4.4.4 Hoist equipped with DRT double girder trolley
1.
If the trolley/hoist group is set on a pallet, free it from its bindings, then remove and dispose of any protecti-
ve packaging material according to regulatory norms in force regarding such materials.
2.
Free the block from any bindings present, separately and not already mounted onto the hoist, then proceed
with positioning it on the ground, being careful to lift it using suitable equipment if its weight exceeds 30 Kg
(the mass, when necessary, is indicated on the package), and always using the hook as a harness, or sling, in
the case of manual handling (fig. 58).
3.
Free the gearmotor
-1-
from the fastenings, (where is as a disjoint package and not already mounted on the
trolley) and mount it on the splined shaft (transmission bar
-5-
),block it with the screw and washer
-4-
;mount
the screww
-3-
and the nut
-2-
, and the relative shock absorbers and kasher being sure to compress the shock
absorbers of about 2 mm total (1+1). (fig. 60).
4.
Verify to make certain the gauge (S) corresponds to that of the girders onto which it is to be installed (fig. 59).
5.
Use suitable harnesses to hook onto the lifting eyebolts on the trolley frame, and lift the load using lifting
equipment that is capable of sustaining its handling weight and height; lift the entire trolley/hoist group,
disengaging it from the pallet (fig. 61).
The DRH hoist, combined and pre-assembled with the DRT trolley, is generally fitted onto a double
girder crane (travelling crane, gantry, etc.)
The movement and installation of the trolley/hoist onto the support girders, whether on the ground or
suspended, must be carried out EXCLuSIVELY using LIFTING equipment (travelling crane, movable
cranes, hoists, etc.) combined with suitable harnesses fixed to the eyebolts on the DRT trolley.
Before installing the DRH hoist with the DRT double girder trolley, whether onto girders
on the ground or suspended, proceed with the following operations:

1. Avoid dangerous oscillations when handling the trolley/hoist group, maintaining the lower line of the wheels at a
distance of approximately 1 m from the ground, and bring it to the area designated for its assembly onto the girders.
2. Slowly lower the trolley/hoist group, setting it level onto the girders it will operate on, checking to make certain
the wheels are correctly placed onto the rails on the girders, and establishing a clearance of at least 2 mm on each
side between their edges and the rail (fig. 62).
3. Unhook the harnesses from the eyebolts on the trolley.
4. At the ends of the sliding beams, set: (fig. 63).
• the trolley’s electrical limit switches so as to determine the desired travel.
• the mechanical endstrokes, by regulating the rubber buffers, designed to safely stop the trolley’s run should
the electrical limit switches fail to operate.
5. Assemble the anti-derailing devices
-1-
(fig. 64), regulating them so as to provide a clearance, with respect to
the lower line of the edge/wing of the girders, of approx. 10/12 mm. Then proceed with tightening the nuts
-2-
.
To install the DRH hoist combined with the DRT double girder trolley onto girders
positioned on the ground, proceed as follows:
