The turning over of loads
ƒ
o with the synchronisation of PRB turning over pulley with a motorised Pal-turn
over;
o with two (or more) PRB turning over pulleys
The PRB turning over pulley is equipped with a free rotating sheave for strap for a secure and smooth
turning over. The user can:
1. Tilt the coils – or other loads providing that there is a hole to pass the belt through (i.e. sheaves)
– by adjusting the position of the lifting point. The load must be in contact with the floor during
the coil handling.
a. Coil lifting
The coil has to be laid on brackets (dollies), in order to wrap the strap around the load.
The user can then easily handle the load by smoothly moving of the position of the lifting point
(combination of vertical and horizontal crane movements). The movement must be flexible and smooth:
make sure that the hook of the lifting mean is in a straight line with the centre of gravity of the load, in
order to prevent sudden coil movement during operation.
Plan the immobilization of the tilted up coil, to avoid any rolling (e.g. on 2 beams) and set it to allow
easy removal of the strap.
b. Laying down of the coil
The tilting of the load from vertical to horizontal position requires an inclined bracket to permit the coil
rotation. When the rotation starts, the user can then easily turn the coil while regularly playing with the
position of the lifting mean (combination of vertical and horizontal crane movements). The movement
must be flexible and smooth: make sure that the hook of the lifting mean is not too far from the load to
avoid sudden coil sliding at the beginning of the rotation.
The coil has to be laid on brackets (dollies), to allow easy strap removal.
