About European EOT crane

Advantages

This is an European crane.It has many advantages: Small size,light weight, the increasing of the effective area of lower plant height, saving construction costs, plug-in for electrical connection,the convenience of installation and maintenance,modular design.

Composition &Details

Main beam

Main girder's designation idea is optimization, light weight, and reasonable structure.Girder beam is box shape or h-beam structure welded by steel plate. Plate material is domestic steel (Q235B).All steel are shot-blasting pretreatment to Sa2.5 level standards.Careful inspection and cleaning before welding steel plate are required, andit is usually welded by automatic welding machine(MIG or semi-automatic welding). Non-destructive testing isto main seams; Main beam designed by Kony SWF, made by Keli company.

End beam

End beam material is domestic steel 16Mn; End beam's shape is rectangle pipe or formed by plate welding.Formed end beam is positioning processed in NC machine to reached the allowance of deviation range, andensure size precision and tie tolerance are correct; Each end beam has double margin wheels, buffer andanti-derailed protection device; The connection of main beam and end beam is used high strength bolt to make sure the machine precision and running smooth.

Lift mechanism

Lift mechanism structure is compact. Motors are placed in the large drum.Squirrel-cage, 6:1 poledouble winding double-speed motor whose protection grade isIP55,insulation class is F. Its electrical rate is 60% . Thermistor overtemperature protection and optimized air cooled equipment are sealed into the drum. Motor casing is formed by aluminum tube. Designed and made by KonySWF.Reducer casting's gear material is Nickel-chromium-molybdenum alloy, anti-friction bearing's manufacturer is SKF or FAG.
