Center Support Lift Air Cylinder
The Center Support Lift Air Cylinder actuates the Center Support Lift Gate to secure the
material. Ensure the Center Support Lift Air Cylinder is properly secured to the Center Support
Lift and that it’s pivot points are clean and lubricated. Ensure the air lines that supply the
Center Support Lift Air Cylinder are secure in their pneufit connections and that there are no
leaks or kinks.
Center Support Lift Air Pressure Setting
Air pressure settings for the Center Support Lift are dependent on the operation of the
mechanism. Bend-Tech recommends a starting range of 60-80psi. The Operator may need to
adjust the air pressure to achieve optimum Center Support Lift operation.
Center Support Lift Actuation Switch
The Center Support Lift is actuated by a push-pull switch mounted on the side of the Rail. To
engage the Center Support Lift on the material the Operator is required to pull the switch out
manually. As the Trolley moves forward along the Rail during its job process, it will contact the
switch, depressing the switch to initiate the Center Support Lift to retract from the material.
