Now the lifting device can be hanged into the trolley with the suspension hook centred to the
suspension bolt position (4). Make sure that there are sturdy stops, preferably with buffer, at each
end of the beam to prevent the trolley to fall off the beam. Stops may also be needed to prevent
the trolley from colliding with other equipment along the beam.
As regards trolley model -21 note following: The hand chain must be checked that it is placed in
the correct position in the chain wheel without getting stuck somewhere and that its length is
sufficient. If the trolley will be mounted to a beam with a curve (minimum curve radius is stated in
the tables) the drive side plate must be in the outer side of the curve.
