The Z 1500/2000 is available with two cylinder configurations: MA and DA, denoting the following:
Cyl. config.
MA
DA
A double acting cylinder uses hydraulic pressure for both extension and compression. A single acting cyl-
inder, on the other hand, uses hydraulic pressure only in one direction and uses an outside force (gravity)
in the other direction. Double acting tilt cylinders allow for more consistent operational speeds over a wide
temperature range which is especially useful when opening and closing the platform against the box body in
colder climate.
1.1.4 Auto tilt
A tail lift equipped with auto tilt functionality automatically tilts the platform down when the platform reaches
the ground and then tilts is back up to horizontal without any additional input from the user other than keep-
ing the lower/raise button pressed throughtout the motion. The Z 1500/2000 can be equipped with two types
of electrical auto tilt systems, one based on a digital auto tilt sensor and one based on a analog sensor. It
can also be without any auto tilt functionality. Whether the tail lift is equipped with auto tilt functionality or
not cannot be determined by reading the information on the type sign. Instead the type and number of sen-
sors installed on the platform should be checked.
