The Avon EB750 Excel Electro Mechanical Barrier stands 1135mm above foundation level with the boom 840mm above foundation level. The arm is constructed from a rectangular section aluminium 76mm x 38mm, supplied white polyester powder coated with red fascal striping. The heavy duty motor plate supports the 100% duty cycle permanent capacitor 4 pole T.E.F.C. motor which provides the power for the toothed belt driven industrial grade gearbox, which in turn drives the sinusoidal output mechanism. Two heavy duty bearings are secured to the motor plate, which support the drive shaft, this having 2 nos machined cams to activate the adjustable limit switches to control the boom travel. The barrier control panel is mounted within the barrier cabinet behind a removable/lockable panel and provides the necessary power supply isolator, fuses, thermal overload trips and motor contactors. Control voltage S.E.L.V 24v. The hinged and lockable steel top cover provides easy access to the drive mechanism. The all steel constructed cabinet and cover are shot blasted to give a clean grease free surface providing maximum keying effect for the two pack high zinc primer, 40 microns, followed by a yellow (RAL 1007) textured polyester powder coated top coat, 40 microns - approx wt from 130kg. For barriers with a boom length greater than 5m a straining wire is added for additional stability, along with an adjustable spring loaded end steady/pogo support to suit site conditions, recommended when equipment is added to the boom. It is recommended that the barrier is secured to the foundations using 4 nos M12 x 160mm chemical anchors. The installation of ducts for cabling is dependant upon the control criteria.
