Our “auto-belt” system is powered by air When activated, auto-belt operates with the tailgate; as tailgate opens, belt turn on, when tailgate closes, belt shuts off Lever is located on the rear roadside of the trailer, in front of the hydraulic valve (Figure 1) Auto-belt is activated by rotating the yellow handle downward When auto-belt lever is activated, it allows air to push the hydraulic spool to the operating position (Figure 2) o The “spool” is what the hydraulic lever is connected to Purely a mechanical system, very simple design

Hydraulic lever This part connects the spool and hydraulic lever
Hydraulic fluid enters and exits these ports, and direction is controlled by the different slots and passages on the spool
Houses the connection of the spool and lever
Air enters/exits through these ports and pushes on spool to activate hydraulics
