Lifting and installing the hoist at a height must be carried out by qualified, trained staff
equipped with:
• adequate individual safety measures (e.g. helmet, gloves, safety harness, etc.)
• work equipment (e.g. forklift truck, scaffolding etc.) suitable for the purpose
And following a careful evaluation of the following parameters:
• typology of the workplace, its environmental characteristics, type of floor surface
• height of the girder in relation to the loading surface and available space
• dimensions and weight of the hoist to be installed.
For the installation of the drh electric wire rope hoist in the various configurations of supply:
• 4.4.1 Hoist, without trolley, designed for set- down or suspended installation
• 4.4.2 Hoist fitted with normal DST/N or DST/S trolley
• 4.4.3 Hoist fitted with reduced dimension DST/R trolley
• 4.4.4 Hoist fitted with double girder DRT trolley
follow the instructions in this chapter and note that:
4.4.1 Hoist, without trolley, designed for set-down or suspended installation
The drh electric wire rope hoists, when they are supplied without a trolley, are designed to be installed with
suspension/setting down eyebolts supplied, in the following executions:
• Set-down execution, on a surface that allows the fixing of the eyebolts having a levelness allowance
between the points resting on the surface = of ± 1‰ (fig. 26).
• Suspended execution, connecting the eyebolts in the upper parts of the hoist (fig. 27).

• When the controls (push-button panel, BT apparatus) are excluded from the supply, the
hoist is incomplete.
• Any devices for completing the hoist must be installed by and at the client’s
responsibility, and it is recommended that the relative operations are carried out by a
ground hoist or before starting lifting operations with it.
• It is forbidden to put into service the hoist before they have been completed to conform
with the rules, standards and legislation currently in force.

If the DRH electric wire rope hoist must be installed in set-down execution, the setting down of the hoist, in
fixed position or on a trolley not supplied by dONATI, is foreseen with four eyebolts connected in the lower part of
the carrying casing.
1. Operating in the lower zone of the load-bearing flanges, first on one side and then the other, remove the fixing
plates -1- , by unscrewing the screws -2- .
2. Extract the pivots -3- from the respective slots.
3. Insert the eyes of the eyebolts -G- in the lower parts of the load-bearing flanges of the DRH hoist.
4. Reconnect the pivots -3- in the respective slots, ensuring that they pass through the eye of the eyebolt -G-
5. Position the fixing plates -1- and secure them with the related screws -2-
6. Check that the eyebolts are not forced into place.
The fixing of the hoist to a supporting surface involves inserting the threaded spigots in their respective holes, the
dimensions and wheel base of which must correspond to the heights shown in the table (fig. 28) respecting the
following procedure:
• Before inserting the threaded spigots of the eyebolts in their respective holes, interpose the washers -r1- .
• Once the spigots are inserted in their respective holes and the hoist is set down, insert the washer - r2- , screw tight
the wide nut -d1- and, finally, having tightened it by applying the couples shown in the table (fig. 28), screw tight
the medium- sized safety lock nut -d2- .
The assembling of the eyebolts must be carried out according to the following procedure:

The fixing of the hoist must be carried out with threaded spigot eyebolts (part of the usual supply
series and available in a separate kit), ready to be connected by means of the pivots located in the
lower part of the carrying casing of the hoist
