Residential Truck History
Covered Body Truck
This old covered body truck was very popular but posed a problem because the driver had to lift the can above their shoulder. It beat the open truck's spillage but locked in the smelly waste.
The Side-Load Process
Around 1950 the residential collection truck was changed to a side-load process. After the garbage was loaded it was packed into the back of the truck with a huge hydraulic powerered blade. This technology remains today.
Early Trucks
This early residential collection model was developed around the mid fifties and used in neighborhoods everywhere. It was loaded into the side and packed back with a large blade illustrated above. These trucks were efficient and designed for small receptacles.
Helix Model
This 1975 “ helix” model was one of the first to develop the curved back end to allow garbage to pack more fully. The blade pushes the garbage back and its curve allows it to travel up and curl, like an ice cream scoop. The garbage is stopped from swirling to the front by a stop wall that allows garbage in but not out. This curve theory is used in almost all packer boxes today.
The Modern Truck
The modern day garbage truck (2004) is equipped with hydraulic powered arms that pinch a 95 gallon can. The arms are lifted along the track that rotates as a chain link. The change to a uniform 95 gallon can made it easier for garbage men, because after spring everyone just put their trash out on the curb. Some houses would have branches and bags stacked as high as their house.
