NOTICE
Maximum climbing ability is suitable for machines
with platform retracted.
Maximum Slope:
GTJZ0612E: 25% (14°)
GTJZ0812E: 25% (14°)
GTJZ1012E: 25% (14°)
GTJZ1212E: 25% (14°)
Climbing capacity 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.
