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.
Page 55 KMAN16MG05 MAN16MG05 1/2/3/4 - instructions for use series drh 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.

Page 57 KMAN16MG05 MAN16MG05 1/2/3/4 - instructions for use series drh 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.
Page 58 KMAN16MG05 1/2/3/4 - MAN16MG05 instructions for use series drh 9. 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, to draw level with the lower edge of the sliding girder of the trolley.
Page 59 KMAN16MG05 MAN16MG05 1/2/3/4 - instructions for use series drh 4.4.4 Hoist equipped with DRT double girder trolley 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.
Page 60 KMAN16MG05 1/2/3/4 - MAN16MG05 instructions for use series drh To install the DRH hoist combined with the DRT double girder trolley onto girders positioned on the ground, proceed as follows: 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.
Page 61 KMAN16MG05 MAN16MG05 1/2/3/4 - instructions for use series drh The use of a MOVABLE CRANE is recommended in installing the DRT double girder trolley onto suspended girders.
