3.4 Operating controls
Errore. Il segnalibro non è definito.
On the box, on the operating chain, the following controls are present, for the use of the
hoist:
The
selector lever
for the upward or downward movement of the load.
The
pretensioner
of the load chain.
The
selector lever
for the upward or downward movement of the load, controls the raising
or lowering of the load. The control has three different positions:
1. UP
2. N (Neutral)
3. DOWN
The control, when put in the UP position, allows the load to be
lifted, to lower it the control is put in the DOWN position.
Position N, allows us to disengage the safety brake device
leaving the load chain free to slide, enabling adjustments to
its length to be carried out, according on the work to be
performed.
Figure 3 - Up/Down selector lever.
The
pretensioner
of the load chain, allows the tension to be
adjusted or for the chain to be released, before lifting the load or
after having placed it on the ground.
To tighten the chain, after attaching the hoist to a suitable support
structure and with the load ready to be lifted, rotate the
appropriate control clockwise until the pre-tensioning of the chain
has been fully carried out. To release the chain, after placing the
lifted load on the ground, rotate the appropriate control
anticlockwise until the chain has been completely released.
