The bottom roller is used to support the mechanical weight. The bottom roller is also known as the lower roller or track roller. -
Function:
-
The main function of the bottom roller is to support the weight of the crane, transfer the weight of the locomotive set and the lifted goods to the ground, and roll on the track shoes.
-
The bottom roller also helps limit the track shoes and prevent lateral slippage. When the machine turns, the bottom roller forces the track to slip on the ground.
