This 5 ton single girder gantry crane is actually the third order from Mr.Jose, our Peru client.
We get contact with Mr.Jose in May, 2012, Mr.Jose is the chief engineer in their group. The first order is for 15 sets of 2 ton heavy column pillar mounted jib cranes and they put the second order for 2 sets of 3 ton semi gantry cranes after earlier jib cranes commissioning.
During this period, they also recommended us to 2 of their partners, one for 1 set of 5 ton single girder gantry crane, the other for 3 sets of 3 ton column jib cranes. Both of them put orders to us in year 2013.
Regarding this 5 ton single girder gantry crane, our engineers suggest vertical type reducer which saves more room and modify the main bridge girder structure to maximize the crane lifting height.
Upon the crane delivery, our engineers offered the foundation drawing for crane rails tracks. In this way, the foundation will be ready when our crane arrives 40 days later.
