An apparatus for reblocking the panel body of a wrecked vehicle, comprising jack pads to immobilize the vehicle relative to the ground, a main upright post at a distance from the vehicle and pivoted to the ground about a vertical axis. A number of chains are mounted to the upright post and are adapted to be anchored to the panel body. A pair of vertically acting rams pull the chains anchored to the vehicle to reblock its panel body. The mounting of these chains on the upright post is characterized in that the vector of pulling force automatically adjusts to shifts in distribution of the load sustained in operation by concurrent rotation of the upright post about its vertical pivotal axis.
