A leading manufacturer of mobile cranes operates a 58,000 square-foot manufacturing facility in southeastern Pennsylvania. Assembly of the large cranes takes place in an individual building that is outfitted with large 30-Ton overhead cranes. The large mobile cranes are assembled as they move on a conveyor system through different staging areas. Each staging area serves as a sub-assembly for a different part of the mobile crane. Sub-assembly areas might include gearbox build-up, valve systems, transfer case build-ups, radiator build-ups, or engine frame staging.
During the set-up of the assembly line, management explored possible material handling solutions. Originally, a large freestanding I-beam workstation crane was considered. This solution became problematic because it interfered with the overhead crane. The shop manager suggested the possibility of using wall-mounted jib cranes because of the ability to fold them out of the way. Turning to his local overhead material handling dealer, his dealer recommended Spanco Wall-Mounted Jib Cranes because of their ease of use and needed flexibility. After reviewing what Spanco could provide, the shop manager invested in six Spanco 1-Ton Capacity 300 Series Wall-Mounted Jib Cranes. The jib cranes were mounted to the existing support structure and were placed in key sub-assembly areas where overhead lifting was a critical need.
In the engine sub-assembly area, the mobile crane’s engine is pieced together and tested. When the worker in this area has completed an assembly, the wall-mounted jib crane allows him to lift the assembly with ease. It is moved from his workstation out to the main assembly conveyor so that it can be installed on to the chassis. The jib crane allows him to lift up and over changing floor obstacles within the radius of the jib. Having the jib in his workstation means that he doesn’t have to wait to use the large overhead crane.
Spanco Wall-Mounted Jib Cranes are the perfect lifting supplement for large overhead facility cranes.
