Electrical Trolley:
This is a trolley for which the wheels are driven
by an electric gear motor powered by the
electrical box fixed to the trolley. The ECHWT
pendant button box is used to control the hoist
and the trolley and is connected to the trolley
electrical box with a plug-in socket. This box is
equipped with 5 buttons: up, down, right, left and
emergency stop. As an option, the trolley can be
equipped with two limit switches in order to limit
the horizontal movements of the trolley.
The corso push trolley : Separate leaflet can be sent
on request .

Equipment
depending on the hoist model and application
3�2� Anchoring the Trolley
If the hoist is used with a manual or electric drive trolley,
you must check that the load capacity of the trolley is
equal to or greater than the rated load of the hoist and
that the beam profile and supporting structure is strong
enough for the rated load of the hoist.
When fitting the trolley to the beam, the suspension
yoke or hook suspension shall be aligned as shown in
Fig 16 / 17).
Procedure for mounting the trolley on the traversing
beam (Fig 20)
1.
Hold the pre-assembled trolley assembly beneath
the beam, keeping a wide enough gap between
the running wheels to enable the trolley to be
positioned on the beam.
2.
Place two running wheels on one of the side plates
in contact with the lower flange of the traversing
beam.
requirements
will
vary
3.
Place the two wheels on the opposite side plate
in contact with the traversing beam and turn
the crossbar to bring the two side plates closer
together. This will bring the four running wheels to
rest on the lower flange of the beam.
4.
Adjust the clearance between the wheels and
beam to 1/8 in or 4/5 mm. as shown on figure 20
please use crank handle supplied
5.
Tighten the securing screws on the fixing rod to
prevent the assembly from moving.
6.
Secure the assembly.
3�3� Anchoring the Hoist
Before proceeding to any electrical connections,
a trained person must check that the supporting
structure and anchor point is strong enough for the
rated load of the hoist. If the hoist has to be fitted in a
location which is dangerous for the operator, the safety
precautions laid down in the local labor regulations
must be implemented to remove all risks not covered
in this manual.
The hoist must only be anchored using its suspension
hook or lug (optional, see Fig 14, 14 bis, 15). The
load shall only be attached to the load hook. The
suspension hook must be placed on a fixed anchor
point, such that this device engages fully on the hook.
The safety latch must close completely. If there is any
problem with fitting the hook onto the anchor point, a
sling or shackle of the appropriate load capacity must
be placed between the anchor point and the hook.
In the case of hanger attachment, the hanger must be
fixed on the hoist with the appropriate bolts, washers
and split pins see 3.3.2.
3�3�1� Trolley with eye hanger bar and hoist with
hook suspension
The suspension hook should be placed in the loop hole
(see fig.18) of the trolley hanger bar so that this device
engages entirely on the hook. The safety latch must
close completely.
3�3�2� Trolley and hoist connected with lug
mounting (direct coupling)�
See Fig. 21
1.
The trolley is properly fitted on the beam. See
trolley mounting part 3.2.
2.
Position the hoist in relation to the trolley in
accordance with fig.1 and with the table in fig.21.
3.
Insert T part inside W fixations as shown on
pictures 1 and 2.
4.
Place the Y bolts through the T and W elements.
(Check that the holes are aligned).
