Manac has announced that The Holland Group’s CB400 trailer air-ride suspension/slider system is now standard on its tandem van trailers. The CB400 was launched as Holland’s standard van trailer suspension in 2004. It features ‘SwingAlign’, said to be a very fast and convenient axle alignment system; an advanced thin-wall cast trailing arm for optimized strength and reduced weight; and ‘PosiLok’, a dock-walk and squat solution. The system also features high-strength slider technology that provides unmatched durability and the ‘QWIKRELEASE’ pin-pull system that allows one person to reposition the slider and eliminates bound-up lock pins.
