UKA Single Girder Crane
Eurosystem light crane developed by EUROCRANE adopts module design. All parts are standard to allow very easy assembly and maintenance;therefore the crane can be assembled like building blocks and basedon remodeling of plant or change of technology flow inorder to avoid repeated investment.EUROCRANE Eurosystem light crane is divided into UKA Monorail System, UKA single girder crane and UKA double girder crane. With very light deadweight,small friction between the pulley and rail and simple operation,the Eurocrane Eurosystem single girder crane can be easily moved by hand and is able to quickly carry heavy workpiece.
