Limit Switches
Types of Limit Switches
There are two types of limit switches, which are
found in various locations throughout the machine:
mechanical-type
operational
or
safety
switches
and magnetic
proximity
switches. As in aircraft,
which features redundant safety systems, each
mechanical safety switch is backed up with an
independently functioning proximity switch.
The mechanical-type
operational
or
safety
switches are used to sense a positive displacement
or movement of the limit switch actuator, or
arm, as the machine moves through its range of
operational functions. Included in this group are
envelope limit switches, which sense the extended
length and angle of the boom, position of the axles
and rotational position of the turntable.
For example, when the 53° operational switch is
activated by achieving a 53° boom angle, the boom
may then be extended beyond 75 feet (22.9 m).
Another example is the drive enable limit switch,
which disables the drive function anytime the boom
is rotated past the rear axles, indicated by the
'square' end of the drive chassis.
In some cases, the engine will be stopped if safety
parameters are exceeded.
Magnetic
proximity
switches are used to sense
very specific positions of a part of the machine in
relation to the remainder of the machine. Proximity
switches must be correctly aligned for the machine
functions to operate. Proximity switches are found
at the front and rear axle, the turntable and several
locations on the boom.
