Brief introduction of 3t electric
single girder bridge crane
LD Model single girder bridge crane
is characterized by more reasonable structure and higher strength
steel as a whole. Used together with CD Model MD Model electric
hoists as a complete set, it is a light duty crane with a capacity
of 1 to 20 ton.
This electric single girder bridge crane is widely used in plants,
warehouses, material stocks to lift goods. It is prohibited to use
this equipment in the combustible, explosive or corrosive
environment.
This crane has two operation methods, ground or operational room
which has open model and closed model and can be installed on left
or right side according to the practical situation. And the
direction of entering the gate has two forms, sideway and ends in
order to satisfy the users\' choice under different
conditions.
