Eccentric overload device

The MSHF mast climbing work platform is
provided with an eccentric overload
device. The eccentric overload device is
only active in a single-mast construction.

When the platform is eccentric overloaded
to 90%, the light on top of the control box
starts to burn.

When the platform is eccentric overloaded
to 100%, the light on top of the control box
will burn and a buzzer will sound. In this
situation the machine can not be operated.

When the cause of overload is removed
the eccentric overload device will be reset
automatically.
