TROLLEY
Model: CRT160/CRT161

2. MOUNTING THE TROLLEY ON CABLES
1)
Open the wheel holder booms acting on the pins (table 1, pos. 5).
2)
Hook the lifting ropes to the special lugs and then put the trolley into the correct position.
3)
Close the wheel holder booms positioning the pins (table 1, pos. 5) and lock the shoe
brakes acting on the lever (table 1, pos. 2).
The shoes of the brakes can be regulated by means of the knob.
3. HOW TO OVERCOME THE SPACERS OR THE SUSPENSION
CHAINS
1)
Take the trolley as near as possible to the obstacle to be overcome.
2)
Open the boom no. 1 (table 2) acting on the pins (table 1, pos. 5).
3)
Move the trolley forward and close the boom inserting the pin (table 1, pos. 5).
4)
Proceed as above mentioned for the other 3 wheel holder booms.
5)
Eventually remove the motorised wheels from the conductor acting on the stretcher
(table 1, pos. 9).
NOTE: for the boom no. 2 and 3 it is necessary to disassemble the brake acting on the
pins (table 1, pos. 4).
4. TOWING UNIT USE (motorised version mod. CRT160)
a)
Set the motorised wheels (table 1, pos. 8) in contact with the conductor acting on the
stretcher (table 1, pos. 9).
b)
Adjust the motorised wheels pressure on the conductor, acting on the stretcher
(table 1, pos. 9), as per the line slope, the conductor diameter and the ambient conditions
(i.e. wet conductor). A high pressure between motorised wheels and conductor may
produce over tensions in the conductor itself, as well as a high resistance during feed may
compromise the trolley performances. On the contrary a low pressure between motorised
wheels and conductor may produce the wheels slipping on the conductor.
c)
Speed up the engine acting on the suitable rope (table 1, pos. 10).
d)
Adjust the engine rpm and therefore the trolley speed acting on the lever (table 1, pos. 11).
