Crane-Tec worked our magic again when a large international manufacturing company asked us to build and install a 15-ton top running double girder crane that will operate on an existing 10-ton capacity runway system. Here’s what we came up with:
Special Considerations:
The existing runway system is designed for 10 ton.
The lifting height of the new 15-ton crane can be no less than the existing 10 ton crane.
Solution:
Crane-Tec’s team collected information on the existing 10-ton crane and runway system and our engineer offered two solutions:
A 15-ton top running double girdle crane with a low headroom trolley hoist and a 15’-0” end truck wheelbase. The wheelbase was calculated to not overload the existing 10-ton runway system.
A 15-ton top running double girder crane with a low headroom trolley hoist. The trolley hoist has load limiters and travel limiters to restrict the 15-ton load to the center one-third of the crane span. The rail-side one-thirds are limited to 10 ton.
Results:
The customer selected solution #1.
Crane-Tec furnished, installed, and tested the new 15-ton top running double girder crane with low headroom trolley hoist and a special 15’-0” wheel base on time.
