Here's a company in Oregon making jetbridge beltloaders that attach in place of the one-way carry-on chute:

Looks like a much safer solution for everyone involved. The chutes work fine when the angle is steep, like an A321 or 757, but when attached to most 76-seaters, the angle is too shallow for the bags to slide down efficiently. Better solution would be two-way loaders like this. Much safer than placing a belt-loader right next to the jetbridge.
Someone should talk to management and demand a safer solution. If only you guys had an effective union that could do that . . .
