Abstract
A mobile device for forcing a highway post into the ground in the vertical position, especially where the highway post is flexible and made of fiberglass, which involves a vertical column spaced from and supported by the mobile device, guide means mounted on the vertical column to hold a reflective highway post in a vertical position while the post is forced into the ground by repetitive blows from a hydraulically driven hammer and means for moving the vertical column and the guide means upwards in a vertical direction when the post has been forced a sufficient distance into the ground.
Claims8
A device for forcing a flexible reflective highway post into the ground in a vertical position comprising:
- a mobile platform,
- a vertical column spaced from and supported by said mobile platform,
- guide means slidably mounted on said vertical column and adapted to hold a flexible reflective highway post in a vertical position and adapted to prevent said highway post from bending and flexing while said post is forced into the ground, means for mounting said guide means out of said ground at all times,
- means mounted on said guide means for forcing said post into the ground, and
- means for moving said vertical column in a vertical direction and including means for raising both said vertical column and said guide means when said reflective highway post has been forced a sufficient distance into the ground.
