The PEG-40, made by Geomatrix, is an accelerated weight drop. It comes with trigger contacts and cables to start Geode™ multichannel recording.
The PEG-40 weight drop connects to a regular 2-inch hitch at the rear of a car (rectangular pipe; common in the US). An adapter to connect the PEG-40 to a 6-hole Pintle Hook Mount Plate is also available (see pdf and jpg). Please note that a vehicle with a permissible maximum vertical loading on the coupling point ("Stützlast") of at least 120kg is needed.

Please also note that for driving (with the PEG-40 attached) on public roads a TÜV-entry in the car license is needed.
