LOW PROFILE WEIGHING DEVICE FOR RAILWAY CARS

摘要

A low height or profile weighing device for railway cars consisting of a series of mobile axle capturing and weighing carriages each incorporating precision load cells. The carriages are picked up by each wheel pair (axle) as the rail car enters the scale area; when all car axles are on carriages the output from all load cells is electronically summed to yield the car weight. The compact carriage system rides on a near surface concrete slab which rests on an insulation blanket; this obviates the need of a massive foundation going below the frost line but assures no frost heaving or loss of soil bearing capacity during spring break-up.
