Gritex offers three types of vehicle mounted gritters, we can offer poly tow bar mounted spreaders, or either poly or stainless steel spreaders for vehicle or trailer mounting. All of these gritters have in cab controllers and are driven from the 12 volt vehicle electrics. In addition they are supplied with vibrate motors to avoid 'bridging' of damp/wet salt or grit, so that they can effectively spread grit onto icy surfaces.
