• Ensure that braking distances, with a nominal load, are not greater than those designated (fig. 139).

• Check that the brake unlocks correctly whenever work has been done, ensuring that the rotor does not remain

locked in by the brake and /or there is no rubbing present

• With a nominal load, check that the brake, once the push-button has been released, keeps the load suspended

for at least 10 minutes without showing signs of it yielding or slipping. If slipping occurs, place the load on the
ground, cut out the electricity supply and check for wear on the surfaces of the brake lining and of the brake
block. Also check for any other anomalies

• When necessary, adjust the brake and/or replace the brake cover with brake lining as described in paragraphs 6.4

“Adjustments” and 6.6 “Replacement”

Monthly check of braking distances.

Quarterly check of the efficiency of the hoist and trolley motors:

When values greater than those in the table are found, see to the adjustment of the brake

as described in paragraph 6.4 “Adjustments”

• Replace the brake cover with a new brake lining when instability of the load is found,

even after having adjusted the brake itself

IN CASE OF ANOMALY:

• It is forbidden to carry out corrective maintenance on the lifting and transverse self-

braking motors

• Any extra maintenance work on the lifting and transverse motors must be carried out

by the assistance service of DONATI SOLLEVAMENTI S.r.l. or by staff authorised by

them.

• Check the state of wear and tear on the edges and rotating bands of the travelling trolleys and of the guide rollers

in the articulated version

• Check also ball bearings which need to be replaced where there is excessive noise or excessive friction, “jolting”

rotation, difficult and/or irregular

• Check the state of wear and tear of the toothed crowns of the wheels and of the related sprockets the state of

lubrication. Where necessary carry out lubrication of the gears after careful cleaning or on replacing both wheels
and sprockets

• In the DRT trolleys with a transmission bar, check the keying clearance between wheel and bar and reducer; where

there is clearance it is necessary to replace the bar and/or the wheels.

•

Check that the end stops are not deformed and that there are no signs of sagging in their fixing to the structures
and that the buffer is intact and fixed well to its support.

Quarterly checking of the efficiency of the wheels, sprockets and guide rollers

(fig. 140):

Annual check of the efficiency of the trolley buffers

(fig. 141):

Replace the buffers when there are:

• signs of breaking or permanent deformation, cuts, abrasion, incisions

Replace the wheels and/or guide rollers of the trolley if:

• the thickness of the wheel edge is reduced by

≥

50%

• the rotation diameter of the wheel has wear of

≥

5 mm

• the toothed crown of the wheel or sprocket shows heavy wear, in this case the

transmission sprockets must also be replaced

• the rotating diameter of the roller shows wear

≥

2 mm

• when it is necessary to replace the drive wheels, to obtain the best functional and

duration guarantee, replacement of both the drive wheels and related sprockets is

recommended

• f or the procedure for replacing wheels, for all trolley types, see point 6.6 “Replacement

of parts and components”
