6140H 2-POST LIFT
◆
If the moving part exceed its travel distance, on
the upper part of the command post there is
one limit switch and is usually set working by
the “actuator”
(Fig. 14)
on the command side
carriage.
◆
In case of total breakdown of the limit switches,
the carriage will stop a few millimeter higher.
Because the hydraulic cylinders come to end
stroke, will cause the maximum pressure valve
(on hydraulic unit) to trip.
3.6 RISKS OF PERSONS
This paragraph illustrates risks to which the
operator, maintenance worker, or any person near
the operating area of the lift may be exposed in the
case of impeccable use of equipment.
3.6.1 RISK OF CRUSHING (OPEARATOR)
Possible if the operator controlling the lift is not in
the specified position at the command panel. When
the platform and the vehicle are descending, the
operator must never be partly or completely
underneath the moving structure. During this phase,
the operator must remain in the command zone.
(Fig. 18)
Fig. 18
3.6.2 RISK OF CRUSHING (PERSONNEL)
When the platform and the vehicle are descending,
personnel are prohibited from entering the area
beneath the moving parts of the lift.
(Fig. 19)
The lift
operator must not start the maneuver until it has
been clearly established that there are no persons in
potentially dangerous positions.

3.6.3 RISK OF IMPACT
Caused by the parts of the lift or the vehicle that are
positioned at head height. When, due to operational
reasons, the lift is immobilized at relatively low
elevations (less than 1.75m from the ground)
personnel must be careful to avoid impact with parts
of the machine not marked with special hazard
coloring.

3.6.4 RISK DUE TO VEHICLE MOVEMENT
Movement may be caused during operations, which
involve force sufficient to move the vehicle.
(Fig. 21)
If the vehicle is of considerable dimensions or
weight, movement may lead to overload or
unbalancing. All measures must be taking to avoid
such an occurrence.
