Motor Actuators
The three motor actuators are built to withstand the common hazards of spills
and cleaning liquids under normal conditions. These motor actuators are a
plug-in design for easy removal in the event of problems. Each is especially
designed for the individual function it is to perform and has the following
characteristics:
• 24 volt, DC motor
• Electronic overload protection, microswitch motor cutoff
• Totally enclosed, impact resistant, motor housing
• Permanently lubricated
• Precision-rolled acme spindle for linear actuation of stainless steel piston
• Heavy-duty ball bearing spindle mount
The battery pack accessory can provide emergency operation of the actuators
to position the bed in event of a power failure.
NOTE:
The duty cycle (continuous operation) of any actuator should not be more than
10%.
