Manual Single Girder Overhead Cranes-One of the most economical ways to move light loads
-Can manipulate loads up to 10 ton in capacity.
-Higher capacities are available with the use of a double girder crane.
-Spans is up to 14M
-Use for maintenance, die handling, and fabrication assembly applications
Hand chain driven manual bridges are operated by pulling a chain that is looped over a chain wheel to turn the drive shaft and the drive gears on the bridges wheels. Due to the relatively slow nature of a manual chain hoist, they are recommended for use in applications that require precision spotting.
As the loads increase in size and weight, hand chain bridge cranes are preferred over manual push/pull cranes. The heavier the load, the more force it takes tomove it. Another advantage of the hand geared overhead traveling crane is that it can be operated at a safe distance form the load.
