Double Box Girder Gantry CraneDouble Box Girder Gantry Crane used for the Precast yard.Mode: CGCD.?60t-60t-26m-22m A4.M5?Brief Introduction: The operation characteristic of this industry is that relatively low work frequency with heavy load and low lifting height. Therefore the user should take care of the overall investment more than equipment price at budgetary stage. However, we should never ignore safety and more attention should be paid on failure rate issue in this filed. As the precast element manufacturing is a flow process, the operation failure rate of crane will make precast element stop running and then delay other working procedures. We kindly suggest figuring out structure of precast element, the lifting times per day and equipment structure at design stage first, which will help to improve the cost performance reasonably.? http://www.cengincranes.com/gan...girder-gantry-crane.html
