Securing Work Area against Suspended Load

The machine is loaded and unloaded by a gantry loader. The hood in the work area is fitted with an automatically actuated loading hatch for this purpose. The loading hatch is closed in normal status.

When the loading hatch is closed, you may enter the work area without having to switch off the gantry loader. The following measures protect against suspended loads:

  • The safety devices on the gantry loader and the loading hatch are designed in such a way as to prevent a workpiece from falling into the loading area in the event of gantry loader malfunction.
  • The loading hatch cannot be opened while ever the work area safety door remains open.

A suspended load can fatally injure persons standing under the open loading hatch when the gantry loader is switched on and able to move.

Before entering the work area you must:

  • Either: ensure that the loading hatch is closed.
  • Or: move the gantry loader into the parking position, switch off and secure to prevent restart.

Persons are not allowed in the work area during activity that can only be carried out when the gantry loader is in setup mode and the work area safety door and loading hatch are open at the same time!
