Abstract
A wheel chocking device including a longitudinally-extending base frame positioned on the driveway, a chock positioned on the base frame and movable longitudinally relative to the base frame, and a drive mechanism drivingly connected to the chock. The drive mechanism comprises a power mechanism (e.g., an electric motor) positioned outside of an outer edge of the chock path, and both the base frame and the drive mechanism are spaced from the dock face. The drive mechanism can further include a low profile transmission interconnecting the power mechanism with the chock. Preferably, the low profile transmission comprises an endless loop member (e.g., a chain). If a portion of the transmission is within the chock path, then the portion can have a height lower than a height of the chock in the lowered position.
