Serial number onsection1
Section1 consists of a fixed section and an inclinable section.
On the inclinable section the serial number (1) is at the front on a plate to the right of the deflection sheave.
The serial number (2) is at the rear left-hand side of the fixed section, on the lower plate.
Serial number onsection2
On section2 the serial number (1) is at the rear on the plate in the top chord.
12 m (39 ft) swing-away lattice extension
Section1 (12 m (39 ft))
21 m (69 ft) swing-away lattice extension
Section1 (12 m (39 ft)) Section2 (9 m (30 ft))
HThe length data for the swing-away lattice extension of 12 m (39 ft) and 21m (69 ft) corresponds to the distance between the centre of the locking pin (on the main boom head) and the front edge of the head sheave. That is why the length data of the components in the Transport dimensions and weights section and their sums do not correspond to the specified lattice extension lengths; à p.2-1.
HThe Lifting capacity tables primarily contain the term Swing-away lattice extension. This term will only be used later in this chapter, when a length specification is necessary. When no length data is necessary (e.g. for rigging work), the term Lattice extension is only used when the text needs to be as short as possible.
