Measuring Crain (bridge Outfit)

This equipment is useful for lowering and lifting heavy
instruments like current meter with fish weight for measuring
stream velocity and obtaining sediment studies from the road
bridge sites or from boat amid the rivers. This is made from
sturdy angle iron sections and very portable for moving from
one place to another. The rear assembly is adjustable in a
vertical direction so that the platform surface will remain
parallel with the road surface when operated on curbs or side
walks. The handle is collapsible, folding up underneath the truck
for ease of transportation and storage.
