We custom bend 3/8 alloy steel to form the inside and outside track. Then we punch holes every 6 inches on the outside for the towers to lock.
Tower bases are three large and thick steel tubes welded together to help support a larger pipe for pulling. Then we add a tray to hold your hydraulic pump when not being used.
The pinchweld bases are 3 inch round instead of 2 1/2 inch. Plus the bolts that hold them in place are larger also. This really holds a vehicle in place when pulling.
We then include a extra hydraulic pump for raising and lowering the platform.
