Secure the machine properly so it cannot slip, slide,
roll, tip over or fall, or cause the transport vehicle to tip
over under transport conditions. Use anti-slip bases and
linings, load-securing straps and chains, clamping
beams, protective paddings, nets, edge protectors, etc.
as needed to properly secure the load. Consider all pos-
sible transport conditions such as: heavy braking, eva-
sive maneuvers, and uneven or rough roadways. Make
sure the load does not exceed the authorized maximum
height.
