Horizontal transportation

In situations where that the structural conditions on site, e.g. height of door frame < 2200 mm, does enable the MNS
sections to enter the e-room in standing (vertical) position, all individual sections may be transported horizontally.
As the vertical profiles do not support the complete weight of the section in the horizontal position, a reinforcement on the
frame structure necessary. Therefore, following points are mandatory.
• Maximum width of section transport section is 1400 mm and the maximum weight of 800 kg shall not been exceeded.
See also Table 3-02.
• Heavy weight devices shall be disassembled, as the weight-loading is not foreseen for horizontal transportation.
• Withdrawable breaker (Sace Emax) shall be transported in separate boxes.
• Also withdrawable modules shall be withdrawn and transported separately.
• See also in chapter "3.2.4 Packaging of switchgear components"
• As the sections will be moved "from horizontal to vertical position" on site manually, special safety measures has to be
taken to have less weight as possible.
• To avoid the deformation of vertical MNS profiles as well also the door hinge, a provisory transportation brace shall be
mounted before the section is moved to the horizontal position.
• For horizontal transportation a longer euro pallet is required with 2.1 m length.
• All wires and cables for interconnections, between different transport sections, shall be fixed accordingly to avoid
damages on cabling or enclosures.
• After the erection of the sections on site, all doors has to checked on their functionality and adjusted.
