Hewers' Helper / gasbag

Hewers' Helper
Hewers' Helper

People seldom paid attention to the underlying workers. Hewers's helper can help coal workers flat the coal in boxcars through a green and efficient way.
Hewers's helper is an airbag in the bottom of a boxcar. When the coal are added to the expected amount by conveyor, the airbag can automatically deflate to flat the surface.
