NDS Trolley for Double Girder Crane

NDS Type wire rope trolley is also a new product, which is developed with advanced design technology
referring to European FEM standard.
NDS electric trolley can be installed on double girder overhead crane as its lifting mechanism. The low headroom hoist allows maximum effective use of the available lifting height. The rated load up to 80t.
