Vehicle Fixation – Hook Fixation

Vehicle Fixation – Hook Fixation

Main Principle

The hook fixation is usable for standard passenger cars up to 2.5 t. To fix the vehicle with hooks two fixation rods are attached to the vehicle front and to the vehicle rear each. The rods are clamped to sticking anchors or sliding anchors and thus are connected to the floor of the testing room.

The hook fixation is available in three different variants:

  • with transverse rod QST
  • with tractive rod ZST
  • with rod for trailer coupling AST

Fixation Rods

Both the transverse rod and the tractive rod have a hook, the rod for trailer coupling has a docking unit. With few moves the hook is hooked into the towing lug, the docking unit is attached to the trailer coupling.

The diagonal rod DST is tightly connected to the first rod and serves as lateral stabilisation.

The whole process of mounting the hook fixation is described along with photos on a separate page.

The transverse rod (QST) runs transversely (90°) to the vehicle’s longitudinal axle. Best if there is no space behind or in front of the vehicle.

The tractive rod (ZST) is attached parallely to the vehicle’s longitudinal axle. The tractive rod absorbs longitudinal forces best.

You can use the rod for trailer coupling (AST) to fix the vehicle rear. A docking unit is attached to the trailer coupling and secured by a locking bolt.

The diagonal rod (DST) builds up the fixation triangle together with one of the rods QST, ZST or AST. A push-fit coupling safely connects both rods with each other.
