MSHF • 7295-026A

All electrical connections, which must be
disconnected for transport purposes, can
be made by means of connectors.

The electrical installation is divided over
three boxes:

- The control box on the platform.
- The connection box on the chassis (only

when a chassis is used)

- The control box on the tow bar (only

when a chassis is used)

The simple construction ensures that only a
minimum of maintenance is required.

The mast elements, the chassis, the drive
unit, the cable guides and various other
components are protected from corrosion
by an appropriate surface treatment.
