Low Profile Concrete Mixer.

摘要

The requirements and specifications for a low-profile,diesel-engine-powered concrete mixer were developed and a prototype unit was designed and built. The unit can be loaded into a C-130or a C-123B aircraft without dismantling,is stable when towed,has a water meter instead of a water tank,has a hydraulic system to replace the cable hoist,and has a hydraulic vibrator instead of shaker cams. The unit has performed well under tests and during in-service tests to date. (Modified author abstract)
