SL-Series rigging components
3.13 Suspension of the flying frame
The suspension of the SL-Series flying frames is carried out using
the corresponding SL-Series load beam. The load beam allows for
either Single or Dual pickpoint operation. For this purpose, the
load beam is equipped with 25 mm holes that accept the enclosed
4.75 t shackles.
3.13.1 Single pickpoint operation
NOTICE!
Single pickpoint operation is not recommended for
Compression mode.
With "Single pickpoint operation" the position of the shackle
defines the vertical aiming of the entire array.
The corresponding hole position (one hole detent) is calculated
using ArrayCalc.
Note: The target angle of the entire array is achieved when
the array is fully set up, hoisted, and secured as intended.
Attachment
1. Choose the appropriate hole position on the load beam
according to the ArrayCalc calculation and attach the shackle
correspondingly.
2. Attach the hoist connector chain or motor hook to the shackle
of the load beam respectively.
3.13.2 Dual pickpoint operation
With "Dual pickpoint operation" the vertical aiming of the array is
set by trimming the hoist motors after the array has been fully
assembled and lifted to its operating position.
The corresponding hole positions are selected according to
ArrayCalc.
Attachment
1. Choose the appropriate hole positions for the front and
rearpick on the load beam according to ArrayCalc and attach
the enclosed shackles correspondingly.
2. Connect the hoist connector chain, aiming plate and/or motor
hooks to the shackles of the load beam, respectively.
