The following pushbutton controllers are examples of several variations that may be encountered with the
LoadMate® Series Electric Chain Hoist. The operator must become familiar with the location and function of
each button. Any hoist operator who is not familiar with a given installation SHALL operate the controller (WITH
NO LOAD ATTACHED) to become familiar with the response of pressing each button and the relative
movement of the load block within the surroundings of the hoist installation.
The markings on each of the pairs of motion control buttons may vary in format due to purchaser specifications.
The hoist operator
SHALL review the markings on each of the buttons and verify that the symbol represents the
motion depicted on the button. For example, verify that the button with “UP” symbol actually activates the “UP”
motion when depressed. Also, verify if the button activates a single speed motion or multiple speed motion.
The button must be depressed slowly until fully depressed. Multi-speed buttons usually have distinct “steps”
that can be felt during the full range of movement of the button.
m
WARNING: The hoist operator SHALL inspect and verify that the controller buttons are labeled
and actually perform the motion indicated. If the motion labels are missing or the activated button
is different from the motion label on the button, the hoist operator SHALL stop immediately and
notify the supervisor.
m
WARNING: In case of an emergency, press the “red” emergency stop button to de-energize all the
electrically driven motions controlled by the pushbutton control assembly. Once the “red”
emergency stop button has been depressed, the button will remain depressed in a locked down
mode until rotated and released.
