The M60 AVLB is a Cold War era bridge layer of US origin. It was developed in the 1960's to support the Patton series main battle tanks in the field. Initial development was based on the M48 Patton chassis, but subsequently switched to the M60 Patton for the production vehicles.
The M60 AVLB is based on the chassis of the M60 or the M60A1 main battle tank. The driver and commander are seated in what would normally be the turret ring. Instead of a turret launching equipment for a scissor bridge is fitted. A scissor bridge is carried in folded position on top of the chassis. It is launched towards the front by means of a hydraulically operated launching arm. The launching arm features a large bar that features as a large outrigger during emplacement.
The scissor bridge features a single hinge and has a 19 m length. The bridge has a 54 t weight capacity and support both wheeled and tracked vehicles. Emplacement time is 3 minutes, retrieval takes at least 10 minutes. Bridges cannot be joined to increase span.
The tracked M60 tank chassis provides good all terrain mobility, albeit at limited speeds. The 750 hp diesel engine provides a maximum road speed of 48 km/h.
The M60 AVLB was acquired by the US Army and US Marine corps. It was also exported to a handful of nations that also used the Patton series of tanks. The M60 AVLB remains in use around the world. With US forces it is to be replaced by AVLB's based on the M1 Abrams chassis.
M48 AVLB: Early development models were based on M48, M48A1, M48A2 Patton chassis. Some foreign M48 chassis have been converted as well.
M60 AVLB: AVLB system based on M60 Patton chassis.
M60A1 AVLB: AVLB system based on M60A1 Patton chassis.
