by operators around the lift. ◆ 2 posts, (service (Fig. 2-1) and command (Fig.
2-10) side post) built with bent steel plate. The
base is welded to a drilled plate to be anchored
to the floor. The hydraulic power unit (Fig. 2-7)
are attached to the command post. Inside each
post are the moving parts to lift the vehicles.

◆ The column set on the base.

1.2 MOVING UNITS

Each unit consists of:

◆ Both carriage (Fig. 2-3 and Fig. 2-6) built with

welded steel plate. It joints by chain (Fig. 2-2)
and the cable (Fig. 2-9), and at the bottom to

and from beginning to end as it contains important
information regarding the risks that the operator and
the maintenance fitter may be exposed to in the
eventuality that the lift is used incorrectly.

The following text contains clear explanations

regarding certain situations of risk or danger that
may arise during the operation or maintenance of
the lift, the safety devices installed and the correct
use of such systems, residual risks and operative
procedures to use (general and specific precautions
to eliminate potential hazards).

5.1.1 UP PUSH BUTTON carriages are totally lowered, the automatic arm-
blocking device opens and lets the carriages rotate.
If pressed, it activates the electric motor and
mechanisms that lift the carriage.

5.1.2 LOWERING LEVER

By pressing down the lowering lever, it activates the

pressure relief valve. The oil from oil cylinder returns
to the oil tank. The carriage lowers.

5.2 OPERATING SEQUENCE

Position the lift arms in the hold points prescribed for

the vehicle, adjusting the disks to the same height.

Each time the carriages are brought down to the

ground, check the position of the disks under the
chassis of the vehicle before raising the carriages
again.
