Chaiseri is well known as a key supplier of tracks for armoured fighting vehicles (AFVs) and has exported to some 37 countries. It can supply tracks for lighter AFVs such as the Alvis Scorpion light reconnaissance vehicle, up to main battle tanks.
One of the more recent developments is the Chaiseri Runflat System, which is now in quantity production and provides a ‘get home’ capability for AFVs when their tyres have been damaged through enemy action. According to Chaiseri, trials have shown that its SPRH 395/85-R20 14.00-R20 single-piece run-flat heavy-duty system will enable the vehicle to travel a maximum distance of 3km when the vehicle is being driven at maximum speed on the road. When being driven at a slower speed, the range is increased. For example, at a speed of 50km/h the range is 22km, which increases to 75km when driven at a slower speed of 25km/h. The cross-country test has shown that the vehicle can travel for two hours at a maximum speed of 30km/h.
Chaiseri has also upgraded and overhauled wheeled and tracked AFVs and has designed the First Win (4x4) multi-purpose AFV, which is already in service with the Royal Thai Army and the Thai Ministry of Justice.
First Win is a 4x4 vehicle with a gross vehicle weight (GVW) of up to 13 tonnes and, in addition to the driver, can carry up to 10 dismounts, with various seating options. It is powered by a 300hp Cummins engine coupled to an Allison 3000 SP automatic transmission.
Ballistic protection is to STANAG 4569 Level II and mine protection to Level 3b under the hull centre, which is 8kg of explosive and Level 4a (10kg of explosive) under any station.
Chaiseri has signed an agreement with DEFTECH of Malaysia under which the First Win is being offered to meet the future operational requirements of the Royal Malaysian Army under the local designation of AV4. This latest vehicle is called the First Win E and is slightly more compact.
It has a GVW of 10 tonnes, and is powered by a 250hp Cummins engine coupled to an Allison 2500 automatic transmission. The First Win E is already undergoing company trials.
