Patent attributes
An apparatus (1) for reliably blocking a vehicle (2) at a loading dock (3) includes a telescopic arm (4) that at one end (4A) is supported so as to be stationary but is pivotal about two axes (P1, P2) and that at the opposite end (4B) is provided with an engagement element (5) for effecting a blocking connection between the vehicle and the area of a loading dock. At the same time as the stationary end maybe provided at a safe position where it is practically completely out of the way when it comes to e.g. snow clearance and risk of being run into, the capability of pivotal movement and the telescopic design of the arm makes it possible to easily maneuver the engagement element into a blocking or restraining engagement from the outside of the vehicle.
