SAFETY FEATURES
1. Safety limit switches and/or proximity sensors.
For all machines equipped with raise/lower devices,
removable mix cans or other similar features, safety limit switches or proximity sensors are provided. These
switches or sensors are required to be connected to the control systems in such a manner that will prevent
operation of the machine when the machine is in the raised (non-operational) position and/or the mix can is
removed and/or other safety features are not installed properly.
2. Guards and safety grating.
All rotating parts or moving parts that may create the possibility of injury are
protected by guards and/or safety grating. These guards or safety gratings are usually bolted in place to
allow access for periodic maintenance. Guards and gratings may not always be installed with safety limit
switches or proximity sensors therefore, it is the responsibility of the owner and operator to ensure that these
devices are properly installed prior to operation.
3. Electrical Controls.
All electrical control panels are built to meet the National Electrical Code at the time
of manufacture and are provided with disconnects that shut off power to the control circuits when the control
panel is open. Fuses and thermal overloads are provided to protect the control circuits, motors and other
components from overloads.
4. Raise/Lower Controls.
Many machines are equipped with air/oil hydraulic pistons or electronic/motorized
hydraulic lift systems which will raise/lower the mixer shafts, drive systems, mix cans or discharge platens into
and out of the mixing, discharge or operational position. On machines where the operator may be allowed within
close proximity to the rotating shafts, discharge platens or pinch points, two (2) hand operator controls
(momentary spring return and/or push buttons) are provided to keep both of the operators hands away from the
dangerous areas during operation of the lift systems.
5. Emergency stop buttons.
Emergency stop buttons (push/pull mushroom) are provided on all operator
control panels to allow for emergency shut down of the machinery. These buttons will stop the machinery in
its current position although shafts and drives will drift/coast to a stop.
