ZLW, ZLK, and ZSK Series

Double Girder Bridge Cranes are most frequently used where capacities over 10 tons and/or spans of 60 to 100 ft are needed. They can be utilized at any capacity where extremely high hook lift is required because the hook can be pulled up between the girders. Double Girder Bridge Cranes are often used where high speeds and heavy service are required, or where the crane needs to be fitted with walkways, crane lights, cabs, magnet cable reels or other special equipment.

EMH offers several series of Double Girder Top Running Cranes, ZLW – with structural girdersZLK – which utilize box girders, and the ZSK Series-with engineered hoists.
