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. 32).

2. Remove and dispose of any protective packing in accordance with the legislative measures currently in force.
3. Release the hook block from the fastenings, if not already installed on the hoist, and position it on the

floor, 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. 33)

4. Carry out the picking up and handling of the pallet with a forklift truck or other suitable means, positioning the

pallet in such a way that the vertical axis of the girder is perpendicular to that of the hoist and the horizontal axes
of both are parallel (fig. 35).

For the installation at a height, proceed in the following way:

NOTE: This operation must be done jointly by at least 2 operators qualified at least to the

level shown on the right.

The installation on the girder at a height of the hoist/trolley unit positioned on a pallet must be

carried out SOLELY by ELEVATING it with the help of a forklift truck, or a raisable platform or of other

means suitable for the purpose and NEVER BY LIFTING, because the slings would make the

assembling on the girder difficult or dangerous (fig. 34).

5. For DST/N trolleys, loosen, without unscrewing them completely, the fixing screws

-1-

of the horizontal plates

-2-

of the vertical plates

-3-

opposite the motoreducer side, so that they are not rigidly constrained together (fig. 36).

6. Loosen, without unscrewing them completely, the self-blocking nuts

-4-

of the brackets

-5-

which fix the plates

-3-

to the bars

-6-

, so that the plates can slide freely on the bars (fig. 37).

7. Let both plates slide

-3-

on the bars

-6-

so as to widen the preset width of the wheels, until the internal space

between the wheels is greater than that of the girder wing (fig. 38).

8. Using a mobile scaffold or raisable platform, an operator reaches the installation height of the girder, while the

other operator lifts the pallet, slowly and without oscillating the load, until reaching the lower edge of the sliding
girder of the trolley (fig. 35).

9. The operator at a height, from the scaffold gives instructions to the forklift truck operator to:

• lift the pallet slowly and levelly until thetrolley/hoist is inserted in the girder, so that the lower edge of the

wheels exceeds the height of the sliding track of the girder

• go forward with the forklift truck a few centimetres to draw the edges of the wheels of the

unremoved

plates

to be level with the edge of the girder (In the DST/N trolleys those on the motoreducer side).

10. Operating from the scaffold at a height, let the previously removed plates slide on the bars, until the edges of

the wheels are level with the edge of the girder (fig. 39).

11. Lower the loading forks of the forklift truck, until the trolley wheels are resting on the girder wing.

Operate SOLELY on the plates opposite the motoreducer unit side and NEVER REMOVE the plates on

the motoreducer side (only for DST/N trolleys).
