132 CHAVRE Chieftain Vickers AVRE conversion 1/35 beta
Following on from the Wilich AVRE Vickers were tasked with making a factory model. Here is my interpretation of this including hi-ab type crane. The CHAVRE typically carried Fascines that were tipped or winched off and pushed with a dozer blade. Hydraulic rams were used on the front and rear frames to raise and lower.

Come 1969, the design of the Chieftain AVRE had been completed and two prototypes with No. 7 bridges were ordered. The basic configuration of the AVRE was similar to that of the Chieftain ARV (Armoured Recovery Vehicle) which was under simultaneous development and was equipped with the 3-ton winch and a dozer blade/earth bucket. The No. 7 Bridge was carried driving surface-down on top of the hull.
Development on the AVRE ceased in April 1969.
By the mid-1980s, the Royal Engineers were even more eager to replace their now almost 40-year old Centurion AVREs. Also at this time, the Chieftain’s replacement, the Challenger I had started to be put into service. Realizing that a number of surplus Chieftain tanks would become available, the Chieftain AVRE program was resurrected. It would have the ability to mount the standard-issue dozer blade or a modified version of the Centurion 105 AVRE’s mine plow. It could tow two four-wheel ‘AVRE Trailers’ or two Giant Viper (GV) mine clearing devices, doubling the capacity compared to the Centurion. On a UK road it was limited to 1 trailer however.
Atop the turretless hull, a three-piece superstructure was added. Known as the ‘roof-rack’ or ‘hamper’, it could carry three PVC ‘maxi’ pipe fascine rolls or six roles of Class 60 Trackway. Six welded legs secured the rack to the hull, the rearmost rack was fixed in place, but the back section of the middle and the front section of the forward rack could be raised or lowered hydraulically to drop fascines or Class 60 rolls off the front of the vehicle. It was also decided that the rack be capable of carrying a No. 9 Tank Bridge and other stores.
The AVRE could haul one or two 7½-ton four wheel trailers that were designed to carry a fascine roll, two rolls of Class 60 Trackway, demolition charges, No. 7 Anti-Tank mines, RDD (Radiological Dispersal Device) explosives, and other engineering equipment. The trailer could traverse any terrain the tank could, without hindering it. It could be jettisoned when required via an exploding pin in the jointed towing hook.
Another trailer borne-device which was towed by the AVRE. A further development of the World War Two ‘Conger’, the ‘Giant Viper’ was a mine clearing device use to clear large areas of explosive devices such as IED’s or landmines, or clear a path through barbed wire. The Viper was mounted on a trailer that was towed by the tank. The Python was also used as is shown on the Museum site photo wrongly labelled as Vipers.
