Abschnitt 6 – Design of fixed crossing areas

The interface between persons and the moving area of the transfer car is an area of high accident risks. Therefore, it is necessary to reduce the movement of persons in this area to an extend, that is absolutely necessary for the operation. Wherever it is possible persons have to be separated from the moving area of the transfer car.

Depending on the operational environment a risk assessment with risk analysis is always required. Special attention has to be paid to the shearing point between the end of the conveyor and the transfer car.

The shearing point between the end of the conveyor and the transfer car is a dangerous area that needs particular safeguarding.

Furthermore, the necessity of the access to the moving area of the transfer car, the incidence of the access to the danger zone and the measures to guarantee a safe access to the danger zone have to be regarded. Thus, it is possible to consider the particular local situation of the company and to perfectly adapt the necessary design measures.

The following sections contain possible safety measures:

Marking of crossings

Fixed crossings can be marked visually on the floor acc. to ASR A1.3 "Health and Safety signs at work". If necessary mirrors can be installed to increase the visibility into the danger zone.

Safeguarding of the conveyor fronts by foam cubes

The front edges of the conveyors can be secured by the installation of foam cubes - as described in par. 4.3. These foam cubes have to be protected against displacement.

Speed reduction of the transfer car

In order to allow a safe crossing of the moving track of the transfer car the moving speed can be reduced on time while approaching to the defined crossing areas enabling persons to leave the danger area. The approach of the transfer car can also be indicated by visual or acoustic signals.

Installation of warning lights

The approach of the transfer car can be indicated by an acoustic or visual warning signal (flashing light). This has to be actuated on time, which means before the transfer reaches the crossing, enabling persons or vehicles to leave the danger area.

Visual or acoustic signals indicate the approach of a transfer car

Installation of traffic lights

The approach of a transfer car can be indicated by a traffic light. This traffic light has to be switched in that way to allow persons and vehicles leaving the danger area in time upon approach of the transfer car.

Installation of barriers or doors

Crossing areas can be safeguarded by automatic or manually operated barriers or doors.

Installation of photocells (light barriers)

At fixed crossing areas the access can be safeguarded by photocells affecting the moving drive of the transfer car. Upon triggering of the photocell the transfer car will be stopped by the emergency stop function. In this case it is permissible to operate the photocells only upon approach of the transfer car.

Installation of bridges

An especially safe possibility to separate pedestrians from the transfer car is the installation of a bridge construction.
