification ATDs (OCATD) and Anthropomorphic Test Devices (ATD). The primary use is to help loading and unloading the ATDs from vehicles being tested. This device differs from ordinary hoists and lifts because it can reach in the vehicle and support the dummy without interfering with the roof of the vehicle. The fixture has attachment features that are specifically designed for the OCATD and a bracket designed specifically for supporting Hybrid III ATDs.
The fixture consists of a base, a control arm, and handset. The control arm is the part of the fixture that supports the ATD. It travels vertically on the base and is powered by the 120VAC lift motor (TE-650); the TE-650-E will be available with a 220VAC motor. The handset has toggle switches that control the lifting motion of the fixture. The base has swivel casters and a low profile allowing the legs to fit under vehicles.
Lifting an OCATD
The pelvis cable attaches to the pelvis-lifting ring on the dummy. The knee bar is attached to the knee cables. And the retractable cable attaches to the chest-lifting ring.
Lifting a Hybrid III ATD
The lifting arm (Part Number TE-650-430) specifically designed to lift the Hybrid III ATD is sold separately. The arm support bars should be set at the correct distance apart. The bars should be placed under the armpit of the dummy. The leg plate is placed under the thigh with the chain passing between the thighs. Pull the chain taut and restrain it with a pin. It is not necessary to remove the arms.
The base is constructed of welded steel tubing. Four swivel casters give the base the required maneuverability for precise positioning of the ATD in the vehicle. The height of the legs of the base is minimized so that the front of the base will fit under the vehicle being tested. A vertical steel bar is used as the guide that the control arm travels along. A power supply box is mounted to the base and houses the power supply and solid state relays that control the lift motor and recline motor. A heavy-duty retracting power cord provides the 120VAC power to the system.
The control arm is the portion of the system that attaches to the ATD. It travels on rollers along the vertical bar and is powered by the lift motor. The end of the control arm has a pivot that facilitates the maneuvering of the ATD when loading a vehicle. The ATD attachments are on the pivoting part of the control arm. A special bracket is assembled to the control arm for supporting Hybrid III ATDs. This bracket supports the dummy under the armpits and at the thighs.
The OCATD attachments use three cable connection points that are located on each knee, the pelvis and the upper torso. The retractable cable assembly is used for precise control of the upper torso angle of the OCATD.
The handset is used to actuate the lift motor and the recline/ incline motor. There are two rocker switches for this purpose. A magnet on the back of the handset is for convenient attachment of the handset to the fixture.
The support fixture is controlled using the handset. There are two toggle switches; one controls the lift motor and the other controls the recline/incline motor. The incline/recline motor is used for controlling the angle of the upper torso on the OCATD dummy. The fixture may be used for passenger or driver side loading. Since the OCATD is primarily a passenger side device the system comes configured as such.
