Section X. FRAME ASSEMBLY
215. General
The main frame of the road roller is of all-welded construction. The main members and reinforcing braces are made of
structural steel channel. The steering roll cover and steering roll yoke head housing are constructed of heavy gage steel
sheets, electrically welded to the main frame. The structural channel cross-members reinforce the main frame and
provide mounting support for the transmission, engine, and its accessories. The operating load is distributed between the
steering and compression rolls and their axles. The road roller frame is designed to withstand high stresses and will
seldom require repair.
