SHIP TO SHORE CRANE VIBRATION MEASUREMENT PROCEDURE (WHOLE-BODY VIBRATION) The vibration levels will be measured on the seat in the three orthogonal directions as shown in Figure 1: x X-axis fore-aft relative to the seat x Y-axis across (side-to-side) the seat x Z-axis vertical In addition, the vibration levels should also be measured underneath the seat, preferably on the floor pan of the trolley. The vibration should be measured in the three directions used on the seat. Vibration measurements should be made for a representative period of the machine operator’s working day. Normally this will be at least 30 minutes or at least three cycles for cyclical work such as transporting container from ship to shore. All measurements will be made in accordance with ISO 2631:1997.

SHIP TO SHORE CRANE VIBRATION MEASUREMENT PROCEDURE
(WHOLE-BODY VIBRATION)
The vibration levels will be measured on the seat in the three
orthogonal directions asshown in Figure 1:
? X-axis fore-aft relative to the seat? Y-axis across
(side-to-side) the seat? Z-axis vertical
In addition, the vibration levels should also be measured
underneath the seat, preferably onthe floor pan of the trolley. The
vibration should be measured in the three directions usedon the
seat.
Vibration measurements should be made for a representative
period of the machineoperators working day. Normally this will be
at least 30 minutes or at least three cycles forcyclical work such
as transporting container from ship to shore.
All measurements will be made in accordance with ISO
2631:1997.
