NOTICE
Maximum climbing ability or gradeability is suitable
for machines with platform retracted.
1323RD gradeablity: 50% (26.6°)
1623RD gradeability: 40% (22°)
Gradeability means the maximum allowable tilt angle
of the machine when it is on solid ground and the
platform is only capable of carrying one person. As
the weight of the machine’s platform increases, the
machine’s climbing capacity reduces.
