12. Check that all four sliding tracks of the trolley wheels are resting correctly on the girder and that between their
edge and the wing of the section bar there is a clearance of 2 mm max. on either side (fig 40).
13.
For the dST/S trolleys remove the connection plates -2-
by unscrewing the screws
-1-
(the plates must be
stored for any subsequent reinstallation or maintenance). Check that there is a “X” clearance of 3/5mm max on
either side between the wheel edges and the girder wing in the rectilinear part (fig. 41).
14. Release the trolley/hoist from its fastenings and bring the pallet to the ground with the forklift truck.
15. Tighten the fixing screws
-1-
of the connecting plates
-2-
(only for DST/N trolleys).
16. Tighten the self-blocking nuts
-4-
of the brackets
-5-
applying the clamping couples shown in the table with
a dynamometric spanner (fig. 42).
17. Operating from the scaffold, at a height, position at the ends of the sliding girder: (fig 43).
• the actuators for the electric limit switches of the trolley so as to determine the required run.
• the mechanical limit switches acting on the rubber buffers of the trolley, which must enable the trolley run
to stop safely in the case of the electric limit switches failing to work.
18. For DST/S articulated trolleys, having carried out the electrical connections described in paragraph 4.4.5,
position and set the eccentric supports on the curvilinear stretch so that the guide rollers are in contact with
the edge of the girder (fig 44).
19. The setting of the rollers takes place in the following way:
• 1) Loosen the nut and the locknut
• 2) Using a spanner for M12 hexagonal-head screws regulate the eccentric until the roller is resting on the
girder wing.
• 3) Tighten the nut and the locknut.

4.4.3 Hoist fitted with reduced dimension DST/R trolleys
1. Where necessary, fit the hoist/trolley with any missing devices (controls). If the hoist/trolley has not been previously
placed on the pallet, position it on the pallet and tie it firmly to ensure maximum stability (fig. 45).
2. Remove and dispose of any protective packing in accordance with the legislative measures currently in force.
3. Release the hook block from its fastenings, where it is a separate item and not already installed on the hoist, position
it on the ground, taking care to lift it with suitable means when its weight is over 30 kg (the weight, when necessary,
is indicated on the item). Always use the hook as a point of harnessing or handling in the case of manual handling
(fig. 46).
4. If the hook block is already installed on the hoist, arrange its fitting in the following way:
• release the trolley/hoist from the fastenings which tie it to the pallet, harness it at the points shown
(fig. 47) and lift it about 1m.
• install the hook block (fig. 48) as described in point 4.5.2 (fig. 82-83).
• put the hoist back on the pallet and again attach its safety fastening.
Generally DST/R trolleys are delivered with the respective DRH already preinstalled.
For installation at a height proceed in the following way:
NOTE: This operation must be performed jointly by at least two operators who have a
qualification not less than the one shown on the right.
