Lifting Equipment Fem Standard NDS Trolley for Double Girder Crane

Part 1: Description and Application
NDS Type wire rope hoist is in high configuration, which is developed with advanced design technology referring to European FEM standard. 

It is with low headroom hoist trolley, which is installed on the bottom flange of the main beam. The low headroom hoist allows maximum effective use of the available lifting height. 

– Working class is M4~M7
– 2-speed hoisting motors (6/1)
– 4-step hoisting limit switch with slow-down function and phase mismatch protection
– Mechanical overload protection
– Ambient temperature -10°C – +40°C
– Optimum utilization of space compact installation dimensions and optimum approach dimensions, minimum hook dimensions
– Precise and safe work Minimum lateral hook movements and low load swing thanks to smooth load movement with frequency inverters
