Functionality of the hook fixation

The hook fixation is suitable for standard passenger cars, test vehicles and prototypes up to 2.5 t. To fix the vehicle by means of hooks, two fixing rods each are attached to the front and rear of the vehicle. These are clamped in plug-in anchors or sliding anchors and are thus connected to the test stand floor.

The hook fixation is available in three variants

mit Quer-Stange QST

with cross bar QST

with pull-rod ZST

Anhängerkupplung-Stange AST | Fahrzeugfixierung | Bleyer GmbH

with trailer coupling bar AST

Fixing rods

The cross bar and the towing bar have a hook, the trailer coupling bar has a mounting head. The hook or attachment head is hooked into the towing eye or placed on the trailer coupling in a few simple steps. The diagonal bar (DST) is firmly connected to the first bar and serves as lateral stabilisation.

The transverse bar (QST) runs at right angles to the longitudinal axis of the vehicle. Ideal if no space behind or in front of the vehicle is available.

The drawbar (ZST) is mounted parallel to the longitudinal axis of the vehicle. The ZST absorbs longitudinal forces best.

The trailer coupling bar (AST) is available for fixing the rear of the vehicle. A receptacle unit is plugged onto the hitch.

The diagonal rod (DST) forms the fixing triangle together with the QST, ZST or AST. A ball lock pin connects the rods securely together.

Mounting hook fixation

The assembly of the hook fixation is shown below step by step using the cross bar QST. The system here is equipped with plug-in anchors. Sliding anchors can also be used. In practice  the set-up time per fixing triangle is about two minutes (rule of thumb: 1 minute per bar).

Drive the vehicle onto the test stand and align it, e.g. using the centring assistant. Apply the handbrake.

Position the first anchor so that the transverse rod QST runs transversely to the direction of travel of the vehicle.

Insert the cross bar into the open bar receptacle on the anchor. The bar receptacle remains open.

Hook the cross bar QST into the towing eye of the vehicle and turn the lever closed.

Close the rod holder and lock both locking clamps. These must engage perceptibly.

Close the locking lever on the first plug-in anchor. This fixes the anchor in the floor socket by clamping.

Insert one locking pin on each side of the rod holder through the holes in the QST cross rod.

Position the second anchor so that the angle between the diagonal bar DST and the direction of travel is max. 45°.

Insert the diagonal bar DST into the open bar receptacle of the second anchor, leave the anchor open.

Slide the clevis of the diagonal rod DST onto the mounting unit of the QST and secure it with the ball lock pin.

On the second anchor, close the rod holder, close the locking lever and insert the locking pins.

Now roll up the vehicle, then fix the rear axle. After that the vehicle is ready for testing.
