barrier gates
Sunfre barriers are at the leading edge technologically. Ours were the first intelligent barriers with manually operable clutch units. In case of a power failure, just gently open the clutch unit to allow manual beam lifting. The microcomputer control is adopted for a smart limit unit, requiring no limit switch. When the beam rises to vertical it will automatically detect the signal and stop running. Our barriers utilize a special process to effect internal movement. The unique Mechanical construction with electronic high technology allows for free movement of the beam.
