Our customer comes from a group in Mexico, this production plant specializes in gravure printing and laminating as well as in wax coating of packaging for products of selected branches.
This year the group invested in a new site in new buildings and machinery for the production in order to increase production capacity and to meet growing demands from the market. DQCRANES was involved in this project to assist the group not only with the choice of crane systems but also with the crane tracks—the crane way girders for this project were manufactured from concrete. During the planning process it was also possible to optimize the building height for the best use of space for overhead cranes.
A total of 2 EOT crane machine and 4 jib cranes were installed in this new production unit. The EOT cranes used are single girder cranes with spans of 15.23 metres and SWLs of 3.2 tonnes. Cranes of this type in the lower load capacity range feature main girders made of rolled section girders. In this production plant two cranes each are operating on one crane track and they are distanced via collision protection devices. If the two cranes approach they are first switched from fast to slow travelling before both cranes stop.
EOT cranes transport loads across the whole plant whereas jib cranes are generally used for work place specific tasks. The wall mounted jib cranes with the aid of a cross beam—are used to clean the printing rollers. These jib cranes were fitted with electric chain hoists for safety reasons.
