MP SERIES CONE CRUSHER TECHNICAL REFERENCE MANUAL
Safety Gates
Some safety gates are designed so that opening or
closing of the gates will prevent or stop a specific
machine function in that area. Hydraulic or electric
limit interlock switches may cut off the drive or
actuator power or initiate an emergency stop mode.
For specific operation, see later sections of this
manual.
Safety gates may also be opened for maintenance
purposes when the machine has been stopped.
Follow all lockout procedures.
Cable Switches
Cables or ropes connected to the electrical switches
can be used as interlocks also. They may stop
machine function in areas where control panels
cannot be closely located but where Operators may
be working. Know the locations of E-stop pull
cords for conveyors.
0.3.1.4 Additional Warning Devices
Horns and Lights
If visual contact between work places is obstructed
or if communication is difficult, sound and/or light
signalling devices may be used before starting the
machine or a machine function. The warning
device for start-up should operate so that personnel
are given sufficient time to move to a safe distance
from the machine. It is the responsibility of the
Owner to ensure that the Crushing Plant is always
equipped with required horns and lights.
Safety Signs and Labels
Safety signs have colors to determine the degree of
hazard in particular areas. These signs must not be
removed. Temporary placement of safety signs and
danger tags should also be used on the control
panels to warn of maintenance work and lockout
situations.
Obey all warning and safety signs on the machine
and in the manual.
Safety Warning Colors
Color of safety warnings are typically safety
yellow.
0.3.1.5 Walkways, Service Platforms,
Ladders and Railings
The design of walkways, ladders and railings
follow standards and regulations for the
application. The walkways provide access to the
machine. Safe operating procedures must be
followed when on walkways. Never stand, walk or
climb in or on any area of the Crushing Plant not
designated for such activity. If an area of the
Crushing Plant must be accessed and cannot be
reached by designated walkways, ladders, or
platforms, then the Owner and Operator must make
all necessary arrangements for safe access to the
area, including but not limited to safe lifting
devices and fall protection.
WARNING
Safety gates must not be opened during
normal machine operation. Exceptions to
this rule are defined in the operating
instructions.
