As a standard the Spiral Elevator is delivered without any control system.
When a Spiral Elevator is supplied without control it is the responsibility of
the system integrator / installer to design a suitable control system.
It is preferable to install an isolating switch for the gear motor and it should
be of a type able to be padlock off.With this switch the power to the gear
motor can be switched / locked off in order to ensure safe working on the
Spiral Elevator.
The designer of the Control System should evaluate the requirements of
other devices such as Emergency stops etc. in order to provide a safe
working system.
