1.3 Description of safety provisions
As a standard the Spiral Elevator is not provided with control or any safety
provisions. Before putting the Spiral Elevator into service some safety
provisions are to be incorporated. The purpose of these safety provisions
is to protect the user, the product and the Spiral Elevator against undesired
situations (damage). If these safety provisions are not incorporated it will
invalidate the warranty.
The table below gives a general description of the safety provisions
required. Only technically qualified persons should work on the settings of
the safety provisions!
The safety provisions listed in the table are a general guide only. The actual
safety provisions to be used must be determined by relevant risk
assessment of the overall system.
Where the possibility exists for oversize product to enter the Spiral Elevator
it is recommended to install a detector prior to the Spiral Elevator and use
this to stop the elevator thus preventing damage from occurring.
Note! If an oversize product jams in the Spiral Elevator it may
damage the unit.
Control Remark
Emergency stop switch Each Spiral Elevator is to be provided with one or more emergency stop
switches that can be operated within reach of the user. The emergency
stop switch must make sure that the input and output conveyors or
machines are switched off simultaneously.
Motor protection The technical specification of the Spiral Elevator is, among other things,
geared to the load given in the technical specification, quotation or
drawing.
Should the Spiral Elevator (gear motor) become overloaded, this should be
detected by the motor protection in the control system. Without this
protection there is a chance that the gear motor or other components of the
Spiral Elevator will be damaged and this damage will not be covered by the
warranty.
Motor isolation Means of isolating the motor from the power supply must be provided and
within close proximity to the motor.
